Warmth followed by cold

Foggy, damp and one big slushy - that's what is in store for us today and Friday.  Two storm systems will help continue to bring very mild and moist air up through the Great Lakes. 

One low pressure system will move northwest through Iowa today keeping the rain/drizzle and fog going throughout the remainder of the day.  The second low, a little stronger than the first, will have a little more upper level support from the jetstream as it takes almost the same track as the first.  With the snow melting to the south and a little across the immediate region the fog will continue until the second front passes late Friday night.  Once that front passes, however, any rain or snowmelt that will be left on the roads, parking lots or sidewalks could very well freeze as colder air filters in behind.  You'll more than likely feel a difference if you head out early Friday evening and by the time you wake up Saturday morning.  Just make sure you take it easy when traveling on Friday as it may become a little slick. 

If your travel plans maybe take you up north or to the northwest snow is what you'll likely run into as Winter Storm Warnings and Winter Weather Advisories have been issued for central Minnesota and through the Dakotas.
