If @ametsoc.org or @nwas.org ever gave out a "Graphic of the Year" award, it should go to Jay Cordeira, displaying the synoptics behind the Predecessor Rainfall Event before #Helene
It's an amazing graphic and displays our double whammy of 'rain and then more rain.'

Record heat now outnumbers record cold by more than 3 to 1 in the US. In a normal climate, they’d be equal. After billions of years of natural hot & cold cycles, human forcing has now overtaken nature as the longterm driving force of our present & future climate.

Very fall like August start in Upstate SC due to persistent Cold Air Damming, #CAD.
Greenville, SC had 4 consecutive days (2,3,4,5 Aug) w/ a high 🔽 75F. Unprecedented in #KGSP 63-yr record for this time of year.
Yet only 10 days removed from back-to-back 100F record highs in late July. 📈📉🎢 #SCwx

Japan broke it's All-time NATIONAL heat record for the 2nd time in... checks notes... less than a week!
It's not coincidence. It's climate change.
Japan is surrounded by the most anomalously hot water on the planet right now. The city of Isesaki hit 107 - it's in a valley NW of Tokyo. 1/

The average July 2025 dew point temperature for the Lower 48 was 1.2F above the 1991-2020 normal. Most areas of the map are dark green or blue - except for the very dry Southwest.

On a more serious note - temperatures will already warm up again tomorrow, with highs nearing 90 again along I-95 [left].
There's just one thing still missing from this seemingly typical summer day - the humidity [right].
How come? (short thread below)

A pretty rare and hot forecast for our area.🔥🌡️ A temperature of 100° is relatively rare in any given year in Charlotte. Multiple 100° days in a year are even rarer, and the rarest of them all is 5 in a row. It's only happened once in our history since 1878. Stay cool and stay hydrated. #cltwx

🌡️ NC Heat Health Alert System update: the entire state—and much of the US—is having a very hot week. Even the Appalachians hit a heat-index of 90–97 °F today; up there that’s the level where ER visits jump. Heat is, by far, our deadliest weather hazard.

Population estimate for exposure to Extreme NWS HeatRisk at some point over the next 7 days. At least 94 million potentially exposed. Impacts likely in most health systems, heat-sensitive industries, and infrastructure. Stay hydrated, avoid direct sun, check on the elderly and pets! #HeatWave2025

Oh no! Several of the Regional Climate Centers have had their funding lapse through DOC/NOAA. These institutes are critical for connecting weather and climate data and services to local communities across the United States.
