The ECMWF does tend to overdo these scenarios this time of year, but it is certainly an interesting solution over the North Atlantic from D8 - D10.

 

That is interesting. Not likely to verify IMO though.

 

The Euro also backed away on any sort of moderation after the cool shot this weekend. In fact, after 120 hours, 850 mb temperatures never get above 10 C anywhere in the area, and are below 5 C for a large portion of the D5-D10 timeframe.

 

Still looks like 90+ is possible Wednesday, though the Euro backed away on the widespread 90+ it had yesterday on the 2 meter temperature maps.

ECM cuts off a low while other guidance and the ecm ensebles rebuild the ridge by the 17th.  We'll see if the euro loses it or other guidance latches on.

The 18z GFS looks like it also wants to try and dig another trough into the east after the first trough later this week. Should be interesting if the second trough continues to trend more amplified or not.

Way too early to say but 2007 is similar enso currently.  I dont think we'll see an Oct tha t anomalously warm for a while.

I like 1964 and 1981 as analogs for the fall...the first three weeks of October 1964 were well below average...then an above average regime set in until late November...October 1981 was even colder...October will be a test for these analogs...

Bone chilling...

1981 seems like a better analog ENSO wise, but we'll see. ENSO region 3.4 saw a jump from -0.25C to +0.04 over the past week. Could be a temporary bounce.

The gfs continues with the cool shot, coolest run yet for some, and it struggles to moderate as much afterward.

Still looks like some 90s for Wednesday unlikely for Tuesday and Thursday so it'll be a one day kind of deal. I've said before that we would be done with 90s (could be wrong), ill say it again just because of climo and the fact that I don't see a massive warmup after the midweek late heat blast.

Highs may not get out of the mid 60s for either Friday or especially Saturday and lows are likely to be in the 40s away from the coast and immediate urban locales.

50.6 here last night, great radiational cooling conditions for nassau.

Any real weenies out there may be interested to note that a distinct land breeze developed along the north shore of long island last night, keep areas within 1-2 miles of the sound significantly warmer than areas just inland. A quick review of PWS all the way out notes this very clearly. Most evident is northport yaght club PWS, notes a distrinct wind shift to the S when temp plummets, and then after sunrise switches back to the north, unsurprisingly, its low was 8-10 degrees warmer than locations just a few miles inland.

This extended west into nassau as well, where i bottomed out about 50, while Roslyn, right on the water, bottomed out at only 57 and the wind was blowing from the South all night, while my winds were dead calm all night long allowing for radiational cooling. At this time of year, the sound is still near 70, and with land temps dropping into the 50's, the strong temp gradient creates a persistent land breeze preventing areas along the immediate coast from radiating well.

Really cool. Thanks for sharing.

there's an outside chance for the warmer spots to achieve a heat wave if we mix enough tomorrow and clouds/convection hold off til afternoon on thursday.  and the euro backed off significantly on the re-establishment of the eastern trof after it moves out sunday

I agree for places like EWR, New Brunswick maybe even TTN (which seems to have been running cool compared to surrounding areas of late).  Thu could be issues with clouds

Wed 9/11 record highs look safe.   But I think with enough sunshine we could be looing at mid 90s.

 

NYC:  99 (1983)

LGA: 96 (1983)

JFK:  96 (1983)

EWR: 99 (1983)

 

 

One last hurrah for the pools or do we exceed 85+ again mid/late next week? I think we'll probably be back into the 80s by D 10 but we'll probably be done with 90s after Wednesday. Climo is against us at this point though we've seen hot shots to 90F for another few weeks.
