Pittsburgh, DC, Philly: Springlike, Then Colder
March 11, 2013; 6:50 AM
April-like temperatures have invaded the East and they will persist through Tuesday, before being erased by a cooler airmass for the middle of the week.
A typical March is like a roller coaster across the East with several warm spells only to be erased by brief shots of cold air.
It should be no surprise that the warmth across the East currently going on will not last all that long.
However, through Tuesday, AccuWeather.com Meteorologists are expecting widespread 60-degree temperatures from Buffalo, N.Y., to Philadelphia, Pa., southward into the Carolinas.
The 70-degree temperatures will be common from Columbia, S.C., through the remainder of the Southeast.
Residents of the Northeast, however, will not be quite as lucky as points farther to the south.
A wind off the ocean combined with deep snowpack in many areas inland will keep temperatures from Long Island and NYC through Boston and Portland on the chilly side. Highs through Tuesday will make it into the lower to mid-50s in New York City, while Boston and Portland remain stuck in the 40s.
Though it will remain mild to warm across the East on Monday, springtime warmups are often followed by rain.
In this case, a storm currently producing snow from Omaha to Marquette, will track eastward on Monday.
This system will bring a period of rain to the mid-Atlantic and thunderstorms to the Southeast Monday afternoon into Monday night, effectively beginning to erase the mild temperatures.
It will take until Tuesday for the rain to move into Philadelphia, Washington D.C., Richmond and Norfolk, which will allow for one more day of mild temperatures.
Behind this system Tuesday night into Wednesday, temperatures will drop as a northwest wind ushers in the cooler air.
By Wednesday, areas that were in the 60s, like Buffalo and Pittsburgh, will struggle to get out of the mid-30s.
Highs even over to Philadelphia and D.C., Wednesday will struggle to reach the lower 50s as a chilly northeast wind blows. Temperatures on Thursday will be even colder.
There may even be a few snow showers over the Great Lakes and central Appalachians as this cold air makes headway through the east.
AccuWeather.com Meteorologists will continue to monitor the warmth and impending cool spell over the next few days.
