Weather Talk: April precip tends to be more erratic than March’sAs the calendar changes from March to April, most of us know better than to assume that the weather will suddenly behave like spring.
However, due to the daily increase in day length and solar angle, April weather does tend to offer much more than March in terms of spring weather.
Average April precipitation is 1.37 inches, just two-tenths of an inch higher than in March. However, April precipitation tends to be more erratic, with a greater tendency to be much higher or much lower than average.
For example, the only time in history that March precipitation amounted to more than 4 inches was in 2009. April precipitation has topped 4 inches nine times. Average March precipitation is about 75 percent snow and 25 percent rain. Average April precipitation is over 80 percent rain and less than 20 percent snow. The average daily high temperature, which was in the 20s in early March, is 45 degrees today and rises to 63 degrees by month’s end.
