AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
1025 AM CDT WED AUG 29 2012

.DISCUSSION...
ISAAC WILL BE AN INFLUENCE ON WINDS AND TEMPERATURES ACROSS SE TX
TODAY. AT 15Z THE STORM WAS LOCATED JUST INLAND ALONG THE SE LA
COAST. RAIN BANDS OVER THE WEST SIDE OF THE STORM WERE MOVING
ACROSS SW LA AND WERE NOT MOVING INTO SE TX OR THE UPPER TX
COASTAL WATERS AS YET. DO EXPECT ISOLATED BANDS TO POSSIBLY WORK
THEIR WAY INTO THE EASTERN COUNTIES LATER TODAY. THE MAIN IMPACTS
TO THE AREA WILL BE THE WINDS OVER THE FAR SOUTHEASTERN COUNTIES
DUE TO THE INCREASING PRESSURE GRADIENT...AND TEMPERATURES
REACHING INTO THE UPPER 90S DUE TO THE SUBSIDENT FLOW ALOFT OVER
THE WESTERN COUNTIES.

WINDS AT KGLS WERE ALREADY REACHING INTO ADVISORY CRITERIA.
EXPECT BOTH GALVESTON AND CHAMBERS COUNTIES TO HAVE WINDS 20 TO 30
MPH THROUGHOUT THE DAY AND ISSUED A WIND ADVISORY FOR THESE
COUNTIES. WILL KEEP AN EYE OUT FOR ANY INCREASING WINDS FURTHER
INLAND AND MAY UPDATE THE ADVISORY LATER TODAY.

TEMPERATURES AT KCLL REACHED TO 100 YESTERDAY. SINCE THE CLOUD
COVER MAY INCREASE A BIT...WILL GO WITH UPPER 90S OVER THE WESTERN
SET OF COUNTIES AND MID 90S IN THE CENTRAL AREAS. AN INCREASING
CLOUD COVER AND ISOLATED SHOWERS SHOULD KEEP TEMPERATURES EAST OF
THE INTERSTATE 45 CORRIDOR DOWN INTO THE LOWER 90S.
