HIDE Special Weather Statement issued March 21 at 5:15AM EDT by NWS Greenville-Spartanburg
...ACCUMULATING NORTHWEST FLOW SNOWFALL POSSIBLE ACROSS HIGHER
ELEVATIONS LATE THIS AFTERNOON THROUGH TONIGHT...
A compact but cold upper level low and associated cold front will
support snow showers initially limited to elevations above 5000 feet
this afternoon before colder air behind the front lowers snow
levels to between 3000 to 4000 feet later this evening and
possibly to the valley floor tonight. Snowfall amounts of 1-2
inches are possible mainly above 5000 feet, except as low as 4000
feet for upslope areas near the Tennessee border. The potential
exists for dangerous driving conditions across high mountain roads
due to the combination of snow and gusty northwest winds.
