DAYS 1-5 (MARCH 8-12)
The March wind was living up to and even a little beyond its reputation yesterday, and while that wind will still be with us today, it won’t be as fierce. At least this time, it’s not accompanied by arctic air, just a typical March chill, and that climbing sun angle and 3+ minutes of daylight per day addition makes a difference as we move through the final days of winter… Reminder: Don’t forget if you have clocks that need manual setting, Daylight Saving Time begins at 2:00 a.m. tomorrow (Sunday). The next several days will display an active weather pattern, but an “active” weather pattern does not automatically translate to a “stormy” weather pattern. Let me explain further. We’re going to be impacted by several weather systems during the next 5 days that bring weather changes, and none of them are big storms. Let’s move through the scenario step-by-step. The early to mid portion of this morning will feature a deck of clouds over southeastern portions of the WHW forecast area, i.e., southeastern MA and parts of eastern CT into RI. This is from a disturbance passing to our south. During the day today, low pressure scooting quickly across southeastern Canada will drag a sharp cold front across our region from west to east. This will bring some cloudiness and perhaps a passing snow shower. It will also shift a gusty westerly breeze to a strong northwesterly wind, and while gusts will not be as powerful as what we saw yesterday, the 35 to 45 MPH range is easily attainable this afternoon. This leaves the possibility of additional tree damage and isolated power outages. The period of strongest wind will be short lived, and the wind will ease up tonight as the pressure gradient relaxes. The front that went by will sit not too far to our south and as it drifts back in our direction on Sunday, look for a fair amount of clouds, especially over southern portions of our region, where a few patches of precipitation – sleet or rain – can occur. Where this does happen, it will not have significant impact, and most of the region will stay dry with limited sun. Another low pressure area will move rapidly east southeastward just north of our region Sunday night to early Monday, dragging the frontal boundary back through as a warm front briefly before driving it southward as a cold front again. This transition may be accompanied by a few rain and snow showers Sunday night and early Monday, but again with little impact. An episode of fair weather lasts from midday Monday through the day Tuesday, and with a narrow area of high pressure sliding in and then off to the south, and air flow between it and an approaching cold front gives us a shot at 60+ for high temps on Tuesday in parts of southeastern New England, but away from the influence of a southwesterly breeze off ocean water – so this would mean away from the South Coast having the higher chances of seeing that. But don’t run outside to grab the lawn furniture and open the pool, because a strong cold front sweeps through that night and puts an end to the very brief warm up, sending us back to more typical March weather by Wednesday. Pending some details to be worked out, I do see a possibility that Wednesday may lack sun and be about 20 degrees cooler than Tuesday. Time will reveal if this meteorological notion will come to be or needs adjustment, but keep in mind the potential.
TODAY: Variably cloudy. A passing snow shower favoring areas north of I-90 midday and afternoon. Highs 32-39. Wind W 10-20 MPH, gusts to 30 MPH, shifting to NW 15-25 MPH with gusts 35-45 MPH.
TONIGHT: Partly cloudy. Lows 20-27. Wind NW 15-25 MPH early, diminishing to 5-15 MPH overnight.
SUNDAY: Considerably cloudy – limited sun. A couple brief periods of light rain and/or sleet can occur mainly I-90 belt southward. Highs 37-44. Wind W 5-15 MPH, a few higher gusts.
SUNDAY NIGHT: Mostly cloudy. A snow shower possible. Lows 27-34. Wind SW 5-15 MPH.
MONDAY: Variably cloudy. Chance of snow showers except rain or snow showers south of I-90 during the morning. Highs 43-50. Wind SW 5-15 MPH, higher gusts, shifting to NW.
MONDAY NIGHT: Partly cloudy. Lows 33-40. Wind NW under 10 MPH shifting to SW.
TUESDAY: Partly sunny. Highs 48-55 South Coast, 55-62 elsewhere. Wind SW 5-15 MPH.
TUESDAY NIGHT: Variably cloudy. A rain shower possible in the evening. Lows 38-45. Wind SW 5-15 MPH with higher gusts, shifting to NW.
WEDNESDAY: Mostly cloudy. Highs 45-52. Wind variable to NE up to 10 MPH.
DAYS 6-10 (MARCH 13-17)
High pressure brings fair weather to the region early in the period, then a larger scale trough can bring an episode of unsettled weather around the March 15-16 weekend. While details can’t be determined so many days in advance, the early idea is Great Lakes low pressure and a couple rounds of precipitation (mix/rain, then rain showers) with a warm front / cold front combo, and a return to fair, colder weather at the end of the period.
DAYS 11-15 (MARCH 18-22)
Potential weather irony: As we approach and reach the vernal equinox – the start of spring – on March 20, our weather pattern may resemble one you see more in mid winter, in terms of colder weather and potential storminess. Something to keep an eye on, as it’s a low confidence outlook this far in advance.
