DAYS 1-5 (APRIL 3-7)
No big changes from yesterday’s ideas, so this discussion will be more or less a summary of that, advancing one day. Our pattern is unsettled, with frequent temperature changes as a frontal boundary is pulled this way and that way by the weather systems governing the pattern. We became entrenched in the marine-chilled air yesterday and remain there as today starts, but a warm front, causing a few showers and areas of fog and drizzle this morning will pass by and lead to improved weather – breaking clouds and milder air – this afternoon. Looking for lots of clouds, breaks of sun, and temps rising through the 50s to around 60 at Fenway for the Red Sox home opener. Tonight, we stay mild, but a cold front moves through the region as low pressure passes north of our region early Saturday. High pressure building quickly in behind that departing system in eastern Canada will help drive a northeasterly air flow back into our region Saturday with a drastic cool-down after a mild start. I do expect the day to be generally dry with no more than an isolated shower with the front and patchy drizzle later in the day or at night with the increased low level moisture from the ocean. Sunday starts much the way Saturday ended, and another low passing to our north will drag a quick warm front / cold front combo through. This time the warm up will be quite brief and also dampened, literally and figuratively, by fairly widespread shower activity. Once this front clears the region Sunday evening, we’ll see drier but chilly air arrive and persist through Monday, along with a gusty breeze. Tuesday, along comes the next upper low and attendant surface disturbance, along with below normal temperatures, bringing us the chance of a little bit of rain, sleet, and even wet snow, though this does not look like a significant system at this point in time.
TODAY: Cloudy morning including areas of fog and drizzle along with isolated to scattered passing showers, favoring eastern MA and southeastern NH. Clouds break for partial sun afternoon.
