Another storm system will bring, you guess it, more rain to the Carolinas this weekend; however, the major story will be the cold temperatures that arrive following the front passage.
Ahead of the system, temperatures will remain above average. Some areas made reach the low to mid 60s for highs on Friday before clouds return Friday night and Saturday ahead of the system.
This system has plenty of energy to work with and will be able to pull moisture northward from the Gulf of Mexico. The 500 mb analysis shows the system tracking through the middle of the country on Saturday before moving northward into New England on Sunday.
While some areas north and west of the upper level disturbance will be seeing a major snow storm, we will be receiving mostly rain from the system. The good news is models show the rain moving in during the overnight hours Saturday.
The system will be pulling away on Sunday morning across the mountains, foothills, and western piedmont; however, mountain locations will transition to snow as colder air moves in. It will take until the afternoon hours Sunday for eastern locations to dry out.
When all is said and done, between a half of an inch to one inch of precipitation is expected across much of the Carolinas. The mountains, foothills, and western piedmont are expected to see up to an inch and a half inches of precipitation before the moisture pulls away.
One the backside of the front, cold temperatures will invade the southeast United States. This will be some of the coldest air of the season, with temperatures ranging 10-20 degrees below average. Overnight lows are expected to be in the teens on Monday and Tuesday morning in the mountains, foothills and piedmont.
In the mountains, snow is expected Sunday afternoon and evening. While it is still too early to determine how much snow is expected, upslope favored locations may see up to 3-6 inches of snow before the northwest snow tapers. The system finally pulls away from the mountains Sunday night with sunny skies returning Monday.
