Enjoy some nice mild weather through Saturday afternoon. Colder weather with a few snowy periods appears likely in the Saturday evening through Monday night period. We may see the most significant snow since the 6-12 inches that fell on Dec 15th.
The mild weather Friday and Saturday may be accompanied by some chinook winds in and near the foothills. An all-out windstorm is not expected, but some warm gusty winds may help erode the remaining ice patches that have been around since the 2nd week of December. For mountain areas near and west of the continental divide, Saturday will likely have increasing cloudiness, snow, and wind as the day progresses.
A large, moist storm system from the Pacific will impact the Front Range region in several phases. The first phase Saturday night into Sunday morning is likely to bring significant snow to mountain areas, and some minor snow to the Front Range urban corridor. Then after a lull, the main storm system Sunday night into Monday has the potential to bring widespread snow (in the 6-inch range) throughout the Front Range region.
There is still uncertainty. One model–the European–evolves the storm in a way that would bring the most significant snows to the Front Range region Saturday night, with minor additional snow after that. At this point, I’m leaning toward Sunday night through Monday as the main snowy period for the urban corridor. Either way, be prepared for some changes Saturday evening (earlier in the mountains), and wintry weather into Monday.
