Were May and June unusually dry in Madison?

While we all contended with the remarkable and dangerous smoke in the sky this past week, we also wrapped up a record dry spell in Madison’s history.

The 61 days of May and June 2023 were the driest May and June ever, with a paltry 2.01 inches of total precipitation falling. The next closest rival on this ignominious list occurred in May and June 1992, when only 2.65 inches of rain fell during the two months. Individually, May and June were the sixth-driest May and June in Madison’s history, suggesting how rare it is for both of them to be so void of precipitation. Continue reading

In research undertaken to write a recent column, we catalogued Madison’s record high and low temperature data for each calendar day employing data that went back to 1939. An interesting partition of the full year resulted from this simple analysis. Continue reading

How could we be in a fire danger this early in spring after all the winter snow?

This 2022-23 winter — December through February — was exceptional in that it was Wisconsin’s wettest meteorological winter on record, and those records go back to 1895.

The state also experienced significant snowfall in March. When the snow slowly melts into the soil, it provides needed water for plant growth. Continue reading
