While Monday’s rain will be accompanied by an increase in humidity in the southern mid-Atlantic, the concern for thunderstorms to produce isolated damaging winds should mainly be confined to the South. As Monday’s rain departs, residents will want to take full advantage of the milder and drier Tuesday that will unfold. More rain spreading into the mid-Atlantic on Tuesday will indicate that the dry spell will not last long. At the same time, another band of rain and thunderstorms will rotate into the Ohio Valley and Great Lakes at midweek before slowing swinging through the rest of the Northeast Thursday into Friday. Once again, residents will be facing disruptions to travel

A line of shallow convection is along an eastward moving cold front from southern lower Michigan southward into extreme northwest Ohio and eastern Indiana. Nevertheless, model guidance suggests potential for a few thunderstorms to develop along the eastward moving line as it crosses Ohio this afternoon and evening. Mid-level southwest winds will provide sufficient vertical shear for a few strong storms to develop with potential for locally strong wind gusts to occur. A small portion of the state has been placed in a marginal risk whereas, the western and part of the central areas of the state have been placed in a thunderstorm risk. Storms may be severe in some areas

We are continuing monitoring thunderstorms that will be moving in to the area. The main question will be the timing. The Storm Prediction Center has backed off a bit on the areal coverage of severe probabilities, with areas northwest of Pittsburgh, having the chance of seeing storms with damaging winds and large hail. Timing would be during the late afternoon and evening, with the risk expected to end by midnight with the loss of daytime heating. We will continue to update the forecast as it changes. *images are property of the NWS*
