DISCUSSION

KEY MESSAGE 1... Arctic cold front crosses the region Saturday with dangerous wind chills Saturday night into Sunday night. Below normal level temperatures persist into Monday.

KEY MESSAGE 1 DESCRIPTION... No change to the Extreme Cold Watch. An Arctic cold front will cross the region Saturday with falling temperatures in the wake of the front. At the same time, an ocean low will intensify well south of the Gulf of Maine. The pressure gradient between Arctic high pressure crossing the Great Lakes and the intensifying ocean low will support gusty winds across the region Saturday night into Monday. The combination of gusty winds and Arctic air will produce dangerous wind chills Saturday night into Sunday night. The gusty winds could also support patchy blowing snow across the favored open agricultural areas of northern Maine Saturday night through Sunday. Snow showers will accompany the Arctic front Saturday. Below normal level temperatures will persist Monday, with moderating temperatures Tuesday into Wednesday.
