.PREV DISCUSSION... /ISSUED 1109 AM CDT TUE MAY 26 2015/

DRIER AIRMASS MOVED INTO N HALF OF SE TX IN THE WAKE OF LAST
NIGHTS STORMS. PW`S NORTH OF I-10 GENERALLY ~1.3". HOWEVER THEY
TREND HIGHER AS YOU GET TO THE COAST WHERE 1.9" PW`S ARE POOLING
ALONG A REMNANT BOUNDARY ALONG W/ ISO SHRA. EXPECT THIS BOUNDARY
TO WASH OUT AND MOISTURE TO BE TRANSPORTED BACK INLAND LATER
TODAY.

SCATTERED SHOWERS AND THUNDERSTORMS MAY DEVELOP THIS AFTERNOON AS
THE ATMOSPHERE HEATS UP. GFS/ECMWF & SOME HIRES MODELS POINT THAT
DIRECTION. NO SIGNIFICANT DISTURBANCES ARE NOTED ON SATELLITE
THAT POINT TOWARD ANY SORT OF REPEAT OF WHAT OCCURRED LAST NIGHT.
WE WOULD EXPECT MAINLY SCATTERED POPCORN TYPE ACTIVITY THE AREA
TYPICALLY SEES IN THE SUMMER MONTHS. HOWEVER...PORTIONS OF HARRIS
& FORT BEND COUNTIES THAT RECEIVED TORRENTIAL RAINFALL AMOUNTS
OVERNIGHT CANNOT HANDLE EVEN A VERY LOCALIZED HEAVY DOWNPOUR
WITHOUT THE RISK OF ADDITIONAL FLOODING. WENT AHEAD AND EXTENDED
THE FF WATCH FOR THOSE 2 COUNTIES UNTIL 6PM. SCATTERED PRECIPITATION
SHOULD TAPER OFF BY EARLY EVENING WITH THE LOSS OF HEATING.

JUST MINOR TWEAKS TO THE POPS FOR THE UPDATE. BUMPED UP HIGHS A
TOUCH INLAND BASED ON CURRENT SUNNY SKIES AND WARM CONDITIONS. 47
