SOUTH PLAINS AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LUBBOCK TX
229 AM CDT THU AUG 9 2001

PREVIOUS MODEL RUNS MOVED UPPER LOW FURTHER WEST THAN CURRENT
LOCATION. THIS HAS ALLOWED SHOWERS AND THUNDERSTORMS TO AFFECT THE
EASTERN AREAS MORE THAN FORECAST THE PAST FEW DAYS. WITH UPPER LOW
AND TROUGH AXIS NEAR THE NM/TX BORDER AND DISTURBANCES TO MOVE NORTH
ACROSS OUR REGION...WILL NOT DEVIATE MUCH FROM PAST COUPLE OF DAYS
AS THIS FEATURE WILL REMAIN NEARLY STATIONARY. THERE IS ENOUGH
INSTABILITY AND MOISTURE TO HANG ON TO AT LEAST A SLIGHT CHANCE OF
THUNDERSTORMS TODAY. CHANCES FOR RAIN WILL INCREASE THROUGH THE
SHORT TERM PERIOD. THERE IS A CHALLENGE THIS MORNING IN DECIDING
WHICH MODEL WILL BE MORE CORRECT IN THE POSITION OF THE FRONTAL
BOUNDARY THROUGH SATURDAY. BELIEVE IT WILL MAKE IT INTO THE NORTHERN
COUNTIES FRIDAY MORNING SOMETIME. PROBLEM COMES IN DECIDING WHAT TO
DO WITH TEMPERATURES. WILL BUMP UP TEMPS SLIGHTLY IN THE SOUTHERN FA
IN CASE FRONT NEVER DOES PUSH INTO THIS AREA. 850 TEMPS INDICATE ON
BOTH THE AVN AND ETA THAT KEEPING FRONT IN THE NORTHERN FA IS
REASONABLE. WILL LOOK AT THE MESOETA WHEN IT COMES IN TO SEE IF IT
IS CONSISTENT WITH THIS THINKING. HOPEFULLY THE COMBINATION OF THE
FRONT AND UPPER LOW WILL BRING A GOOD CHANCE OF RAIN ACROSS THE
WHOLE AREA. FINGERS ARE STILL CROSSED.
