It was actually rather warm in Janesville, thanks mostly to a tidy little cloud blanket the city saw each of the past two days. Most expected a cool down after the snow showers ended on Monday, but that was not to be. Accuweather was the warmest with their forecast, especially on the lows, and ended up winning the forecast.
Actuals: Monday, snow reported but not measured, High 39, Low 28
Tuesday, High 30, Low 23
