DISCUSSION

KEY MESSAGE 1...Gusty winds through Saturday, cold temperatures Saturday night.

KEY MESSAGE 1 DESCRIPTION... The low pressure system is centered over northern Quebec and will continue to track ENE. As of this update the cold front has swept through the area. For Saturday, the remaining shortwave energy behind the front should create some showers in the north. Any showers on the back side of the cold front will be in the form of isolated snow showers in the North Woods.

In addition, the approaching high pressure behind the exiting low will tighten pressure gradients on Saturday. Winds gust are expected to reach up to 35 mph, creating possible isolated power outages. Winds will relax Sunday.

Temperatures will only rise a few degrees throughout the day on Saturday, and fall throughout the night as high pressure builds in and clouds clear. Temperatures will fall into the 20s across the north and the 30s down to the coast. Lingering winds overnight will combine with the cold temps to produce wind chills in the upper teens across the north and the 20s for the rest of the area.

KEY MESSAGE 2...Generally dry weather Sunday through late next week.

KEY MESSAGE 2 DESCRIPTION... A strong surface high pressure will elongate cross the northeastern United States beginning on Sunday and will generally control the weather through late next week. During this time, several weak frontal passages will occur. However, with only limited moisture available expect that the frontal passages will generally be dry. As the original high slides eastward on Tuesday, additional ridging over southern Canada will move into the region continuing the dry trend.
