With the first official heat wave possible for areas as far north as New England, this event will give you a warm welcome to summer, literally. A heat wave is an event with three or more 90 degree days in a row, and this is possible from Monday through Thursday of next week. So get ready for the heat and the sun will also be out. Barely no rain is expected during this period. Possibly some pop-up thunderstorms are possible just because it is going to be so hot! Here is the forecast map for how hot the northeast will get!
