Patchy fog, light rain possible tonight; slipper roads in the morning

A thick frost and freezing fog created some slippery conditions this morning. Some bonus sunshine quickly boosted our temperatures well into the 40s this afternoon. Clouds fill in again overnight and some patchy fog is also possible again. Along with the possible fog, there is a chance for some light rain late tonight. This may end up being light freezing rain northwest of Milwaukee. To sum it up, we may be looking at slippery roads again tomorrow morning.
