Wow what a forecast change in the last 24 hours. I will say that our weather team was definitely talking about the chance of snow for Saturday, but now accumulations look possible! As an upper level system swings through post-cold front, we'll get a window of opportunity for some light and even brief moderate-heavy snow. Here's how is plays out as it looks now:
6am-9am: Sleet and light snow will be found in parts of the western Upstate, mountains and GA. No accumulations expected in lower elevations at this pt.
9am-Noon: Snow will become a little heavier in spots. Could see accumulation on grassy surfaces. This would be when Pickens, Easley, Walhalla, Anderson, Greenville see snow pick up, then during the afternoon it will shift eastward.
Noon-3pm: This looks like the best time-frame to see accumulating snow for the Upstate. This would be from Spartanburg and east as it looks now. 1-2 inches could accumulate during the afternoon for places like Gaffney, Union, Laurens, even the city of Spartanburg and surrounding areas. Roads should just be wet during the afternoon.
3pm-7pm: Snow will transition out. We'll be watching for potential black ice on the roads late night Saturday night.
This timing could EASILY speed up, as often happens with winter systems around here! But this is my best educated guess at this point :)
THe mountains won't get high snow totals out of this, but we'll see around 2-4 inches in the higher elevation spots.
Sunday will be sunny with highs in the 40s. Snow will melt by afternoon wherever it's still on the ground.
