DISCUSSION

KEY MESSAGE 1...Potential for fog tonight and Saturday night, posing minor travel complications.

KEY MESSAGE 1 DESCRIPTION...Relatively dry conditions tonight through Saturday. High relatively humidities and low winds, result in some fog development in valleys tonight, and along the coast and valleys Saturday night. This fog is expected to cause visibility reductions, which could impact any early morning travel.

KEY MESSAGE 2...A cold front passing through the area Sunday will bring rain to the area, then light snow north and west Sunday night.

KEY MESSAGE 2 DESCRIPTION... A large trough from the Midwest enters the area Sunday, with a strong cold front out ahead of it. Rain will develop and move east over the area throughout the day. Widespread 0.5 to 0.75 inches of rain is expected for the area. As the front passes, temperatures will drop and lead to snow as precipitation exits the area late Sunday night. The greatest chances for snow are in the North Woods and St. John Valley as temperatures will drop there first. 0.5 to 1 inch of snow is possible from the Central Highlands north. This precipitation could lead to rivers slowly rising but flooding is not expected.

KEY MESSAGE 3...Behind the cold front, temperatures fall into the 20s which could cause areas of ice on roads, potentially impacting the Monday morning commute.

KEY MESSAGE 3 DESCRIPTION...Cold air behind the front will drop temperatures, with freezing temperatures down to near The Airline. Water on roads could quickly freeze as temperatures in the north fall into the 20s overnight. This could lead to some slick roads, impacting travel for the Monday morning commute. A shortwave behind the front could cause some light snow showers in the north Monday. Temps fall below freezing again Monday night.
