Northeast to Shiver From Winter Chill on Sunday

The first full day of spring will give residents across the Northeast a taste of the new season, although the milder weather is not here to stay.

A cold front is forecast to sweep across the Northeast by Sunday, ushering chilly Canadian air across the region that will linger into the start of the new week.

Temperatures are not expected to plummet as low as they did during the bitter blasts of February, but afternoon highs are still forecast to run 10 to 20 degrees below normal on Sunday and Monday.

This translates to afternoon highs generally in the middle 30s to middle 40s across the mid-Atlantic and around or below freezing across much of New England.

Although temperatures in some areas may not climb above freezing on Sunday and Monday, snowmelt can still occur due to the high sun angle this time of year.

The melting snow can turn problematic, however, as it can refreeze after sunset, leading to icy roads and sidewalks.

The higher sun angle during the afternoon can also make it feel warmer than it actually is. This is one of the facts taken into account when determining the RealFeel® Temperature.

The chilly air will not be limited to just the Northeast during the first part of the new week.

"The cold air will even reach the Carolinas by the start of the new week," said Meteorologist Jordan Root.

"After reaching the upper 60s and lower 70s over the weekend, highs in the 50s will be felt for many on Monday in North Carolina," continued Root.

Temperatures are expected to moderate heading into the middle of the week as highs all along the Eastern Seaboard return to more seasonable levels.

People across the East should not get used to this milder weather though as chilly air is forecast to return to the region before the week comes to a close.

"We're just not getting out of winter all that fast," said Senior Meteorologist Henry Margusity.

This appears to be the overall pattern in the East through the remainder of March with a shot of cold air being followed up by a day or two of milder weather before cold air returns once again.
