The upcoming east coast heatwave and the recent western snowfalls is a canonical la nina feature. Yet another sign we are not yet being influenced by + enso.

3+" of rain around the Two Harbors area yesterday. A general 2-4" in the wider area. More chances for stms mainly Wed-Thurs.

Woot, we got our Extreme Heat Wave Thursday/Friday

I saw that. NBM is heavily used by NWS per AFD omission. Is there a verification page or ?

I think the Heat Advisory is just for Wed

Seems to be cooking about 4-5 degrees too warm. And after my kids played "spray dads weather station with the hose" we are setting backyard records left and right. Can you even get a temp sensor anymore for a vantage vue? I've had the thing for 15+ years.

85 now will be interesting to see 11 number

Yes, definitely accurate for that particular strip of concrete

I was about to say last year we did that.

Hey Don, My point in thanking you for your post was agreeing with you about Chris Martz. Chris is both openly dismissing the contribution of AGW in these cases and is also dead wrong about the use of the term “heat dome”. But at the same time, I disagree with Jeff B. in calling this US heatwave one of the most “expansive”. It’s quite intense with record highs likely for a couple of days, but certainly not in a large portion of the country: This is the largest extent of the heat dome at H5 expected to produce record heat in and near the Mid-Atlantic states: Compare that to this significantly more expansive heatwave over the U.S.: 594 dm from E coast to Rockies and also N to MSP in addition to it peaking at ~600 vs the current one peaking at ~597: There are others, including the Dust Bowl years, especially July of 1936, that had some days of 100++ over a much larger portion of the U.S. In contrast, the current one is forecasted at its peak extent to have 100+ only mainly from E GA to the NYC/Hartford areas, which is not one of the most extensive in US history:

Although, likely skewed by courser models, the 07z NBM has a high (mean) of 104F for KBOS on Friday w/a std of 2F. Definitely entered the hawt'est time of the year. Won't escape (climatologically speaking) until late July. For KBOS, the mean high doesn't start getting colder until July 23rd. Was planning on staying outside for most of the day just west of Albany on Friday. May have to delay the trip by a day or two.

NWS has ticked the point click down from max temps 105-106 to 101-102 depending on where you are in wake county. Still extreme but not record shattering as originally forecast

"It's called 'summer'..."--CFACT policy analyst Meanwhile from Météo-France: The recent heatwave saw France record, on a national basis, three highest daily mean temperatures, four highest mean high temperatures, and four highest mean low temperatures on record. "Summer" doesn't describe this extraordinary climate change-driven heat. The reality from France: A warmer baseline climate makes hot patterns hotter. Key points from a recent World Weather Attribution rapid analysis: Across large parts of Western Europe, June is warming faster than any other month. In addition, daily maximum temperatures are warming faster than night time temperatures, though both are warming much faster than global warming. The hottest daily temperatures are warming at about triple the rate of global warming and night time temperatures at about twice the rate. Many capital cities are experiencing not only their hottest June 3-day period but also the hottest three-day period since 1950, according to the ERA5 dataset. However, due to global warming, these very high temperatures are now expected regularly during the summer months in many capitals. This means that a similar heatwave in June would have been about 3.5°C cooler during the day in 1976 and about 2°C cooler in 2003. The nighttime temperatures would have been about 2.4°C cooler in June 1976 and about 1.3°C cooler in June 2003. This June 2026 heatwave occurred under a circulation pattern broadly similar to historical analogues – Southerly Flow. However, a similar circulation pattern now produces significantly hotter temperatures than it did in the mid-20th century because the climate baseline has warmed. Key Points: 1) The heat was record-setting, not typical summer warmth 2) Human induced climate change contributed to the extreme nature of the heat 3) Interest-driven policy analysts are poor sources of weather/climate information; they seek to advance their employers' interests and some even resort to pushing misleading information to undermine public knowledge e.g., the flippant dismissal of the heat as "summer."

It usually is not. I'm trying to change that here at UMD. I consider myself somewhat of a Meteorologist Metrologist myself. Though I'm always humbled by those NIST people.

https://weather.cod.edu/satrad/ looping that ... it may also evap a little when it poors over the ridge lines. I guess that times about 2 pm, so the damage may be done S-E of HFD-MHT for temp wrt to cloud troubles. Have to see on that too - Heat's like this... it's a tedious ferreting to find the way it's going to fail.

Trade Alonso...are you serious? I hope you're not. We just signed him for 5 years, biggest FA signing in 2 decades--that is not happening, man lol I mean do you know how dumb that would look? Not to mention the message it sends to future star FAs of his caliber we wanna go after? "Yeah we made a big 5-year commitment to you but now half a season in...bye-bye!" Nah dude this particular take is not it, lol Now Cowser and Mayo, Ward and possibly Rogers I can see.

Going to end up with convective cloud debris today too and may even see convection begin to pop early afternoon...or maybe closer to mid-afternoon. Pretty healthy looking convective complex (at least from satellite presentation) in Quebec racing southeast

Good catch! That might explain the Euro's being a little blunted. DP handling and timing is going to be factor-able.

Found a pic from that day. May 24, 2010

Today might be an interesting test as we head into this anomaly scenario. As an entrance/threshold cross ... the most guidance stall T rises to the 87-89 range, but there are a couple ...such as the GFS, have 90-92. The test may only mean how well the guidance 2-m products ( which I hate anyway - ) are going to handle. But it "might" also be some sort of non-Markovian suggestion of how well we are environmentally materializing the virtual modeling. interesting.. It's complex though. It could also be micro-physical processes that more or less alter responsiveness ... It matters if we're at the ceiling and scratching to lift.

Beaten to the punch. Anyway...big dews here tomorrow afternoon on the 3k. I think this limits the mixing potential tomorrow which may be why highs are toned down a sliver Wed compared to Thu/Fri.

Yeah I followed that up ..it may have 68 to 70F in that range now that I think back a little harder.

can see how the lack of rain in central DE has led to dews at least 10 degrees lower than surrounding areas

06z GFS/Euro try to keep the upper 90s to 100° through Sunday, 7/5.

72F is the record high...only done in 1975 and 2003.
