A bunch of unmemorable heat days adding up to a memorable heat summer?

BDL 94/63 Weaker than Cesar Crespo

One night in Bangkok tonight?

There's a front going through on the 12z NAM, but it's pretty weak. More of a weak moisture boundary than any temp difference. Probably more near 90F temps for SNE Wed since there's little CAA and the drier W flow let's us heat up a bit more. Then it has the dews advecting right back in later on Wednesday. So yeah, maybe it ends up hanging up even more somewhere near the south coast.

Probably 96F as of now, but they'll be close. There's a hot pocket there with 95F at PYM and GHG too. Very meh elsewhere. BOS 91F and BDL 93/64 is so weak.

heh...HYA 94° TAN 92° is next highest for the METAR sites.

89/67 at 11a. WSW 10kt. Hot but we need to do better than that for 100°. Get that wind veered another 20-30° and crank it up.

HYA does seem to be 2-3F too warm based on all obs in the area. The 2nd highest in Barnstable is a 91F at a Sandiwch HADS site.

Something happened with MADIS around that time though. I'm not sure if the algorithms got changed or if another data network came online, but I do know there's been some issues since then. I'm not sure how well it's maintained anymore.

I wonder if something happened to coastal obs last September on MADIS. PWM has a similar drift. I think there's some MADIS error there.

HYA 93

I'm at work being very productive. Nice ob from CON on July 5, 1990 before a front. 85F at 2am. CON,1990-07-05 06:00,KCON 050600Z 24009KT 5SM SCT120 OVC250 29/22 A2955 RMK OCNL DSNT LTG SW/ SLP004 8/078 T02940217 403280194 57005

And it looks like PWM actually has done an 80+ night before. That torch night going from the heat/dews on 7/21 to the dry 100s on 7/22.

September of 2008...I don't remember that one. Ha. Looks like it was prefrontal. M/U 70s after midnight and low 50s by the afternoon.

Better mixing as the inflow picked up? idk...I haven't looked at much yet. Looks like SLK has done 75F after midnight before, but it's pretty rare. Looks like it happened at 4am as well once. I'll have to dig for the year in the raw data.

No ACs and no TP. Difficult times.

I think the convection helped that. The mixing usually picks up ahead of the convection like that. All of NH was down into the U60s or L70s.

Hasn't happened at CON or BDL since the 1940s either.

Heh...looks like it's a first for that pre-sunrise period. I thought maybe there was a torch in there where maybe they stayed at 80F all night and ended up with a late day sub 80F thanks to a front or storm, but looks like nada.

How many times do we approach 100F without haze?

lol I missed that this morning. Even PSM and BOS are down into the mid 70s with similar mixing. PSM has some clouds too. Downslope off of lavarock’s lawn maybe? Did they put down a nice layer of black mulch per DIT’s recommendation?

Maybe, but another station may have come online nearby too. MADIS itself isn’t perfect either, but like you said, it has caught some drift in the past. Had PWM stood out a bit to you before seeing that graph?

70.7° overcast Looks like there’s some convection in N NH and N VT that’s trying to drop SE. it probably won’t make it down here, but I wonder if that messes up the heating during the morning.

75/66 Amazing sunset tonight

Probably a combo of out of state travel, opening back up, and the warmth keeping everyone enclosed in AC.
