1:03 a.m. UPDATE:
A Severe Thunderstorm Warning has been issued for parts of Washington, Beaver, and Greene counties until 1:45 a.m. Winds could gust up to 70 MPH.
A strong line of storms is now organizing and moving into northwest Ohio, approximately 300 miles away. Right now, it’s moving E/ESE at 40-50 mph, with winds now at 60-70 mph. Watching the movement and speed now, I think it may really pick up speed shortly. The storms will be moving through the Ohio Valley over the next several hours. This line has the potential to produce destructive winds for Ohio and the potential for damaging winds for our area.
Still watching the movement and speed, monitoring if it comes directly through our area.
Channel 11 will continue to update as this develops this evening and overnight.
Mostly calm and quiet, but an isolated thunderstorms could pop ahead of this system.

Lingering leftover showers and isolated storms, but tapering off towards late morning.
Damaging Winds = right now, we can say 60+ mph
(worst case scenario = 70+ mph winds)
Heavy rain (flooding potential possible as this develops, depends on speed and rainfall rates)
Isolated Tornados (better chances in Ohio)
What could change:
Timing and severity, depending on development and movement.
