Snow Expected into the Early Evening Hours

An upper level area of low pressure and increasing atmospheric moisture moving into the region will continue to bring mostly light snow to southern Wisconsin late this afternoon and into the early evening hours. 

Todays synoptic situation

The snow will persist in southwestern Wisconsin through the late afternoon hours and in south central Wisconsin into the early evening hours. The snow is expected to move into far southeastern Wisconsin by 4 pm and will last between 3 and 4 hours from the time of onset. The snow may be moderate to heavy at times from the mid-afternoon into the early evening, during the late day commute. 


Snowfall between 1 and 4 inches is expected during this time, with the majority of the snow falling between 3 pm and 9 pm. The heaviest snowfall is expected along and north of a line from Port Washington to Portage.  A burst of moderate to heavy snow during this time frame may reduce the visibility to one mile or less for an hour or two during the evening commute.  Hence a Winter Weather Advisory is in effect for most of south central and all of southeast Wisconsin from mid-afternoon through the evening. 

Snowfall today

The snow will diminish this evening.  Patchy freezing drizzle will be left in its wake until the early morning hours. Though no ice accumulation is expected on the roadways, the freezing drizzle may still cause slippery roadways.
