Wintry week to start the new year

10:40 AM, Monday, January 2, 2017

At 10:30 AM (Monday) the leading edge of a much colder airmass had crossed the Colorado-Wyoming border into Colorado. Temperatures in Front Range region should fall this afternoon and will likely stay in the 20s and colder through the week (maybe teens in Cheyenne). It may take a little longer for the cold air to get to the Colorado Springs area. Nighttime temperatures should drop to around zero on the coldest night (midweek), but likely hover in the single digits and teens in the more persistently cloudy areas. There will be several chances for snow this week, the first tonight and tomorrow looks most focused on the mountains and up in the Cheyenne area.

 

Snow- mountains

It will be a snowy week near and west of the continental divide. By week’s end 1-2 foot totals  may be commonplace in mountain areas. Although areas of clouds and snow are possible all week, the peak times will probably be tonight (especially north of I-70), again on Wednesday in all mountain areas, and again Friday.

 

Snow- Front Range

Snow is likely to organize in long, narrow west-east bands where local amounts may be notably higher than the area-wide average. Although the Denver area received a bunch of snow in these set-ups earlier this season, it appears that the best chance for these west-east snow bands tonight and Tuesday morning will be in Larimer County and southern Wyoming. Several inches could accumulate quickly in the bands. In the Denver-Boulder area odds favor little or no accumulation (there is only a very small chance of a snow band developing). There may be some areas of ice fog or freezing drizzle developing by morning.

 

Another chance for accumulating snow of several inches late Wednesday and Wednesday night is likely to be more widespread. There may be still another chance for accumulating snow Friday.

    Matt: I’m doing a chilly-weather-and-chances-of-snow-in-the-week-ahead story for both the Longmont Times-Call and the Camera to post online later today and for Tuesday’s print editions of both papers. I’ll be tapping much of your report here for that story, as well as updated NWS forecasts through the day.

    Also, Kevin Kaufman from the Camera asked me to check snowpack levels, as well. Would the weather service have that info, or someone else? Any advice about who I could call or where I could find it on the Internet?
