This is MUCH better than yesterday was.

I'll tell you though, it felt great running in 69 degrees and cloudy yesterday. Not nice weather obviously, but great for outdoor exercise.

Wouldn't surprise me if Sunday ends up cloudy with a few showers around.  But otherwise looks nice

Is "nice" to you 40 inches of snow per hour?

[Snowlover11]

Disgusting outside. And of course storms falling apart on arrival.

[bkviking]

We need at least 2 weeks of uninterrupted sunshine. I'm going to enjoy hearing people who whined about this summer being hot are shocked when next summer is 3-5 degrees hotter.  This wasnt a hot summer, mostly just humid and wet. We better hit 90 for my birthday on September 15th!

In terms of 95°+ days it was a pretty high ranking for many locations. Areas away from the sea breeze made it to 35 days of 90° and over 40 days at the Philly stations.

But this would have been a cooler summer in the past during developing super El Niños.

Most summers following super El Niños had more heat than the one while it was still developing like this year. So we would expect more heat than this one during the next few summers. 

Since the ridge axis this summer was out near 100W, the strongest heat this summer in our region was from Philly to ACY. We have been getting the stalled fronts with too much convection here to have the kind of heat areas just to our south did. 

The start of September looks like more of the same with the main heat dome staying to our west. Maybe we can get a day or two next week near 90° but it could stay closer to Philly.  

Have a very happy birthday coming up. You pick the perfect spot at a higher elevation which is cooler than areas just to your south and east.

Summer 2026 heat dome centered near 100W

 

Next 10 days look like more of the same

Past developing super El Niño summers have been much cooler with more troughs than ridges

Only for a few more hours

[Brian5671]

another storm overnight-about .40   The wet summer continues

[SACRUS]

80 / 72 sunny.  Warm one mid upper 80s and a stray 90 in the hottest spots inland in NJ.  Onshore flow attributed to cut off trough in ME this weekend brings what should be a cooler but mainly dry Labor day weekend but these ULL always seem to create more clouds moving Nrth to South and even showers into NE sections and LI - id bet Sunday may not be as clear as advertised but here is hoping that thinking is wrong.  Otherwise once to Monday near normal week 9/7 - 9/14 with a couple of warm days 9/9-9/10 then back near normal.  9/15 and beyond pressing overall warmer as ridge again comes east and position will be key.

Historical:


1766: A hurricane made landfall at modern-day Galveston, Texas. The following is from David Roth of the Weather Prediction Center. “A mission, named San Augustine de Ahumado was located in what is nowadays known as Chambers County. This mission was destroyed and subsequently abandoned. A seven-foot storm surge put the area under water. A richly-laden treasure fleet of 5 galleons en route from Vera Cruz to Havana was driven ashore and had to wait many weeks for assistance to come. La Caraqueña wrecked on Galveston Island while El Nuevo de Constante sank along the western Louisiana coast. Fortunately, much of the treasure and people aboard were saved.”

1939 - A thunderstorm deluged Washington D.C. with 4.4 inches of rain in two hours. September of that year was very dry across much of the nation, and Washington D.C. received more rain in that two hour period than most other places in the country that entire month. (David Ludlum)

 

1941: A violent tornado ripped through Northeast and North Minneapolis shortly afternoon on this day. The hardest-hit location was the Soo Line Railroad’s Shoreham Yards where four people died, and at least 50 were injured. The death toll at Soo Line could have been higher, but the tornado struck five minutes after the lunch bell went off, meaning 100 men left the shops.

1945: Record heat blasted parts of the Southwest into the Plains. The high of 108° established the record high for the month of September at Liberal, KS. Other daily records included: Yuma, AZ: 116°, Phoenix, AZ: 112°, Las Vegas, NV: 109°, Tucson, AZ: 106 °F. (Ref. Wilson Wx. History)

1965: Hurricane Betsy stalled 350 miles east of Jacksonville, FL just before the busy Labor Day holiday weekend, causing major headaches for weather forecasters. (Ref. AccWeather Weather History)

1970 - The greatest natural disaster of record for Arizona occurred. Unprecedented rains caused rivers in central Arizona to rise five to ten feet per hour, sweeping cars and buildings as far as 30 to 40 miles downstream. Flooding claimed the lives of 23 persons, mainly campers, and caused millions of dollars damage. Water crested 36 feet above normal near Sunflower AZ. Workman's Creek was deluged with 11.40 inches of rain in 24 hours to establish a state record. Moisture from Pacific Tropical Storm Norma led to the severe flooding. (4th-6th) (The Weather Channel)

1983: Record heat occurred across parts of the Midwest and Plains ahead of a strong cold front. Record highs included: El Paso, TX: 101°, Roswell, NM: 100°-Tied, Chicago, IL: 95 °F -Tied. (Ref. Wilson Wx. History)

1986 - An unusually strong dust devil moved across the Flagstaff Pulliam Airport. The dust devil blew open the doors of the National Weather Service office scattering papers and bringing down a ceiling-mounted light fixture. (Storm Data)

1987 - Thunderstorms developing along a stationary front produced heavy rain across the Southern Atlantic Coast States. Up to eight inches was reported north of Charleston SC. Serious flooding was reported in Monks Corner SC. Seven cities in the northeastern U.S. reported record low temperatures for the date. Houlton ME dipped to 32 degrees. (The National Weather Summary) (Storm Data)

1988 - The western U.S. experienced another day of record heat. The afternoon high of 91 degrees at Stampede Pass WA established an all-time record for that location, and Los Angeles CA equalled their all-time record high with a reading of 110 degrees. A record high of 107 degrees at San Diego CA was their hottest reading in 25 years. Red Bluff CA was the hot spot in the nation with an afternoon reading of 118 degrees. (National Weather Summary)

1989 - Overnight thunderstorm rains of four and a half to seven inches drenched eastern Nebraska during the morning hours, pushing creeks out of their banks, and flooding fields, country roads and city streets. Totals ranged up to 6.97 inches south of Creston. It was also a soggy Labor Day for northern Florida. Jacksonville reported 6.82 inches of rain, and evening thunderstorms produced 2.75 inches of rain in one hour at Sandlewood. (Storm Data) (The National Weather Summary)

1996: Hurricane Fran reached peak strength of 120 mph 275 miles off the east coast of Florida. The Space Shuttle Atlantis had to be rolled back from its launch pad at Cape Canaveral as the storm threatened the east coast of Florida. The storm would make landfall the following evening on the North Carolina coast to become the most damaging hurricane of the 1996 Atlantic season. (Ref. AccWeather Weather History)

1998: Scottsbluff, NE equaled their warmest September temperature with a high of 102°. Other record highs included: Fort Smith, AR: 109°, Dallas, TX: 108°, Dallas (DFW), TX: 108°, Wichita Falls, TX: 108°, Oklahoma City, OK: 107°, Tulsa, OK: 107°, Waco, TX: 106° and Austin (Camp Mabry), TX: 101°. (Ref. Wilson Wx. History)

 

2000: Houston and College Station, Texas recorded their hottest day on record when highs reached 109° and 112° respectively. Houston has tied their record on August 27th, 2011. Other daily record highs included: Wichita Falls, TX: 111°, Waco, TX: 111°, Dallas, (DFW), TX: 111°, Austin, (Bergstrom), TX: 110°, Austin (Camp Mabry), TX: 110°, Dallas, TX: 110°, Victoria, TX: 110°, San Antonio, TX: 109°, Shreveport, LA: 108°, Corpus Christi, TX: 107 °F. 

2006: A slow moving low pressure system triggered scattered thunderstorms across northern Illinois during the afternoon. A series of slow moving storms moved into and sat over the east side of Rockford. As much as 5 to 10 inches of rain fell in a localized area, while less than 3/4 inch fell nearby at the airport. Damage was estimated around $20 million dollars. (Ref. Wilson Wx. History)

2007: Hurricane Felix came ashore in the pre-dawn hours as a Category 5 storm on the northeastern coast of Nicaragua. At the time of its landfall, the maximum sustained surface winds were approximately 160 mph. Felix killed at least 130 people along the coast, with damage in Nicaragua totaling $46.7 million. 

2008: The remnants of Hurricane Gustav brought heavy rains to southern Lower Michigan. Muskegon set a daily rainfall record of 3.25 inches and Grand Rapids sets a record with 2.82 inches. (Ref. Wilson Wx. History)

 

2011: The center of Tropical Storm Lee moved ashore around sunrise. However, it would be a while before Lee would weaken to a depression as it remained nearly stationary while the southern half of the circulation was over water where it could continue to derive additional energy from the warm ocean. Lee brought torrential rains to Louisiana, Mississippi, and Alabama.

 

2016: An EF1 tornado developed in the open country area north of Merna, Wyoming. The tornado caused tree damage along its 2.45-mile path. At its widest, the tornado produced sporadic tree damage approximately 300 yards across. The trees fell on some fence line but otherwise caused no property damage.

Picked up .60" here overnight.  Total for the month already at 1.55".  Looks like a drier pattern for the next 5-7 days.

Thankfully.

Just in case you were wondering about what the latest Drought Monitor looked like:

I think we're all GOOD !

[MANDA]

Just in case you were wondering what the status of the 2026 hurricane season is:

That is one quiet looking signal from Google Deep Mind going into mid month.

If we make it to September 11 with no hurricanes (seems likely) we will break the record for latest in the season with no hurricanes in the satellite era.

So much for cooler and less humid

 

Very uncomfortable
