A taste of summertime heat will make its presence known through a large part of the country this week as heat from the south makes its way north.

While a late-season storm will bring snow and cold across portions of Idaho and Montana, the mercury will soar into the 80s and 90s from southern California to Michigan to Maine by the middle of the week.  High pressure anchored over the Mid Atlantic on Wednesday will help pump up temperatures along the U.S. East Coast to some of their highest levels of the year yet.

Wednesday and Thursday should feature the warmest readings across the largest part of the country before an arriving frontal system cools things down. In New York City, a high of 83 and is expected those days while 87 and 89 are forecast for Philadelphia. Washington, DC will be warmer with highs of 86 and 90 expected while Boston will be a touch cooler, but still warm, with highs of 80 and 78 those days.
