Forecast Discussion

Low pressure will spread occasional rain showers through New England today, while a cold front approaches from the west, sparking a few thunderstorms to supplement. Low pressure was located just off the Jersey shore this morning, and will slowly march northwards along the New England coastline. As a result, rain showers will push through during the day, some of which could be heavy at times, as the system taps into tropical moisture. In the meantime, a cold front will slowly march westward towards the region, possibly providing enough instability to fire a few thunderstorms during the afternoon and evening hours. Precipitation will wind down after sunset as the low departs into the Canadian Maritimes and daytime heating is lost. A lingering overhead trough coupled with the listless frontal boundary will keep the risk of showers in the forecast tomorrow, with a few more rumbles of thunder possible. However, a building ridge will allow precipitation to wrap up by evening, with even a few glimpses of clearing possible.
