An almost stationary boundary across South Carolina was the focus of heavy rains that fell Monday into Friday. Afternoon temperatures early in the week ranged from the 40's on the northern side of the boundary into the 60's and 70's on the southern side. Flood warnings and advisories were issued for most rivers. Thursday's heavy rains caused numerous secondary roads to become impassable. Cold air, drawn into passing low pressure, produced light snows across the upstate Thursday afternoon. Slow clearing and gusting winds were observed late Friday. Sunny weather returned on Saturday and Sunday with temperatures warming back into the 70's and lower 80's. The average statewide temperature for the period was eight degrees below normal.
