URGENT - WINTER WEATHER MESSAGE
National Weather Service Denver CO
353 AM MST Fri Nov 17 2017

...SNOW TO INCREASE OVER THE MOUNTAINS...

.A Pacific jet stream and moisture plume will combine to produce
accumulating snowfall over the northern Colorado mountains today
through this evening. Snow intensity is expected to increase
sharply from north to south this afternoon, reaching the I-70
Mountain Corridor by late afternoon or early evening as a strong
cold front arrives. Travel conditions will 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 tonight, with drier conditions
expected by Saturday.

On the plains, scattered rain and snow showers will likely
develop by early evening, behind the passage of a strong cold
front. Any snow accumulation on the plains is expected to be
light.
