Short Term (through evening ): Thunderstorm threat continues through tonight in eastern MA, RI, and southern NH, though I don’t expect any widespread severe weather. Any storms that do occur could cause torrential rain and frequent lightning. Through early evening, most of this activity will occur in RI, with isolated showers and storms popping up elsewhere.
Tonight: A cold front will slowly push across the region from west to east with more widespread showers and thunderstorms, some of which will produce heavy rain and local street flooding. Not expecting severe weather from this either (damaging wind, large hail).
Saturday: With a cold front sitting just offshore, clouds will dominate to start, then a mix of sun and clouds for the afternoon, with the atmosphere unstable enough to run the risk of some pop up showers and thunderstorms, primarily during the 2PM to 6PM time frame. Drier air pushing in at night will put an end to any of this.
Sunday: High pressure will be in control at the surface, with upper level low pressure to the north. This will result in a fair, comfortable day, with most clouds popping up over the mountains to the north, leaving the forecast area with lots of sun.
Early to mid next week: Upper level low pressure will extend a lobe southward and a disturbance coming along will cause unsettled weather Monday, with a break Tuesday as a drier slot air moves in. Additional clouds will be around at midweek with a minimal shower threat as the upper low hangs around for a couple extra days.
