Parts of the East can expect to see higher temperatures for the start of next week.
The storm system affecting the eastern half of the country this week will finally move off to the Atlantic Ocean midway through the weekend. While temperatures immediately behind the front will be cool, a warm-up is on the way.
As the cold front retreats Sunday, a strong high pressure will take its place, centering over North Carolina for the start of next week.
The high pressure will allow for mainly sunny skies across most of the Southeast and into parts of the mid-Atlantic. The increased sunshine will allow for additional heating at the surface, helping temperatures to rise above average for this time of year.
For Monday and Tuesday, temperatures in Philadelphia are expected to be in the lower 70s, at least five degrees above normal.
Temperatures in Atlanta and Raleigh are also forecast to be about five degrees warmer than the climatological average with temperatures in the mid-70s.
The setup of the winds will also contribute to the extended warmth. The jet stream will settle just north of the high pressure, keeping out cool storm systems from Canada that would bring temperatures down.
South of the jet stream, a westerly wind flow across the southern part of the country will bring warm, dry air from the Southwest east of the Mississippi River.
These warmer conditions are expect to persist through midweek.
By the end of next week, the high pressure is forecast to slide off into the Atlantic. This will give developing storms over the center of the country the opportunity to move into the Southeast.
