A shallow cold air mass is banked up against the lower foothills and it will probably be Saturday before it’s pushed east. During this afternoon locations such as Nederland and Idaho Springs basked in the 40s while Denver and Boulder were 20 degrees colder with low stratus. The cold air didn’t fully get over the Palmer Divide, so Colorado Springs is not quite as cold as places to the north.
During the night and into Thursday there may be some areas of fog, light freezing drizzle, and possible some light snow grains in and along the lower foothills mainly north of the Palmer Divide. Amounts should be quite light, but it doesn’t take much freezing drizzle to make for some icy surfaces. The overcast may thin a bit by Friday, but it will likely be Saturday before westerly winds bring a fresher air mass.
