There’s a 40 percent chance that the National Weather Service (NWS) will issue a storm watch for northeastern Indiana and much of Ohio (see map above) this afternoon, according to a mesoscale discussion that the NWS Storm Prediction Center (SPC) issued at 2:33 p.m. EDT. SPC meteorologists indicated that a threat of isolated severe storms might develop this afternoon, with straight-line wind damage and hail being the primary threats. The SPC said it will continue to monitor the situation for the possibility of issuing a watch later this afternoon.
