DENVER -- It may be warm now, but get ready for another dramatic change in weather in just a couple of days, Denver. 

A cold front will sweep across the state by early Thursday, bringing with it one-to-three inches of snow to the Mile High City and falling temperatures as winter season officially begins. 

In the mountains, this front should drop four-to-eight inches of snow, with a few lucky spots in the northern and central mountains getting closer to ten inches.  

Highs on Thursday will be in the 30s to near 40 degrees, but temperatures by the afternoon will only be in the low to mid 20s. Temperatures will moderate up a few degrees on Friday, but then plummet for the weekend as a second cold front sweeps across Colorado on Saturday. 

Mike Nelson will issue a First Alert Action Day beginning on Wednesday evening at 10 p.m. and lasting through Thursday evening at 10 p.m.

By the way, on Wednesday, Dec. 20, Denver7 will be featuring our "HOLIDAY HOTLINE" from 4 p.m. until 6:30 p.m. Meteorologists from Metro State will be in the studio to provide free, custom weather forecasts to help you with your Christmas travel plans.
