Although the pattern isn't supporting big snows right now, an approaching cold front will bring a chance for a wintry mix late Wednesday into Thursday morning to Eastern Colorado.
The front arrives Wednesday afternoon from the northeast and this will create upslope flow for all of eastern Colorado. This upslope flow will be enough to support low cloud cover and fog development into the evening hours.
As areas see the clouds lower and fog form there will be a few spots that see freezing drizzle and others that may catch quick snow shower. Neither is likely to offer much of accumulation, but just enough for some areas of ice on the roads into early Thursday morning.
The chance is low for the overall area as this will likely be hit and miss areas of drizzle/snow. Here's a short-range product that shows how very widely scattered the snow/freezing drizzle will be Wednesday evening and overnight:
Right now, most models bring in the clouds but not all generate the precipitation. Watching the atmospheric profiles for Wednesday evening into early Thursday morning indicates the chance for a bit of freezing drizzle, albeit a low chance.
Timing shows the best chance of that wintry precipitation from Wednesday evening through early Thursday morning, odds only in the 20 to 30% range up and down the urban corridor that you see that wintry mix:
Our Gambler Chart data shows the highest potential to see snow lies over the Northern metro area:
You can see just how low the chance is for accumulating snowfall. Other locations that we run the Gamblers Charts for do not produce odds of an inch or more as of Tuesday evening's data.
In all, be aware of the potential for ice Wednesday night/Thursday morning but right now the odds are low. Drier air works in quickly Thursday morning so we don't expect a lasting impact to Thursday.
