...POTENT BUT QUICK STORM TO BRING SNOW AND COLD TEMPERATURES THIS
EVENING...

This hazardous weather outlook is for northeast and north central
Colorado.

.DAY ONE...This Afternoon and Tonight

Snow will spread south across the Front Range mountains and
foothills, Urban Corridor, and eastern plains this afternoon and
evening. Heavy snowfall rates, cold temperatures, and gusty winds
to 30 mph will create hazardous driving conditions. These
hazardous conditions will begin around 3pm in the northern
mountains and I-25 corridor north of Fort Collins. Snow rapidly
spreads south into the Denver Metro area by 5pm. Snowfall amounts
of 8 to 14 inches are expected in the higher mountains north of
I-70, with 4 to 8 inches along the urban corridor, and 2 to 5
inches across the eastern plains.

Skies will clear overnight with snow decreasing by midnight and
diminishing towards sunrise. Overnight lows will be cold and
approach record lows in places. Most locations will fall into the
teens by sunrise Tuesday morning.


.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

Snow will end early Tuesday morning, but there could still be icy
roads in spots. Temperatures will also be very cold, falling to
the teens to start the day. There will be another chance of light
snow Wednesday and Wednesday night. Thursday will be warmer with a
slight chance of afternoon showers. Another weak system could
bring light precipitation to the region Friday. Warmer weather
will finally return to the region by the weekend.

.SPOTTER INFORMATION STATEMENT...

Snowfall reports from spotters will be appreciated.
