A Cold March
It have been a colder than normal March so far and month coming to an end shortly. All of the high temperatures this month (so far) have not not reached the average high for the day or above at Waterloo and Dubuque. Cedar Rapids only reached the goal one day and Iowa City two days. An interesting tidbit about the data for Waterloo. It shows there has only been two other years (1915 & 1960) that the high temperatures have not reached the average high for any day in March.
