Saturday Stuff

By Marek Zebrowski
staff meteorologist

A cold and sunny Friday will be a prelude to weekend weather woes for New England. A clipper-type system, approaching from the Great Lakes region early on Saturday is likely to spawn another cyclone on the mid-Atlantic coast. Although models' resolutions of this secondary system vary, there is a considerable potential for a substantial snowfall north and west of the city. With seawater temperatures near 42F (5C) and strong, onshore winds, it looks like all coastal locations will be spared much shoveling. By nightfall on Saturday the secondary low is likely to intensify rapidly: gale force winds will buffet the beaches causing abnormally high tides and bring liquid precipitation well inland, where it may fall through a shallow layer of cold air in low levels, causing widespread icing. With the storm sweeping through Maine on Sunday, expect a bitter backlash of wintry winds for later in the weekend and into the first part of next week.

Today:Sunny and cold. High 34F (1C) with high, thin cirrus clouds dimming the setting sun. Moderate northwesterly winds will diminish after dark.

Tonight:Partly cloudy, calm and cold. Low near 20F (-6C) in the city, high teens (-9 to -7C) inland.

Saturday: Cloudy, with light snow developing. Snow should change to mixed precipitation along the coast by mid-afternoon and be washed away by rain later in the day. Inland areas may end up with over 6 in. (15 cm.) of snow as well as freezing rain after dark. Temperatures will rise from mid to upper 30s (2-4C) in town, but remain near or below freezing to our north and west. Northeasterly winds will veer through east to southeast and strengthen, approaching gale force later in the evening.

Sunday:Breaking clouds; becoming partly sunny, windy and very cold. Highs near 32F (0C) and lows 15-20F (-10 to -6C) with a chance of snowsqualls in the mountains.
