Updated, 5:05 p.m.: Winter Weather Advisory expires as snow ends. Cold set to take its place. Snow has been tapering off this afternoon and will continue to do so.
At this time we are recording 2.9” total snowfall in Thornton. Some light flurries will continue though through the evening and overnight.
The story now becomes the cold.
Lows tonight will be dropping to the single digits with wind chill temperatures below zero.
Daytime Sunday brings a chance for some snow again but with only light accumulations, if any, expected. There will be little relief from the cold with highs tomorrow in the upper teens, maybe 20, before Sunday night lows drop below zero. We’ll then start a gradual warm-up through the first half of the week.

Original story, 4:18 a.m.: Snow began falling at about 3:00 a.m. in the Thornton area and quickly covered the roads. Soon after the National Weather Service issued a Winter Weather Advisory for the area.
The snowstorms of the past month or so have been entirely underwhelming but the current one does have the potential to be more interesting.
In effect immediately, the advisory runs until 5:00 p.m. Saturday. Total snowfall amounts range from 3 to 6 inches for the Front Range urban corridor. Here in Thornton that amount seems reasonable, perhaps a bit high. Much will depend on how the anticipated snow bands set up.
Areas to the east will see 1 to 3 inches. The high country will enjoy a healthy shot of snow with 4 to 8 inches in the mountain valleys and 8 to 16 inches at upper elevations.
