Cloudy and breezy Tuesday ahead of storm system

It's been a gloomy stretch of weather and today was no different. Overcast skies continue tonight with lows in the lower 30s. More clouds can be expected tomorrow as a southeast breeze picks up ahead of our next storm system. We are tracking a developing storm system swinging out of the Rocky Mountains. The main area of low pressure will track to our northwest, which means rain for us Wednesday. However, computer models are indicating a secondary low develops to our southeast, which would draw in enough cold air to transition our precipitation to some snow Wednesday night. Some accumulation will be possible, mainly northwest of Milwaukee.
