After another unseasonably warm day on Monday, cooler weather will return to Colorado and southeastern Wyoming Tuesday and Wednesday. There is even a good chance for a minor snowfall from the south Denver suburbs and southward late Tuesday, and a smaller chance north of Denver.
The cold front should slide through the area by Tuesday morning making it about 30 degrees colder than Monday. Intermittent precipitation on Tuesday will likely be rain in low elevation areas at first and snow later in the day. But snow accumulations from Denver north will likely be minor, if any. The best chance of accumulation is in the foothills and mountains. South of Denver, including the south suburbs, the chance for 1-4 inches is greater. Local areas of over six inches will probably be observed in the Palmer Divide region and mountain/foothills areas south of Denver.
Halloween evening is likely to by chilly, but drier.
