The greatest number of tornadoes in this record-breaking tornado season has been across the southern portion of the United States, but a storm system producing late-season snow in the Rockies will result in a tornado threat from the Northern Plains to the Northeast from Monday (Memorial Day) through Wednesday.
On Monday, a moderate risk of tornadoes will be found in the northern Plains, including the eastern Dakotas and parts of Minnesota and Nebraska, according to the government’s tornado experts, the Storm Prediction Center.

By Wednesday, the severe weather threat will expand in the highly populated Northeast, a region that has generally be spared damaging thunderstorms and tornadoes so far this year. The preliminary risk area includes all of New England, eastern New York (including New York City), much of New Jersey, and eastern Pennsylvania (including Philadelphia).
Needless to say, this area will be refined in the coming days, but the danger is elevated in highly populated regions.
