The atmosphere will be unsettled most of the upcoming week leading several chances for rain and even a risk for thunderstorms. A few have the potential to be severe.
Monday a low pressure system approaches from the west. A surface boundary is already in place across northern Ohio. This boundary is an area that will provide an extra lift to any storms that develop.
The greatest risk for severe weather is for areas north of I-70, specifically northeast Mercer County, northern Shelby County, Auglaize County, and Logan County. This area will be lacking storm energy. Therefore large hail is not likely. The main threats will be wind damage and a possible tornado.
A warm front will move into the southern half of the Miami Valley. This area will have more storm energy, however, there doesn’t look to be enough lift for severe weather to be likely. Thunderstorms will be possible through the afternoon and evening.
We should see a break overnight as the low pushes to the east. A few showers can’t be ruled out. A few isolated storms are possible late Tuesday morning and throughout the afternoon.
The next chance for severe weather comes on Wednesday. The Storm Prediction Center has the Miami Valley under a Marginal Risk for severe weather. This is the lowest risk level out of five. A marginal risk means there may be an isolated severe thunderstorm. Most of the Miami Valley will likely not see a severe thunderstorm. It does mean you should be weather aware and go over your safety plan to be prepared.
