FRIDAY: Friday will be the warmest day until late next week as we reach the upper 20s north of I-70 and low to mid 30s south with southeast winds at 5-10 mph. Clouds will thicken as a cold front moves through Friday night. Snow flurries or patchy freezing drizzle are possible north of I-70 Friday night as arctic air moves in.

Some snow flurries are possible but at this time, no measurable snow is expected.
