URGENT - WINTER WEATHER MESSAGE
National Weather Service Denver/Boulder CO
1026 PM MDT Fri Oct 23 2020

...WINTER SNOW AND COLD HEADED FOR COLORADO...

.A storm system will drop southward across Colorado starting
Saturday night, with much colder temperatures and accumulating
snowfall. Snow will first develop over the northern border area
late Saturday evening, and then spread slowly southward into the
I-70 late Saturday night or Sunday morning. The heaviest snow is
expected to fall on Sunday, before tapering off Sunday night into
Monday morning.

Temperatures will be very cold, with highs only in the lower to
mid 20s on Sunday, and then single digit lows Sunday night.

The colder temperatures and snow will result in snow covered
roads, and slick travel conditions. If you are planning to
travel, be prepared for slower than normal travel conditions, and
use extra time to reach your destination safely.  Also, be
prepared for the sharp change in temperatures and dress warmly in
several layers of clothing.
