...THERE IS A SLGT RISK OF SVR TSTMS ALONG A SMALL PART OF THE GULF
COAST LATER THIS EVENING AND TONIGHT...
...MS DELTA REGION EWD ACROSS THE FL PANHANDLE...
MORNING MODELS ARE IN AGREEMENT IN DEEPENING A SURFACE LOW NNEWD
ACROSS FAR SERN LA EARLY THIS EVENING AND INTO W-CENTRAL AL
OVERNIGHT...AS LARGE UPPER LOW EJECTS QUICKLY NNEWD INTO THE MID
SOUTH BY TONIGHT. OVERALL SETUP WILL BECOME FAVORABLE FOR INLAND
PUSH OF RICHER MARINE AIR SOUTHEAST OF THE SURFACE LOW...MAINLY NEAR
THE GULF COAST FROM FAR SERN LA INTO THE FL PANHANDLE. THOUGH
SURFACE DEW POINTS AOA 60F WILL LIFT QUICKLY NWD ACROSS THIS
REGION...WARMING WILL ALSO BE PRONOUNCED AROUND 850 MB WITHIN LOW
LEVEL THERMAL RIDGE. FORECAST SOUNDINGS INDICATE THIS WILL LIKELY
CAP SURFACE-BASED PARCELS AWAY FROM WARMER SURFACE TEMPERATURES
NEARER THE COAST. SHEAR WILL STEADILY INCREASE THROUGH THE PERIOD
AS SSWLY MID/UPPER LEVEL WINDS STRENGTHEN ALONG WRN PERIPHERY OF
ASSOCIATED JET...AND SUPPORT ORGANIZED/ROTATING STORMS. SHOULD
STORMS ROOT INTO THE BOUNDARY LAYER LATER THIS EVENING AND
OVERNIGHT...SEVERE THREAT WILL INCREASE. PRIMARY THREAT WILL BE
FROM AN ISOLATED TORNADO OR TWO...ALONG WITH A DAMAGING WIND
POTENTIAL.
