SOUTHEAST TEXAS FORECAST DISCUSSION NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX 215 PM CDT MON AUG 6 2001 SHRA/TSRA FINALLY DEVELOPING AS CONVECTIVE TEMPERATURE IS REACHED. EXPECT DECENT COVERAGE THIS EVENING AND ISOLATED CONVECTION WILL PERSIST OVER THE EASTERN 2/3RDS OF THE REGION OVERNIGHT. THINK TUESDAY WILL BE SIMILAR TO TODAY AS HIGH PW AIR REMAINS RESIDENT OVER THE REGION AND 50H SHEAR ZONE IS JUST TO THE WEST OF SE TX. LACK OF A LOW LEVEL TRIGGER AND MODEST UPPER LEVEL DIVERGENCE IS A BIT UNSETTLING. STILL OF THE OPINION THAT DAYTIME HEATING WILL BE SUFFICIENT TO SPAWN MANILY AFTERNOON CONVECTION WEDNESDAY. A BIT OF A BREAK THURSDAY/FRIDAY AS UPPER LEVEL HIGH BUILDS ACROSS SE TX... PWS DROP AND GRADIENT TIGHTENS REDUCING POSSIBLE SEA BREEZE ACTIVITY. HEIGHTS FALL AGAIN SATURDAY/SUNDAY AND MSTR LEVELS RETURN TO AROUND 1.9 INCHES SO WILL BRING A CHANCE OF TSRA BACK INTO THE FORECAST. MARINE: WEAK GRADIENT EQUALS LIGHT WINDS TONIGHT INTO WEDNESDAY.
