Discussion
A cold frontal system will edge closer to our region later today and low pressure will form along its slow-moving boundary zone. As a result, the threat for showers and thunderstorms is quite high right through tonight and any rain that falls can be heavy at times with localized flooding a threat. The front will stick close enough to the region on Friday to continue the threat of showers and thunderstorms and temperatures will be noticeably cooler as we end the work week. An upper-level low will then move directly overhead of the Mid-Atlantic region at the beginning the holiday weekend resulting in cool conditions for early July and a lingering chance of showers and thunderstorms on Saturday. The weather should show some improvement on Sunday and then Monday will likely turn out to be the warmest day of the long holiday weekend with the most sunshine. Elsewhere, an impressive tropical system will enter the Caribbean Sea early this weekend and will have to be closely monitored in coming days.
