DAYS 1-5 (APRIL 9-13)

Blocking continues and keeps high pressure in place through Saturday, then weakens and allows low pressure to run at the region from the southwest later in the weekend into early next week, but enough high pressure remains in eastern Canada to try to force this series of lows to the south as well as resulting in them running into dry air. To get any rain we need to rely on enough dynamics from the lows surviving, then maybe adding some drizzle to the mix via low level moisture from an eastern air flow off the Atlantic. This basically results in unsettled but not total wash-out weather Sunday into early next week. I’ll repeat here what I said in yesterday’s discussion: Any rain we can get will be welcomed as we are running a precipitation deficit of a few to several inches for the year-to-date with the latest U.S. Drought Monitor reporting abnormal dryness across most of southeastern New England, and of course the continued high fire danger.

TODAY: Sunny. Highs 55-62 coast, 63-70 inland. Wind variable up to 10 MPH with coastal sea breezes developing.

TONIGHT: Mostly clear. Interior lower elevation ground for forming. Lows 40-47. Wind variable under 10 MPH.

SATURDAY: Mostly sunny. Highs 57-64 coast, 65-72 inland. Wind variable up to 10 MPH with coastal sea breezes developing.

SATURDAY NIGHT: Increasing clouds. Lows 42-49. Wind SE under 10 MPH.

SUNDAY: Cloudy. Areas of drizzle and fog developing. Chance of rain. Highs 48-55 coast, 56-63 inland morning, then falling. Wind SE to NE 5-15 MPH, gusts to 20 MPH eastern coastal areas.

SUNDAY NIGHT: Cloudy. Periods of rain possible. Areas of fog and drizzle. Lows 40-47. Wind NE to E 5-15 MPH.

MONDAY: Mostly cloudy. Areas of fog and drizzle. Periods of rain possible. Highs 48-55, coolest coastal areas. Wind E 5-15 MPH.

MONDAY NIGHT: Mostly cloudy. Areas of fog and drizzle. Lows 40-47. Wind E up to 10 MPH.

TUESDAY: Mostly cloudy. Chance of coastal drizzle and patchy fog. Highs 49-56, coolest coast. Wind E to SE up to 10 MPH.

DAYS 6-10 (APRIL 14-18)

Look for renewed blocking, this time with low pressure generally near or just off the East Coast, an often easterly to northerly air flow here with episodes of unsettled weather but no widespread soaking rainfall. Temperatures while on the cooler side will average closer to normal due to nights that aren’t that chilly but days that aren’t that mild.

DAYS 11-15 (APRIL 19-23)

Indications for a nudge eastward of features and high pressure moving over this area which would result in mostly dry weather, cool nights, cool coast & warm inland days. Confidence remains low on the forecast this far out.

  1. Thank TK. What is the chance of rain out this way Sunday pm. We were thinking of setting the outdoor tv screen up to watch the Masters. Or maybe it will be too damp from morning? I wonder your thoughts.

  2. Major volcano eruption is happening over in the Grenadines. They started to evacuate yesterday.

  3. 54 at the airport, 61 here in JP.

    Current ocean temp: 43.88
    Certainly getting there and it is 3.62 degrees above average.
    Logan’s 54 could be a lot lower if the ocean were 3+ degrees below average. πŸ™‚ πŸ™‚ πŸ™‚

  4. The models have all changed their tune with the timing of the backdoor front for this weekend. They’re all faster now. In fact, some of them have it come through before midnight Saturday night now.

      1. It doesn’t really mean anything in regards to the synoptic rain threat. It may introduce drizzle sooner though.
