...15 UTC UPDATE...

...SERN US/CENTRAL GULF COAST TO TX/NM...

THE THREAT OF EXCESSIVE RAIN REMAINS POSSIBLE TODAY/TONIGHT FROM
PARTS OF THE SOUTHEAST THROUGH THE CENTRAL GULF COAST STATES AND
ACROSS TX INTO NM. A FRONTAL ZONE AND LEAD MESO-BOUNDARIES FROM
LINGERING ONGOING CONVECTION ARE SAGGING SOUTHWARD WELL IN THE
WAKE OF CINDY AND WILL INTERACT WITH POOLED MOISTURE CONTENT TO
FOCUS WIDESPREAD SCATTERED SHOWERS/STORMS WITH SOME ORGANIZATION.
WPC HAS AN ELONGATED SLIGHT RISK FOR EXCESSIVE RAINFALL ACROSS
THIS REGION THAT INCLUDES AREAS PARTICUALRLY HIT HARD BY HEAVY
RAINS FROM CINDY OVER THE PAST FEW DAYS...SO WITH LIGHT STEERING
FLOW FLOODING CONCERNS PERSIST FOR SRN PARTS OF AL/MS/LA AND THE
WRN FL PANHANDLE. POTENTIAL EXISTS FOR SOME 1-3 INCH AMOUNTS WITH
LOCALLY HIGHER VALUES FROM ERN NC/PARTS OF SC INTO SRN AL/MS AND
ACROSS TX INTO THE SRN HIGH PLAINS/ROCKIES AS AIDED THERE BY
UPSLOPE FETCH UNDERNEATH SEWD DIGGING IMPULSES AND FAVORABLE UPPER
DIFFLUENCE. SRN/SERN TX ACTIVTY FOCUS TODAY WILL BE DRIVEN
PRIMARILY FROM MESO-BOUNDARIES SET DOWN BY CURRENT CONVECTION AND
HAVE INCREASED UNCERTAINTY AND POTENTIAL. HAVE SHIFTED THE EARLIER
ISSUED AREA SOUTHWARD AS PER LATEST CONVECTIVE TRENDS AND THIS
REMAINING AREA OFFERS SIGNIFICANT SHORT TERM LOCAL POTENTIAL AS
CELL MERGERS AND OUTFLOW INTERSECTIONS ARE CURRENTLY PRODUCING
SOME HEAVY LOCAL AMOUNTS.

...MEANWHILE HAVE DISCONTINUED EARLIER ISSUED MARGINAL THREAT
AREAS FOR NEW ENGLAND AND CENTRAL FL WHERE THE THREAT IS
REDUCED...
