Line graph showing cooler-than-average conditions in early spring and warmer conditions in later spring

Image caption

This line graph shows how daily temperatures in Baudette, Minnesota, were below average on many days in mid-March, contributing to a 5-day delay in the emergence of the season's first leaves. But a significant warm up in April brought flowers out 6 days early. NOAA Climate.gov graph, based on data from NOAA Northeast Regional Climate Center and the U.S. National Phenology Network.
