AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
254 PM CDT TUE AUG 31 2004

.SHORT TERM...
AN UPPER LEVEL LOW REMAINS CENTERED ACROSS WEST TEXAS EARLY THIS
AFTERNOON. A COUPLE OF MESOSCALE CONVECTIVE VORTICES (MCV/S) ARE
NOTED ON VISIBLE SATELLITE...ONE NEAR ANDREWS AND ANOTHER JUST EAST
OF PECOS. CONVECTION CONTINUES TO FIRE ACROSS THE LOWER TRANS PECOS
AND SOUTHERN PERMIAN BASIN AT 18Z...WITH NEW DEVELOPMENT NOTED
ACROSS THE NORTHWEST PERMIAN BASIN AND THE SOUTHEAST NEW MEXICO
PLAINS.

WILL CONTINUE WITH RELATIVELY HIGH POPS THIS EVENING...ESPECIALLY
FROM THE PERMIAN BASIN SOUTHWEST THROUGH THE DAVIS MOUNTAINS/BIG
BEND AREA. WILL KEEP 30-40 PCT CHANCES OVER THE REMAINDER OF THE
AREA. OTHERWISE...MADE JUST A FEW MINOR CHANGES TO THE PREVIOUS SET
OF GRIDS TONIGHT...MAINLY TO OVERNIGHT SKY COVER AND LOWS.

.LONG TERM...
THE 850 MB THETA-E AXIS IS EXPECTED TO SHIFT WESTWARD ON
WEDNESDAY...AS WILL THE GREATEST RAIN CHANCES.  HOWEVER...BOTH THE
GFS AND ETA ARE IN AGREEMENT IN KEEPING A WEAK MID LEVEL SHEAR AXIS
OVER THE TEXAS PERMIAN BASIN.  SO WHILE THE BEST CHANCES OF RAIN
WILL BE OVER THE MOUNTAINS...HAVE OPTED TO KEEP SLIGHT CHANCE POPS
IN FOR THE REMAINDER OF THE COUNTY WARNING AREA ON WEDNESDAY.

RAIN CHANCES DIMINISH CONSIDERABLY BOTH THURSDAY AND FRIDAY AS
SURFACE PRESSURE FALLS OVER THE NORTHERN PLAINS RESULT IN MORE
SOUTHERLY SURFACE FLOW ACROSS WEST TEXAS.

A COLD FRONT IS EXPECTED THIS WEEKEND. FOR NOW I HAVE MADE SLIGHT
ADJUSTMENTS TO THE POP AND SKY GRIDS FOR THIS FEATURE.
OVERALL...CHANGES TO THE CURRENT FORECAST ARE MINOR AS WEATHER LOOKS
REASONABLY QUITE THROUGH MUCH OF THE EXTENDED FORECAST.
