The NYS Mesonet at UAlbany's Stony Brook site has now broken the entire network's all-time records for 1, 3, and 24 hour rainfall set previously during Ida. Now (previous): 1H: 3.79" (3.76) 3H: ~7" * (5.57") 24H 9.38" * (8.44") *Not final - may increase. #nywx #nycwx #stonybrook

2 areas of extreme rainfall over the last 24 hours in southwest Connecticut and Long Island. Both areas received 6-12+ inches! This caused catastrophic flooding and prompted Flash Flood Emergencies to be issued. The MRMS recurrence interval is greater than 200 years! #CTwx #NYwx

At 115 PM Sunday, the gage on the Housatonic River at Stevenson, CT was at baseflow levels (~582 cfs). By 6:15, after at least 10" of rain fell, level would rise 91-fold (53300 cfs!). In context, that flow is ~5 times the typical flow on the much larger CT River at Montague, MA.

🎉 Oklahoma Mesonet 30th Anniversary post for August! 🎉 On this date 17 years ago, one of the craziest #okwx events occurred when Tropical Storm Erin re-intensified over Oklahoma producing major flooding and peak wind gusts of 75 mph. #okmesonet

What a crazy 24 hours from western #CTwx to Long Island #NYwx! Here is the estimated hourly rainfall accumulation loop for the 24 hours ending at 8 am EDT, Aug. 19, 2024.

Two Images from #Vermont today: 1) Morning moisture rising from verdant forests into the clouds. 2) Subsequent moisture-laden clouds unleashing 1-2-inch per hour rainfall rates during the late afternoon. Close lightning, no rainbow, minor road washouts, happy gardens. #VTwx

Here's something you don't see too often - the center of a hurricane on radar from eastern Newfoundland! #Ernesto is certainly in an unusual spot to still be a TC. Lack of nearby trough to blame. Can see from the radar how its southwest side is mostly eroded too, cooler water

Top 3 solar days in ERCOT's history are today and the previous two days. Solar is consistently producing ~25% of our power needs on the hottest summer days with the highest demand. #energytwitter #txlege #txenergy

I will never tire of watching monsoon storm time lapses! These cameras at the University of Arizona capture the best monsoon time lapses!

Here's the MRMS derived 24-hr ARI exceedances from the rainfall that affected parts of SW Connecticut and Long Island. Jacob Feuerstein #CTwx #NYwx #StateOfFlood

Wow!

Today was officially the hottest August day EVER in Amarillo!🔥 Amarillo🌡️: 108°F (Breaks monthly record high of 107°F & daily record high of 101°F) Borger🌡️: 109°F (Breaks daily record high of 102°F set in 2011) #phwx #txwx Here's our live reaction to this information:

Dangerous, record-breaking #heat continues through Saturday for the Southern Plains before gradually waning and shifting northward into the Central Plains and Midwest later this weekend. Be sure to follow proper heat safety and check in on vulnerable individuals.

Had a good friend who used to call these days, “One of the ten best days of the millennium!”. On the Connecticut River, north of Wilder, #VTwx today. Also, #NHwx on the right bank.

A friendly reminder that the NAM Nest (NAM 3km) does *not* turn off latent heat fluxes when the lowest model level has RH values ≥ 95%. This can result in unrealistically strong tropical cyclones (e.g., 865-mb TC Barry in 2019). Don't use the NAM Nest for TC intensity! #Francine

TERRIFYING footage from a live cam in the path of the #BridgeFire in Southern California. On Mount High’s East Summit. Monster flames and even some quick firenado spin ups! #CAwx

No 2nd Trump/Harris debate. I guess Trump decided one ass-kicking was enough.
