A big severe weather day is unfolding across the East Coast from North Carolina to Maine, with the whole spectrum of severe weather expected -- hail larger than golf balls (2.00" in diameter), damaging winds up to and over 75 MPH, a few tornadoes, heavy rain, and dangerous lightning.
The derecho I mentioned yesterday actually did play out, but it's not as strong as it could have been. It has produced about 250 miles of wind damage from northwestern Indiana to southwestern Ohio, which classifies it as a derecho. The complex continues to produce moderate damage and severe winds of 60-70 MPH across parts of eastern Kentucky right now. The derecho is moving south-southeast and will continue through the southern Appalachian Mountains and eastern Kentucky this afternoon.
Meanwhile, two areas along the eastern states -- one from PA to NC, and another in a chunk of eastern New England -- is under the gun for their own exciting weather this afternoon. The biggest risks from PA to NC include hail larger than golf balls (2.00"), damaging winds of 75+ MPH, a few tornadoes, heavy rain, and frequent lightning. The SPC issued a watch for the counties shaded in blue until 800PM EDT:
