Weather: Snow Now?


Snow Now?

By Marek Zebrowski
Staff Meteorologist

An arctic high, responsible for temperatures averaging about 15 degrees per day colder than normal, will dominate the weekend weather as it slowly drifts overhead. Fortunately for us, a small low pressure system emerging early Friday on the mid-Atlantic coast will track well off-shore. As it grows and intensifies rapidly, it will also stall over the George's Bank. Its influence will be felt mainly near the coast. Tighter pressure gradients will cause biting northerly winds to increase later on Friday; coastal flurries and ocean-effect snow squalls are likely on the Cape and Islands. This ocean storm will also block the eastward march of our cold high pressure system, delivering this weekend's only silver lining - fair weather, with a gradual moderating trend, is expected to stretch until the first part of next week.

Today: Partly sunny with flurries and scattered snow bursts near the coast and on the Cape. Otherwise fair and cold. High only near 35F (1C). Moderate northerly winds will increase late in the day.

Tonight: Becoming clear and very cold. Lows in mid 20s locally (-5C to -3C), high teens (-8C to -7C) elsewhere. Substantial windchill factor with persistently stiff northerly winds.

Saturday: Mostly sunny and very cold early, with somewhat milder afternoon. High 42F (6C).

Sunday outlook: Continued fair and becoming milder, with nearly seasonal highs in high 40s (89C) and lows in the low 30s (02C).
