Most of the country will experience quiet weather on Wednesday. The few exceptions will include areas along a front in the Plains and Rockies where showers and thunderstorms are anticipated.

In the Northeast, temperatures will begin to climb on Wednesday with highs reaching near normal. Later in the week, temperatures will continue to climb, with readings 5-10 degrees above normal by Friday.
Tuesday's area of above normal temperatures will shrink substantially as it moves east to the Great Lakes. Highs there will only be 5-10 degrees warmer than average for the most part.
Temperatures in the Northwest will also be a bit above normal from coastal Oregon through northeastern California, elsewhere temperatures are expected to remain near normal under clear skies. Temperatures in the Lower 48 states Tuesday have ranged from a morning low of 25 degrees at Stanley, Idaho to a high of 97 degrees at Wahoo, Neb.
