Area forecast discussion, Sep 14, 3:00 PM CDT, 3 hours 33 minutes before
SOUTHEAST TEXAS FORECAST DISCUSSION NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX 300 PM CDT THU SEP 14 2000 SURPRISING AMOUNT OF TSTM COVERAGE THIS AFTN INDICATES MODELS WERE OFF ON RATE OF DRYING ADVERTISED IN THE 00Z RUN. UPDATED ZONES AROUND 1 PM TO UP POPS THESE REGIONS. WITH NO CAP AND HIGH CAPE TSTMS HAVE TRIGGERED BEHIND SEVERAL OUTFLOWS FROM LAST NIGHT'S STORMS A AND FEW OF THESE HAVE HAD VERY HIGH VIL DENSITY AND DUMPED A COUPLE OF INCHES OF RAIN IN A FEW LOCATIONS. CURRENT ACTIVITY NOT APT TO DIE DOWN UNTIL A COUPLE OF HOURS AFTER SUNSET, SO WILL KEEP SLIGHT CHANCE OF EVENING POPS ALL ZONES IN FIRST PERIOD. THE NEXT THING TO CONSIDER IS HOW DEEP MOISTURE WILL BE WHEN FRONT ARRIVES TOMORROW. ALTHOUGH FLOW WILL SHIFT NORTHEAST-NORTH BEFORE THE FRONT ARRIVES... STILL BELIEVE THE THERMAL BOUNDARY MAY BE SUFFICIENT TO KICK OFF SHOWERS AND THUNDERSTORMS ALONG THE FRONT... ESPECIALLY CLOSER TO THE COAST. WILL HENCE RETAIN 30 PCT CHANCE FOR TIER OF INLAND COUNTIES AND ALONG THE COASTAL TIER FOR FRIDAY. AFTER THAT... CLEARING & COOLING TREND SHOULD SET UP A NICE WEEKEND. TRACK OF T.D.11 IN MODELS IS VASTLY DIFFERENT NOT ONLY IN DIFFERENT MODELS BUT EVEN FROM RUN TO RUN (I.E. 84 HR POSITION OF 00Z MRF COMPARED TO 72 HR AVN.) EARLIER MRF PREFERRED TO BRING PULL STORM NORTHWARD INTO LONGWAVE TROUGH OVER NE U.S. WHILE CURRENT RUN OF AVN PREFERS MORE NORTHWESTERLY TRACK... AS DID NHC FOLKS AT TIME OF 11 AM DISCUSSION. BEYOND SUNDAY... THE CURRENT THINKING IS THAT THIS STORM WILL TAKE WEST-NORTHWEST TRACK AND THEN HEAD WESTWARD... WITH TRACK DRIVEN BY UPPER LEVEL EASTERLIES SOUTH OF THE SUBTROPICAL RIDGE AXIS... BUT THIS IS YET TO BE SEEN. HOPEFULLY STORM WILL TAKE ONE OF THESE TWO TRACKS SO THAT IN EXTENDED FORECAST WILL BE CAN ANTICIPATE A CONTINUANCE OF DRY LATE SUMMER WEATHER... THOUGH THE LATTER TRACK FOR T.D. MAY BRING LONG FETCH TO EAST/NORTHEAST FLOW OVER NRN GULF... POSSIBLY BRINGING TIDES UP ABOVE NORMAL LEVELS. 38/46 PRELIMS...
