A significant rain event is now getting underway in the Mid-Atlantic region and it will continue into early Friday as a cold front inches its way across the area. This cold front has support aloft from a strong disturbance that will center itself over the Great Lakes/Ohio Valley and there will be plenty of low-level moisture within a persistent and broad south-to-southeast flow of air that is forming on its front side. Showers have already pushed into interior sections of the Mid-Atlantic region and there can be an afternoon thunderstorm or two. The showers and thunderstorms will become more numerous on Thursday and Thursday night and some of the storms can reach severe levels with damaging wind gusts and even isolated tornadoes on the table. Flash flooding is an increasing concern in the Mid-Atlantic region given the already well-saturated grounds from recent significant rain events.

The cold front that generated yesterday’s showers and thunderstorms will tend to linger near the coast today as an upper-level trough slides slowly across the region. As a result, there can be a lingering shower or thunderstorm in the region and clouds are likely to persist for much of the day. Clearing skies tonight will result in noticeably cooler conditions and the next couple of days will be quite comfortable for this time of year and there should be plenty of sunshine as well. The overall pattern remains pretty nice as we get to early next week with temperatures climbing a bit compared to the early weekend levels.

The weather has certainly been active in the Mid-Atlantic/Northeast US in recent weeks and there is yet another threat for severe thunderstorm activity later today and tonight. A strong cold front will drop southeastward later today from the Great Lakes and into the region and it will be supported by an impressive wave of energy in the upper atmosphere. As a result, there is the chance for downpours later today into tonight and any severe storm can produce hail and perhaps even isolated tornadoes. Give the already well-saturated grounds, any heavy rainfall can result in localized flash flooding conditions. The passage of the strong cold front will usher in a very comfortable air mass for the region to close out the work week and begin the upcoming weekend.
