⛈️ Today — Thursday, Sept. 3
The SPC has a Slight Risk (Level 2/5) covering portions of the southern Great Lakes into the Mid-Atlantic, including areas from Ohio/Pennsylvania toward western New York.
Primary threats:
* 💨 Damaging straight-line winds — biggest concern
* 🧊 Large hail
* 🌪️ Low tornado threat, but an isolated tornado can’t be ruled out
* ⛈️ Storms may organize into clusters/lines during the afternoon and evening.
For the Ohio Valley, storms are expected to develop/organize during the afternoon and move eastward toward OH → PA → NY through the evening
Severe weather possible across two separate regions today!
Scattered severe thunderstorms are expected to develop from the southern Great Lakes into the Mid-Atlantic later today and tonight. A stalled surface front will help focus storm development, with the potential for a few organizing clusters capable of producing strong to severe wind gusts.
A separate Slight Risk covers the northern Great Plains into the Upper Midwest, focusing on North Dakota and northwestern Minnesota. Favorable wind shear will support a few supercells capable of producing large hail and severe downbursts this afternoon and evening.
