Late evening surface analysis shows a cold front located just east of the forecast area over East Tennessee and Alabama with an arctic cold front stretching from Southern Lake Michigan to northwest Arkansas. Regional WSR-88D radar trends show a few returns over eastern Oklahoma and northwest Arkansas with a few METAR observations showing some light precipitation reaching the ground. Some CAMs indicate just enough moisture for a light rain or snow shower or sprinkles or flurries to occur mainly over portions of northeast Arkansas and the Missouri Bootheel over the next few hours with no impacts expected. Confidence is high (>80 %) for much colder air filtering into the Mid-South this weekend with the coldest air arriving Saturday night into Sunday morning as the main upper-level trough rotates through the region.

Another reinforcing cold front Sunday night will prolong the cold temperatures into early next week with lows falling back into the teens for Monday night.
