The Poconos definitely got into the 30s, do you have a low temp for MPO Chris?

 

MPO made it down to 41° at the end of August which was the coldest since 2000. But not really that cold prior to 2000. The drier conditions allowed them to make it to the 11th coldest reading for August.

The warmth back in June was more impressive. It was their first June 93° maximum temperature.

58 / 56 - partly sunny today.  Upper 70s / low 80s.  Overall warmer the next week / through Friday.  Onshore pushing in along the coast, ridge above and cutoff below into the SE with ridge north.   Warmest days Sun (9/13) and Fri 9(19) mid 80s in the hottest spots perhaps warmer.   Mid week cut off ULL is in the SE / GFS more north so perhaps clouds and showers making it north, especially in southern section.  Looks like we have some semblance of a cut off / front come through from the GL/MW next weekend 20-21 and a brief period near/below normal. Overall warmer beyond there.

Historical:

 

1823: A strong category 1 or low category 2 hurricane struck near New Orleans, Louisiana and went toward Baton Rouge. Its strongest impacts occurred west of New Orleans.

 

1922 - The temperature at El Azizia in Libyia soared to 136 degrees to estbalish a world record. To make matters worse, a severe ghibi (dust storm) was in progress. (The Weather Channel)

1928 - Hurricane San Felipe crossed Puerto Rico resulting in the highest winds, the heaviest rains, and the greatest destruction in years. The hurricane produced much damage in the Virgin Islands, and later hit the Bahamas and Florida. (David Ludlum)

1934: The mercury soared to 92 degrees at Seattle, WA, a record for September. (The Weather Channel)

1944: Hampton Roads saw winds of 72 mph gusting to 90 mph. Richmond had 3.26 inches of rain on the 13th. Winds of 134 mph sustained with gusts to 150 mph lashed Cape Henry a wind record which remains standing today for the state.Virginia Beach saw the pressure fall to 28.80". Rainfall from the storm caused a flood of record at State Farm on the James river (26.4 feet).Damage totaled $2.5 million. Forty-six perished. This system was the first time that air force reconnaissance air craft were used to monitor a storm threatening the East Coast. Rec. Major east coast storm Sep. 13-15th

1944: The destroyer USS Warrington was sunk by the Great Atlantic Hurricane 300 miles east of Cape Canaveral, Florida. 247 men were lost in the tragedy.  

1978: Little Rock, Arkansas saw 8.10 inches of rain which caused major flash flooding. Ten people were killed. 

1984 - Hurricane Diana, after making a complete loop off the Carolina coast, made landfall and moved across eastern North Carolina. Diana deluged Cape Fear with more than eighteen inches of rain, and caused 78 million dollars damage in North Carolina. (Storm Data)

 

1987 - Showers and thunderstorms produced heavy rain in the northeastern U.S. Flooding was reported in Vermont, New York, Pennsylvania and New Jersey. Greenwood NY received 6.37 inches of rain. A dike along a creek at Prattsburg NY gave way and a two million dollar onion crop left on the ground to dry was washed away. The prolonged rains in the eastern U.S. finally came to an end late in the day as a cold front began to push the warm and humid airmass out to sea. (The National Weather Summary) (Storm Data)

1988 - Hurricane Gilbert smashed into the Cayman Islands, and as it headed for the Yucatan peninsula of Mexico strenghtened into a monster hurricane, packing winds of 175 mph. The barometric pressure at the center of Gilbert reached 26.13 inches (888 mb), an all-time record for any hurricane in the Carribean, Gulf of Mexico, or the Atlantic Ocean. Gilbert covered much of the Gulf of Mexico, producing rain as far away as the Florida Keys. (The National Weather Summary) (Storm Data)

1989 - Unseasonably cool weather prevailed over the Central Plains Region, with a record low of 29 degrees at North Platte NE. Unseasonably warm weather prevailed across the Pacific Northwest, with a record high of 96 degrees at Eugene OR. Thunderstorms over south Texas produced wind gusts to 69 mph at Del Rio, and two inches of rain in two hours. (National Weather Summary)

1993: A strong, winter-type storm moving through the Rockies and the western Plains produced record early season snowfall. Denver, Colorado recorded 5.4 inches of snow for its greatest snowstorm ever for so early in the season, after reaching 92 degrees the day before. The same record was also set at both Cheyenne, Wyoming and Scottsbluff, Nebraska with 5.5 and 2.5 inches of snow, respectively. Along with the snow came record lows including: Cheyenne, WY: 29°, Rapid City, SD: 29°-Tied, Colorado Springs, CO: 32°-Tied and Denver, CO: 33°. (Ref. AccWeather Weather History)

1994: Microburst winds of 100 mph removed the roof above 8 classrooms of the Littleton Elementary School in Cashion, AZ; 8 children/1 teacher were injured. The same storm littered the ground with golf ball-size hail and knocked down a mile-long stretch of power poles. (Ref. Weather Guide Calendar with Phenomenal Weather Events 2011 Accord Pub. 2010, USA)

1996: Hurricane Fausto moved across Baja on Friday night the 13th and continued moving north-northeastward, striking mainland Mexico early Saturday morning. (Ref. AccWeather Weather History)

1998: Heavy rain of 5 to 12 inches fell over portions of extreme southeast Kansas. Unofficial reports of rainfall amounts as high as 14 inches was reported in Bourbon County, Kansas. The hardest hit areas were along the Marmaton River in Bourbon County including Ft. Scott. The highest estimated stage of the Marmaton River at Ft. Scott reached 50.05 feet on the 14th which is the second highest stage ever recorded. (Ref. Wilson Wx. History)

1999: Hurricane Floyd on the verge of Category 5 status steamed steadily westward about 250 miles east of Miami. Forecasters warned that Floyd was much more dangerous than 1992's Hurricane Andrew due to its size. (Ref. Wilson Wx. History)

2007: Hurricane Humberto made landfall just east of High Island, TX in the McFadden National Wildlife Refuge. Hurricane Humberto had maximum sustained winds near 90 mph and a minimum pressure of 985 millibars or 29.09 inches of mercury. Humberto made history due to its rapid intensification from a tropical depression the morning of September 12th, to a hurricane early on this date, as no other hurricane has ever strengthened so quickly close to landfall. Damage was estimated near $60 million dollars. Only five other storms in Atlantic Basin history has grown from a depression to a hurricane within 24 hours: Arlene & Flora in 1963, Blanche in 1969, Celia in 1970 (from depression to a Category 3) and Harvey in 1981. (Ref. Wilson Wx. History)

2008: Hurricane Ike made landfall around 0700z along the northern end of Galveston Island, TX as a strong Category 2 storms with maximum sustained winds of 110 mph and a minimum central pressure of 28.14 inches of mercury. Prior to landfall, Ike covered an extensive area of the Gulf of Mexico with the largest radii of hurricane-force winds: 125 miles out from the center and tropical-storm force winds: 275 miles out from the center, ever measured. Much of Galveston and nearby coastal towns were left in shambles, and storm-surge damage extended well east into Louisiana. Ike resulted in 103 deaths across Hispaniola, Cuba and parts of the United States Gulf Coast and total damage at $32 billion dollars. (Ref. Wilson Wx. History)

2014: The 3rd of the top 10 US weather events according to Weatherwise magazine was the Boulder Colorado flash flood of September 9th through the 16th. This deluge dumped more than 9 inches of precipitation in 24 hours and 14 inches in four days on Colorado foothills unleashing furious flooding on Boulder and the surrounding towns. It damaged and destroyed 1800 homes, and washed out hundreds of miles of road, and cost $2 billion. (Ref.Weatherwise May/June 2013 page 15)

2017: Irma started on August 30th and reached its peak on Sep. 6th and hit FLA. on Sunday night Sep. 10th, 2017. On September 6, Irma reached its peak intensity with 185 mph (295 km/h) winds and a minimum pressure of 914 hPa (27.0 inHg), making it the strongest tropical cyclone worldwide so far in 2017. Another eyewall replacement cycle caused Irma to weaken back to a Category 4 hurricane, but the storm attained Category 5 status for a second time while making landfall in Cuba. After dropping to Category 3 intensity due to land interaction, the storm re-intensified to Category 4 as it crossed warm waters between Cuba and Florida before making landfall on Cudjoe Key with maximum sustained winds of 130 mph (215 km/h). Irma dropped back to Category 3 by the time it made a second Florida landfall on Marco Island


2018: Hurricane Florence was a powerful and long-lived Cape Verde hurricane, as well as the wettest tropical cyclone on record in the Carolinas and the ninth-wettest tropical cyclone to affect the contiguous United States. The sixth named storm, third hurricane, and the first major hurricane of the 2018 Atlantic hurricane season, Florence originated from a strong tropical wave that emerged off the west coast of Africa on August 30, 2018. Steady organization resulted in the formation of a tropical depression on the next day near Cape Verde. Progressing along a steady west-northwest trajectory, the system acquired tropical storm strength on September 1, and fluctuated in strength for several days over open ocean. An unexpected bout of rapid intensification ensued on September 4– 5, culminating with Florence becoming a Category 4 major hurricane on the Saffir–Simpson scale with estimated maximum sustained winds of 130 mph

2008: Hurricane Ike made landfall as a Category 2 storm near Galveston, Texas. 

2017: The NWS Office in Reno, Nevada, issued their first tornado warning since July 21st, 2014.

The 1922 136° temperature at El Azizia was decertified by the WMO in 2012. The WMO found "five major concerns with the 1922 El Azizia temperature extreme record, specifically 1) potentially problematical instrumentation, 2) a probable new and inexperienced observer at the time of observation, 3) unrepresentative microclimate of the observation site, 4) poor correspondence of the extreme to other locations, and 5) poor comparison to subsequent temperature values recorded at the site."

Both hotter extremes and colder extremes and drier weather-- I LIKE!!

Are you switching around to my view that we are now headed directly into an -AMO even if it doesn't show it on indices?

Two years in a row with drier summers and falls and lackluster or nonexistent tropical cyclone activity in the Atlantic.  I think we might be headed to another dry and coldish winter, just like last winter too.

 

 

[Sundog]

The EURO AI has been bringing rain from the coastal low for many runs now and now the GFS brings some rain up here this way as well. 

But the regular Euro refuses to budge and is basically dry. 

[the_other_guy]

Anyone else find it humid out?

58 / 56 - partly sunny today.  Upper 70s / low 80s.  Overall warmer the next week / through Friday.  Onshore pushing in along the coast, ridge above and cutoff below into the SE with ridge north.   Warmest days Sun (9/13) and Fri 9(19) mid 80s in the hottest spots perhaps warmer.   Mid week cut off ULL is in the SE / GFS more north so perhaps clouds and showers making it north, especially in southern section.  Looks like we have some semblance of a cut off / front come through from the GL/MW next weekend 20-21 and a brief period near/below normal. Overall warmer beyond there.

The 1922 136° temperature at El Azizia was decertified by the WMO in 2012. The WMO found "five major concerns with the 1922 El Azizia temperature extreme record, specifically 1) potentially problematical instrumentation, 2) a probable new and inexperienced observer at the time of observation, 3) unrepresentative microclimate of the observation site, 4) poor correspondence of the extreme to other locations, and 5) poor comparison to subsequent temperature values recorded at the site."

I could imagine the welcoming sign driving into El Azizia, "El Azizia - Home of the False Highest Temperature Never Recorded"...

82 / 58 a bit more clouds now than earlier this morning

 

[donsutherland1]

Through today, September 2025 has seen just two days with highs of 80° or above in Central Park. The last time there were as few such days during the September 1-13 period was 2009.

Tomorrow will be somewhat warmer with widespread highs in the lower 80s.

Temperatures will top out in the upper 70s to perhaps lower 80s on Monday and Tuesday. Similar conditions could prevail on Wednesday and Thursday. A cutoff system near the Delmarva could bring some showers or rain to parts of the Jersey Shore and eastern Long Island on Wednesday into Thursday.

September 1-15 remains on track to achieve a solid cool anomaly. Since 2000, there have been nine years that saw a cooler than normal first half of September. Two-thirds of those years went on to record a warmer than normal second half of September. Only two of those years (2017 and 2019) wound up with a monthly mean temperature of 70.0° or above. Overall, for two-thirds of those years, the cool start was sufficiently cool to produce a cooler than normal monthly anomaly. The last year that saw both a cooler than normal first half and second half of September was 2009. Prior to that, it was 2001. The last year to record a cooler than normal first half of September followed by a warmer than normal September was 2024.

The ENSO Region 1+2 anomaly was -0.3°C and the Region 3.4 anomaly was -0.4°C for the week centered around August 27. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.33°C and the ENSO Region 3.4 anomaly has averaged -0.32°C. La Niña conditions will likely develop during mid- or late-autumn.

The SOI was -9.21 today. 

The preliminary Arctic Oscillation (AO) was +0.225 today. 

Based on sensitivity analysis applied to the latest guidance, there is an implied near 53% probability that New York City will have a cooler than normal September (1991-2020 normal). September will likely finish with a mean temperature near 69.0° (0.2° below normal). 

Supplemental Information: The projected mean would be 1.0° above the 1981-2010 normal monthly value.

1824: A hurricane storm surge swept over the islands of the Georgia coast with a great loss of life, destruction of crops, and severe floods inland. (Ref. Wilson Wx. History)

1912: Hurricane makes landfall just west of Mobile, Alabama. (Ref. AccWeather Weather History)

1919: 357 people died as a hurricane made landfall near Corpus Christi, TX. A 16 foot storm surge inundated the low-lying areas, destroying almost all of the wooden buildings. Port Aransas was almost totally demolished. Damage totaled $20.3 million dollars. (Ref. Wilson Wx. History)

1928: A violent, estimated F4 tornado, with winds of 200 mph, tore across Rockford, Illinois. The tornado first touched down 8 miles south-southwest of Rockford and moved across the southeast part of the city. The tornado was on the ground for 25 miles with a width varying from 200 to 500 feet. A total of 14 people were killed, with around 100 injuries reported in Rockford alone. Two hundred buildings were damaged or destroyed. 

1937 - The mercury soared to 92 degrees at Seattle, WA, a record for September. (The Weather Channel)

1944 - A very destructive hurricane swept across Cape Hatteras and Chesapeake Bay, side swiped New Jersey and Long Island, and crossed southeastern Massachusetts. The hurricane killed more than four hundred persons, mainly at sea. The hurricane destroyed the Atlantic City NJ boardwalk. (David Ludlum) (The Weather Channel)

1960: Hurricane Ethel developed rapidly in the central Gulf of Mexico early on this date, intensified and moved northward with winds estimated as high as 130 mph near the center late on this date. Ethel went from a tropical storm to briefly a Category 5 within 18 hours. Ethel decreased in intensity rapidly before reaching the coast near the Alabama- Mississippi border on the 15th as a minimal hurricane. Hurricane force winds were reported in Plaquemines Parish, Louisiana, including Venice which reported sustained winds of 90 mph and gusts of up to 105 mph. Rainfall totals ranged from 2 to 10 inches. Damage was estimated at $1 million dollars and no fatalities were reported. Despite attaining Category 5 intensity, Ethel name was not retired. (Ref. Wilson Wx. History)
 

1970 - The temperature at Fremont, OR, dipped to 2 above zero to equal the state record for September set on the 24th in 1926. (The Weather Channel)

 

1971: A strong ridge was in place across the west giving very high temperature included: Palm Springs, CA: 114°, Phoenix, AZ: 109°, Victorville, CA: 108°, Fresno, CA: 105°, Stockton, CA: 104°, Sacramento, CA: 103°, San Francisco (Airport), CA: 103°, Santa Ana, CA: 100°, Bishop, CA: 100°, Downtown Los Angeles, CA: 97°, Winslow, AZ: 95 °F. (Ref. Wilson Wx. History)
 

1977: Severe thunderstorms produced several tornadoes in eastern Arkansas, killing one. 

1982: Beginning the previous day, heavy early season snow blanketed parts of the northern Rockies. Totals included Red Lodge, MT: 36 inches, Mystic Lake, MT: 30 inches, Nye, MT: 15 inches, Sheridan, WY: 7 inches, Billings, MT: 6 inches and Joliet/Columbus, MT: 4 inches. (Ref. Wilson Wx. History)

1984: A lightning bolt struck a soccer field in West Goshen Township, PA. 26 people were injured and 4 hospitalized, including players, coaches, officials, and spectators. One of the hospitalized died 5 days later. (Ref. AccWeather Weather History)

1987 - Barrow, AK, received 5.1 inches of snow, a record for September. (Sandra and TI Richard Sanders - 1987)

1987 - Thunderstorms developing along a cold front produced severe weather from Minnesota to Texas. Thunderstorms in Iowa produced baseball size hail at Laporte City, and 80 mph winds at Laurens. Hail caused more than ten million dollars damage to crops in Iowa. Thunderstorms in Missouri produced wind gusts to 75 mph at Missouri City and Kansas City. A thunderstorm in Texas deluged the town of Fairlie with two inches of rain in just two hours. (Storm Data) (The National Weather Summary)

1988 - Hurricane Gilbert made the first of its two landfalls on Mexico, producing 170 mph winds at Cozumel. (The Weather Channel)

1988 - Thunderstorms produced severe weather over the Texas panhandle during the evening hours. One thunderstorm spawned a strong (F-2) tornado in the southwest part of Amarillo, and deluged the area with five inches of rain. The heavy rain left roads under as much as five feet of water, and left Lawrence Lake a mile out of its banks. Hurricane Gilbert lost some of its punch crossing the Yucatan Peninsula of Mexico. Its maximum winds diminished to 120 mph. (The National Weather Summary) (Storm Data)

1989 - Unseasonably cool weather prevailed across the south central U.S. Eight cities reported record low temperatures for the date, including Raton NM with a reading of 30 degrees. The afternoon high of 59 degrees at Topeka KS marked their third straight record cool maximum temperature. Unseasonably warm weather continued in the Pacific Northwest. Seattle WA reported a record eight days in a row of 80 degree weather in September. (Storm Data) (The National Weather Summary)

 

1992: A record early season snowstorm came to and end over the western Tanana Valley in central Alaska. 16.7 inches of snow fell at Fairbanks which set a new record for the greatest September snowstorm on record. Denali National Park was buried under 37.6 inches over the four day period and Eielson Air Force Base checked in with 23.5 inches. Along with the snow came record lows across parts of the state including: Barrow, AK: 13°, Delta Junction, AK: 23°, Nome, AK: 24°, Juneau, AK: 32°-Tied and Annette, AK: 38°. (Ref. Wilson Wx. History)

1993: Canadian high pressure behind a strong cold front brought record chill to parts of the central U.S. Some low temperatures included: Camp Crook, SD: 19°, Porcupine, SD: 19°, Rapid City, SD: 24°, Sheridan, WY: 24°, Colorado Springs, CO: 28°, Cheyenne, WY: 29°, Pierre, SD: 31°, Goodland, KS: 31°, Pueblo, CO: 31°, Denver, CO: 32 °F.

1997: A powerful thunderstorm unleashed a destructive wind that wreaked havoc on a small section of Bullhead City, AZ. The fierce wind snapped 24 power poles and damaged approximately 80 houses and mobile homes. 22 of the homes were condemned. (Ref. Wilson Wx. History)

1999: A powerful thunderstorm unleashed a destructive wind that wreaked havoc on a small section of Bullhead City, AZ. The largest peacetime evacuation in United States history was underway as 2.6 million residents of Florida, Georgia and the Carolinas were fleeing in advance of monstrous Hurricane Floyd. By days end, the Category 4 hurricane was battering the northern Bahamas packing winds of 135 mph with a minimum central pressure of 934 millibars or 27.58 inches of mercury.

1999: Drought emergencies and restrictions were lifted in NJ, from Burlington to Ocean Counties and to the S, after increasing rain ended a growing season drought that caused 80 million dollars in agricultural damage. Two days later the unprecedented rains of tropical storm Floyd effectively ended the drought, as up to 14.5" of rain fell, or about 4 months worth of normal rainfall.(Ref. Wilson Wx. History)

 

2005: Hurricane Ophelia caused some damage and beach erosion along the United States coastline from Florida to North Carolina. The closest approach occurred on September 14 and 15 with its western eyewall crossing land and the eye remaining just offshore in the Carolinas. Click HERE for more information from the NWS Office in Charleston, South Carolina.

 

2008: Hurricane Ike became extratropical on this day. The St. Louis Metropolitan Area experienced hurricane conditions, with Ike's remnants inflicting severe damage to homes. Several areas in Illinois and Indiana, already flooded by the frontal boundary to the north, saw significant additional rainfall. Due to flooding in Chicago, a state of emergency was declared for Cook County due to flooding of the Des Plaines River. Hurricane-force wind gusts were reported to the east of the center across parts of Kentucky, Indiana, Ohio, and Pennsylvania with significant wind damage including structural damage to buildings and trees.

2011: The remains of Hurricane Ike brought flooding rains/high winds/power losses to the St. Louis, MO, area. In Ladue, MO a woman died when lightning hit a tree and a large limb fell on her; in University City 2 people drowned while trying to move their cars to higher ground. (Ref. Weather Guide Calendar with Phenomenal Weather Events 2011 Accord Pub. 2010, USA)
 

 

2017: Irma is among the strongest Atlantic hurricanes on record based on wind speed. The major hurricane could notch more historic moments in the days ahead. Hurricane Irma is one of the most powerful hurricanes to roam the Atlantic Basin in more than a decade, and it could hit more historical benchmarks in the days ahead. Here's a rundown of Irma's notable extremes so far. Strongest Winds in Almost 12 Years Irma's maximum sustained winds have so far maxed out at 185 mph. Those winds are well above the 157 mph Category 5 threshold and are the highest registered in any Atlantic hurricane since 2005. Hurricane Wilma on Oct. 19, 2005, was the last hurricane to have maximum sustained winds reach 185 mph. Incredible #GOES16 imagery of Category 5 Hurricane #Irma with 185 mph max wind speeds. 10:36 PM - Sep 5, 2017 One of Four Hurricanes With 185+ MPH Winds The 185 mph winds also place Irma in the upper echelon of Atlantic hurricanes based on wind speed. Only three other hurricanes have had winds of 185 winds or greater, including Wilma (2005), Gilbert (1988) and Allen (1980), according to Dr. Phil Klotzbach, a tropical scientist at Colorado State University. Allen had the strongest winds of those four hurricanes, maxing out at 190 mph in early August 1980. Records that Irma set

2018: Hurricane Florence was a powerful and long-lived Cape Verde hurricane, as well as the wettest tropical cyclone on record in the Carolinas and the ninth-wettest tropical cyclone to affect the contiguous United States. The sixth named storm, third hurricane, and the first major hurricane of the 2018 Atlantic hurricane season, Florence originated from a strong tropical wave that emerged off the west coast of Africa on August 30, 2018. Steady organization resulted in the formation of a tropical depression on the next day near Cape Verde. Progressing along a steady west-northwest trajectory, the system acquired tropical storm strength on September 1, and fluctuated in strength for several days over open ocean. An unexpected bout of rapid intensification ensued on September 4– 5, culminating with Florence becoming a Category 4 major hurricane on the Saffir–Simpson scale with estimated maximum sustained winds of 130 mph - Florence A Write-Up For The Whole Storm

 For reference, the ECMWF and EPS have been running a fairly strong warm bias in the short range.

Meanwhile, the ECMWF continues to rank first in 500 mb anomaly scores:

 

This divergent outcome is a reminder that there is more to forecasting than 500 mb maps. All the details matter.

With no cool downs in sight September might average seasonable if not slightly above normal no? Much warmer looking nights ahead as well.
