DAYS 1-5 (APRIL 14-18)
Our preview of summer gets kicked out the door by a back-door cold front and ocean wind that arrives from northeast to southwest during today, but it will be late enough in arrival away from the coast so that we do see one more day of summer-like warmth there. As is often the case, the back-door front will not be accompanied by any precipitation, in fact, the front won’t even carry any clouds with it, as we just have a canopy of high level clouds drifting across our sky, filtering the sun and giving the sky a hazier look to accent the lingering summertime feel ahead of the front. We do see more cloudiness over the weekend as finally some low level moisture increases the cloud coverage on Saturday along with the approach of a weak low pressure system from the south, bringing a rain shower chance later Saturday to early Sunday – though this doesn’t look too widespread. By Sunday, the cloud deck will be more solid and we’ll end up cooler than Saturday, still coolest in coastal areas and a little less so over the interior. A larger scale low pressure trough will be approaching from the west as the weekend goes on. While surface low pressure is destined to pass well to our northwest on Monday, a cold front will sweep through the region from west to east, but the timing is late enough so that Patriots Day events in Lexington/Concord, the Boston Marathon, and Red Sox games should occur with generally rain-free conditions, just a mainly cloudy sky. A band of showers will then come through from later in the day through the evening, exiting to the east overnight, and setting up a return to dry weather Tuesday with a gusty westerly wind setting in.
TODAY: Mostly sunny. Highs 70-77 coast and 78-85 inland during the morning, with a sharp cooling trend coast by midday and slower cooling trend inland during the afternoon. Wind W up to 10 MPH shifting to E 5-15 MPH from northeast to southwest with higher gusts in coastal locations.
