GSP.....
.LONG TERM /SUNDAY THROUGH TUESDAY/... As of 230 PM Wednesday...onset of precip will be Saturday evening, depending on placement of best moisture and timing of shortwave trough the region, which GFS and European models still disagree on. ECMWF still shows a coastal low developing and passing south of our CWA, which introduces a threat of winter wx, though it`s still too far out to pin down any details. GFS leans more into the coastal low setup as of the 12z run. Either case is likely to produce some snow showers in the mountains but if ECMWF guidance pans out then this could extend into the NC Piedmont. In any case, chilly temps will stay in place through Tuesday, before a new upper system approaches from the west. Models diverge greatly as far as timing and dynamics of this system.
