Snow cover in the valleys?

Euro had some rogue spots in that range too, but a lot of 70+ over the interior.

Yeah. But I still think we'll pull off some 100-101s even with dews near 70. But if the GFS is right we probably start talking 103-105 in the torch spots. One other thing...in the KISS (keep it simple stupid) category. 850s are 22-23C midday. Lop a 15C on top of that and you have 37-38C (99-100F). If you want to go a little higher for some W component you've got 38-39C and you're in the 100-102F range. But I want to see 20kt from the WNW before I start going more wild with the downsloping.

Same location in CT...same time. 3k NAM vs GFS. The NAM is slightly more backed in the low levels with a lower mixed layer while the GFS is deeply mixed WNW flow up to H75.

Although I still wonder if models are somewhat overmixing. The 3k NAM is still 70+ dews all day. The GFS is trying to mix down 50s dews with 100F+ temps. I'm tossing that without having some kind of prefrontal trough like we had in 7/2011.

Today is a different beast from yesterday. When those westerlies start mixing down the temp is going to spike and the dews drop off.

The consoles sample variables at different time increments. So the dew probably changed from the time one console pinged it to when the other one did…just a guess. But I had 82° for a dew here as well. The Davis ones can become a little oversaturated with age, but we do get more pooled up moisture from evapotranspiration than wide open airports. But temp and dews actually change pretty rapidly with responsive equipment. Mercury thermometers have lag. These digital probes are almost instantaneous. That’s why ASOS uses running 5 minute averages to try to simulate the slower response of the mercury thermometers.

IZG 88F at 8a

I think he was referring to OXC. But still that’s an AWOS too. I don’t think we had anything over 78° at an ASOS?

I think that’s the first time I’ve ever seen 100° at LCI on MOS. Anyway, currently 69.8°. I see Tol is still 77°.

It’s go time.

A HADS site in North Springfield, VT hit 103F. https://mesowest.utah.edu/cgi-bin/droman/meso_base_dyn.cgi?stn=NOSV1&time=GMT

Today’s highs PBG with the 101°

Is that passive or aspirated? Same sensors?

They told us mid 60s dews at most. WTTTE

BTV mixing out now with more of a W component and up to 99F.

Good indication of what will happen tomorrow. Scorchah

Check out that temp jump/dew drop when the wind flipped W over 20mph. https://mesowest.utah.edu/cgi-bin/droman/meso_base_dyn.cgi?stn=KPBG&time=GMT

Mine has a 2F bias. Factor that in and it's pretty much spot on.
