SC Winter Weather Update–12/8/18 AM

By December 8, 2018Blog

Attached is a recent one pager from NWS GSP as well as their 5am Update.  Below is a forecast from the SC State Climatologist Office.

Good Morning,

No change to the synoptic situation for Sunday’s winter event; just an orderly rearranging of the deck chairs with the iceberg dead ahead.  Snow and ice totals have crept upwards overnight. Rain transitions to snow after midnight tonight. Along the I-85 corridor snow changes over to a mix of sleet and freezing rain after 2 PM then back to snow after sunset before tapering off to just light liquid drizzle late Sunday morning. Heaviest precipitation events will be early Sunday morning until late afternoon Sunday.

The latest forecast snow accumulation amounts:  1-4 inches of snow along I-85 Anderson to Greenville, 4-8 inches of snow from Greenville to northern York county. Snow amounts 8-12+ inches along the SC-NC border. Hard-pressed to make a case for an frozen accumulation across the northern Midlands and points south; just a few rogue flakes north towards I-20.

Ice accretion totals have crept up ominously. Generally less than a 0.10 inches across the Upstate. The ominous part: Greater than 0.10 inches Greenville to Rock Hill in a strip north and south of I-85 with ice amounts 0.25 inches to 0.30 inches in a wide swath from Greenville to Spartanburg  either side of the I-85 interstate highway luge run.  The Upstate Monday morning commute could quite sporty.

Temperatures dip below freezing again Monday night.
