This meteorological spring (March-May) began feeling more like winter. In fact the first day of the calendar spring was one of the top 10 coldest and March average temperatures ended up being about 6 to 8 degrees below normal. Not to mention that while Milwaukee got around its normal amount of snowfall, Madison saw twice its normal snowfall that month.
Below normal temperatures continued into April and the "April showers" commenced. Milwaukee ended up with the wettest April on record and Madison, the 5th wettest.
Though the wet trend continued into May, temperatures finally made a rebound to near, or slightly above normal. Temperatures this May averaged 0.5 degrees above normal in Milwaukee and 1.9 degrees above normal in Madison. Milwaukee received 4.30" of rainfall, making it the 28th wettest May, and Madison received 6.57", tying for the 8th wettest May.
