NWS Houston/Galveston, TX wrote its last area forecast discussion before the first event at Aug 22, 12:30 PM CST, 2 hours earlier.
SOUTHEAST TEXAS FORECAST DISCUSSION NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX 130 PM CDT THU AUG 22 2002 CONVECTION NOT AS WIDESPREAD AS EXPECTED...MAYBE DUE TO SOME WEAK SUBSIDENCE ON THE WESTERN EDGE OF POORLY DEFINED 50H CIRCULATION. THIS FEATURE WILL WEAKEN AND SHIFT WEST WITH TIME. MOISTURE ON THE EASTERN FRINGE OF THIS SYSTEM SHOULD REMAIN OVER THE AREA ON FRI-SAT SO IT SEEMS REASONABLE THAT SCATTERED TSRA WILL PERSIST INTO THE FIRST HALF OF THE WEEKEND. HAVE LEANED TOWARD THE ETA MODEL AS IT KEEPS DEEPER MOISTURE OVER SE TX THROUGH SATURDAY. AVN IS MUCH DRIER AND FEEL DRYING TREND IS A BIT OVERDONE. STORM MOTION ON FRI WILL AGAIN BE SLOW AND LOCALLY HEAVY RAIN STILL A POSSIBILITY. BOTH THE AVN/ETA HINT AT 85H CONVERGENCE AT 18Z FRI...SO EXPECT COVERAGE TO BE WIDESPREAD BY AFTERNOON. IN THE LONG TERM...50H RIDGE OVER THE WESTERN U.S. WILL EXPAND AMPLIFY WHILE A 50H TROF OVER THE MISSISSIPPI VALLEY DIGS SOUTH. THE UPPER FLOW IS NORTHERLY AND ANY CONVECTIVE COMPLEX THAT DEVELOPS NORTH OF THE REGION WILL SINK SOUTH. A WEAK FRONT IS ALSO FCST TO PUSH INTO EXTREME NE TX. MSTR WILL FOCUS ON THIS BNDRY SUN-TUE. CANADIAN AND ECMWF BRING THE 50H TROF MUCH FURTHER SOUTH THAN THE OTHER SOLUTIONS. 50H ARE ACTUALLY LOWER MON-TUE THAN THEY ARE TODAY SO THINK RAIN CHANCES WILL BE HIGHER THAN EXTENDED MODELS CURRENTLY INDICATE. 43/47 .HGX...NONE. PRELIMS... CLL BB 075/095 075/096 075 332 IAH EB 076/094 076/095 075 343 GLS TB 081/090 081/090 082 252
