Expect scattered showers on Thursday, mainly in the afternoon. Highs will be in the lower to middle 60s. Friday will be mostly sunny with a high around 60. Rain is expected on Saturday. Some areas may see some snow mixed in.
Confidence is increasing on a strong low pressure system tracking from the central Plains across central Illinois on Saturday and Saturday night.  The atmosphere would be cold enough to support a period of wet snow or a wintery mix across much of southern Wisconsin.  However there remains uncertainty regarding the exact track of the low pressure system and the low level temperature profile across southern Wisconsin during the time of peak precipitation.    This Spring storm has the potential to bring a period of moderate to heavy wet snow to the area on Saturday and Saturday night, along with strong east winds. Everyone should stay on top of the forecast for this approaching Spring storm.
