The MD mesonet shows a good correlation between temps and sail moisture.  The Salisbury area is dry and temps continue to run a couple of degrees warmer there.  That’s why I’m still skeptical of hitting 100 this week.

 

I noticed the same, it's definitely helping keep actual temps down. However it also makes the ET is sky high so the dew's are not mixing out as fast they normally would. Keeping the Heat indices high.

Need a westerly component at the surface, and some mixing, stat. if DCA is gonna make it to 100

I noticed Balt Harbor and PAX run several degrees warmer than everywhere else.  Are they off?

PAX always used to be slightly cooler than the rest of SoMD, or at least it seemed that way to me. The last two days have been odd.

It's 97 IMBY, but I'm about 30 mins north of PAX.

[wxmeddler]

Baltimore is understandable. I'm not sure what's going on with Pax River. We don't have any stations down there yet to verify. Could be micro-climate or sensor related.

Was just gonna mention about PAX. They've traditionally been pretty good. Starting to wonder what's up this year.

As to Balto...it's been off for many years, starting when the MD Science Center installed some solar PV panels next to the instrument. Added several degrees to every reading. After a while LWX removed them from their list for a few years. I (for one) will never reference that site again, winter or summer.

Maybe someone knows something about PAX. (There's significant knowledge hidden around AmWX; just need some patience usually)

Paging @csnavywx he might know?

FWIW, JFK is at 102

[H2O]

just hit 98.  Rooting for 2 more degrees

[yoda]

96 now at DCA... so got about 4 more hours to reach 100

[Terpeast]

97/74, HI 109 - 1 degree ahead of yesterday. 50/50 I reach 100

As of 1:00 pm today, Salisbury, Quantico, and Princess Anne are all running ahead to yesterday's temps. Definitely looking like a few 100° readings are possible.

Got one.  99

[katabatic]

Just hit 90 (yesterday's hi was 88.3) and with a DP of 72, it's a sauna even out here. First 90 of the year (2024 we had 3 days, never hit 90 in 2023).

Will be interesting to see where June 2025 finishes up. Plugging in the forecast values for the rest of the month would bring DMH up to 80.9 and BWI up to 76.3. This would be 2nd highest in the Downtown Baltimore station thread (since 1950) and 8th highest in the Baltimore/BWI station thread. It would be the 4th highest value at BWI (since 1950). For some reason, they thread hotter pre-1950 downtown rooftop values onto the much cooler BWI records rather than onto the Downtown Baltimore station thread.  All the while their media lapdogs bellyache about so-called tarmac heat at BWI despite overwhelming evidence that it's hotter downtown and closer to the Harbor. I don't get it.

Just made 90 here at 2:30 pm. Currently 90.1/73.8, makes heat index 99, which has me staying inside lol. 

[SomeguyfromTakomaPark]

Doing pull ups in my detached garage with no HVAC.  I imagine this is what it’s like doing hot yoga.  98/76 at the closest  reliable sensor.

DC could see a mean of 77.4 or 77.5F, which would be good for 10th highest in the threaded record. Not even going to bother looking at the IAD frost hollow numbers.

[MN Transplant]

DCA probably 98.  Reminder that 99 on the 5-min obs could be 98 or 99.  100 is 100.

I’m up to 97.5

[Eskimo Joe]

Salisbury mesonet site has hit 100°. Quantico not too far off at 98°. Berlin site doesn't look to get saved by a sea breeze today either.

Just for the hell of it, looks like 75.4F, which would be good for 4th place. But I bet those lows will come in below the NWS forecast with them saying it was colder at Dulles than Deep Creek Lake this morning. Lol.

probably 99F (with 4 straight 5-min obs of 98.6F / 37C).  We'll see!

Just hit 100…HI 113.   I am good now, this can end

Naw keep it going through Thursday at least. Enjoy summer. 34 and rain we can save for January.

[CAPE]

Looks like 96 will probably be the high here again.

[Mrs.J]

Just hit 100 here. Let’s go down from here the rest of the week. 

[WVclimo]

97° in the shade.  105° in the sun.

[George BM]

IAD up to 97F so far.

97/69
