There's no heat dome for the foreseeable future now at least not on the east. Maybe not until next season. It looks as though our area maybe have a few days in the mid-upper 80s but at least at this point, I'm not seeing any more 90s in NYC. I suppose there's an outside chance in the second or third week of September but the maps appear to be trending steadily cooler. We'll see.

i will drink to that.

53 here this morning.

[FPizz]

50 this morning, was hoping to get into the 40s.

46° at FOK with the strong radiational cooling.

[SACRUS]

66 / 52 after a low of 50.  Cool retreats warm spot back to or near 80.  Warmer the next 3 days peaking Sun with the wamer spots touching 90.  Cut off undercuts the norther ridge later Mon - Wed with onshore flow keeping heat west but overall warmer airmass keeps in near normal before burst of heat to close the month.  Trough followed by ridging - overall warmer (above normal) from labor day onwards.  Any heat is brief.  Tropicals may reactivate on the Day 7-10 period, otherwise a drier pattern lingers into labor day.

Overall coolest departures since May 12th.

Next week looks mainly dry, mon / tue could see come pm storms as the cutoff UL moves SE offhsore of the area

Core ridge to the north, onshore keeps heat west at bay but near normal between brief  pushes of  hotter air coming east.

This is a continuation of the theme needing record blocking and rainfall to get a briefly cooler pattern. Looks like we go back to the usual warmer near the coast and cooler over the Midwest later August into early September. So more 90° potential for the regular warm spots in NJ. 
 

Record blocking north of Hudson Bay with cool down.

 

More 90° heat potential from ensembles for the usual warm spots in NJ

 

 

Midwest cool and warmer Northeast as we head into September

@winterwarlock where did this rain come from? 

no rain and going to enjoy this bone dry weather and watch temps creep to 90 over the next few days

[winterwarlock]

phew

A stunning 73 / 53 and blue skies

[Stormlover74]

And just like that it's cloudy

[winterwx21]

Yeah pretty cloudy right now, but another very comfortable day with the low humidity. About the last of the cool weather for awhile as we go into a warm pattern in the coming days. No more brutal heat, but lots of 85 to 90 degree days over the next couple weeks. 

[Wxoutlooksblog]

There are a couple of 90 days on the EC-AIFS. We'll see.

Tomorrow will become somewhat milder with temperatures topping out in the upper 70s and lower 80s across the region. A warmer pattern will develop during the weekend. Temperatures could briefly reach much above normal levels in the closing days of August.

Out West, cities such as Flagstaff, Las Vegas, and Phoenix remain on track for their hottest summer on record. Del Rio is in the midst of its record third extreme heat event (Clarke et al., 2014 framework) of the year. High temperature records fell in parts of Texas. Highs included:

Abilene: 111° (old record: 104°, 1917)
Austin: 107° (old record: 105°, 1917, 1925 and 2011)
Brownsville: 99° (tied record set in 1883 and tied in 2018)
Corpus Christi: 101° (tied record set in 1997 and tied in 2009 and 2010)
Del Rio: 113° (old record: 104°, 1911, 1991 and 1997) ***New August record***
San Angelo: 112° (old record: 105°, 1910, 1923 and 2010) ***New August record***
San Antonio: 106° (old record: 103°, 1948)

Abilene, Del Rio, and San Angelo recorded their latest cases of two consecutive 110° or hotter days. Abilene saw its first ever case of two consecutive 111° days.

The ENSO Region 1+2 anomaly was 0.0°C and the Region 3.4 anomaly was -0.1°C for the week centered around August 14. 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 +0.05°C. Neutral ENSO conditions will likely evolve into a La Niña event during the fall.

The SOI was +18.57 yesterday.

The preliminary Arctic Oscillation (AO) was +2.255 today.

Based on sensitivity analysis applied to the latest guidance, there is an implied 71% probability that New York City will have a cooler than normal August (1991-2020 normal). August will likely finish with a mean temperature near 75.3° (0.8° below normal).

Historical:

 

1816 - The growing season for corn was cut short as damaging frosts were reported from North Carolina to interior New England. (David Ludlum)

1923 - The temperature at Anchorage, AK, reached 82 degrees, a record for August for the location which was later tied on the 2nd in 1978. (The Weather Channel)

1987 - A cold front lowered temperatures 20 to 40 degrees across the north central U.S., and produced severe thunderstorms in Ohio and Lower Michigan. An early morning thunderstorm near Sydney MI produced high winds which spun a car around 180 degrees. (The National Weather Summary) (Storm Data)

1988 - Afternoon highs of 88 degrees at Astoria, OR, and 104 degrees at Medford, OR, were records for the date, and the number of daily record highs across the nation since the first of June topped the 2000 mark. (The National Weather Summary)

1989 - Evening thunderstorms in the central U.S. produced golf ball size hail at May City IA, and wind gusts to 66 mph at Balltown IA. Lightning struck a barn in Fayette County IA killing 750 hogs. Evening thunderstorms in Montana produced wind gusts to 70 mph at Havre. (The National Weather Summary) (Storm Data)

1992 - Hurricane Andrew makes landfall in Southern Florida as a Category 5 storm with wind guests estimated in excess of 175 m.p.h. Estimated damages exceeded $20 billion, more than 60 people were killed and approximately 2 million people were evacuated from their homes. (University of Illinois WW2010)

 

1994: Hurricane John, about 345 miles south of Hilo, Hawaii had winds of 175 mph and pressure at 920 millibars or 27.17 inches of mercury, making it one of the strongest hurricanes ever in the Central Pacific. The 31-day existence made John the longest-lasting tropical cyclone recorded in both the Pacific Ocean and worldwide, surpassing both Hurricane Tina's previous record in the Pacific of 24 days in the 1992 season and the 1899 San Ciriaco hurricane's previous world record of 28 days in the 1899 Atlantic season. John was also the farthest-traveling tropical cyclone in both Pacific Ocean and worldwide, with distance traveled of 7,165 miles, out-distancing previous record holders Hurricane Fico in the Pacific of 4,700 miles in the 1978 season and Hurricane Faith worldwide of 6,850 miles in the 1966 Atlantic season.

The weather has been perfect the last two days, the first two days were too cold and windy which aggravated my allergies.

Chris, did this last event remind you of Nemo in some ways?  Same areas got the historic totals in both storms (the snowfall max spot on Long Island!)  I don't mind getting off easy with only 2-3 inches of rain this time, big time flooding is one type of extreme event I never want to see.
