Scattered thunderstorms, some of which could be strong to severe, are possible after a day of near-record heat ahead of a cold front.
The National Weather Service Storm Prediction Center placed the region under a “Marginal Risk” for severe weather, meaning short-lived, isolated strong to severe storms are possible. The main threats would be large hail and damaging winds that could bring down branches and cause power outages. The greatest threat for severe storms will be mainly between 5 p.m. and midnight, according to the NWS in Wilmington.
The afternoon balloon launch indicated that drier air in the mid-levels may inhibit widespread storm development this evening. Isolated storms are still possible with strong to damaging winds being the main threat. pic.twitter.com/j6PlPMRIlt— NWS Wilmington OH (@NWSILN) September 21, 2022
