DENVER -- A winter weather system will move into the Denver metro area on Wednesday, bringing with it cold temperatures and snowfall accumulation totals that will vary depending on location.
Interstate 25 appears to be the dividing line between the lighter accumulations and the really heavy amounts of snow.
A few light rain showers are possible early in the afternoon, but by 3 p.m. to 4 p.m., it should be all snow, with the heaviest rates of 1-2 inches per hour possible mainly from 4-11 p.m.
From downtown Denver eastward, totals might only be in the 1-4-inch range. But west of I-25, accumulations could be more in the 6-10-inch range, with totals in the 8-12-inch range in the foothills.
A winter weather advisory will go into effect at 3 p.m. and last until 6 a.m. Thursday for Longmont, Boulder, Denver, Highlands Ranch and Castle Rock.
A winter storm warning will go into effect at 2 p.m. and last until 11 a.m. Thursday for the foothills between 6,000 and 9,000 feet, including Estes Park, Nederland, Idaho Springs, Georgetown and Evergreen.

With the snow will come falling temperatures into the 20s. Highs will stay in the 20s on Thursday through Sunday. Another chance of snow is possible this weekend, mainly Sunday night, then another shot on Tuesday.
Meanwhile, after a long stretch over the weekend, the Colorado Department of Transportation and Denver Public Works crews got a bit of a break Tuesday. But by the time the storm hits Wednesday afternoon, they'll be on the clock.
CDOT and city crews will be working around the clock to try to keep roads clear during the storm. Up to 70 plows in Denver and up to 100 CDOT crews will hit the roads Wednesday night into Thursday morning.
