Forecast Discussion
Weak high pressure cleared the summits and the skies above overnight. Lingering low level moisture provided the conditions for an undercast. The high will crest overhead early tomorrow, and slide east and out to sea. Winds will shift to the south, and warmer air will filter into the region ahead of the cold front, increasing temperatures and cloudiness throughout the day, providing enough moisture to plunge the summits into the clouds late. A strong low situated north of the great lakes, and represented at the surface and upper levels, in Canada will spin a low right off the Jersey Shore. As the coastal storm travels northward, precipitation will overspread the region beginning late today, and continue precipitation through the forecast period. As the intense Canadian low travels east, it will drag an arctic cold front across the region tomorrow, and redevelop with the coastal low. After the frontal passage, winds will shift to the west, ushering in the icy blast of arctic air. Strong high pressure will force its way south east from Canada. The combination of the strong high pressure and strong low will increase winds on the summit for Sunday, with gusts approaching and possibly exceeding the century mark Sunday evening. With falling temperatures, drastically increased winds, and lots of new snow, wind chills and visibility will be at dangerous levels. Visibility above treeline for Sunday can approach white out conditions, with freezing fog and blowing and drifting snow. Wind chills will start reasonable for most of the forecast period, but deteriorate quickly, to values just shy of advisory criteria before evening.
