DAYS 1-5 (DECEMBER 24-28)
** WATCH FOR ICY AREAS UNTIL THE TEMPERATURE GOES BACK ABOVE FREEZING THIS MORNING **
No changes to yesterday’s discussion. Short range models will be fine-tuning the details of rain/snow line to guide us along but the overall thought process remains the same. Still expect the rain/snow line to spend most of its time near to southeast of I-95 for the Christmas morning event and a burst of heavy precipitation with possible thunder at the end. It should all by out of here by midday so afternoon travel plans will be less impacted. Current expected accumulation: 3-6 inches across north central CT, all of central to interior northeastern MA and southern NH, or basically the I-84 belt and central and northern portions of the I-495 belt with pockets of 6-8 inches favoring higher elevations, 1-3 inches along the I-95 belt including Boston and its immediate suburbs west and southwest, down through northern RI and parts of interior southeastern MA which would be closer to the 2, and then a coating from the South Shore to about the Cape Cod Canal at the end of the event. The remainder of the day would be windy and colder with a few light snow showers around. Tuesday and Wednesday we will find ourselves immersed in a cold northwesterly fair flow delivering arctic air and presenting the chance of a few passing snow showers in otherwise mainly dry conditions. An even colder reinforcement of air arrives Thursday. To the detailed forecast…
TODAY: Partly sunny. Highs 35-43. Wind NW 5-15 MPH.
TONIGHT – CHRISTMAS EVE: Clouding over. Precipitation arriving late as rain Boston south, mix/snow elsewhere. Lows 26-34. Wind light E shifting to N.
MONDAY – CHRISTMAS DAY: Overcast through mid morning with snow except rain changing to snow southeast. A brief burst of heavy snow possible with a slight risk of thunder. See discussion above for expected snow accumulations. Breaking clouds and passing snow flurries midday and afternoon. Early-day highs 28-40, warmest southeastern MA, then falling temperatures. Wind N to NW increasing to 15-25 MPH with higher gusts possible.
TUESDAY: Partly cloudy and windy. Slight chance of snow showers. Lows in the 10s. Highs from the middle 20s to lower 30s.
WEDNESDAY: Partly cloudy and windy. Slight chance of snow showers. Lows from the middle 0s to lower 10s. Highs in the 20s.
THURSDAY: Mostly sunny. Lows in the 0s. Highs from the middle 10s to middle 20s, coldest interior and north, least cold Cape Cod.
DAYS 6-10 (DECEMBER 29-JANUARY 2)
Watching 1 or possibly 2 low pressure areas that may impact the region with wintry precipitation and favoring December 30 to early 31 at this time, but there is a fair chance a lot of this may pass south of the region. Temperatures below normal.
DAYS 11-15 (JANUARY 3-7)
Similar pattern, below normal temperatures, additional threat or 2 of a winter precipitation event.
