Discussion
The combination of an increasingly humid air mass, strong surface frontal system and a vigorous mid-level low will help to generate numerous showers in the Mid-Atlantic region from today into tonight and possible severe thunderstorms. In fact, there may be two bands of thunderstorms to closely monitor during this event- one during the mid-day/early afternoon hours and a second during the late evening. The main severe weather parameter threats will be damaging wind gusts and “flash-flooding” downpours., and isolated tornadoes are also on the table. The upper-level low will be rather slow-moving in an easterly direction and this will result in an unsettled weather day on Saturday with scattered showers and isolated thunderstorms. The upper-level will then exit off the coast by Sunday resulting in improvement to end the weekend and the weather on Monday, Memorial Day, should feature plenty of sunshine, very warm conditions, and highs well up in the 80’s.
