After gusty winds reached 75 mph on Monday, Boulder could see 6 to 12 inches of snow -- more possible in the foothills -- and icy temperatures the rest of the week.

The day's winds and mild temperatures, which were a precursor to the cold front expected to reach Boulder this morning, caused downed wires, power outages and flying debris.

"Gusty winds will gradually abate late (Monday night), but then that's replaced with the arctic air and that's going to be here for many days," National Weather Service meteorologist David Barjenbruch said.

The cold front is dumping snow and spreading cold temperatures across much of the northwestern United States, Barjenbruch said.

The National Weather Service forecasts a chance of rain before 11 a.m. Tuesday in Boulder, and then a chance of snow as temperatures fall to around 26 in the afternoon.

This evening, the wind chill could drop to as low as minus 5, according to the forecast, with a 90 percent chance of precipitation.


On Wednesday, there's an 80 percent chance of snow with a high near 13 and wind chill as low as minus 8. Temperatures are expected to stay in the single digits through Friday.

"Right now we're looking at 6 to 12 inches for Boulder, with heavier amounts up into the foothills," said National Weather Service meteorologist Bernie Meier.

The cold front expected this week is traveling south from Siberia and across Alaska and Canada.

Temperatures should drop below zero Wednesday and Thursday nights, Meier said.

Meier said untreated roads will be snow-covered and slippery because it will be too cold for the snow to melt.

The lowest recorded temperature for Dec. 3 in Boulder occurred in 1919 at minus 2, according to data provided by the National Oceanic and Atmospheric Administration.

Monday's weather was all about the wind.

The National Center for Atmospheric Research recorded a peak gust of 75.4 mph at its Mesa Lab just before 1 p.m..

Boulder police dispatchers reported multiple instances of downed wires and malfunctioning traffic lights, and Xcel Energy customers experienced several outages, including one affecting nearly 800 customers near 28th Street and Iris Avenue.

Many social media users posted photos wind damage, such as smashed patio furniture toppled by the winds. At the University of Colorado, debris crashed through a window at the Armory Building on campus.
