1. The severe weather today and tomorrow will remain in the Midwest and lower Great Lakes. As the trough digs into the Midwest the next 24 hours, storms will develop over the Midwest and some of the clusters of storms will produce damaging winds and flooding rains. That trough will eventually dig into the East Thursday, resulting in big thunderstorms along the I-95 corridor in the afternoon,
2. As the second trough digs into the Mississippi Valley this weekend, a corridor of tropical moisture will set up between the Atlantic Ridge and the trough in the Mississippi Valley. As you know, I remain concerned for flooding along the Delaware River due to the fact that the river is already running high and the models are showing the heaviest rains setting up along the river per the maps below. Now, I am not saying massive flooding is coming, what I am saying is the river is running high and additional heavy rainfall may take the river higher and even over the banks. I think the bigger concern will come later in the summer when, after a wet period from July into August, a tropical storm runs north and brings heavy rains to the Northeast.
It's going to be a stormy period across the country, but the models seem to differ on the outcome.
The storm that is coming into the Plains will produce a wide range of weather including snow, ice and flooding rains.
The holiday time will be stormy in the Plains and Front Range of the Rockies. Travel will be impacted by the weather.
A swath of moderate to heavy snow to move from the Midwest through the Great Lakes.
A storm will streak out of the Rockies into the Great Lakes producing a swath of a snow along its path.
