The images below are from the NMM model showing the simulated radar for Tuesday and the total rainfall through Wed morning. As you can see, we have a squall line shown clearly on the simulated radar from NY to Virginia. It's going to be one of those thin lines of storms with heavy rains and gusty winds, but very little lightning. When the line goes through winds will whip-up to over 40 mph and the rain will be intense.
I think given the recent dry weather, most areas should be able to handle the heavy rains. Flooding will be confined to urban flooding and small streams and creeks.
Storm next week will bring many impacts which includes high winds, snow and heavy thunderstorms.
Light snow events through the weekend. Potential big storm next week prior to the holidays.
Confidence on the storm this weekend remains rather low.
The first storm brings snow across the northern Plains. Weekend storm could produce some heavy amounts but track differs with the models
Southern branch of the jet gets energized with storms this weekend and beyond.
Southern branch of the jet gets active with storms which means some snow but more rain.
