Can you be specific about WYFF? Currently in TN but heading back to southern upstate today. .

Oh come on, please do. .

Can you share SC totals? .

How about that....upstate Mack special .

NWS Columbia SC .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... The main concern during the medium-range period is a possibility of a wintry precipitation mix. Surface high pressure will extend from the Midwest into the mid- Atlantic region over the weekend. this ridge of high pressure will direct a cold northerly flow into the forecast area. Low pressure along the western and central Gulf Coast Saturday will move northeast and be off the Southeast Coast Sunday and Monday. The GFS and ECMWF and most of the ensemble guidance exhibit this general pattern but with enough inconsistency in the surface and upper features for a low confidence precipitation-type forecast. Moisture ahead of the Gulf Coast system will be moving into the forecast area Friday night. The GFS and ECMWF show the significant lift remaining west of the area through the night. The airmass will be initially dry and it may take most of the night to saturate, so have continued a chance for rain late Friday night. Forecast soundings were consistent indicating liquid precipitation. The moisture should become deep Saturday ahead of the Gulf system. Isentropic lift will also be on the increase. The GFS and ECMWF MOS have trended higher with likely or categorical pops. The moisture will likely remain high through Monday. However, there may be a mid-level dry slot which the models have shown affecting the area mainly Sunday and Sunday night which further complicates the forecast. The deterministic GFS and ECMWF forecast soundings have generally indicated liquid precipitation throughout the area Saturday and Saturday night except the soundings indicate a rain and sleet mix in the extreme north part Saturday night into Sunday then some warming as the low nears the area. More cooling will likely occur as the low shifts eastward and the cold upper system moves into the area. We have forecasted a rain and snow mix in the northwest part Sunday night and Monday. A considerable number of GFS and ECMWF ensemble members support periods of frozen precipitation in the north. Most but not all members have liquid precipitation in the south. There have been differences with respect to the development of a mid-level cut- off low and in its position. A farther south track of a strong upper system would indicate a threat of winter precipitation even in the Central Savannah River Area. The threat in the south should hold off longer and depend on the upper system Monday. Based on the ensemble guidance at this time, we believe the threat of significant winter precipitation during the Saturday night to Monday time frame is about 40 percent in Lancaster County in the north to just 5 to 10 percent farther south in the Columbia to Augusta areas. High temperatures will be in the 40s Saturday through Monday. The storm system is expected to lift out of the area Monday night with dry conditions returning Tuesday. Highs Tuesday will moderate into the upper 40s and 50s. .

How’s it looking for our neck of the woods? .

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. .
