Thornton’s Friday and weekend start warm, to end cold and snowy

Friday, January 19th, 2018 5:07am MST

Quite a contrast in Colorado weather to be seen over the next three days. We will start out with potentially record-setting warmth and close things out with cold and (hopefully) a decent shot of snow.

Friday will be the warmest day of the period. Highs today will top out around 66 degrees. The record high for today’s date is 68 degrees so it is not out of reach. We do expect to see a good bit more cloud cover today though. Tonight, skies remain partly cloudy with lows dipping to near the freezing mark.

Saturday will be a day of transition, starting out nice but then seeing things change as a cold front arrives later in the day. Look for mostly sunny skies above initially with increasing clouds in the afternoon. Temperatures will top out near the 50 degree mark.

A low pressure system will move into southern Colorado late in the day Saturday while a cold front comes in from the north. This will lead to colder temperatures and bring a good chance for precipitation.

Models have not been particularly consistent with the path of the system. However, right now it looks like snow will begin tomorrow evening after dark, perhaps with a bit of rain initially, then snow continues into Sunday morning before tapering off in the afternoon.

The potential will be there for us to see 2 to 5 inches total from this system. It wouldn’t be surprising to see a Winter Weather Advisory issued at some point later today if models continue to keep things on the path they now indicate.

Highs Sunday will stay below freezing.

Looking ahead to next week, right now it appears it will be pretty typical for this time of year with highs near normal and dry conditions.

Have a great weekend and keep an eye on the changing weather conditions. Our Winter Weather Briefing Page is a great spot to watch.
