A tad chilly out this morning! 

[SACRUS]

68 / 57 another gorgeous day on tap  Warmer the next 48 hours  mid - upper 80s maybe a stray 90 in the hot locations inland, ahead of a front that could bring some showers, storms or scattered rain / clouds on thursd.  A period of near normal this upcoming weekend before ridge comes east and where it builds will be key in how much warmth can push into the northeast from mid month (next week). Overall warmer in the period beyond Sunday.

Historical:

 

1900 - The greatest weather disaster in U.S. records occurred when a hurricane struck Galveston TX. A tide fifteen feet high washed over the island demolishing or carrying away buildings, and drowning more than 6000 persons. The hurricane destroyed more than 3600 houses, and total damage was more than thirty million dollars. Winds to 120 mph, and a twenty foot storm surge accompanied the hurricane. Following the storm, the surf was three hundred feet inland from the former water line. The hurricane claimed another 1200 lives outside of the Galveston area. (8th-9th) (David Ludlum) (The Weather Channel)

 

1900: A Category 4 storm made landfall in Galveston, Texas on this day in 1900. This hurricane killed between 6,000 and 12,000 individuals, making it the deadliest US Atlantic hurricane on record. The highest point in the city of Galveston was less than nine feet above sea level. The hurricane brought a storm surge of over 15 feet, which overwhelmed the entire island.

 

1925: In September 1925, South Carolina was in the middle of one of the most widespread and disastrous droughts in the state's history. The NWS Co-op station in Calhoun Falls reported 11 days above 100°F with a maximum temperature of 111°F on this day.

 

1987 - A tropical depression off the coast of South Carolina brought another round of heavy rain to the Middle Atlantic Coast Region and the Upper Ohio Valley. Showers and thunderstorms produced extremely heavy rain in eastern Pennsylvania, where flooding caused more than 55 million dollars across a seven county area. The afternoon high of 97 degrees at Miami FL was a record for the month of September. (The National Weather Summary)

1988 - Eighteen cities in the south central and eastern U.S. reported record low temperatures for the date, including Roanoke VA with a reading of 42 degrees. (The National Weather Summary)

1989 - Thunderstorms developing along a stationary front produced very heavy rain in the central U.S. Thunderstorms during the late morning and afternoon produced five to nine inches of rain around Lincoln NE, with an unofficial total of eleven inches near Holmes Park. Up to six and a half inches of rain soaked northern and western Iowa. Eighty to ninety percent of the homes in Shenandoah IA, where 5.89 inches of rain was received, reported basement flooding. (The National Weather Summary) (Storm Data)

 

1998: A severe thunderstorm developed over the southern end of the Las Vegas Valley in Nevada. The storm moved north bringing damaging winds and heavy rain mainly across the eastern half of the metro area. Henderson Executive Airport recorded wind gusts of 80 mph. Air traffic control personnel temporarily evacuated the airport tower. Approximately 15 homes and trailers in Moapa were severely damaged by thunderstorm winds estimated at 80 to 90 mph.

 

2012: Severe storms impacted the New York City area, forcing a delay of the United States Open. A tornado hit a beach club in Queens, and another brought damage to Canarsie, Brooklyn, New York.

Still to see where the ridge forms mid month for a warmer period - 9/14 - 9/18th tendency has been more SW and we ride the periphery, but there have been several runs between and back and forth from the gfs and eur on a more expansive EC ridge.  Whatever warmup we realize the period beyond the 18th looks to have a brief but crisp cooldown in the period till the equinox.

 

[bluewave]

Next 10 days look warmer than average with perhaps some cooler readings day 11-15.

The wind is incredibly calm right now considering the sun is still out

Another great day. High 80, low 58

I know but look at it this way. The Yankees need to hit home runs to win games and it's easier to hit home runs in hotter weather.

Many spots in the Northeast are in the top 5 or 10 for 80° days through September 5th with the early start back in March. 
 

 

 

Our local forecasters have said that 10 of the last 14 days have been below normal. It just hasn't been hot since July 15th. 80 degrees is an easy bar to clear in the summer as long as it's sunny and we are finally in a nice dry stretch with just an occasional frontal passage.  I think we'll finally get a nice dry month now.

Depends where - EWR has 41 90 degree days in 1991 and 40 in 2016 and also 41 in  2021

Tony did 1993 tie 1991 there or exceed it?

Temperatures will likely peak in the lower and middle 80s tomorrow and Thursday. Another push of cooler air could arrive by Friday or Saturday.

Overall, the week looks to be dry with little or no rainfall likely through at least Friday. the greatest likelihood for some showers is Thursday evening and Thursday night when a cold front crosses the region.

The ENSO Region 1+2 anomaly was +4.6°C and the Region 3.4 anomaly was +2.7°C for the week centered around September 2. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +4.12°C and the ENSO Region 3.4 anomaly has averaged +2.57°C. The ongoing strong El Niño, will continue to strengthen through the mid-fall.

The SOI was -26.74 today.

The preliminary Arctic Oscillation (AO) was +1.761 today. 

Based on sensitivity analysis applied to the latest guidance, there is an implied near 58% probability that New York City will have a warmer than normal September (1991-2020 normal). September will likely finish with a mean temperature near 69.9° (0.7° above normal). The Region 1+2 anomaly surpasses the all-time record of +4.5° that was set during the week centered around June 29, 1983. 

Supplemental Information: The projected mean would be 1.9° above the 1981-2010 normal monthly value.

So as of right now EWR isn't even in the top 20 for 90 degree days.

Also pretty insane that 1993 had nearly as many 95 degree days as we do 90 degree days this year.  Now that's hot.

MPO has been fairly warm for September so far at +3.3°. The warm minimums are driving the departures there like in other places.

The min departure is +4.0° and the max +2.7. You guys have only dropped to 47° by 9-8 which  is the 2nd warmest low on record by September 8th.

NYC is actually doing a little better than you guys by falling to 61° which is 3rd warmest.

So this isn’t a UHI issue since all locations are experiencing warm minimums regardless of rural or urban settings.

I had that 47 here too in late August, it felt cold! My temperature is always within a degree or two of MPO  even though I'm south of there and about 300 feet lower in elevation. Those tv mets I quoted use Avoca airport for their stats it's always a few degrees warmer there.

I think the UHI effect comes into play with high population density and houses right next to each other. It does not allow for proper siting of weather equipment.  That's the only way I can explain the 107-105-104 three days at a VP2 weather station in Valley Stream in early July when JFK was 102-100-100 for the same three days.  That Davis unit even reached 101 on that smoke filled July 15 when the smoke stopped JFK from reaching 100 for a record breaking 4th day when they were stopped at 98 on that day.

Never got above 94 here and I think MPO peaked at 93.

[donsutherland1]

Temperatures will likely peak in the lower and middle 80s tomorrow. A shower is possible tomorrow evening or tomorrow night. Another push of cooler air could arrive by Friday or Saturday. Highs on both days will likely peak in the upper 70s.

The longer-term outlook has grown somewhat warmer through the middle of next week. In general, the temperature should top out in the upper 70s and lower 80s through the middle of next week.

The ENSO Region 1+2 anomaly was +4.6°C and the Region 3.4 anomaly was +2.7°C for the week centered around September 2.

Based on sensitivity analysis applied to the latest guidance, there is an implied near 63% probability that New York City will have a warmer than normal September (1991-2020 normal). September will likely finish with a mean temperature near 70.2° (1.0° above normal).

1821: A tornadic outbreak affected the New England states of Massachusetts, New Hampshire, and Vermont on this day. Five tornadoes reportedly touched down from this event. One storm in New Hampshire had a path width of a half mile and tracked an estimated 23 miles. This tornado killed at least six individuals, which could be the deadliest tornado in New Hampshire history. 

1881: For the first time in 33 days, rain fell at Washington, DC. (Ref. for 33 day drought in 1881 )

1889: A hurricane that formed east of the Antilles moved north and then northward toward New Jersey. The storm came within 150 miles of Atlantic City, NJ before becoming nearly stationary for 4 days. The storm, one of the greatest storms to affect the shore and ocean, then turned to the southwest toward Norfolk, VA, and dissipated. Atlantic City measured a gust to 100 mph on the 10th. At Philadelphia, PA, rain began on the 10th. This began a period of 12 consecutive days of measurable rain, with a final total of 3.70 inches. Another sudden and damaging storm surge hit Long Island, NY and the Jersey shore during the evening on the 10th, following the 1st surge that hit on the 8th. The storm was located south of Cape Cod and east of Norfolk, VA, when the surge moved in. 29 ships were sunk in the Delaware Bay, killing at least 31 sailors. Officially, 40 lives were lost attributed to this hurricane. (Ref. Wilson Wx. History)

1919: 300 lives were lost mostly in ships near Key West, where winds were reported at 110 mph as a violent hurricane caused considerable damage. Brick structures had walls blown out and large vessels were torn from their moorings and blown on banks. A tornado destroyed six buildings and damaged 19, injuring six people at Goulds in Dade County. This hurricane killed hundreds more on its track to south Texas. The final death toll of over 600 was mostly in ships at seas. (Ref. Wilson Wx. History)

1964: Hurricane Dora, the first storm of hurricane intensity to cross into northeast Florida from the Atlantic in 80 years of record keeping, moved inland over St. Augustine early on the 10th. St. Augustine was in the eye of the storm and recorded a sea level pressure of 966 millibars or 28.52 inches of mercury. Dora produced sustained winds of around 100 mph, and abnormally high tides to almost all coastal points north of Daytona Beach. Highest sustained winds, from the southwest, and estimated at 125 mph were reported at St. Augustine. Sustained winds of 82 mph were recorded in Jacksonville, and this was the first time in Weather Bureau history that winds of full hurricane force have been observed in Jacksonville. Storm tides reached 12 feet at St. Augustine and ranged between 5 and l0 feet above normal north of Daytona Beach. High winds in the Jacksonville area caused a massive utilities failure. One death and 8 injuries were reported from Dora. (Ref. AccWeather Weather History)
 

 

1965: Hurricane Betsy slammed into New Orleans on the evening of September 9, 1965. 110 mph winds and power failures were reported in New Orleans. The eye of the storm passed to the southwest of New Orleans on a northwesterly track. The northern and western eyewalls covered Southeast Louisiana and the New Orleans area from about 8 PM until 4 AM the next morning. In Thibodaux, winds of 130 mph to 140 mph were reported. The Baton Rouge weather bureau operated under auxiliary power, without telephone communication.

San Gorgonio, 10.13 inches at Mt. Laguna, 8 inches at Mt. San Jacinto, Over 4 inches in the Little San Bernardino Mountains, and 1.8 to 2.8 inches in the Coachella Valley. Deep Canyon (above La Quinta) recorded 2.96 inches in three hours on the 10th. Rainfall in the Santa Rosa Mountains above the Coachella Valley was called the “heaviest in recorded history.” Six were buried and killed in sand in Ocotillo. (Ref. Wilson Wx. History)

1983: On this date through the 10th, strong winds blasted through east central South Dakota, leaving in its wake damaged crops, hundreds of downed trees, broken windows, damaged roofs and buildings, downed power poles, and damaged vehicles. Gusts of up to 75 mph in Huron moved a semi trailer one-half block into a truck. Standing crops of corn, beans, and sunflowers suffered extensive damage in many areas with losses up to 50% reported. (Ref. Wilson Wx. History)

1986: An F-16 fighter jet had its windshield cracked by hail on its return to the Eagle Range Training Grounds near UT’s Great Salt Lake.
