AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
105 PM CDT SAT JUL 9 2005

.SHORT TERM...
UPPER RIDGE WILL CONTINUE OVER THE CENTRAL U.S. AS A TROUGH MOVES
ONTO THE NORTHWEST.  DAYTIME HEATING... OROGRAPHIC LIFT... OLD
BOUNDARIES... AND WEAK SHORTWAVES WILL COMBINE FOR ANOTHER ROUND OF
CONVECTION.  LAST NIGHTS STORMS HAVE JUST RECENTLY DIED OUT BUT AS
OF EARLY AFTERNOON DAVIS MOUNTAINS ALREADY LOOKING RIGHT FOR FIRING.

CLOUD COVER FROM LAST NIGHTS CONVECTION HELPED TO HOLD DOWN TEMPS
THROUGH THE MORNING... BUT ONCE THE SUN BROKE THROUGH TEMPS HAVE BEEN
QUICKLY ON THE RISE.  MODELS SHOW INCREASING MID CLOUDS OVERNIGHT
WITH STORMS SO SHOULD BE ANOTHER WARM NIGHT.

THE MODELS DID A GOOD JOB DEVELOPING THE PRECIP LAST NIGHT AS FAR AS
LOCATION AND LOOK SIMILAR TODAY AS THEY DEVELOP STORMS OVER THE
HIGHER ELEVATIONS OUT WEST THIS AFTERNOON AND SPREAD THEM EASTWARD
THROUGH THE EVENING.  WEAK SHORTWAVES ROLLING AROUND THE RIDGE WILL
HELP DEVELOP THESE STORMS AND CONTINUE THEM OVERNIGHT.  SURFACE
DEWPOINTS IN THE 50S TO LOWER 60S AS LOW LEVEL MOISTURE ONLY
MODERATE... THE LAST MEASURED PRECIP AT MAF WAS 0.92 ON JUNE 3RD.

RADAR SHOWED A BOUNDARY MOVING NORTH THROUGH ANDREWS COUNTY AROUND
NOON AND THIS COULD BECOME A FOCUS FOR LATER STORM DEVELOPMENT.
ALSO SATELLITE SHOWS A MCV FROM LAST NIGHTS STORMS SPINNING OVER THE
SOUTH PLAINS... THIS COULD INFLUENCE THE AREA IF IT DRIFTS SOUTH BUT
APPEARS TO BE MOVING LITTLE.

.LONG TERM...
NORTHELY FLOW ALOFT CONTINUES THROUGH SUNDAY WITH SHORTWAVES
DROPPING SOUTH ON THE EAST SIDE OF UPPER RIDGE ESTENDING FROM
NORTHERN MEXICO INTO NEW MEXICO. ETA AND GFS BOTH DEPICT A
SLIGHTLY STRONGER DISTURBANCE DROPPING THROUGH THE SOUTH PLAINS
TO THE PERMIAN BASIN SUNDAY AFTERNOON. ETA IS PARTICULARLY STRONG
WITH THIS FEATURE...DEVELOPING SIGNIFICANT LIFT AND PRECIPITATION
PARTICULARLY AS IT DROPS SOUTH OF THE PERMIAN BASIN DURNIG
MAXIMUM HEATING. HAVE PLAYED UP POPS AND QPF MAINLY OVER THE
SOUTHERN CWA AND MOUNTAIN AREAS...WHERE UPSLOPE FLOW WILL
CONTRIBUTE TO LIFT.

BEYOND SUNDAY...MEDIUM RANGE MODELS CONSISTENT IN BUILDING UPPER
HIGH IN THE WEST INTO THE FOUR CORNERS AREA...RESULTING IN A
SHIFT TO NORTHEAST FLOW ALOFT. MOIST EASTERLY COMPONENT TO LOW LEVEL
WILL FAVOR ISOLATED TO SCATTERED MOUNTAIN CONVECTION THROUGH NEXT
WEEK. NORTHEAST STEERING FLOW SHOULD KEEP MOST PRECIPITATION OUT
OF THE PLAINS. THE FLY IN THE OINTMENT IS A WEAK COLD FRONT OR
SURFACE TROUGH THAT SINKS INTO THE FORECAST AREA WEDNESDAY...
WHICH COULD PROVIDE A FOCUS FOR A LITTLE MORE CONVECTION IN THE
PLAINS FOR THE SECOND HALF OF NEXT WEEK. FOR NOW...FORECAST WILL
DOWNPLAY THAT POSSIBILITY. AN ADDITIONAL FACTOR THAT COMES INTO
PLAY LATE IN THE FORECAST CYCLE IS THE POTENTIAL EFFECT OF
DENNIS REMNANTS. MODELS HAVE INCONSISTENTLY SHOWN THE NORTHEAST
PROGRESS OF DENNIS BEING HALTED BY A RIDGE BUILDING NORTH OF
THE SYSTEM. THOUGH RETROGRADING OF THE REMNANT UPPER LOW OF
THE STORM AS FAR AS WEST TEXAS IS NOT REAL LIKELY...IT WILL BE
SOMETHING TO WATCH FOR IN THE EXTENDED.

RETROGRESSION OF THE UPPER HIGH TO THE FOUR CORNERS AREA AND
SOUTHEAST LOW LEVEL FLOW SHOULD KEEP TEMPERATURES NEAR OR
POSSIBLY SLIGHTLY BELOW NORMALS THROUGH THE FORECAST PERIOD.
