Area forecast discussion, Nov 12, 2:25 PM CST, 5 hours 18 minutes before
SOUTHEAST TEXAS FORECAST DISCUSSION NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX 225 PM CST SUN NOV 12 2000 MINI-SUPERCELL THUNDERSTORMS HAVE DEVELOPED ALONG THE WRN CWA AT EARLY AFTERNOON...ONE OF WHICH PRODUCED AN APPARENT TORNADO AND DAMAGE IN COLORADO COUNTY EARLIER. SO THE SEVERE THREAT IS THE PRIMARY SHORT TERM FORECAST ISSUE. OTHERWISE THE MAIN FORECAST ISSUES ARE POPS TONIGHT/MON... TEMPS TUE/WED...POPS THU...AND TEMPS FRI-SUN. THE 12Z NCEP MODELS ARE IN FAIR TO GOOD AGREEMENT. THE MAIN DIFFERENCE IS THE AVN BLASTING THE FRONT OFF THE COAST QUICKLY... WITH THE ETA/NGM SOLUTION A MORE SEDATE PUSH. PREFER THE ETA/NGM SOLUTION BASED ON THE FRONT'S SLOW PROGRESS...LACK OF STRONG PRESSURE RISES BEHIND IT...AND ALREADY E-W ORIENTATION OF THE FRONT WEST OF SJT...INDICATING IT'S NEARING THE END OF SWD PROGRESS. ONCE THE SHORT WAVE TROUGH AND JET STREAK MOVE EWRD THE FRONT SHOULD ACCELERATE...BUT NOT AS MUCH AS THE AVN. EXPECT SEVERE WEATHER TO CONTINUE INTO THE EVENING. CONFIDENCE IS HIGH FOR CATEGORICAL POPS OVERNIGHT...SO WILL RETAIN MOST OF CURRENT FORECAST IN THIS REGARD. THE LATEST ETA/NGM INDICATE ENHANCED ISENTROPIC LIFT OVER SERN TX AS THE FRONT PUSHES OFF THE COAST...SO WILL EXTEND SHOWERS/LIGHT RAIN POPS THROUGH THE DAY TOMORROW...WITH SLOWER CLEARING FROM NW TO SE. SIMILARLY...MON NIGHT TEMPS WILL PROBABLY NOT DROP AS FAR AS IN THE CURRENT FORECAST...SO WILL BOOST SOME. HOWEVER...WILL STICK WITH CLOSE TO PAST PATH OF SHADING AWAY FROM THE TOO WARM FWC AFTER FROPA...THEN AVOIDING THE TOO COLD FAN ON RETURN FLOW WARMUP. NO CHANGES TO THE EXTENDED...THU STILL LOOKS FAVORABLE FOR THE NEXT FRONT/POPS....THEN SEASONALLY COOL WITH A SLIGHT CHANCE OF RAIN OVER THE WEEKEND. .KHGX...SCA IN EFFECT FOR ALL BAYS AND GULF WATERS. 31/47/48 PRELIMS...
