DAYS 1-5 (DECEMBER 24-28)

Today we’re on the back side of redeveloped low pressure exiting via the Gulf of Maine, but an inverted trough behind this low will pivot southward and result in some snow shower activity from northeastern MA to Metro Boston to the MA South Shore to Cape Cod (where rain or snow showers are possible) from late morning to mid afternoon. Where snow showers are strong enough, accumulations of a coating to 1 inch can occur, but I am not expecting any significant travel impact from these. We’ll also see some strong wind gusts today in association with the offshore storm system, but these will start to settle down later on. Christmas Eve tonight will be fairly quiet with just some clouds around but no precipitation expected. A trough and cold front will move through from northwest to southeast during Christmas Day and again brings the chance of some snow shower activity (rain or snow showers South Coast if it occurs that far south), but again I’m not expecting any travel issues other than perhaps some briefly lower visibilities. This system will also create some gusty winds, and more notably introduce a much colder air mass for Thursday night and Friday, but with dry weather. The next low pressure system upstream dives southeastward via the Great Lakes and passes to our south. Guidance once depicted this as a fairly robust snow/mix producer for our region, but as is often the case, it can be overdone, and what this system is going to do for us is produce a light snowfall, favoring areas southwest of Boston, during Saturday morning and midday. I’m expecting minor snow accumulation from this system at best, but it will be a snowfall with no mix as cold air will remain in control. The next low approaches on Sunday but currently the timing looks slow enough that we won’t see anything precipitation during the daylight hours from it, just increased cloud cover, with a variety of precipitation possible at night – details of that TBD.
