Our first significant cold front of the 2017 fall season arrives late tonight into early Tuesday morning. Latest indications are that the front will arrive between midnight to 3 a.m. CDT. There is a 30-40% chance for scattered showers and/or brief thunderstorms as the cold front pushes through the area generating lift (rising air). Behind the frontal boundary, a significantly cooler and drier air mass will invade the area from the north on breezy/gusty north winds. Winds will gust between 25-30 mph well into Tuesday morning. This same storm system is producing snow across Colorado today. Denver is currently a winter wonderland with between 4-6 inches of snowfall accumulation already being reported and it's still snowing. This is Denver's earliest reported snowfall in the past 5 years.
