Trickle Or Torrential

Another parcel of rain is streaming northeastward but there is much disparity between the meteorological models regarding the productivity of precipitation in the region. Will it be a tease with just a trickle or some torrential downpours? I am leaning toward lighter and more sprinkley rain north of the MA Pike with somewhat heavier and steadier rain farther south of that axis. In any event, tomorrow will be gloomy with a raw northeasterly breeze which will be brisk over southeastern MA and Cape Cod. Temperatures will not exceed 55 then fall back to the upper 40s tomorrow night as areas of drizzle occur. This damp weather is destined to launch Wednesday morning with a chance that some brightening and possibly a few breaks of sunshine will materialize before some showers arrive later in the afternoon. An approaching cold front with some upper level support will push the briefly heavy showers across the area with clearing to follow Wednesday night. Temperatures should rise into the lower 60s Thursday as sunshine is prevalent with most clouds draped across the northern mountains. The southwesterly breeze will freshen that afternoon in advance of a stronger cold front on the move into the region Friday morning. A few spotty brief showers are possible from this system. After that, a giant high pressure system will create a cold Friday night with lows in the 30s followed by a bright sunny Saturday with highs in the middle 50s. This sprawling high pressure system will build to the south of the region setting up a southwesterly warming wind on Sunday. Despite some patchy clouds primarily noticeable across northwestern New England, it could reach almost 70 degrees Sunday afternoon. It could warm up to the lower 70s on Monday before the next cold front arrives with a brief shower in the afternoon.
