A deepening low over the Gulf of Maine will continue to lift north today towards the Canadian Maritimes as high pressure builds in from the southwest for Saturday. The pressure gradient between the two will increase winds today into the evening before relaxing early tomorrow morning as the crest of the high skirts to the south of the state. Enough residual moisture will remain behind the low today that fog and possibly some upslope snow showers will linger on the summits with the best chance for snow showers occurring this morning. Since winds were low yesterday allowing for snow to accumulate loosely, the increasing winds will whip this new snow around today lowering visibilities from the blowing snow in addition to the fog. Towards sunset, drier air will begin moving in as winds begin to shift allowing fog and clouds above to dissipate. The blowing snow may linger even after clearing as winds continue to shift. Temperatures will remain cold today as a northerly air flow continues keeping temperatures some 10-15 degrees below normal for this time of year. But a gradual return to normal temperatures is expected overnight into tomorrow as the high builds and a warmer air flow works in. Tomorrow will start mostly clear but high and mid level clouds will return in the afternoon ahead of an incoming cold front for the overnight hours.
