I’ve found mine runs 1-2F warm. Like a 98F, I’m thinking 96-97F. My old SUV seemed spot on, like oddly spot on with obs. The MVL ASOS is like 100 feet off RT 100 so it was always easy to check when driving by.

High temps so far across Chester County have for the majority of stations been in the low to mid 90s. The hottest of course at KOQN Brandwine Airport at 98.6 degrees. The next warmest station just a few miles away was at the West Chester MADIS station at 95.9 degrees. Other area high temps so far West Grove 92.4 / East Nantmeal 92.1 / Avondale 93.2 / Atglen 93.6/ Glenmoore 93.9 and Chester Springs at 95.6

The pretend sea breeze might be slowly working here finally, I briefly touched 97 while spending the last 5 hours between 95 and 96, now I'm down to 93.

Upton raised my high from 98 to 102 tomorrow. I’m concerned for this AC

Same here. 74 upstairs, 76 downstairs.

See below regarding the thermo in my last car. The new Mazda seems to be about 3° too high.

The thermometer in my old Ford Fusion was surprisingly accurate. It would always match KMPV or my PWS. I could be up near the airport, look at my car thermo and then see what the obs were it was spot on.

It might stay in the low 70s on Friday. I think we'll welcome a cool cloudy day after this tremendous heat.

MDT with a quick plunge despite no clouds around and no real change in conditions ha.....

96/72. i’m impressed it got this hot here.

The dew point was 80 with a 102 temp. Not as extreme today.

My truck's thermo is so inaccurate, It runs 4-5°F to warm, I guess if you go with its bias you can guess close to actual during travel.

So far today across Chester County the majority of spots have seen high temperatures in the low to mid 90's. The big exception of course was at KOQN Brandwine Airport with a high so far of 98.6. The next hottest station was at the West Chester MADIS station at 95.9. Other Chester County highs so far - Avondale 93.2 / East Nantmeal 92.1 / West Grove 92.4 / Glenmoore 93.9 / Chester Springs 95.6 and KMQS 95.0

At least we are a little later in June so it's not as bad as earlier this month but still a continuation of that same theme...

Ha, that I-93 pavement. Though it matches with KCON at 97/74 in the 5-min data.

I agree. The nights have been very warm and muggy. The high temps have underachieved each day, although you and I discussed that as a likely scenario before the heatwave even started. Yesterday was surprisingly more oppressive than today. I expected today to be the worst.

100 at the house

Real and spectacular

This is one of my all time favorite wx days of all all time . One to recall fondly

Hi all... Just popping in with my current data. My official station has hit 99.3 degrees back at 3:13 and is now 98.6 with a dew point of 75.5 degrees and a heat index of 113 degrees. My backup station which is located about 15 feet away is currently 99.7 degrees after hitting a high of 100.2 and a current dew point of 75.7. This combination is producing a heat index of 114 degrees. The 100.2 now breaks last year's highest temp of 100.0 degrees by 0.2 degrees. It's horrible out!! I'll be back with final numbers this evening. Stay cool...

Sitting at 97 now in Lebanon with a HI of 111. Sultry baby .

In honor of this heat wave, decided to take an early look in the crystal ball and determined that June will end with an average temp of 74.0, good for ~1.4 AN and tied with 1923 for 12th warmest all-time. Book it.
