IAD as always the laggard, still 97

Cobble Hill Brooklyn, 101. As always ….

Looks like the HRRR is already busting for today

yeah but what's the depth of those temperatures?

100/72/110 at BWI

wow just noticed that. Cape Cod Bay buoy up to 77.2 and ACK 75. impressive though it's shallow

Backyard Davis in tune with ASH airport 95/65

Wow 100 air temp all the way out there?

Watching the yard burn up in real time. I may wanna hit up @EastCoast NPZ for recommendations on some good cacti to plant around here

I know the response will be, “Well, that’s just Cleveland.” But this has not been isolated to Cleveland at all. The magnitude looks comparable across much of the region. For example, I saw someone from Detroit downplaying the event. Barring enough thunderstorms or rain-cooled air to meaningfully alter today’s outcome, Detroit looks poised for its second-warmest four-day stretch since 1953, behind only a comparable period in 2011. And that 1953 benchmark was observed at City Airport. While there is a substantial data gap there, this stretch appears likely to be the warmest at City Airport since 1936—warmer than both 1953 and 2011. I get that Cleveland and Detroit have had hotter individual days and worse heat waves before. But this strikes me as a legitimately high-end regional heat and humidity event, especially for early July. I am honestly surprised by how little appreciation it seems to be getting.

100/75 heat index 114 for the third straight day

Here comes the EPAC TC parade…..

Ryan Maue @RyanWeather · 18h Watching with some concern about the "mother of all heat domes" across the Western U.S. in 10-12 days ... triggered by Super Typhoon Bavi. This would be unprecedented ridge strength at 6045 meters (500 mb height) Nobody has seen this before Ryan Maue @RyanWeather · 3h "Mega Typhoon Bavi" Super Typhoon Bavi has an opportunity in the coming 4-5 days to set the "world record" for the most intense tropical cyclone observed, since Tip in 1979. ECMWF HRES (00z) at 872 mb --> upper echelon of Earth's maximum potential intensity.

I'm at 98 for my high so far (also current), with dp 80.

It has been a ho hummer heat wave up here at Pen Mar. 96 right now which is the highest of the season. BUT I have seen 103 in Emmitsburg, 104 in Gettysburg PA and 105 in Lewisberry PA so some low landers, albeit it North of many here, getting a once in a decade or more heat wave today.

College Park (CGS) hits 100°, Andrews (ADW) hits 101°.

Am I the only one who has been impressed by this heat wave? It feels like it has been oddly downplayed. Assuming Cleveland Hopkins Airport reaches the forecast high of 95°F today, and the temperature does not drop below the current daily low, the June 30–July 3 period would average 86.3°F. It has already reached 94°F, so not far under that forecast value. That would be hotter than every four-day stretch in the Cleveland record except the periods ending July 11, 12, 13, and 14, 1936, and September 3, 1953. It would also make this Cleveland’s first three-day stretch of 95°F+ since 1988. And it has not just been one hot afternoon. On June 30, Cleveland reached 93°F, the second-warmest reading for the date. The low of 78°F set a daily record and was the third-warmest June low on record. The 85.5°F daily mean was also a record. Then came July 1: a record high of 97°F, Cleveland’s hottest day since July 17, 2012. The 87.0°F daily mean set a record and was only 2°F below the all-time warmest daily mean on record. July 2 reached 96°F, the second-warmest high for the date and just 1°F below the daily record. The 86.0°F mean was likewise second warmest for the date, and the daily records for that date are from 1872 when the weather station had a warm-biased window exposure. Today, July 3, the low has only fallen to 78°F thus far, yet another daily record, and just 3°F shy of Cleveland’s all-time warmest low. Cleveland had already reached 94°F by 2 PM local time, and a forecast high of 95°F would yield an 86.5°F daily mean, another record. The humidity has been just as remarkable. IEM hourly data, extending back to 1931, show four June hourly heat-index records set or tied on June 30, along with six June hourly dewpoint records. At least seven July hourly dewpoint records have already been set or tied as well. Cleveland also observed a dewpoint of 80°F or higher—only the fourth day with such a reading in the IEM hourly record since 1931. Maybe this is not the most historic heat wave ever in every respect, but several daily records, near-monthly records, extraordinary dewpoints, a rare 80°F dewpoint, and very little nighttime relief seems pretty impressive to me. If we were looking at a four-day cold spell that ranked behind only a 1936 cold wave and one 1953 period, with several daily records, near-monthly records, record-level hourly departures, this forum would be hyping it nonstop.

RDU stalled around 97 F for a bit but wondering what is going on there between hours.

95 degrees 15 mins ago, pouring rain in a storm, down to 83!!! Picked up a quick quarter inch so far. Florida like weather here in the ATL area the last month. Strange.

He beer.

We’re surging temps now, just crossed 103. My goodness this weather sucks
