Less than a week ago, much of the area was digging out of an early spring snowstorm, which brought 6 to 9 inches snowfall to areas of eastern South Dakota, Southwest Minnesota, and Northwest Iowa. This resulted in highs in the 30s and 40s...more typical of 4 to 6 weeks earlier in the year. Now, after a quick warmup and melting of snow, temperatures surged as much as 40 to 50 degrees warmer than those highs from a week ago this afternoon, ahead of a frontal zone moving southeast across the area.

Here are the high temperatures for locations on the map above, as well as some facts about some of these very warm temperatures...
