    (Published Wednesday, Feb. 20, 2019)

    Quiet weather is expected during much of the day with highs in the 20s to 30s. Clouds will thicken by the afternoon in advance of the system that will arrive Wednesday night.

    With cold air in place, all of the precipitation begins as snow. That’s why we have declared a First Alert: because snow and a wintry mix will impact your travel Wednesday night and Thursday morning.

    The snow should arrive around dinner time across Central Massachusetts while places in Western Connecticut and along the Berkshires will see the snowfall any time after 4 p.m. Snow accumulations will be very limited over southern New England, where most locations could get anywhere between 1-to-2-inches while a dusting to an inch is forecasted for the Cape and Islands.

    The farther north we go, the more we see. So areas north of Route 2, are in the 2-to-5-inch range while the mountains in New Hampshire and Maine get between 6-to-8-inches.

    Most of the snow is done for areas south of the Mass Pike around 2 a.m. with ice being the main concern during the pre-dawn hours because it will create a glaze over fresh snow, making it slick and slippery on the roads mainly on untreated surfaces.

    We don’t expect this to be a major ice event so we don’t anticipate any power outages. This area of low pressure comes to us from the mid-Atlantic, so it will be a fast mover and it also taps into warmer air, hence the quick changeover from snow to ice and then to rain.

    Most of the rain and snow should be over by the morning commute, except over Maine where it will continue to snow, but slick spots can’t be ruled out especially north of the Pike. As this system retreats, clouds will give way to sun and winds will ramp up out of the southwest allowing for a quick rise in temperatures, highs will soar into the 40s and even some 50s over Southern New England.

    By Thursday night, temperatures fall back into the 20s to near 30 with a steady breeze. Friday is back to reality with temperatures in the 30s but with a good amount of sunshine, a great way to end the week.

    The weekend is split. Saturday is the best day for your outdoor activities as it stays dry with seasonable temperatures while Sunday looks messy, as another system advances quickly with a wintry mix before changing over to rain for much of the region.

    Our exclusive 10-day forecast indicates a pleasant Monday with highs in the upper 30s and 40s with high pressure still in control Tuesday morning. Another storm comes in Tuesday night with a shot for more snow as it looks colder by then. Our active weather pattern continues and we will keep you informed every step of the way.
