Day 4-8 Convective Outlook

Valid 121200Z - 171200Z

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

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.
