Cold overnight temperatures in the 30s and low 40s in northern Iowa and Minnesota kept the monarchs out of sight for the most part as the new day began in central Iowa. During a one and one-half visit to Neal Smith National Wildlife Refuge in mid-morning, only 8 monarchs were observed. Six of them were near oak trees in the prairie's savanna area. The day was partly cloudy, the temperature was in the high 40s, and a north wind was blowing at 10 miles an hour.
