August 5th-8th 90(s) Degree Day Obs. First Time Ever PHL Had Four Consecutive 92 Degree High Days.

[Rainshadow]

It should start today for most lower elevation spots.  Dew Points should get slightly more tolerable this afternoon, not so much after that til the weakening cold frontal passage.

WAG PHL 91F or 92F today for a high.

My daily rant of you outright  with 2M surface temp predictions during summer GFS.  

Worst part about this non stop nonsense is that it has infected MOS or MOS is not smart enough to smell a rat (which it should).   I was clicking on the EMC site and it looks like the farther east in the conus and/or the larger the city, the more egregious this warm bias is.  Congrats Boston, I think you win this contest too.  I don't know how dry Boston has been recently, but the recent wetness (OP EC is about 5F lower with max temps for PHL, but they tend to be about 2F too much in the cool direction) is given 0.0000003 second consideration by the GFS.  The EC obviously has a better grasp of soil moisture content as it never bit on the let's have a bunch of 100s (heck 108 in DCA) party the GFS was throwing in early July and it was nearly as hot as the GFS in mid July when antecedent conditions became drier.

Have to wait til 8 pm to see if something higher snuck in, but looks like PHL high was 92F.  We had the same high in Mount Laurel, our first August 90 degree max day and our first 90 degree max day since July 17th.

90 IMBY.

89F high

This humidity is unrelenting.  

I have a small handful of days off that I want to use as maintenance/stay at home days for the rest of the year; I feel like they are wasted if I'm just going to sit at home in the A/C all day.  Trying to save them up for fall.

We are headed to OBX Labor Day week.   Just hoping the tropics behave while we are there.

BTW BOS max temp was 87F.

Going to WAG a high of 93F for PHL today.  Going by the 11C+925mb 15z result from yesterday off the GFS PHL's high would be 92F again.

We are in marginal risk on CFP Wednesday:

I was downstairs around 12:45 PM and was kind of surprised to see it raining here in Green Hills, PA.

91 IMBY.

Welp 11C+15z 925MB would give PHL a hat trick 92F for a high today.  Wednesday has to potential to be hotter because of thermal conditions, but not sure if clouds will get in the way.

A pair of marginal risk days coming:

As for the pair of 95(s) at PNE, I know there exists differences in opinion about the Gladstone qc methodology.  Be it as it may, PHL bias has been neutral the past week, while PNE bias is nearly +2F with max temps.  The bias is still there at PNE if one expands the data range to a month, while PHL has been averaging a cool bias of about 0.75 of a degree.

Well, it could be worse. From Mt. Holly:

84/77 here in WW crest. Headed to the beach with plenty of liquids to stay hydrated 😅🍺

[chescowx]

So far this week of course no 90 degree readings here in NW Chesco - I do see PHL likely to hit their 19th such day of the year and 3rd?? in a row. While here in Chesco no 90 degree days in over a month with the last one recorded during our one and only heat wave of the season on July 3rd. For the year so far only 4 days above 90 in these tundra areas!

Looks like triple 91's IMBY for the past 3 days. Some of the worst feeling 91's I can ever remember.

86/78 here in WW Crest. Thanks baby Jesus for the seabreeze. It is gross out there.

Looks like storms are popping to the west.

Looks like it is going to be a hat trick 92F for PHL and also a 92F for a max temp here in Mount Laurel.
