Strong thunderstorms are possible Wednesday for the Great Lakes and Ohio River Valley, as well as from the Tennessee Valley to the Gulf Coast. Heavy rainfall is expected from the Southern High Plains through the Southern Plains.
Great Lakes and Ohio Valley: A cold front will continue moving eastward across the Great Lakes and Ohio Valley regions on Wednesday. Significant severe weather is currently not expected due to extensive cloud cover and ongoing convection from yesterday; however, some destabilization along the front is possible, leading to afternoon thunderstorms capable of gusty, possibly damaging, wind gusts.
Tennessee Valley to Gulf Coast: Between a low pressure system along the Atlantic Coastline and high pressure in the Central US, along with the front dipping down towards the Tennessee Valley, thunderstorm activity is expected for the region. A strong severe weather threat is not likely, however a few stronger thunderstorms possibly capable of strong winds or even downbursts is not out of the question.
Southern High Plains/Southern Plains:A frontal boundary will be draped across the region today, allowing for shower and thunderstorm activity. Plentiful moisture should promote moderate to heavy rainfall, with an average of 1-3 inches expected, with isolated higher amounts locally.
