DENVER – The last day of fall will be unseasonably warm for the Mile High City.

Highs will climb into the mid 50s with gray skies because of a mountain wave cloud. It will be windy at times, especially in the foothills. Tuesday night will be mostly cloudy with lows in the mid 20s.

A cold front arrives Wednesday, bringing light snow for the mountains and cooler temperatures for the Front Range.

Early in the morning, there is a small chance for some light snow with little to no accumulation. Temperatures will be cooler in the afternoon.
