SOUTHEAST TEXAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
1001 PM CDT SAT JUL 13 2002

MULTICELLUAR ACTIVITY LOOKS TO BE EVOLVING INTO AN MCS WITH THE BULK
OF THE HEAVY RAINFALL BETWEEN WHARTON AND COLORADO TO LIBERTY
COUNTIES.  RADAR AND SATELLITE SHOWED ACTIVITY DEVELOPING TO THE
SOUTHWEST OF THE MCS ALONG THE SEABREEZE.  00Z UPPER AIR ANALYSIS
SHOWS SE TX IN THE ENTRANCE REGION OF THE JET WITH THE 300 AND 200 MB
TROUGH IN THE PANHANDLE AND A LOW OFF THE COAST.  THIS HAS PUT SE TX
IN AN UPPER DIFFLUENT PATTERN THIS EVENING.  VERY MOIST AIR WAS IN
PLACE IN THE LOWER AND MID LEVELS AS WELL...WITH PW/S NEAR 2 INCHES.

FORECAST ITEMS TO CONSIDER...RAINFALL TRENDS AND TEMPERATURES.  FOR
THE OVERNIGHT LOWS WILL NEED TO LOWER A CATEGORY GIVEN CURRENT
READINGS.  FOR THE RAINFALL...GIVEN THE 00Z ETA AND CURRENT TRENDS
FEEL THAT THE POPS CAN BE LOWERED OVER THE FAR NORTHWESTERN COUNTIES
HAS ENDED.  WILL NEED TO UP THE POPS ELSEWHERE...ESPECIALLY IN THE
SOUTHWEST.  QUITE A BIT OF RAINFALL HAS FALLEN OVER LOCATIONS BETWEEN
METRO HOUSTON AND WHARTON COUNTY.  THE LATEST RUC IS INDICATING
SURFACE MOISTURE CONVERGENCE THROUGH MUCH OF THE NIGHT...WHILE UPPER
DIFFLUENCE IS FORECAST BY THE AVN AND ETA TONIGHT.  HOWEVER...BOTH
MODELS DID NOT INITIALIZE THE 300 MB LOW OFF THE COAST VERY WELL
THOUGH THE AVN LOOKS TO BE THE BEST.  OUR FEELING IS THAT GIVEN THE
CURRENT TRENDS AND EXPECTED FORECAST FOR TOMORROW...WILL ISSUE A FLASH
FLOOD WATCH FOR THE CENTRAL COUNTIES...SOUTH OF A LINE FROM
SOMERVILLE TO NEAR LOVELADY TO SHEPHERD AND NORTH OF A LINE FROM EL
CAMPO TO PASADENA TO LIBERTY.
