ACUS48 KWNS 090918 SWOD48 SPC AC 090917 Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0317 AM CST Sat Dec 09 2023 Valid 121200Z - 171200Z ...DISCUSSION... Severe potential appears likely to remain negligible for several days in the wake of this weekend's cold front progressing across the Gulf Coast and the Atlantic Seaboard. Above-average agreement exists with the establishment of a surface anticyclone over the southern Appalachians vicinity on D3 into D4, and remaining anchored in this region through at least D7. This will yield predominant easterly surface winds over the Gulf and FL Peninsula, with gradual airmass modification. Next weekend, deterministic 00Z ECMWF, GFS, and CMC suggest potential for eastern Gulf or South Atlantic Coast cyclogenesis. This may occur in response to an upper low, that initially develops over the Southwest mid-week, being kicked east and subsequently amplifying towards the Deep South. Very large spread in timing and track, in addition to only a minority of ECMWF ensemble/GEFS members supporting such a scenario renders low confidence in predictability for the D8-10 time frame. ..Grams.. 12/09/2023
