I found out that Northern Wisconsin including Eau Claire county was under a winter weather advisory today but after looking at the weather from yesterday being projected to today I don't understand how that prediction could have been made.  We did end up with a little rain today but not a downpour. Yesterday was just warm enough to allow for no snow and with today being warmer it only makes sense that snow has no chance at falling any time soon. The surface winds are changing signaling a change in pressure. Low pressure is moving in but the center is to our south which is why we are getting rain tonight. To see just how much we could be getting overnight let's look at the wundermap surface map for radar and fronts. 
The stationary front to the east of the system is helping to form the precipitation as the warm and cool air mixess. With the system moving northeast and spinning counter-clockwise we should expect much more rain overnight making tomorrow morning very damp but it should dry up by the afternoon. The rain in Kansas is trying to move north but I think it's going to lose strength and moisture since it is on the back side of the low pressure which is typically where little precipitation happens.

For tomorrow expect warmer temps with the lower pressure and similar winds. The rain may stick around into the morning but i wouldn't count on it. Tomorrow should be a nice day in the afternoon but not nice enough for shorts. next week appears to be amazing if what the experts are saying is true.
