SOUTHEAST TEXAS FORECAST DISCUSSION NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX 210 PM CDT WED MAY 3 2000 PARTLY CLOUDY OVER SERN TX EARLY THIS AFTERNOON. THE SEABREEZE IS TYPICAL GIVEN THE WEAK SYNOPTIC FLOW AND INLAND HEATING. A FEW SHOWERS MAY IGNITE ALONG THE SEABREEZE THIS AFTERNOON...BUT CHANCES ARE LOW ENOUGH TO HANDLE WITH NOWCASTS. THE MAIN FORECAST ISSUE IS THE TIMING...INTENSITY...AND DURATION OF CONVECTION. THE 12Z MODELS ARE IN FAIR AGREEMENT WITH THE SYNOPTIC SCALE FEATURES. HOWEVER...THESE FEATURES ARE SLOW MOVING AND WEAKENING...INDICATING MESOSCALE FORCING COULD HAVE A LARGE ROLE IN THE SENSIBLE WEATHER. OVERALL...PREFER SOMETHING CLOSE TO THE ETA...WITH A LINEAR MCS DEVELOPING ALONG THE WEAK ENE/WSW BOUNDARY ACROSS ECNTRL TX BY 06Z...THEN PROPAGATING SSEWRD TO NEAR I-10 BY 12Z...THEN TO THE SWRN ZONES BY 16Z. THE AVN LOOKS A BIT STRONG WITH FORCING FOR FRI...BUT WILL RETAIN SMALLISH CHANCE POPS THE NERN 2/3 OF THE CWA...WITH 20 POPS IN THE FAR SW. WILL DRY OUT THE EXTENDED WITH SLIGHT CHANCE POPS SAT AND NONE SUN/MON. SPECIFICALLY ON CONVECTION...WILL RE-ISSUE AN SPS WITH FOCUSED TIMING OF 09-15Z FOR THE PEAK IN MOST AREAS (SORRY...ANOTHER SOGGY RUSH HOUR)...WITH RAINFALL AMOUNTS GENERALLY 1-3 INCHES...AND SEVERE THREATS OF DAMAGING WIND/LARGE HAIL. WILL HOLD OFF ON A FLASH FLOOD WATCH SINCE 1) THREAT IS TOWARD THE END OF THE FIRST PERIOD...2) NOT EXPECTING MASSIVE RAIN...BUT POTENTIALLY ENOUGH FOR PROBLEMS.
