The current weather map depicts an elongated area of high pressure that is stretched from Maine southwestward to the Mississippi Valley. Low pressure is off of the N.C. coast while a frontal boundary is stretched from the northern great lakes westward into the Intermountain West. The upcoming pattern this week across the Northeast and Mid Atlantic will be progressive with high pressure being replaced by a cold front every couple of days or so. In the short term, high pressure will remain wedged over our neighborhood Sunday and Monday, leaving us with a chilly night with mainly clear skies followed by a seasonable Monday.

Due to overnight temperatures forecast in the mid 30s, a frost advisory has been issued for Monday from 2 a.m. to 8 a.m. for portions of northern Maryland. As high pressure slides off the coast later Monday, the flow will transition from the east to the south allowing temps to climb by Tuesday into the low and mid 70s. An approaching frontal boundary will bring us our next chance of rain Tuesday afternoon and evening with a few rumbles of thunder possible as well.
