NWS Houston/Galveston, TX wrote its last area forecast discussion before the first event at Jun 24, 2:51 PM CST, 14 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX 351 PM CDT WED JUN 24 2009 ...UPDATE TO INCLUDE HEAT ADVISORY... WITH RECORD TEMPS BEING REACHED TODAY AND MORE HEAT TOMORROW...WILL ISSUE A HEAT ADVISORY. LOCAL CRITERIA CALL FOR HEAT INDEX OF 108F OR MORE FOR TWO STRAIGHT DAYS. SURROUNDING AREAS IN THE HOUSTON AREA AS WELL AS MUCH OF SE TX HAVE REACHED 108F TODAY AND WITH LITTLE CHANGE IN CONDITIONS TOMORROW...SOME AREAS COULD REACH A HEAT INDEX OF 108 TOMORROW. OH YA...KIAH REACHED 104F IN BETWEEN HOURLY OBS TO BREAK ALL TIME RECORD HIGH FOR JUNE. 39 && .PREV DISCUSSION... /ISSUED 226 PM CDT WED JUN 24 2009/ ..RECORD HIGH TEMPERATURES POSSIBLE AGAIN TOMORROW... DISCUSSION... AT THE TIME OF THIS WRITING KIAH HAS BROKEN THE RECORD HIGH TEMPERATURE FOR TODAY WITH 100F SO FAR AND THE OLD RECORD BEING 99F. KCLL IS ONE DEGREE SHY OF TYING THE RECORD HIGH TEMPERATURE FOR TODAY AT 102F. CHANCES ARE THAT THE RECORD HIGH AT KCLL WILL ALSO GO DOWN WITH 2-3 HRS OF GOOD HEATING LEFT TODAY. ALL TIME RECORD HIGH FOR JUNE AT KIAH IS 103F AND 107F AT KCLL. SAFE TO SAY THAT THE JUNE ALL TIME HIGH AT KCLL IS SAFE BUT COULD BE BROKEN AT KIAH EITHER LATER TODAY OR TOMORROW. BOTH NAM/GFS GUIDANCE SUGGEST 104F FOR KCLL AND 100/101F FOR KIAH. RECORD HIGH TEMPS FOR BOTH LOCATIONS IS 100F. I AM GOING OUT ON A LIMB AND SAYING THAT THOSE RECORDS WILL GO DOWN TOMORROW AS WELL. FOR FRIDAY THE RECORD HIGH AT BOTH KCLL AND KIAH IS 102F WHICH MAY BE A LITTLE HARDER TO REACH BUT COULD BE CLOSE. MODEL GUIDANCE SUGGEST MAX TEMPS OF 97F FOR BOTH AREAS BUT THINK TEMPS WILL AGAIN BE CLOSER TO 100F FOR MAX TEMP. THE MODELS DO SHOW A WEAK BACK DOOR FRONT THAT COULD WORK INTO E TX LATE TONIGHT INTO TOMORROW. THIS BOUNDARY IS CURRENTLY LOCATED BACK THROUGH ARK/MS. THE NAM IS MORE AGGRESSIVE WITH THIS BOUNDARY AND ACTUALLY HAS DEWPOINT TEMPS IN THE 50S BEHIND IT WHICH MAKES IT INTO THE NORTHERN HALF OF THE CWA. WITH THE POSSIBILITY OF RECORD HIGH TEMPS...I HATE TO KEEP THE 10-20 POPS FOR ISOLATED THUNDER IN THE FORECAST BUT THE FACT IS THAT THIS COULD HAPPEN TOMORROW. SHOULD SUCH A BOUNDARY SET UP WHICH IS POSSIBLE AND TEMPS DO REACH THE LOW 100S...ISOLATED CONVECTION WILL BE POSSIBLE GIVEN LIFT ALONG THE BOUNDARY AND MOISTURE POOLING ALONG IT. SO SLIGHT TSRA CHANCES WILL REMAIN FOR TOMORROW AS WELL. BEYOND TOMORROW THE PROSPECTS OF ANY RAINFALL STILL LOOK SLIM TO NONE. THE GFS TRIES TO GIVE SOME HOPE WITH ANOTHER FRONTAL BOUNDARY WORKING INTO SE TX MON/TUE. THE GFS STILL WANTS TO RETROGRADE THE RIDGE BACK OVER THE SOUTHERN ROCKIES WHICH HAS YET TO PAN OUT. NEEDLESS TO SAY...CONFIDENCE IN THE FORECAST MODELS WITH THIS SCENARIO IS LOW AT BEST. I WOULD NOT BE SURPRISED IF THE RIDGE REMAINS LOCKED OVER THE SOUTHERN PLAINS. STILL SHOULD THE RIDGE SHIFT A LITTLE THAT MIGHT TAKE THE EDGE OFF MAX TEMPS BY A COUPLE OF DEGREES. THE FORECAST WILL STILL KEEP TEMPS ABOVE 95F IN THE EXTENDED RANGE EVEN THOUGH THE GFS SUGGESTS 93-95F FOR SOME AREAS EARLY NEXT WEEK. ALSO IF THE RIDGE DOES BREAK DOWN SOME AFTERNOON CONVECTION LOOKS A LITTLE MORE PROMISING BUT TOO FAR OUT IN THE EXTENDED RANGE OF THE FORECAST TO DEPEND ON THOSE DETAILS. PERSISTENCE SEEMS LIKE A VERY GOOD FORECAST GIVEN THE LATEST WEATHER TRENDS. 39 AVIATION... 18Z TAF DISCUSSION...HIGH LEVEL CU FIELD HAS BEGUN TO DEVELOP ACROSS ROUGHLY THE NORTHERN HALF OF SOUTHEAST TEXAS AS OF LATE THIS MORNING AND EARLY THIS AFTERNOON. 18Z TAFS WILL CARRY SCT050 TO SCT060 FOR THIS AFTERNOON. CANNOT COMPLETELY RULE OUT ISOLATED LATE AFTERNOON AND EARLY EVENING CB DEVELOPMENT...SO WILL CARRY THIS IN THE NORTHERN TAF SITES. SKC TONIGHT WITH SOME IFR/LIFR FOG AND CEILINGS POSSIBLE AGAIN AT LBX. WINDS WILL GENERALLY BE LIGHT AND FROM THE NORTH TO NORTHWEST DURING THE NIGHT AND EARLY MORNING HOURS AND SOUTH TO SOUTHEAST AT AROUND 10 KNOTS DURING THE MID AFTERNOON TO EARLY EVENING HOURS. 42 MARINE... WEAK SURFACE HIGH PRESSURE WILL PERSIST OVER THE NORTHWEST GULF. WINDS WILL GENERALLY BE VARIABLE AT 10 KNOTS OR LESS. AN ONSHORE FLOW WILL BECOME BETTER ESTABLISHED AT THE END OF THE WEEK AND ON INTO THE WEEKEND. WAVE HEIGHTS WILL BE MAINLY 3 FEET OR LESS. 42 && .PRELIMINARY POINT TEMPS/POPS...
