DENVER -- The biggest snowfall of the season moved into Denver and the Front Range on Saturday night.
The storm system will bring big snowfall totals and impacts to travel.
Snow began falling in western Colorado and in the northeast mountains earlier Saturday and will make its way to Denver and the Interstate 25 corridor between 10 p.m. and 1 a.m.
It will most likely start in Denver, the Front Range and Plains as freezing drizzle before changing over to snow early Sunday morning.
Freezing drizzle will create a layer of ice underneath snow on the roadways, making roads slick through the day on Sunday.
Snow showers will stick around for most of the day in the mountains, Plains and on the I-25 corridor, and will be heavy at times.
Winds will be gusty, especially on the Plains, causing reduced visibility and making travel difficult at times. Travel is not advised.
Snow will taper off from west to east on Sunday night, ending on the I-25 corridor and mountains by 11 p.m. and clearing out of the Plains by 6 a.m. Monday.
Totals will reach 4-8 inches for the Front Range, including Castle Rock, Denver and Fort Collins.
The central mountains will see 6-14 inches of snow with the northern mountains expecting 5-12 inches.
The northeast Plains will see 5-10 inches of snow with southern Colorado and the southeast Plains picking up 1-4 inches.
The last time Denver saw more than 4 inches of snow from one storm was on Dec. 16, 2016.
A winter storm warning is in effect for the Denver metro area and northeast Plains until 5 p.m. Sunday. A winter weather advisory is in effect for the mountains until 2 p.m. Sunday.
High temperatures will only reach the 20s in most spots on Sunday.
It is possible there will be slick roadways for the Monday morning commute with lows in the teens.
Denver will dry out for the rest of the week with highs in the 30s and 40s each day. There is a slight chance for some flurries on Friday.
