CEDAR RAPIDS, Iowa (KCRG-TV9) -- Rain is on the way Tuesday through Tuesday night. While it’s not going to be a huge rain producer, southern Iowa has a decent shot at a soaking rain. The “cool season” – let’s say October through March – tends to have fewer times with at least an inch of precipitation (rain and melted snow) in a single calendar day.
Cedar Rapids has, on average, about eight days each year that get more than an inch. June is the peak with an average of 1.5 days. December and January are tied at 0.2 days – basically, once every five years. October comes in with 0.7 days, which is essentially two out of every three years. Other precipitation amounts such as a half-inch follow the same trend – more in the warm season, fewer in the cool season.
