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.
A system that started in the Gulf of Mexico is coming northeast and will bring a swath of heavy rains.
A tropical low coming Northeast will produce a corridor of heavy rains.
Storms will fire over the High Plains today. Later this week, heavy rains may come north.
Severe storms will hit areas from Pennsylvania to New Jersey today. The storms will be packing high winds.
The heat is on from the Plains into the East.
The storms will continue around the edge of the heat wave.
