Dry air leads to stale forecasts

This was a rough set of forecasts for the stable of forecast outlets that we review here at The Weather Blog. Dew points barely got to 5 degrees in Denver, which allowed the clear nights in the Mile High City to become extremely chilly. Overnight lows were only in the teens when there were forecasts as warm as 32 degrees for morning lows each day. There was at least one forecast that was 10 degrees off for every outlet. Things did not go well for meteorologists. The Weather Service had the best forecast, and even that was extremely poor.
Actuals: Monday, High 36, Low 19
Tuesday – High 59, Low 15

Grade: D
