SOUTHEAST TEXAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
300 AM CST WED MAR 28 2001
NORTHWEST FLOW PATTERN CONTINUES OVER SE TX THIS FORECAST PERIOD.
FORECAST PROBLEM IN THE FIRST TWO PERIODS CONCERNS THE IMPACT OF THE
CURRENT MCS...THEN THE SHORTWAVE TROUGHS MOVING OVER THE AREA LATER
TODAY. THE AVN AND RUC DID A BETTER JOB WITH PLACING THE SURFACE
FEATURES AT 06Z...THOUGH THE ETA WAS CLOSE BEING JUST A TAD OFFSHORE.
THE CURRENT SITUATION AND THE MODELS ALL POINT TO KEEPING THE FLASH
FLOOD WATCH UP FOR TODAY...AND WILL UPDATE AND EXTEND IT THROUGH THE
AFTERNOON. THE NEXT SHORTWAVE CURRENTLY OVER THE PANHANDLE LOOKS
TO MOVE INTO SE TX THIS AFTERNOON. GIVEN THE VICINITY OF THE WARM
FRONT...WHICH MAY MOVE ONSHORE...AND PW/S STAYING FAIRLY CONSTANT
AROUND 1.4 INCHES...THIS SEEMS TO BE THE BEST ROUTE TO GO. CONDITIONS
ARE ALSO FAVORABLE FOR SMALL HAIL AND WILL MENTION THIS POSSIBILITY
CLOSER TO THE COAST. THE LOCATION OF THE WARM FRONT WILL ALSO BE A
MAJOR FACTOR IN THE TEMPERATURES FOR TODAY. THE FWC AND MAV LOOK TO
BE MUCH TOO WARM OVER THE INLAND COUNTIES TODAY AND WILL GO CLOSER
TO YESTERDAY/S HIGHS THAN THE MOS.
AS FAR AS FOR THE LATER PERIODS...WILL NOT CHANGE THE CURRENT FORECAST
TOO MUCH. SHORTWAVE TROUGHS MOVING ALONG THE NORTHWEST FLOW WILL
CONTINUE TO AFFECT SE TX DURING THIS PERIOD.
EAST WINDS PILING UP THE TIDES A BIT AND LEVELS WERE ONE TO TWO FEET
ABOVE NORMAL. EXPECT THE TIDES TO RELAX LATER TODAY AS THE WINDS
BECOME MORE SOUTHERLY AND DIMINISH.
