DAYS 1-5 (APRIL 3-7)…
Very active pattern, as is well known now, with “mini Winter” in early April. We have our brief snow blitz system today, the clipper Monday, and the next system quick on its heals now coming in a little earlier on Wednesday versus my earlier thinking of Thursday, and with that, it will be running into some lingering cold air and bring a touch of snow and/or mix with it (not an important system in terms of snow). By Thursday, it’s mild enough so that whatever is around will be in liquid and not frozen.
TODAY: Pre-dawn – rain/mix arrives and changes to snow from west to east, including a risk of thunder. Dawn to mid morning – mix to snow Cape Cod, snow elsewhere may fall at least briefly heavy to very heavy with very low visibility, including the chance of thunder. Late morning – snow rapidly ends west to east. Total snow accumulation coating to 1 inch Cape Cod and immediate shore, 1 to 3 inches elsewhere, but pockets of 3 to 6 inches possible, favoring the I-495 belt mainly Boston’s southern and western suburbs. Afternoon – sun and passing clouds with a slight risk of an additional snow shower. Temperatures steady in the 30s. Wind NE to N increasing rapidly to 20-30 MPH with gusts above 40 MPH all areas, scattered gusts above 50 MPH, and isolated gusts above 60 MPH but favoring the Cape Cod region, shifting to NW and slightly diminishing but still strong in the afternoon.
TONIGHT: Partly cloudy evening. Clouding up overnight with snow arriving from west to east by dawn. Lows in the 20s. Wind NW rapidly diminishing evening, then light and variable.
MONDAY: Overcast with snow, some mixing possible South Coast, accumulating 1/2 to 2 inches in most locations with isolated heavier amounts possible before ending late in the day with breaking clouds. Highs in the 30s. Wind E up to 10 MPH shifting to NE late.
MONDAY NIGHT: Partly cloudy. Lows in the upper 10s to middle 20s. Wind NE to NW increasing to 10-20 MPH.
TUESDAY: Partly sunny. Highs in the 30s. Wind NW 15-25 MPH with higher gusts.
WEDNESDAY: Clouding over with a chance of snow/mix, changing to rain late. Lows in the 20s. Highs in the middle 30s to lower 40s.
THURSDAY: Cloudy with episodes of rain or rain showers. Lows in the middle 30s to lower 40s. Highs in the 50s.
DAYS 6-10 (APRIL 8-12)…
Storm system impacts the region April 8 to early April 9 but it’s unclear this far in advance whether this will be just rain or if there will be mix/snow involved. Cannot rule the latter out. Temperatures will run below normal both days. Optimistically looking for fair and milder weather April 10-11 before unsettled weather returns April 12.
DAYS 11-15 (APRIL 13-17)…
Heading toward the middle of the month it is starting to appear that a more typical April pattern of blocking may set up, but it’s a toss-up at this point if we end up more on the fair weather side or the foul weather side. Will monitor this possibility.
