Forecast Discussion

It looks as if the active weather will once again be suppressed south of New England, as a major Nor'easter is gearing up to strike the mid-Atlantic. High pressure will build in today before an upper-level trough digs in to the eastern US tomorrow. Morning fog will burn off by noon time today as the high totes more stable air into the region, revealing a bit of sunshine during the afternoon. Winds will continue to relax as well amidst moderating temperatures, creating an uncharacteristically mild day atop the summits. The high will crest over New England tonight, which will result in a calm and mild night. Clouds will be on the increase, however, as an area of low pressure develops off the Carolina Coast and marches northward. This will spell out a cloudy day tomorrow with a slight chance of a few flurries as moisture from the low works its way into the region, amounting to no more than a trace or so. Winds will remain modest out of the east tomorrow with the lack of any significant pressure gradient.
