    Weather Forecast: 30s and Sunny

    Monday night: Clear, cool. Lows around 20. Tuesday: Sunny. Highs in the lower 30s.

    (Published Monday, Jan. 14, 2019)

    There will be plenty of winter sunshine on Tuesday with highs in the mid-30s. We warm to around 40 degrees on Wednesday as a weak cold front approaches.

    Colder air takes over for Thursday as that front dips south. We're not expecting any snow or rain from this front since it is starved of moisture. The cold air, however, will allow some of us to get snow to a wintry mix before possible rain on Friday morning.

    An area of low pressure moves in from the Midwest on Thursday night. Starting with snow across southern New England, then changing to a mix to rain as temperatures warm a bit during the Friday morning drive.

    The center of the storm may pass right over Boston, so that means rain south, snow confined to the mountains in northern New England. The track is still subject to change so stay tuned for further updates and a snow totals map.

    Friday's storm exits and temperatures stay cold enough for snow as our next bigger system moves in for the weekend.

    Saturday into Sunday we could have a significant storm over us. There is a lot of uncertainty on this track at this point. The jetstream does take a more amplified pattern, which means we have some steering currents in play.

    The system has yet to even develop, so confidence is low on who will see rain vs. snow. Damaging winds are possible, as well as coastal flooding if the storm takes a more southerly track. That also would mean plowable snowfall for all of New England. If the track is farther north, that means more rain and perhaps sparing the coast from flooding as winds would be more offshore.

    Martin Luther King Jr. Day will be cold and windy. Highs into the end of the 10-day will be in the 20s, lows in the single digits.

    We will update the forecast as often as possible to keep you up to date for planning purposes. Stay tuned!
