Weather Story |
NWS Denver/Boulder, CO
For today and tonight:
Areas of light snow will continue over the mountains this
afternoon and increase tonight. Accumulations of up to 4 inches
are possible in the higher mountains by Sunday morning, with
lighter amounts in north and Middle Parks. On the plains, it
will be mostly cloudy with temperatures similar to Fridays.
For Sunday through Friday:
Snowfall is expected to pick up in the mountains of northern
Colorado Sunday afternoon and become quite heavy Sunday night.
Areas up around the Eisenhower Tunnel, the high mountain passes
and northwest facing slopes above 9000 feet could see snowfall
rates of 2 to 3 inches per hour at times, together with
sustained northwest winds of 25 to 40 mph and gusts to around 70
mph. The heavy snowfall and strong winds will likely produce
whiteout conditions creating treacherous driving conditions for
high country travelers particularly Sunday night and Monday
morning. Areas above timberline and west facing slopes above 9000
feet could see 12 to 24 inches of snow pile up by Monday evening.
East facing slopes and high valley locations are likely to see
lighter snow totals.
Meanwhile there is a slight chance of snow on the high plains
Sunday night and a better chance for snow on Monday and Monday
evening following the passage of a cold front. Snow accumulation
on the plains should be light and only scattered in coverage.
There is another opportunity for snow Christmas Day through
Friday with another storm system possibly moving down from the
Pacific northwest. There is much uncertainty in the models as to
when, where and how much snow will fall. Therefore, stay tune
for later updates.
Spotter activation will not be needed today or tonight.
