URGENT - WINTER WEATHER MESSAGE
National Weather Service Denver CO
1209 PM MST Fri Nov 17 2017

...SNOW TO CONTINUE 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 this afternoon and
evening. 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.
