.PREV DISCUSSION... (ISSUED 526 AM CDT THU JUL 27 2006)

DISCUSSION...
EARLY THIS MORNING UPPER LOW SPINNING OVER EAST TX AND ALONG WITH
SURFACE HIGH PRESSURE IN THE GULF IS PROVIDING DEEP AND TROPICAL
MOISTURE AND SHOWERS AND ISOLATED THUNDERSTORMS TO THE FOUR STATE
REGION. THIS LOW WAS BETWEEN HIGH PRESSURE RIDGE OVER THE WEST AND
AND ANOTHER OVER THE EASTERN GULF AND SOUTHEAST STATES. THE LOW
WILL CONTINUE TO PROVIDE SHOWERS AND THUNDERSTORMS ACROSS THE
FORECAST AREA TODAY AND TONIGHT...THEN ACROSS THE NORTHERN
SECTIONS ON FRIDAY AS IT PHASES WITH BROAD TROUGH OVER THE CENTRAL
AND NE STATES. THE UPPER RIDGE IN THE GULF BUILDS WEST AND THE TWO
HIGH PRESSURE SYSTEMS REFORM INTO A LARGE SYSTEM THAT WILL COVER
MUCH OF THE CENTRAL AND SOUTHERN SECTIONS OF THE COUNTRY. HOWEVER
WEAK DISTURBANCES WILL ROTATE AROUND THE NORTHERN AND NORTHEAST
PERIPHERY OF THE BUILDING HIGH AND PROVIDE THE NORTHEAST ZONES
WITH THE BETTER CHANCES OF RAIN THROUGH SATURDAY. INTO EARLY WEEK
AROUND THE EASTERN EDGE OF THE UPPER RIDGE...DISTURBANCES WILL
PROVIDE A CHANCE OF SHOWERS AND THUNDERSTORMS. BY WEDNESDAY OF
NEXT WEEK THE UPPER RIDGE STARTS TO BREAK DOWN WITH THE FOUR STATE
REGION IN A WEAKNESS WITH A DEEPENING TROUGH DROPPING SOUTH INTO
THE CENTRAL SECTIONS OF THE COUNTRY SENDING ANOTHER SIGNIFICANT
CHANCE FOR SHOWERS AND THUNDERSTORMS TO THE AREA. HEAVY RAINFALL
WILL BE LIKELY FOR THE EAST TEXAS AND NORTH WEST...AND SOUTHWEST
ARKANSAS ZONES TODAY AND INTO SOUTHWEST ARKANSAS TONIGHT. WITH
RAINFALL RATES APPROACHING ONE TO NEAR TWO INCHES PER HOUR IN SOME
LOCATIONS...PONDING OF WATER IN STREETS...LOW LYING...AND POOR
DRAINAGE AREAS WILL BE POSSIBLE TODAY AND INTO TONIGHT. SOME LOCATIONS
MAY SEE ONE TO THREE INCHES OF RAIN...WITH ISOLATED HIGHER AMOUNTS
TO FOUR INCHES. EARLY MORNING TRAVELERS SHOULD REMAIN ALERT TO
HEAVY RAINFALL AND AVOID ANY AREAS OF HIGH WATER THAT DEVELOPS.
