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

Sounds a bit...cranky?

84.8/77

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

Almost the hottest heat index on record (since 1948) at CON at 4pm

92.4/75

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.

Heat indices get exponentially wonky when the dews get high. There's going to be higher dews over the vegetative/wet areas though. The Davis sensors may be a little high, but the dews definitely pool from evapotranspiration on these dead air heat days. My dew hit 82F earlier...but I usually only post here the lowest dew I record in the previous 15 mins or so. Like my dew is 78F right now, but it recorded 75F twice in the last 15 mins so I'll call it 91/75. Jives more with the ASOS sites.

Lay on a hard floor flat on your wet back and make suctiony fart noises.

I was thinking that. Like 7/21 vs 7/22 in 2011
