Series of fronts arrive with much colder air

Cold fronts bookend the week in Knoxville, with clouds thickening overnight and a few mountain flurries as temperatures drop into the low to mid 20s by Sunday morning on a northwest breeze. Sunday stays frigid, barely reaching the mid 30s and feeling like the 20s despite sunshine. Monday remains clear and cold, setting up the coldest morning Tuesday, with teens area wide and highs near 35. Another front pushes in Thursday bringing rain, with a mix of cold rain and snow showers possible in higher elevations late Wednesday into Thursday, before temperatures rebound into the low 40s.
