Wet Weekend...
A coldfront will slice through New England later tonight out ahead of it there are a few sprinkles...along ther are some heavier batches of rain / thunder that may slide through later tonight with the front. The front will stall and settle over SE Mass tomorrow morning as a wave of low pressure rides along it. This will keep most of the area cloudy and showers will be ongoing over SE Mass for the first half of the day. Drier air will invade from the north during the course of the day and shove the front slightly farther south, so sunshine will come out from North to South. The air will also feel cooler with less humidity present.
With the front still in our coastal waters, ans a shortwave wrapping around a longwave trough...a new surface low will be born and will be a more prolific rainmaker aided by a persistent moist NE flow. Clouds will thicken up early on Friday and rain will break out by late morning...rain amounts could approach an inch in spots. It will be a cold, raw rain too with temps struggling to achieve 60 degrees.
That low will move on to the NE by Saturday morning but the cool, raw NE flow won't. This will essentially lock in low level moisture...we will be socked in with clouds, mist and drizzle...highs again struggle to 60.
Sunday looks to be the better of the weekend days...a low overcast will be over us in the morning. It will try to burn off for some brightening midday as winds shift from NE to SE out ahead of the final surface low...probably unsuccesful but at least we are looking at a mainly rain-free day.
The final low will swing over Sunday night and Monday morning with another round of steady rain. The storm lifts out Monday afternoon and we shift into a sunnier and warmer stretch.
