A warm front is passing through the region this morning with some shower and thunderstorm activity and it'll turn warmer and more humid as the day progresses. In addition, as a cold front approaches early tonight, this change in air mass will set the stage for potentially strong-to-severe thunderstorm activity later today and tonight across the Mid-Atlantic and Northeast US. Low pressure has pushed northeastward out of the central Plains and into the western Great Lakes and it will take a sharp right turn later today and head towards the Northeast US. This low pressure system will strengthen as it approaches the NE US into what is likely to be a rather favorable environment for severe weather, including the risk of tornadoes. High pressure takes over on Friday and the work week will end with lowering humidity and comfortably warm conditions.

This may not be the conventional pattern for severe weather in the Mid-Atlantic and Northeast US, but it bears close watching. An upper-level disturbance and associated surface low pressure system will actually travel northeastward later today from the Northern Plains to the western Great Lakes and then take a sharp right turn to the southeast and head right towards the Northeast US. At the same time, a warm frontal system will pass from south-to-north through the Mid-Atlantic region in the overnight hours and this will set the stage for a much warmer and more humid day on Thursday. All of this could very well end up resulting in severe thunderstorms late tomorrow and tomorrow night across the Mid-Atlantic and Northeast US with damaging wind gusts and large hail as the primary severe weather risks and there is certainly the potential for tornadoes as well.

High pressure to our north will keep control of our weather for another day with sunshine and pleasant conditions, but a warm front will arrive in the late night hours. As a result, the chance of showers and thunderstorms will increase after midnight and Thursday promises to be a warmer and more humid day with a continued chance for rain and some of the thunderstorms late in the day or tomorrow night can be on the strong-to-severe side. A cold front will then arrive early Friday and high pressure will build in as we close out the work week.

The steady rain is over, but it’ll remain unsettled today as upper-level low pressure only grudgingly pulls away from the area.
