As this disturbance moves into the Northern Plains, wind shearing looks to develop across much of the Great Lakes. That, combined with instability and widespread favorable 850mb winds, looks to provoke a potentially interesting severe weather situation this weekend.
A squall line looks to develop along a cold front attached to the disturbance, which, feeding on the available instability and in the midst of favorable lower level winds, should be able to produce a severe weather threat that will cross the severe weather spectrum, including a chance of tornadoes. However, pinpointing the exact risks in exact areas is too tricky this far out, and should be determined around the Friday timeframe.
The Storm Prediction Center has outlined a long range severe weather risk area over much of the Northeast on Sunday. The way this is projected by the Storm Prediction Center, along with GFS model forecasts, shows that either a squall line or several bowing clusters may be possible over the weekend in the Northeast. This would be yet another time that a damaging wind event hits the northeast part of the nation in a short period of time.
