  1. NWS GSP .LONG TERM /FRIDAY THROUGH MONDAY/... As of 340 AM Tuesday: Confidence continues to grow that a significant winter storm will impact portions of the forecast area beginning sometime Saturday and continuing in earnest Sunday and possibly evening Monday. However, the details this far out are still sketchy at best as any small changes in the track or strength of the storm system or parent sfc high pressure to the north could make the different be mostly a cold rain or significant ice/snow. The greatest confidence in significant ice/snow accumulations continues to be across the mountains and east facing foothills where WPC continues to advertise a 50-70 percent chance of winter storm warning level ice/snow accumulations. The latest forecast blends the EC and GFS, leaning towards the slower EC in line with neighboring offices and WPC. Now for the forecast details as they stand now. Zonal flow will continue into the extended time frame Friday with surface high pressure continue to exert its influence across the region into Saturday. The net result will be fair skies with reinforcing cool and dry air Friday night as air damming or a wedge sets up east of the mountains Friday night, which will likely persist through the weekend. This will set the stage for the potentially significant winter storm as wet bulb temperatures fall into the mid 20s to mid 30s across the FA Saturday. An amplified upper trough will push through the southern Plains states into the Deep South Friday into Saturday with an attendant sfc low pressure system riding the Gulf of Mexico coastline before moving off the Southeast coastline Sunday. The CAD and increasing clouds and precip Saturday into Sunday will lock in cold temps with lows only in the 20s to 30s and highs only in the 30s to low 40s this weekend. This scenario looks to favor mostly wintry precipitation and possibly mostly snow across the mountains with a mix bag of precipitation across the NC Piedmont with some combination of rain or mixed precipitation further south into the Upstate of SC and northeast GA. While its too early to get into precipitation type details, wouldn`t be surprised to see more wintry look to precip across the region near onset and towards the end with more rain or ice in between when the storm is closest and pushes warmer air at mid levels (aka warm nose) into the region. The heaviest precip currently looks to take place Saturday night into Sunday. In addition to the wintry this weekend, model guidance shows some potential for significant snow on the backside of the storm late Sunday into Monday. Now is the time to put your winter weather plan together to be prepared for this and future potential winter storms. .
  2. Orangeburg, no apology needed with a lot of us here. Many feel the same excitement as you, they are just not posting it. .
