@ 4pm

ABE: 100

RDG: 102

PTW: 99

Tombo, ya beat me!

100 at abe 4pm obs

102 rdg

99 ptw

Did ABE hit 100 last summer?

[LMolineuxLM1]

I know its my car and all, but it said 102 when i got onto the Blue Route once onto the blue route it leveled off at 100 for the whole drive down it, then once i had to stop at Baltimore Pike to get onto it, it spiked back to 102, but driving down local roads to get home the temp dropped to 95 then once closer to home where there is like no tree's for shade it spike back up to 102.

[NortheastPAWx]

high at phl so far is 97.

KAVP @ 96...

[Parsley]

100.0 here @ 4pm.

Max. still 100.4 @ 3:20pm

Definetely hasn't been full sun either here with that streak of Cu on the satellite sitting overhead much of the afternoon here. No wonder RDG and ABE are roasting they are Cu-free.

[famartin]

Did ABE hit 100 last summer?

101 on 7/6.

101 on 7/6.

thank you, sir.

I'm pretty sure KPTW will hit it. If KPHL doesn't hit 100 tomorrow, though, my prediction will be slightly high. The only good thing about hot summers is that decent winters often follow, right?

[Eskimo Joe]

Doubtful KPHL spiks 3 degrees by 5pm. Hoping that it doesn't get too cool this evening.

Doubt it as well.....atleast the 12z NAM still shows the 100+ heat for many areas tomorrow including PHL.

Has to be a more westerly wind tomorrow and less cloudiness or Philly won't do it. I'm surprised PNE didn't hit 100.

Yeah its strange seeing the mid-90s straddling the west side of I-95 from Chester, PA to about Trenton, NJ. Could the Delaware River really have an infuence, or maybe just the recent rains out that way.

104 here for the high today

97.2/76 HX of 114

high was 98.3 at 3:54

HX max was 118 at 2:23

[tombo82685]

phl topped off at 98 today

[tombo82685]

i think they should be good. I think the morning fog didn't help today at all. Tomorrow morning should be fog free and a higher starting temp. Forecast also shows a west wind.

[Rtd208]

High of 98 for the day, currently 97.

[ChescoWx]

Today in the NW Philly Burbs

High 93.5

Low 72.9

High Heat index 114.6

Tomorrow the Wxsim has a high of 99....the highest temp I have ever recorded here is 95.7 on July 6, 2010 could be in danger tomorrow!!

The all-time record high for tomorrow here in my Chesco database is 100 set way back in 1899.

[greg ralls]

phl topped off at 98 today

Kathy Orr just said Philly topped out at 99 degrees today, but I believe you over her.

thats what i thought the one ob had 98.6 at 4:33 this afternoon on wunderground, but their climo page has 98 for the day

I could have swore I saw 99 on the Utah mesonet page.

the climo page has 98...but the one remark by the asos? has 98.6 at 4:33

[famartin]

Here's the deal on the Philly 98 vs. 99 issue:

The one ob showing "99" is this one:

SPECI KPHL 212033Z 22015G20KT 10SM FEW055 37/22 A2977 RMK AO2 $

Note that special obs between the hourlies do NOT report temperature to the nearest degree Fahrenheit. They only report to the nearest degree Celsius. In this case, 37 degrees Celsius. There are two Fahrenheit temperatures which round to 37 degrees Celsius, 98 (36.7 Celsius) and 99 (37.2 Celsius). Since ASOS is continuously recording (but not reporting) in Fahrenheit, the temperature at the time of the 37C reading has to be either 36.7 or 37.2. However, a direct conversion of 37C is 98.6 degrees Fahrenheit.

In other words, its rounding error from converting the ASOS measurement (made in Fahrenheit) into Celsius for data transmission, and then converting it back to Fahrenheit.

Bottom line, the correct high today thru 5PM is 98 degrees.

Ray, i think you're a human ASOS

Ray, i think you're a human ASOS

As a "climate geek" I have made it a goal to know just about as much as I can about our primary observing system, so I'll take that as a compliment

[PAPPG]

High temp of 99 , HI of 112. HI is a 2 yr record here.

Amazing is the difference between being outside versus AC inside in this soup.

Not sure how people made it yrs past!

[mattinpa]

I thought today felt worse than last year's heat. Anyone agree? It was a complete sauna out there. Hard to be out even.

[Parsley]

Eastern PA airport stations that hit a 100 or more today per 8pm climo release:

ABE-100

RDG-102

PTW-100

LNS-100

Yup, higher dewpoints compared to last year. Lets see what tomorrow has instore. PTW hit 104 last year....not sure it gets that high, but there is a chance.
