Winter Storm Warning

URGENT - WINTER WEATHER MESSAGE

...SNOW RETURNS TO THE MOUNTAINS...

.A Pacific jet stream and moisture plume will combine to produce accumulating snowfall over the northern Colorado mountains later tonight through Friday night. Snow will begin to develop towards midnight, and become more widespread during the day on Friday. Snow intensity is expected to increase sharply from north to south Friday afternoon, reaching the I-70 Mountain Corridor by early Friday evening as a strong cold front arrives.

Travel conditions are expected to deteriorate rapidly during this time, with snow levels quickly dropping to valley floors. Blowing snow may produce poor visibilities, especially over the high mountain passes. The heavy snow will decrease from northwest to southeast late Friday night, with drier conditions expected by Saturday.

On the plains, scattered rain and snow showers will likely develop behind the strong cold front late Friday afternoon and evening, but any snow accumulation on the plains is expected to be light.
