Weekly Significant Weather Outlook Update

This message provides a brief update to the significant weather outlook issued earlier in the week.

Arctic Front Passage Sunday

An arctic front will pass through southern New England on Sunday.  Snow showers will accompany the front, which will move rather quickly west to east across southern New England Sunday mid-morning to mid/late afternoon.  The period of snow showers in any one location is expected to be only a couple of hours or even less with amounts ranging from a coating to an inch most locations except possibly 1 to 3 inches across the Berkshires and the northern Worcester Hills.  The air behind the cold front will turn sharply colder with lows Sunday night zero to 5 above across most of the interior and 5 to 10 above across the coastal plain.  In sharp contrast to Saturday, high temperatures on Monday will likely only be in the mid to upper 20s despite the higher sun angle of early March, with chilly lows Monday night in the single digits to lower teens.

Snow to Sleet/Freezing Rain to Just Rain Late Tuesday and Tuesday Night

Snow will likely spread across southern New England late Tuesday afternoon or early Tuesday evening and change to sleet or freezing rain during Tuesday evening and then to just rain most areas by later in the evening.  Freezing rain may persist along and north of the Route 2 corridor later into Tuesday night given the presence of cold antecedent air near the surface.  An inch or two of snow may accumulate before the change to mixed precipitation and then rain most areas except possibly 2 to 4 inches over the Berkshires and along/north of Route 2 across the rest of northern MA before the changeover.  This is unlikely to be a major winter storm, but travel could be somewhat hazardous for a time Tuesday evening.

Looking Beyond

Looks like milder temperatures and a series of light to moderate rain events are in store for the rest of the week beyond Tuesday.  We will take a closer look at this period with the regularly scheduled outlook to be issued on Monday.
