The cold front is plowing east this morning and will run into the hot and humid weather along the I-95 corridor from Portland to Washington D.C. The storms that develop along that cold front will become severe this afternoon, especially from Portland to Philadelphia. The main impacts will be damaging wind gusts, but moderate size hail and perhaps even a tornado can occur as well. The areas to watch for any tornado activity will be across the Hudson Valley into New England where the shear for supercell thunderstorms will be the greatest.
Wind gusts in the storms may exceed 60 mph but in most cases, 40-60 mph wind gusts will be more common. Even that type of wind gusts can cause trees to fall and backyard items to be blown around.
Once the cold front moves through, nicer weather will move in for a few days before the next round of storms comes this weekend.
