🚨LONG THREAD WARNING🚨- Let's talk about tornadogenesis and the PBL: Markowski (2024) investigated tornadogenesis using a turbulent boundary layer in a supercell's environment and found near surface PBL structures to play an important role in the formation of a...

Saturday night was ugly for our Cherokee station. A (possible) small tornado took out our tower and did localized damage. We didn't measure a big increase in winds but did measure a pressure change. We've placed a temp tripod to continue data collection. #kswx NWS Springfield

Good morning. Our office has 6 damage survey teams out surveying damage across northern Illinois and northwest Indiana today. So far, we have 29 different paths of potential damage that we will be investigating today and in the coming days to identify potential tornado tracks.

Labor Day Weekend was busy for the UIUC Wind Engineering Research Lab team. We surveyed the damage caused by the August 28th, 2024 Mound City, SD Tornado. Crop damage along with Transmission Line failures were documented. Stay tuned for more details! #tornado @NWSAbderdeen

Thanks to all the QLCS tornadoes getting surveyed, Saturday’s tornado outbreak is now up to 74 reports.

Here are potential impacts for the upcoming strong winds Tuesday through Wednesday. Here's what you can do to prepare to help minimize impacts! #CAwx #SoCal #LA #LAwind #LosAngeles #VenturaCounty

in Lake Mary, Florida. About 4 mins from our TV station on Blue Iris Place. Two homes nearly leveled, about 6 with major damage. Path appears at least 1/2 a mile. FOX 35 Orlando

6 tornadoes confirmed from Friday night/Saturday morning. Neoga: EF-2, 120 mph, path 11.32 miles Mattoon: EF-1, 100 mph, path 0.57 miles Paris: EF-1, 90 mph, path 3.61 miles Lovington: EF1, 110 mph, path 5.06 miles Hammond: EF2, 115 mph, path 10.11 miles. Flatville-Gifford:

Today, the NWS will examine instruments at the Midland (TX) Int'l Air & Space Port to conclude if Tuesday's 111 mph gust set their all-time record during an apparent microburst. 📷 below: Stephen Allen & Priss Darrough via NWS Midland

NOAA's widely-used billion dollar disasters database is being retired, the agency revealed today, and will now span the years 1980-2024. Staff cuts, narrowing of focus (and scrutiny of climate-related datasets) are to blame. cnn.com/2025/05/08/cli…

🔥 FIRENADO 🌪️ #DeerCreekFire - San Juan County, Utah An EXTREMELY large fire whirl was observed by firefighters on Saturday, July 12 in the early afternoon being called a “vortex/tornado ordeal” by fire managers. Debris can be seen flying through the air as the ‘firenado’

inciweb.wildfire.gov/incident-video… More incredible footage of the tornadic vortex that occurred a few days ago on the #DeerCreekFire. #cowx

As my research group continues to probe the factors contributing to the #DeerCreekFire's EF-2 fire-generated vortex (FGV), one possible vorticity source appears to be coherent terrain-forced cyclonic flow in the lee of the La Sal mountains. Here are the HRRR near surface wind
