Will May’s weather continue to be pleasant?
As we head from early to late spring during the month of May, there are a number of ways to measure this progress. One way is to consider how often we experience a temperature 90 degrees during May.

What an amazing warm spell! March 14 was the first day of five consecutive days in which record-high temperatures were set in Madison. This matches the longest consecutive-day streak for setting record highs in our city’s history (the other two times were in the 1950s). Continue reading
