There is a cold front moving down the plains and pushing moisture upslope into the Front Range. Expect snow to develop this afternoon east of the Continental Divide. The upslope stays shallow, and the intense snowfall will not spill very far west of the Divide. Snow showers develop over the rest of the Northern Mountains this evening. By midnight, the snow showers should spread to the Central and Southern Mountains. Expect an inch or few of snow by Tuesday morning for most mountain areas. Snowfall quickly fades after sunrise on Tuesday. Air temperatures will start cool on Tuesday, but may warm up quickly under sunny skies. Clouds move back in on Tuesday night. Unsettled, showery weather develops Wednesday and could continue through the end of the week.
