Remaining Cold through the Weekend

Cold air spread  into southern Wisconsin behind a cold front earlier this week. The colder air resulted in the return of wintry weather to southern Wisconsin.  Several inches of snow fell from around Montello and Berlin east to Fond du Lac and Sheboygan on Tuesday and Wednesday.  The rest of southern Wisconsin experienced repeated bouts of mixed rain, sleet and snow, with a period or two of light freezing rain or drizzle on Wednesday. Much heavier snow fell to the north, through the Green Bay area.   

Cold Canadian high pressure strengthened over the western Great Lakes and Wisconsin on Thursday, and will remain the dominant weather influence through the weekend into early next week.  A large area of low pressure over eastern Canada and the northeast U.S. will remain nearly stationary into next week.  Cold north winds to the west of the low pressure area will continue to reinforce the cold temperatures over Wisconsin and all of the Great Lakes.

Late March Cold Upper Air Pattern

Despite some sunshine through the next few days, daytime temperatures are only expected to reach the upper 20s to middle 30s through the weekend, into early next week.

Below is a graph depicting the forecast high and low temperatures in Milwaukee through next Thursday, along with the normal temperatures expected for this time of year.  Normal high temperatures for late March are in the upper 40s, reaching 50 by the 31st.  Normal low temperatures are in the upper 20s to around 30.  

Temperatures are expected to remain 10 to 20 degrees below normal the next seven days, however they will begin to moderate by the middle of next week as the Canadian low pressure area finally weakens and moves into the northern Atlantic.
