Metro Boston, north shore and metro west: The bitter cold of early January has transitioned to a milder than normal period that has been in place this week allowing for a nice break from Winter. Changes are on the way however as we begin to trend cooler over the next several days and then back into the deep freeze later next week. The January Thaw comes to an end by this weekend.
A weak and rather disorganized area of low pressure approaches Friday night and moves across our neighborhood on Saturday. Any associated precipitation is expected to be light and mostly showers of rain and snow. The better chance for snow showers is across the interior. The low will try to redevelop along the coast and throw a period of steadier precipitation in here during Saturday then winding down to snow showers early night before ending. If there is any accumulation it would be through the hilly terrain along Route 495 and probably no more than an inch. That’s only a possibility.
We catch a break from the precipitation later Saturday night and early Sunday before another very quick disturbance approaches for Sunday. This system will be weak and only provide scattered snow flurries or snow showers at most. Meanwhile, colder air will begin to transfer across southern New England and this trend will continue as we get progressively colder into next week.
Skies should partially clear Sunday night followed by a mix of clouds and sun on Martin Luther King Day. Temperatures may fall back into the teens Monday night, a sign of what lies ahead mid week.
Yet another system approaches Tuesday and redevelops offshore. Models are suggesting this will happen too far out to sea, thus only a glancing blow to our area. But, it bears close watching over the next several days. It could be a complete miss as well. For the time being the idea is we may have a period of snow Tuesday into early Wednesday, or just a few flurries or snow showers.
In any event, once this system passes to our east much colder air will overrun the area as temperatures take a nosedive into the single digits at night and teens during the day on Wednesday.
