WEATHER BLOG: Moist And Unstable

As an upper-level disturbance continues to march eastward we remain in a moist and unstable environment. The trough and its associated, very potent, surface cold front will be centered across western West Virginia by daybreak tomorrow. Sunday will start off dry, but still with warm and humid conditions. Much of the region will likely stay rain-free for a good chunk of the day…this will again allow temps to climb to near 90 with our sizzling southwest flow in place.

A pre-frontal trough will begin to develop Sunday afternoon and advance west to east across the region. This will set us up with the necessary ingredients for some very strong storms to develop as a good lifting mechanism, moisture and instability will be readily available in our atmosphere. We are looking at solid chance for a few severe thunderstorms region-wide. The strongest activity is expected to hold off until the nighttime hours, setting the stage for some nocturnal thunderstorms taking us into the start of the work-week. Any thunderstorm is expected to be capable of producing damaging winds, hail and torrential downpours which could lead to flash-flooding.

Showers and thunderstorms will persist into Monday as we turn noticeably cooler with highs in the upper 70s.
