It stands to reason that having snow cover makes a big difference in what air temperatures can be expected. The current stretch of mild weather is thanks to a mostly snowless Iowa. The featured chart displays the monthly average daily high and low temperatures partitioned by the presence of snowcover reported on the same day as the temperatures. There are some caveats to this plot given the timing of temperature and snowcover reports, but the impact is clear. While our current high temperatures are above average, they are not too far from what we'd expect on days without snow cover.
