The first major snow of the season for the west and central mountains looks to arrive to Colorado early next week!

Long-term forecast models have consistently shown a deep, long wave trough setting up over the west Sunday into Tuesday. This would be a classic pattern to draw cold air and moisture over the Rocky mountains, resulting in healthy mountain snow.

It’s far too early for exact town and city totals, but early model forecasts paint over swaths of 8 or more inches through the Continental Divide and well over 12 inches for the San Juans!

While this is good news to drought stricken Colorado, there’s still a pretty big caveat to consider. Weather model forecasts over five days are often wrong and need to be taken with a large grain of salt.

Even though there is quite a bit of uncertainty this far out, there are a few encouraging signs in this forecast. For one, we’ve seen good agreement in the pattern from a few different models. The other big thing is the same extended forecast showing up over the last couple of days, meaning the models seem pretty locked on to the cold and the snow.
