Forecast Last Updated at Sunday, January 22, 2017 at 4:27PM
A potent low is moving eastward across the Upstate of South Carolina tonight. Strong storms to our south are robbing some of the northward Gulf moisture transport. As a result, rain totals will be somewhat less than previously expected; however, overall, the forecast story-line remains unchanged. A weak wedge down the east side of the Appalachians keeps temperatures in check and adds fog. Heavier rain will develop tonight with thunder possible. Showers linger Monday and maybe into early Tuesday morning with cooler temperatures. Wind becomes an issue Monday into Tuesday with snowflakes still in play for 5000-foot land late Monday. Colder weather arrives Thursday.

Potent and complex are fit terms to describe the storm system moving across the Southeast today. The longstanding forecast plan for tonight and Monday holds with subtle changes.
After a lull Sunday afternoon, heavier rain arrives tonight with thunder possible. A weak in situ wedge holds temperatures in check and adds fog to the forecast. Big storms to our south are robbing some of the moisture transport--always a potential in this setup. We still expect over 1" of rain tonight.
Showers linger Monday. As the low moves up the Atlantic Coast, gusty NW winds develop bringing cooler temperatures. By late Monday, highest elevations (5000-foot land) could see precipitation change to snow. Light precipitation may linger into early Tuesday with gusty winds continuing. Clouds decrease Tuesday afternoon and winds diminish Tuesday night.
A quick, brief warmup comes Wednesday as the center of mild high pressure moves across the Gulf into Florida.
A front Wednesday night promises an end to the Spring-like temperatures of the last several days. A stray light shower or two is possible Wednesday night into early Thursday. Then snow showers or flurries are possible with falling temperatures. Temperatures remain cold Friday and Saturday with occasional snow showers or flurries still in play.
