A cold front is sagging south at the moment. Latest analysis indicates that there is a lot of instability available, but pockets of capping inversions spread out across the Great Lakes, which is likely going to suppress storms for a little while longer.
As for the Southeast, scattered severe storms have already developed and continue to meander across the region highlighted.
Now, as for the Northeast, the same cold front is sliding south, but poses a tornado threat, as well as an enhanced damaging wind threat. Analysis of instability and shearing indicates a pocket of enhanced shearing values in the enhanced risk area, with roughly 1000 j/kg of instability. Storms that manage to form in the area definitely will pose a tornado threat, but this could be confined to northern parts of the Northeast.
