High pressure to our north continues to have an influence on the weather in the Mid-Atlantic region as we begin the new work week with cold and dry conditions. Temperatures are starting the day in the upper 20's in many locations and dew points are generally in the single digits - indicating this is an extremely dry air mass. Weakening low pressure to our west is push towards the Mid-Atlantic region and it should hold together enough to produce a light wintry mix here from late tonight into late Tuesday. High pressure will take control again at mid-week we’ll have a bit of a warm up compared to the chill of today and tomorrow. A stronger low pressure system will likely impact the region from Thursday into Friday with rain that can change to snow on Friday.

A broad southwesterly flow of milder air has formed on the backside of strong high pressure which is now situated over the western Atlantic Ocean. This high pressure system had its origins last week over the central part of Canada, but has drifted southeastward over the past few days. The milder air mass worked its way into the eastern states on Tuesday and it’ll stay warmer-than-normal here into the day on Friday. A strong cold front will pass through the Mid-Atlantic region on Friday night paving the way for much colder weather this weekend and signs point to additional colder-than-normal outbreaks for the Mid-Atlantic region during the second half of March. One final note about the upcoming weekend, it will be time once again to turn the clocks ahead early Sunday morning.

Clockwise winds on the back side of a strong high pressure system over the western Atlantic Ocean have produced a broad flow of warmer air from the southwest-to-the northeast and temperatures will respond noticeably here by afternoon. This warm up will actually intensify later in the week and it'll stay well above normal right through Friday. A late week cold frontal passage, however, will usher in much cooler air for the weekend with temperatures likely confined to 50 degrees for highs by the time we reach Sunday afternoon.

High pressure that first formed over central Canada has drifted southeastward over the past few days and it will emerge out over the western Atlantic Ocean by tomorrow. As a result, clockwise winds on the back side of the high have produced a broad flow of air from the southwest-to-the northeast and temperatures have responded noticeably higher across the central Plains and Upper Midwest. This warm up will expand into the eastern states by tomorrow afternoon and it’ll stay on the warm side of normal for much of the remainder of the week. In fact, 70 degrees is possible here on Wednesday, Thursday and Friday before a late week frontal passage ushers in colder air for the weekend.

This colder air mass is anchored by strong high pressure across southern Canada which will remain in control through Sunday at which time it’ll begin to shift eastward. Looking ahead, once this high pressure system shifts to the western Atlantic Ocean early next week, a big warm up will develop in the eastern half of the nation. This warm up will first develop across the central US and then it'll expand into the eastern US. Much warmer conditions will arrive here in the Mid-Atlantic region for the Tuesday/Wednesday/Thursday time frame with highs likely well up in the 60's by the middle of next week.

The days will feature colder-than-normal temperatures for early March and persistent NW winds will make it feel even colder than the actual ambient air temperature. Once this high pressure system shifts off the east coast early next week, a strong southwesterly flow of air will set up on its backside and begin a significant warm up in the central US on Sunday/Monday which will then expand into the eastern states on Tuesday/Wednesday/Thursday.
