AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIDLAND TX 240 PM CDT SAT JUL 31 1999 WOULD APPEAR TO BE GOOD DAY FOR STORMS AS LITTLE CAP... PLENTY OF MOISTURE... AFTERNOON HEATING... COOLING ALOFT... A COLD FRONT SAGGING SOUTH... AND A TUTT LOW WORKING ITS WAY UP THE RIO GRANDE. QUITE A BIT OF ACCAS AROUND THROUGH THE MORNING... BUT STORMS GOT A LATE START TODAY. STORMS GOING UP NEAR KINK AND OVER THE DAVIS MOUNTAINS... WITH MOST POTENT STORMS DEVELOPING SOUTH OF THE BORDER NEAR RIO GRANDE VILLAGE. 19Z SURFACE ANALYSIS HAS FRONT NEAR A KCDS... KLBB... TO KHOB LINE. THIS FRONT SHOULD PROVIDE NORTHERN PART OF AREA BETTER CHANCE STORMS WITH SLIGHTLY COOLER TEMPS. STORMS THAT MAY DEVELOP ALONG THE FRONT WOULD TEND TO PUSH IT FARTHER SOUTH INTO THE AREA THAN MODELS INDICATE. CONVECTION LAST FEW DAYS HAS NOT STOPPED AT SUNSET... BUT LINGERED INTO THE LATE NIGHT/EARLY MORNING HOURS. EXPECT STORMS TO DO SAME TONIGHT. IN THE LONG RUN... NOT EXPECTING MUCH IN THE WAY OF CHANGES AS UPPER RIDGE STAYS OVER AREA WITH TEMPS WARM. HISTORICALLY LAST WEEK JULY AND FIRST WEEK AUGUST IS WARMEST TIME OF YEAR FOR AREA. INITIAL NUMBER FOLLOW.
