Following a warm start to the week, big changes with snow are in store for Denver by Wednesday night.
A powerful cold front will plow through the Denver area on Wednesday night, bringing rain followed by snow as the low plummets into the upper 20s.
"While the snow will only fall over a window of about six hours after the cold air arrives, the rapid drop in temperature to near freezing could support accumulation on some road surfaces," AccuWeather.com Meteorologist Bill Deger said.
In Denver, a light coating of snow will be possible. The heaviest snow, 3-6 inches, may fall farther north across the northern Colorado Rockies, southeastern Wyoming and western Nebraska.
