A cold front is moving through Cheyenne now, and will pass through Denver
in the early evening. 40-60 mph gusts behind the front with localized
blowing dust for a few hours.
Snow will develop north of Denver and in the northern mountains in the
early morning hours, then along Interstate 70 around rush hour, and further
south during the morning.
During most of this event, there will be rain or snow that melts for
elevations below 5000 feet. Below 7000 feet, snow is generally expected to
melt on the roads. Temperatures at lower elevations will be a little above
freezing during the day Tuesday, then in the upper 20s to around 30 Tuesday
night. This may lead to minor snow accumulations on grassy areas on the
plains Tuesday night.
In the mountains and higher foothills, there will still be substantial
melting during the day Tuesday, but it will be cold Tuesday night so there
is a better chance of some slush, snow, or ice on the roads. The main
threat is during periods of heavy snow on the east side of the Front Range
Tuesday evening.
Snow will end north of Denver Wednesday morning, and midday/early afternoon
in areas along and south of I-70.
While most of the snow is expected to melt on the roads, there may be
problems from accumulations on tree branches leading to falling limbs and
power outages if the snow accumulations are on the higher end of our
expected ranges.
Expected snow totals (on grassy areas):
Front Range mountains and foothills: 8-18", with higher amounts in
backcountry areas
Douglas County/Monument Hill and Park County: 6-12"
Front Range cities from Denver to Fort Collins and I-70 east to Limon: 3-7"
Northeast plains: 1-4"
