I really don't know what the NWS is thinking by putting 104 and 105 into the zones. You don't forecast historic heat 4-5 days out, especially when the only guidance giving those types of numbers are models that have known boundary layer issues.

We found Ineedsnow and Kooky Kenny

I’m still feeling mostly 98-100 in the hot spots right now…not buying the 2m 103-105 stuff with 850s of only 22-23C. I’m sure EWR will drop a 104° one day over the tarmac though. Just imagine all of those sweathogs in DC later next week for the 250th. No thanks.

Going to fall short of triple digits but we should string together 5+ 90 degree days, with near daily storm chances. 16 of the last 17 days have been BN. A classic summer heatwave was bound to happen.

Even the 88 figure in Downtown Baltimore seems excessive, but it's remotely plausible if the observation site is in the middle of the urban heat island, surrounded for miles on all sides by asphalt and brick buildings, with absolutely no green space.

In other words days and days of shirtlessness (perhaps down to short shorts?) with several packages of hard mikes and dude wipes on standby. Lfg baby!

Very strong coupling now (ocean-atmosphere/Bjerknes feedback) showing up….the ERWs are constructively interfering with El Niño. Also, classic Nino standing wave convection/-OLR

Try to make today a good day.

Yeah euro op is still pretty warm. Lots of 15-20C in the extended. ACATT squealing for help.

It’s like Ineedsnow drew that map

Makes you really miss years like 1996 with 77”-92” of snow and only 1-5 days reaching 90° on parts of Long Island.

After the 4th we cool off but still summery. It’s here baby.

Looks a lot worse than typical. Long lasting with many records broken.

Why couldn't today have been yesterday's weather? I needed a morale booster so bad, and instead, I got the opposite.

Hard L

That would be impressive. I can't recall a reading at DCA of 105, but admittedly I don't track summer heat . Edit:: Google tells me this happened in 2012. I was here and it was super hot, just don't remember the 105 reading

Looks like a typical New England heat wave. We embrace

LWX going 105 in the zones at DCA for Friday .WEDNESDAY...Sunny, hot with highs in the upper 90s. Heat index values up to 110. .WEDNESDAY NIGHT...Mostly clear. Lows in the upper 70s. .THURSDAY...Sunny, hot with highs 100 to 105. Heat index values up to 110. .THURSDAY NIGHT...Mostly clear. Lows around 80. .FRIDAY...Sunny with a chance of showers and thunderstorms. Hot with highs around 105. Chance of rain 30 percent. .FRIDAY NIGHT...Partly cloudy. Lows in the upper 70s. .INDEPENDENCE DAY...Mostly sunny with a chance of showers and thunderstorms. Hot with highs around 100. Chance of rain 40 percent.

.CLIMATE... Triple digit max temps are forecast in the Lower Susq Valley (LSV) on Thursday and Friday bookended by upper 90s Wednesday and Saturday. The last time Harrisburg observed consecutive days with maxT greater than or equal to 100F was back in 2011 on July 21-22. The record number of consecutive days with maxT >= 100F is 3 and has occurred 5 times: (all in the month of July) 1999-07-16 to 1999-07-18 1999-07-04 to 1999-07-06 1991-07-19 to 1991-07-21 1966-07-02 to 1966-07-04 1936-07-09 to 1936-07-11 The last time Harrisburg hit the century mark was July 16th in 2024. Prior to that, it was July 19th in 2020. Harrisburg averages 1 day annually with a maxT >100F. The most number of days observed in a year is 6 in 1999.

And in 6 months or so our heating systems will be getting a workout.

Like the "29 inches of snow that fell at BWI in 2016. Bogus. I measured 21" at BWI. The biggest official snowstorm is Bogus. Feb 2010 was the GOAT.

Disgusting
