Thunderstorm Potential for Monday

Potential for Thunderstorms Tuesday from Central Texas to the Southern Great Lakes
There will be an enhanced risk of severe thunderstorms from the Plains into the southern Great Lakes on Tuesday as an intensifying area of low pressure and associated cold front move eastward. Thunderstorms are forecast to develop during the afternoon and evening, potentially continuing into the overnight hours before weakening. Isolated supercells may develop ahead of the line. Large hail, damaging winds, and tornadoes will all be potential hazards with these storms. The highest threat will likely be centered over the western Ohio Valley region.

Risk for Thunderstorms from Northern Florida to the Mid Atlantic on Wednesday
Thunderstorms are forecast to be ongoing during the morning hours from the Mid Atlantic southward into Northern Florida on Wednesday ahead of a fast moving cold front. An approaching upper level disturbance combined with favorable wind shear may allow for a marginal risk of strong to severe thunderstorms. Damaging winds will be the primary hazard with these storms. The threat should mostly end by midday as the front moves offshore.
