An approaching low pressure storm system with a history of producing severe wind and hail damage to our west is approaching the Eastern U.S. Thursday. This system is causing winds to return from the south in the Commonwealth, which is transporting low-level moisture back into the Mid-Atlantic after it was swept well to our south earlier this week from a strong cold front. This moisture will serve as fuel for scattered shower and thunderstorm development Thursday and Friday, mainly during the most unstable part of the day in the warm afternoon and early evening hours. Although this storm system is not going to produce a constant, soaking rain for the entire area (which we do need), those of you who do receive the storms could have locally heavy rainfall, damaging wind gusts and severe hail, and a lot of lightning. Those severe threats are exactly what this storm system has a history of producing. Check out all of the wind and hail reports from Wednesday into the overnight to our west and south:
The Slight Risk area for severe thunderstorms Thursday afternoon and evening covers nearly all of Virginia:
The severe threat on Friday is less certain, as there may not be as great of instability to develop for severe storms. However, the same threats of damaging winds and hail are possible tomorrow. Here is the slight risk map for Friday:
I do want to emphasize, though, that even if these storms do not strengthen enough to warrant a Severe Thunderstorm Warning, they can still produce dangerous, frequent lightning and torrential downpours that can lead to flash flooding of low-lying areas. Move indoors to safety and allow these thunderstorms to pass before resuming any outdoor activities.
