The freezing drizzle has been limited to areas in and near the foothills of Boulder, Jefferson and Douglas Counties, although some icy conditions have also been reported to the west of I-25 in the Denver area. The freezing drizzle will continue adding to any icy surfaces for the next couple hours. Motorists should give themselves extra travel time for this morning's commute.
