The past three weeks have seen plenty of bouts with below zero weather. The featured time series is of hourly temperatures from the Ames Airport since late last year. The blue stripe represent the climatology range between the daily high and low temperature. The chart shows seven events during this period with the temperature below zero. The good news for those that don't like this very cold weather is that warmer temperatures are in the immediate near term forecast with highs even well above freezing later this week!
