DAYS 1-5 (JANUARY 10-14)
Some areas received a coating of snow in the pre-dawn hours from snow showers and snow squalls as an arctic cold front made its way southward across the region. Some of these snow showers continue over southeastern MA at dawn but will be moving out soon, although a few additional snow showers may occur near the outer portion of Cape Cod today due to the arctic air flowing over the relatively warm ocean water nearby. We have one more very cold night on tap tonight before high pressure shifts offshore Wednesday and a warm front moves through with an increase in cloud cover but also a warm-up, with the temperature going above freezing for most as a milder southwesterly air flow takes over. A couple disturbances will pass by the region, one to the north Wednesday night and another probably to the south of us Thursday night as that frontal boundary slips back through as a cold front, but other than a brief episode of light snow with either of these, not really expecting much to happen. The energy will help ignite an ocean storm south of New England Thursday into Friday, the bulk of which will pass offshore, but it may be close enough to throw a period of snow/mix into the Cape Cod area for a while on Friday. We’ll need to keep an eye on this system just in case it ends up further northwest than currently expected. Either way, its movement into the Canadian Maritimes will help drawn down another brief shot of arctic air for the start of the weekend.
