850 temps of 22-23c this afternoon (23 C next frame)

You love looking at the pretty colors. :thumbsup:

Simple text sounding search shows

94 today and 97-99 tomorrow, areawide.

850 temps are warmer today then tomorrow, according to NAM. 22 today and 20 tomorrow.

That looks much cooler than previous forecasts, especially NE of NYC

I wouldn't even go by what the surface temps are showing on those maps. I'd go more by 850 temps. If they indeed will be up near 22-23, then upper 90's is almost a guaranteed certainty and 100+ is definitely in the cards for some of the warmer locations.

Yeah, I'm not sure Southern Westchester is going to hit the forecast high of 96F. It's 78.7F here so we've got a chance as the temperature has been rising pretty rapidly, but I wouldn't say mid-upper 90s is a lock.

Dewpoints are pretty high though, 69F here. Very muggy out but luckily I'm in an AC workplace.

Doesn't that map show 850s of 18-20C, not 22-23C? I don't see the 21-22C 850s that Earthlight mentions on the above map.

I agree that 850s of 23C should produce widespread upper 90s/low 100s, but it depends a lot on cloud cover. Humidity is also pretty high so that may reduce the heat a bit. It's hard to get to 100F here in Dobbs Ferry without drying/compressional warming on a W/NW downsloping wind.

I didn't look too closely at his map. I just assumed John had the correct numbers, and I believe he does, as shown below... Yes, cloud cover will play a role, but if you read the morning NWS discussions, they expect lower dewpoints to be able to mix down today so the dew point should probably drop a bit during the day.
