DAYS 1-5 (MARCH 3-7)
High pressure builds toward the Mid Atlantic Coast today and we remain in a cold northwesterly to westerly air flow, which then switches to a milder southerly air flow Tuesday as the high slides off the coast to our south. A warm front will send clouds our way Tuesday but most precipitation from it should pass across northern New England. Wednesday, we’ll be in a healthy southerly air flow ahead of a cold front, which will bring a ribbon of rainfall into our region during the afternoon and nighttime hours. As this slow-moving front pushes offshore Thursday, the shower threat will diminish but also become a snow shower threat by nighttime and into Friday as an upper level disturbance crosses the region. Surface low pressure will initiate too far north and east to have a major impact, with drier weather returning during Friday, along with a shot of colder air.
