NATIONAL WEATHER SERVICE BROWNSVILLE TX
612 PM CDT THU APR 23 2009

...THREAT OF ERRATIC WILDFIRE BEHAVIOR FRIDAY...

.CRITICAL FIRE WEATHER CONDITIONS WILL DEVELOP FRIDAY FOR PORTIONS
OF DEEP SOUTH TEXAS. LOW PRESSURE OVER NORTH TEXAS AND EVEN NORTH
MEXICO WILL INTERACT WITH RETREATING HIGH PRESSURE OVER THE GULF
OF MEXICO. THIS WILL RESULT IN WINDY CONDITIONS NEAR THE COAST AND

LACK OF RAINFALL OVER THE PAST SIX MONTHS WILL CONTRIBUTE TO THE
WILDFIRE POTENTIAL. HIGHER RELATIVE HUMIDITY VALUES NEAR THE COAST
WILL CONFINE THE AREA OF THE WORST THREAT TO THE WESTERN PORTIONS
OF DEEP SOUTH TEXAS.
