Area forecast discussion, Aug 7, 2:00 AM CDT, 4 hours 48 minutes before
AREA FORECAST DISCUSSION...CORRECTED P07 POPS NATIONAL WEATHER SERVICE MIDLAND TX 155 AM CDT THU AUG 7 1997 06Z SURFACE ANALYSIS AND 88D SHOWS STRONG COLD FRONT... AT LEAST FOR THIS TIME OF YEAR... OVER NORTHERN BREWSTER... SOUTHERN PECOS AND NORTHERN TERRELL COUNTIES. GREATEST PRESSURE GRADIENT REMAINS OVER THE PANHANDLE AND SOUTH PLAINS ATTM. HEAVIEST RAINFALL OCCURRING NEAR FRONTAL BOUNDARY ATTM WITH WEAKER AREA OVER NORTHERN PERMIAN BASIN WEAKENING WITH TIME. WV IMAGERY SHOWING NICE TROPICAL CONNECTION OVER PORTIONS OF THE CWA. LOW CLOUDS HAVE MADE IT TO MIDLAND AS THEY CONTINUE SOUTHWARD. MODELS IN GOOD AGREEMENT WITH RAINY WEATHER PATTERN OVER THE FA NEXT 36 TO 48 HOURS AS S/W TROUGH HANGS OUT OVER THE TX PANHANDLE NEXT 24 HOURS BEFORE SLOWLY MOVING OVER N TX BY 48 HOURS. A SERIES OF WEAK DISTURBANCES WILL MOVE THROUGH THE AREA AS WELL. THIS COMBINED WITH THE RIGHT EXIT REGION OF THE H25 JET OVER OUR NORTHERN PORTIONS WILL PROVIDE ENOUGH UPWARD MOTION OVER THE FA TO KEEP A GOOD CHANCE OF PRECIPITATION OVER MUCH OF THE REGION. HOWEVER... WITH FRONT HAVING MOVED AS FAR SOUTH AS IT HAS EXPECT MAINLY STRATOFORM PRECIPITATION OVER THE NORTHERN PORTIONS. APPEARS THERE MAY BE ANOTHER MAXIMA TOMORROW AS AN AREA OF GOOD QVEC CONV CAN BE SEEN IN THE LAYER FROM H85 TO H3 ACCORDING TO ETA WITH NGM A LITTLE SLOWER AND FRONT BEGINS TO MOVE BACK NORTH. GIVEN EXPECTED SLOW MOVEMENT OF THUNDERSTORMS... ABUNDANT MOISTURE (PW GREATER THAN 1.25 INCH)... AND TROPICAL CONNECTION BELIEVE A FFA MAY NEED TO BE CONSIDERED LATER TODAY IN VICINITY OF AFOREMENTIONED FRONT... ESPECIALLY IF IT STALLS. TEMPERATURES REALLY GOING TO BE TOUGH THIS TIME AROUND AS CLOUD COVER... SHRA/TSRA... AND QUASI/STATIONARY FRONT WILL ALL PLAY A DIFFICULT ROLE. ATTM WILL LEANING ON THE COOL SIDE OF NGM FOR HIGHS AS AVN STILL APPEARS TO BE ON THE COOL SIDE... ESPECIALLY GIVEN ITS 14 DEGREE TEMPERATURE DEPARTURE YESTERDAY. AS FOR LODWS... WILL KEEP WITH PERSISTENCE WITH A TOUCH OF GUIDANCE AS CLOUD COVER SHOULD KEEP DIURNAL VARIATION WITHIN 10 TO 15 DEGREES. MAF 78/66 65 CNM 80/66 54 MRF 78/60 55 P07 86/72 75 EARLE
