As we have seen multiple times this summer, during the middle of this week thunderstorms will fire on the northern rim of heat from the northern Plains to northern New England.
Wednesday, the area at risk from the storms will span North Dakota eastward to northern upstate New York and Maine.
While storms in the northern Plains are not expected to be severe, cities in the path of the severe storms include Montreal, Quebec, Plattsburgh, N.Y., Burlington, Vt., and Caribou, Maine.
The greatest risks from the storms will be localized damaging wind gusts and frequent lightning strikes.
South of this area, within the vast area of heat and high humidity, very widely separated thunderstorms can occur through the balance of the week. However, most of these storms will occur during the late afternoon and evening hours with blinding downpours and a few lightning strikes, being their most significant characteristics.
Late in the week, a shift in steering winds high in the atmosphere will allow a broad zone of thunderstorms to sweep southeastward across the Great Lakes into more of New England and the mid-Atlantic. The late-week storms will not only break the heat wave but can also bring the risk of severe weather to more locations than the midweek storms.
Maysak has become a super typhoon over the Pacific Ocean and will bring life-threatening conditions to Yap and the Philippines.
While portions of the mid-Atlantic have enjoyed a day or two of spring warmth in March, most of New York and New England will finally break out of the persistent winter chill.
A widespread severe weather threat will target the central Plains on Wednesday afternoon after spotty severe storms in the South into Tuesday evening.
Yet another round of severe weather is in store for the Plains on Thursday, making for the third consecutive day of organized severe weather in the region.
A storm will accompany a press of chilly air during the first part of the Easter Weekend with rain and even accumulating wet snow in some locations of the Midwest and Northeast.
