After a cloudy Sunday morning, the sun came out for the afternoon and evening, allowing temperatures to warm near the 40° mark for most. A bit of low-level cloud cover has tried to develop across Southwestern Wisconsin late into the evening but will dissipate as the night goes on. This clearing will allow temperatures to fall into the mid and low 20s for most. Those who remain under clearing all night may be more likely to see the low 20s, given the current dew points in that range.
