Forecast Discussion
The arctic cold front has finally passed over the region and is heading out to sea. As a result, winds have shifted to the NW, and an icy blast of air has made itself known, by dropping temperatures on the summit to sixteen below. The low pressure system situated over the ocean has not affected the summits for precipitation, but will facilitate strong winds, as high pressure begins to build, and the pressure gradient increases. The combination of arctic air and strong winds has resulted in a wind chill warning to be in effect for the higher summits today through noon, and a wind chill advisory in effect through 7 am tomorrow morning. Low level moisture will be advected into the region from the Great Lakes, and the summits will become completely obscured by clouds tomorrow. An upper level disturbance associated with a fairly unorganized area of low pressure in Northern Canada will sweep a weak warm front across the region. This will continue fog on the summits and provide a chance of snow showers overnight. Strong winds, freezing fog, and blowing snow will limit visibility above tree line. High pressure will then build from the south late tonight into tomorrow, clearing the summits and the skies above, and diminishing winds as well. Warmer air will be flowing into the region, and temperatures will rise above zero tomorrow, relaxing the severity of the wind chill values.
