VALID 151300Z - 161200Z.

...NO TSTM AREAS FORECAST...

...SYNOPSIS/FORECAST...
PROGRESSIVE FAIRLY HIGH AMPLITUDE PATTERN WILL CONTINUE...WITH RIDGE
ALONG THE W CST AND MEAN TROUGH OVER THE EAST. SFC HIGH NOW OVER
THE LWR MS VLY WILL BEGIN TO WEAKEN AND MOVE EWD TODAY AS LEAD
IMPULSE OF DOUBLE-STRUCTURED DISTURBANCE OVER THE NRN/CNTRL RCKYS
CONTINUES ESEWD.  WITH TIME...EXPECT WEAK SURFACE TROUGH TO DEVELOP
OVER THE COASTAL WATERS OF THE NWRN GULF.  THIS WILL ALLOW LOW-LEVEL
MOISTURE TO EDGE NWWD AND POSSIBLY REACH THE CNTRL/SRN TX GULF
COASTAL AREAS LATE IN THE PERIOD.  INCREASING MOISTURE INFLOW AND
CONVERGENCE OVER THE NW GULF OF MEXICO MAY RESULT IN ISOLATED
THUNDERSTORMS IN THAT AREA EARLY THURSDAY.  HOWEVER...GIVEN LOW
AMPLITUDE AND NRN TRACK OF UPPER DISTURBANCE...EXPECT THAT ACTIVITY
SHOULD REMAIN OFFSHORE THROUGH 12Z.

ELSEWHERE...COOL MID LEVEL TEMPERATURES ACCOMPANYING UPPER-LEVEL
TROUGH MAY RESULT IN AN ISOLATED LIGHTNING STRIKE OR TWO OVER THE
INTERMOUNTAIN WEST TODAY.  AND IN THE EAST...SCATTERED LOW-TOPPED
STORMS EXPECTED TO PERSIST FOR ANOTHER 12 HRS OR SO BENEATH SHARP
UPPER TROUGH OFF THE NC CST.
