Discussion
A strong cold front heads our way today and southwesterly winds will pick up ahead of it and there can be showers at just about anytime and perhaps a strong afternoon or evening thunderstorm. The coolest air mass of the season will ride into the Mid-Atlantic region on stiffening N-NW winds and both days of the weekend will feature unseasonably chilly conditions for this time of year. Strong high pressure moves overhead later tomorrow night setting the stage for excellent radiational cooling conditions (i.e., mainly clear skies, light winds) and this could lead to the first frost/freeze by early Sunday morning. Temperatures will modify during the early and middle parts of next week and we’ll likely have to monitor low pressure that forms over the western Atlantic Ocean.
