There are at least 4 different waves of rain the next week. Today/tonight, Saturday, maybe even Sunday, Tuesday then later next week another strong low. Rays weather posted this graphic with 6 to 8 inches of rain over most of SC and some of NC.
You're not wrong about people not wanting to talk about rain in winter but there will be severe weather. There is even a slight risk today for part of the upstate. We will be looking at some strong lows going up the TN Valley and be in the warmer SE quadrant, especially piedmont and coastal plain areas.
