NWS Houston/Galveston, TX wrote its last area forecast discussion before the first event at May 27, 1:51 PM CST, 1 hour 26 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX 251 PM CDT TUE MAY 27 2008 .DISCUSSION... CONVECTION ASSOCIATED WITH LAST NIGHT MCS STILL GOING STRONG AS IT CONTINUES TO MOVE SSE INTO OUR CWFA. THIS PROMPTED THE SEVERE TSRA WATCH ISSUED EARLY THIS AFTN. AND GIVEN THE CURRENT TRENDS WE WILL KNOW SHORTLY HOW STRONG THE CAP REALLY IS. AND ALSO BECAUSE OF THE CURRENT TRENDS...THE WETTER/MORE ACTIVE 12Z NAM IS THE FAVORITE IN THE SHORT TERM. AS SUCH HAVE UPPED POPS FOR TONIGHT/TOMORROW AS WE ANTICIPATE ADDITIONAL CHANCES OF RAIN. THE REMNANTS OF THE ONGOING BATCH TO ACCOUNT FOR TONIGHT AS THIS ACTIVITY IS FCST TO COME TO A STOP OVER THE CENTRAL PORTIONS OF THE CWA. FOR TOMORROW MODELS ARE BRINGING ANOTHER DISTURBANCE IN (THIS ONE FROM THE EAST) RIGHT AOA PEAK HEATING. STRONG TSRA ONCE AGAIN A POSSIBILITY. THE END OF THE WEEK SHOULD SEE AN END TO ALL THE PCPN AS THE UPPER RIDGE RETROGRADES BACK OVER THE REGION. WARM/HUMID AND VERY LOW/NO POPS THROUGH THE WEEKEND. 41 && .AVIATION... DISTINCT COLD POOL (TEMPS IN THE 60S) NOTED BEHIND THE INCOMING LINE OF SHRA/TSTMS. THIS SHOULD KEEP THE PRECIP HEADED SWD INTO THE LATE AFTN AND EARLY EVNG HOURS. ASSUMING THE CURRENT MVMT REMAINS ABOUT THE SAME THE PRECIP SHOULD BE IN THE UTS AREA AROUND 21Z...CLL-CXO-LIBERTY RIGHT AROUND 22Z...CALDWELL-IAH-WINNIE LINE AROUND 23Z. NOT EXPECTING WIDESPREAD SVR WX WITH THE LINE...MORE OF THE PULSE VARIETY. WINDS HOWEVER SHOULD SHIFT TO THE NNE AND BE QUITE GUSTY ALONG THE LEADING EDGE. QUESTION IS IF/WHERE THE BOUNDARY STALLS LATER THIS EVENING & OVERNIGHT. CURRENTLY NOT PLANNING ON MENTIONING ANY THUNDER SOUTH OF IAH BUT MAY NEED TO IN THE 00Z TAFS BASED ON LATER TRENDS. PRECIP SHOULD GRADUALLY COME TO AND END WITH THE LOSS OF HEATING AND EXPECT MOSTLY VFR OVERNIGHT. WINDS BECOME QUITE LIGHT AFTER MIDNIGHT SO MAY SEE SOME PATCHY FOG AND LOW END MVFR OR HIGH END IFR CIGS DEVELOP. THOUGH ITS BEYOND THE CURRENT 18Z TAFS...IT LOOKS LIKE TSTMS MAY AGAIN POP UP ACROSS SE TX LATE WED AFTN. APPEARS LEFT OVER BOUNDARY FROM CURRENT STORMS OR A WEAK FRONTAL BOUNDARY SAGGING INTO THE AREA COULD BE THE FOCUS. LATE AFTN FCST SOUNDINGS SHOW AN INVERTED-V... WHICH WOULD POINT TO THE POTENTIAL FOR SOME STRONG WINDS ASSOCIATED WITH THE STORMS. 47 && .MARINE... CONVECTIVE COMPLEX STILL MOVING SWD INTO SE TX. A BIT OF UNCERTAINTY AS TO IF IT WILL MAKE IT ALL THE WAY TO THE COAST ALONG/E OF GLS, OR IF THERE WILL BE A BRIEF WIND SHIFT TO THE N ASSOCIATED WITH ANY OUTFLOWS. IF IT DOES INDEED MAKE IT ALL THE WAY TO THE COAST IT SHOULDNT BE UNTIL AROUND 7 PM BASED ON CURRENT MVMT. CURRENTLY PLAN ON GOING WITH CONTINUED ONSHORE FLOW IN THE 430PM PACKAGE FOR TONIGHT AND LET THE SWING SHIFT AMEND IF NEEDED. OTHERWISE...WINDS SHOULD KICK UP AGAIN TONIGHT - BUT LESS THAN PREVIOUS NIGHTS SO WILL NOT HOIST THE CAUTION FLAGS. GRADIENT REALLY SLACKENS WED AS WEAK FRONTAL BOUNDARY GETS A BIT CLOSER. LIGHT ONSHORE FLOW AND LOW SEAS SHOULD PERSIST INTO THE WEEKEND. 47 && .PRELIMINARY POINT TEMPS/POPS...
