A warm front will swing through Southern New England with a period of showers and downpours Friday Morning. The front will hang up somewhere in Southern Vermont and Southern New Hampshire and Northeast Massachusetts. Clearing is expected and with the warm front in close proximity, there will be the formation of strong to severe thunderstorms in the heating and the warm front serving as a trigger. Following that a cold front will swing through the area with the potential for a squall line of severe thunderstorms. The headlines depict the current thinking. Key factors include:
1.) Clearing allows for the expected heating and destabilization as modeled.
2.) The position of the warm front verifies allowing most of Southern New England to be in the warm sector.
3.) Timing of the cold front through the area and forcing around the warm front to allow for severe thunderstorm development in the 3-10 PM time window.
