snow. the good news is that the system is a fast mover. look how quickly it moves to the east of us. there is another one following on wednesday in into thursday. this one is out of here by midmorning. it will be colder. not as cold as the east of us where we are on the fringe of the arctic air mass. we have clouds settling in and snow developing in the northern and central mountains. the snow moves into debt -- into denver around 6:30 in the morning. it will be done by 10:30 in the morning. we will have clear skies in the afternoon and the chilly day. we start off with 20s and the lower elevations and teens in the high country. it will be cold for the western half of the state and cooler for denver and the front range. we are just on the western edge of what could be a very cold arctic outbreak. even with a little bit of snow during the morning drive, we are doing pretty well. the forecast is cloudy with snow developing after about 3:00 in the morning. we're not expecting more than an inch of accumulation. mid-30s by the afternoon with sunshine.
