A somewhat cooler than normal August is concluding. New York City had a mean temperature of 75.0°, which was 0.9° below normal.

After an unseasonably chilly night, tomorrow will be fair and cool. The Labor Day weekend will start cool but turn noticeably warmer.

The ECMWF weeklies suggest that the September 4-18 period could see temperatures average above to much above normal across the region. Parts of the region could see high temperatures peak at or above 90° on one or more days.

The ENSO Region 1+2 anomaly was +3.1°C and the Region 3.4 anomaly was +1.5°C for the week centered around August 23. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +3.27°C and the ENSO Region 3.4 anomaly has averaged +1.23°C. El Niño conditions will likely continue to strengthen into the fall with the current East-based event transitioning to a basinwide El Niño for the upcoming winter.

The SOI was -9.83 today.

The preliminary Arctic Oscillation (AO) was -0.007 today.

On August 29 the MJO was unavailable. The August 28-adjusted amplitude was 0.986(RMM).

Yes, It was an uncommon event. Predominant patterns were stuck. Parts of the South roasted with their highest monthly and seasonal temperatures on record. Some of the records were annihilated. It was unseasonably cool up here.

Got down to 51 this morning, impressive. 

[steve392]

55 degree's this morning in paramus, nj.  Gorgeous out.  First time since spring i could see my breath outside.  Almost hoodie weather but its still the false fall, second summer is coming.

[SACRUS]

64 / 52 down from 52 here.  NNE flow coming around to the N warming to near / low 80s.   Sat (9/2) - the week ridge builds flow to the NW heating it up 90s Sun - Wed or Thu.  Ghost of Idalia may back enough to bring onshore flow especially to the coast perhaps even clouds GFS more west / Euro keeps east.   Peak of this late heat mon - wed 850 MB temps >16c, / >18c.  Strongest heat may stay just a shade west.  Thu / Fri (9/8) watch for any onshore.   

Ridge into the SW by the 10 but heights look to come back up east towards mid month. Overall warm and mainly dry outside ULL cutting of beneath the ridge or tropical energy.

Historical:

 

1859: One of the largest geomagnetic storms on record occurred. 

 

1862: The Battle of Ox Hill (or Chantilly) is also known as the only major Civil War battle to have been fought during a storm. “A severe thunderstorm erupted, resulting in limited visibility and an increased dependence on the bayonet, as the rain soaked the ammunition of the infantry and made it useless.” From Taylor, Paul. He Hath Loosed the Fateful Lightning: The Battle of Ox Hill (Chantilly),

 

1869: Cleveland Abbe issued the first Weather Bulletin for the city of Cincinnati, Ohio. It contained a few observations telegraphed from distant observers and the “probabilities” for the next day. The bulletin was written by hand.

1894 - A forest fire driven by high winds burned down the town of Hinkley, MN, killing 418 persons. (David Ludlum)

 

1894: The Great Hinckley Fire, which burned an area of at least 200,000 acres or perhaps more than 250,000 acres including the town of Hinckley, Minnesota occurred on this day. The official death count was 418 though the actual number of fatalities was likely higher. 

1897 - Hailstone drifts six feet deep were reported in Washington County, IA. (The Weather Channel)

1914 - The town of Bloomington, MI, was deluged with 9.78 inches of rain in 24 hours to establish a state record. (31st-1st) (The Weather Channel)

 

1928: Leslie Gray from the Weather Bureau in San Franciso was the first weather forecaster to be deployed to a wildfire.

 

1952: A cold front brought damaging winds to Fort Worth, Texas, including the Carswell Air Force Base where thirty-five B-36 planes received damage. The anemometer indicated 90 mph winds before being smashed by debris.

1955 - The temperature at Los Angeles, CA, soared to an all-time high of 110 degrees during an eight day string of 100 degree weather. (David Ludlum)

 

1961: An F4 tornado traveled through parts of Butler and Bremer Counties in Iowa. Unfortunately, there is limited information in the Storm Data entry about this event.  Per Thomas Grazulis in Significant Tornadoes, the tornado began NW of Dumont and ended NE of Horton.  Several farms along the path were "leveled".  It was reported at one farm that fruit jars were "sucked out of the basement" after the house was swept away. There were 7 injuries reported with this event and zero fatalities. 

1979 - A home in Centerville TN was hit by lightning and totally destroyed. It marked the third time that the house had been hit by lightning since being built in 1970. (The Weather Channel)

1987 - Cool Canadian air invaded the Midwest. Six cities reported record low temperatures for the date, including Indianapolis IN with a reading of 44 degrees. Hot weather continued in the northwestern U.S. Five cities reported record high temperatures for the date, including Hanover WA, where the mercury soared to 106 degrees. (The National Weather Summary)

1988 - Thunderstorms produced heavy rain in the Upper Mississippi Valley. Ely, MN, was drenched with three inches of rain in two hours, and pelted with one inch hail. The heavy rain flooded streets and basements, and the high water pressure which resulted blew the covers off manholes. (The National Weather Summary)(Storm Data)

1989 - Thunderstorms developing ahead of a cold front produced severe weather in Oklahoma during the late afternoon and evening hours. Thunderstorms produced hail two inches in diameter west of Arapahoe, and wind gusts to 70 mph at Luther and south of Harrah. Early morning thunderstorms over Indiana drenched Kokomo with five to eight inches of rain, and spawned a tornado which injured three persons at Bruce Lake. (The National Weather Summary) (Storm Data)

 

2017: The temperature at Downtown San Fransico reached 106° setting their all-time record high. The previous record was 103° on June 14th, 2000.

Apparently some people are stuck on this idea that summer was an ice age.  I don't get it.
