It’s been over six months now, but winter weather is finally set to return to the Front Range this weekend as the coldest air of the season shows up alongside several inches of fluffy snow.

Change is on the way! Unseasonably warm temperatures will continue across the Front Range for a few more days leading up to a significant pattern shift later this week.  A series of cold fronts will impact the area in the days to come, knocking our high temperatures from the 80s on Monday into the 40s by Friday, though precipitation looks scant during this timeframe.

There’s a better chance of setting record high temperatures this week than there will be to see any kind of precipitation. We are watching a couple of cold fronts, but they will be the dry variety with temperatures not even dropping below normal on their backside. Upper-level ridging will continue to push in from the West Coast for the weekend keeping things pleasant and dry through at least Sunday for our area. As you might imagine, there’s no chance of snow or additional sub-freezing temperatures in the pipeline.
