3 Month Temperature Outlook

Here's the NOAA 3-month temperature probability outlook valid for December, January and February. The warmer colors represent a greater chance for above normal temps while cooler colors show the probability of below normal temps. This pattern, as you might surmise from the image, favors a winter-long period of cold fronts backing into the front range from the northeast.

Does that mean a lot of upslope snow as well?

I would not interpret this to mean "a lot of upslope snow".... Strong upslope snow storms typically develop when we have a deep, slower moving, low pressure system propagating across the southern part of Colorado. Those systems can tap deep layers of moisture on the southeastern plains and funnel it up to the front range. This 3-month probability temperature outlook is simply guidance. It is, however, the layout of the colder air in the upper midwest that tells the story. Any arctic airmass that sends cold air south into Canada has the potential to perturb the cold air on the northern plains sending a pulse of cold air into NE Colorado

Don't want to stretch this too far, but its at least possible that cold weather flyers "may" have more opportunities for cold front soaring at Lookout, than what might otherwise happen in a "normal" year.

Rich,

Seems like your predictions are accurate... How do we find information about long term WX forecast? As always we appreciate your input.

Cheers,
