April 2016 Wisconsin Climate Summary

April 2016 turned out to be mainly drier than normal across much of the state of Wisconsin, and near normal to slightly below normal for temperatures. Coincidently, much of the state saw above average snowfall amounts, with nearly two-thirds of the state seeing above average values. The southern two-thirds of Wisconsin saw below average precipitation amounts, with the lowest amounts for extreme southwestern Wisconsin. Read on to find out more!


Just how much precipitation did the Badgerland get? In general, the values ranged from between 3 to 4" in the northern portion of Wisconsin, down to near 0.75 to 1" in western Vernon, southern La Crosse, and northern Crawford counties. The northern one-third of the state received between zero and 1.5" of precipitation above the monthly average, while those locations in southwestern Wisconsin that received the least precipitation were between 2 to 3" below the monthly averages.  In southern Wisconsin, Milwaukee received 1.80" of precipitation, 1.76" below the normal value of 3.56" for April. Madison fared a little better, with 2.11" of precipitation, 1.29" below the normal value of 3.40". Check out the below maps to see how your neck-of-the-woods fared for precipitation.

While precipitation was below normal for much of the state, temperatures were near normal for nearly one-half of the state. The western one-half of Wisconsin was near the monthly average, give or take a degree. The eastern one-half of the state observed between 1 and 3 degrees F below monthly normals. Most places saw monthly average temperatures in the 35 to 50 degrees F range. It is interesting to note that while there was quite an average temperature range across the state, one-half of the state was still near normal. This is even more noteworthy as temperatures for the month of April varied widely. For example, Milwaukee's highest observed temperature in April was 78 degrees on April 18 and April 25, but their lowest was 21 degrees on April 9 - a difference of 57 degrees. It gets even more drastic for Madison: their highest observed temperature in April was 80 degrees April 18, and their lowest temperature was 16 degrees April 9 - a difference of 64 degrees! Despite the large temperature fluctuations in April, there was just enough of both ends of the temperature spectrum to help balance out the averages to reach a near-normal monthly average temperature.

As we head into May, the talk of snowfall will eventually dissappear altogether until the Fall/Winter seasons, but (potentially for the last time for a while) let's talk about snowfall amounts across the state. April 2016 saw quite a range in snowfall amounts, ranging from less than one inch in the southwestern portion of the state, up to 15 inches of snow across extreme northern Wisconsin and into the upper peninsula of Michigan. Much of the state actually saw above normal snowfall for the month of April, while those in the southwest saw below average snowfall. The bulls-eye for 2 to 4 inches of snow below average were in Washburn and Sawyer counties in northwest Wisconsin. Monthly snowfall totals for Milwaukee and Madison were both approximately 1.5" above normal, as Milwaukee and Madison received 3.4" and 4.2" of snowfall, respectively.
