Well, well. Seems our old friend winter is returning for a late visit. After a couple of cold & dry March days, the month will wind-up with a dry & milder Wednesday followed by a cloudy & colder Thursday. Thursday’s clouds will be from an initial low pressure system passing just south of New England. Some light rain and/or snow may reach the South Coast from this system, but nothing major will occur. As we flip the calendar to April, it seems mother nature will deal us a prank for April Fools Day, in the form of a late-season winter storm!
There is much to be determined with Friday’s storm system, including precipitation type, amount, and coastal flooding impact. It is looking more and more like this storm system will feature snow versus rain for a good part of the area, but some rain is likely, at least in the early stages of the storm. Though not a tremendous amount of cold air will be around as the storm arrives, these storms can and often do make their own cold air, dragging it down from above, in a process called “dynamic cooling”. There should be plenty of moisture available for precipitation.
The next update will have a bit more detail, as I want to step slowly into trying to detail the impact of this event. For now, here’s an updated Boston area forecast!
WEDNESDAY: Mostly sunny. High 45 to 50. Wind W 5 to 15 mph.

FRIDAY: Overcast & stormy with rain and/or snow, possibly heavy at times. Several inches of snow accumulation occur where precipitation remains mostly snow, greatest chance of this will be inland and higher elevations.
