NOTE: I WILL BE ON VACATION FROM JULY 4 TO JULY 8. BLOG RETURNS JULY 9.
1. The distribution of severe weather the next two days is a tough one. The first impulse is making its way across the Great Lakes, and storms should develop along the warm front coming north. Basically, that front does really separate warm and cool air masses but separates dew points in the 50s versus the 70s.
I do think storms will roll all the way to Virginia by this evening, following along the warm front. I see dew points in the 70s coming up through Virginia this morning, so we need watch for severe storms enhancing coming off the West Virginia mountains.
Another band of heavy storms will develop late this afternoon across parts of southern Michigan and Ontario as the cold front slides southward.
In all cases, the storms' impacts will be mainly gusty winds and lightning.
2. The 4th, I think, with the front still tailing across the Northeast into New York, we still have the opportunity for severe storms but probably a broken line of storms as most of the support is running off the coast and away from the front.
3. A ridge is going to expand later this week, so it looks like areas from I-80 on south are going to get hot with the big cities from NYC on south heading back to the 100-degree mark.
At least two areas of heavy rains through this weekend may result in flooding problems.
Heat and Humidity will attack the trough and result in heavy rains and heavy thunderstorms.
Severe storms will develop across New England this afternoon and may produce damaging winds and even another tornado.
A busy weekend for the Midwest and Ohio Valley as severe storms will hit ahead of the cold front.
Severe weather will rip across the Northern Plains today. Parts of Canada may see tornadoes.
Severe weather will be the focus the next couple of days. Tornadoes may hit western Canada.
