Partly sunny skies yielded little surface warming and the Greenville Municipal AP only recorded an afternoon maximum of 42 degrees. During the latest hour of the day, sleet began falling near Salem. Over-running moisture, associated with a feature moving northeast from the Gulf of Mexico, brought a wintry mix and cold rains for Tuesday. At 3:15 a.m., Greenville reported freezing rain and sleet.
