DAYS 1-5 (JANUARY 18-22)
We’ll have a cold and blustery day today as high pressure builds into the Great Lakes and yesterday’s storm spins in the Canadian Maritimes. Tonight, high pressure slides overhead, then offshore on Wednesday. A warm front will pass by during the morning with some clouds, and the day will be the mildest of this week. Low pressure that parents this warm front will be moving eastward down the St. Lawrence Valley and its cold front will swing through the region during Thursday morning and midday with some rain to snow showers. A little wave of low pressure on the front may result in a period of snow especially across southeastern MA and RI where there may be a small accumulation before it moves away during the afternoon. This will set us up with the next shot of cold air late in the week. Friday will be mostly dry but the position of high pressure means that a northerly wind can cause some snow showers across Cape Cod. The question for Saturday’s weather is whether or not we’ll be impacted by low pressure passing to the south of the region. Some guidance says it will come close enough to give our region accumulating snow. Other guidance indicates a miss. The pattern says we’ll likely be right on the edge one way or another, and with the uncertainty in the guidance as far as a day 5 forecast goes, I’ll just lean toward a graze and can adjust either way later.
TODAY: Sun/cloud mix. Highs 28-35. Wind NW 10-20 MPH and gusty.
TONIGHT: Partly cloudy. Lows 12-19. Wind NW diminishing to under 10 MPH.
WEDNESDAY: Partly sunny. Highs 37-44. Wind variable under 10 MPH early, then SW 5-15 MPH.
WEDNESDAY NIGHT: Mostly cloudy. Chance of rain showers then snow showers overnight. Lows 25-32. Wind SW 5-15 MPH, shifting to NW.
THURSDAY: Cloudy through midday with a period of snow possible mainly southeastern MA, RI, and eastern CT that may leave a coating to 1 inch of accumulation. Increasing sun thereafter. Highs 33-40. Wind NE 5-15 MPH early then NW.
THURSDAY NIGHT: Partly cloudy. Lows 12-17. Wind NW to N 5-15 MPH, higher gusts.
FRIDAY: Sunshine except clouds and snow showers possible over Cape Cod. Highs 18-25. Wind N 10-20 MPH.
FRIDAY NIGHT: Increasing clouds. Lows 10-17. Wind N diminishing to under 10 MPH.
SATURDAY: Cloudy. Chance of snow, favoring southeastern areas. Highs 23-30. Wind NE 5-15 MPH.
DAYS 6-10 (JANUARY 23-27)
Temperatures are expected to run mostly below normal during this period. We may have to watch for a passing low pressure area to the south January 24 indicated by some guidance (but not all guidance), and another system is possible around January 26 with a chance of some snowfall. Too early to try detailing anything.
DAYS 11-15 (JANUARY 28 – FEBRUARY 1)
Temperatures near to below normal and a couple additional opportunities for wintry weather.
