Discussion
High pressure over the western Atlantic will pump much warmer air into the Mid-Atlantic region today on southwesterly winds and we’ll experience our first 80+ degree day of the season. A cool front will arrive late tonight and there can be showers and thunderstorms ahead of it anytime from later today through the late evening hours. This front will stall nearby on Saturday and low pressure will drift along the boundary zone on Sunday producing more clouds in the region, a threat of showers, and overall cooler conditions. It’ll turn even cooler during the early part of next week and an overall damp weather pattern will continue through at least mid-week. Elsewhere, a tropical system is very likely to form this weekend over the southwestern Atlantic – the first of the 2020 Atlantic Basin tropical season - and it may very well contribute to the formation of a coastal storm in the Mid-Atlantic region during the middle of next week.
