Temperatures warmed very nicely on Monday with the southern half of Iowa reaching at least 70 degrees and a few spots in southwestern Iowa reaching 80 degrees. Daily record high temperatures were set in Lamoni (76°F), Ottumwa (77°F), Cedar Rapids (75°F) and a few other locations. These temperatures were the warmest to date for the year, so the featured chart checks in on the average first 70+ degree high temperature based on long term climate stations. Each station is labelled with the month/day for the 50th percentile of first day of the year, so approximately the average first date. So we are about one to two weeks ahead of schedule this year. Tuesday will be slightly cooler, but temperatures are expected to warm to similar temperatures on Friday along with a chance of severe storms.
