AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
148 PM CDT THU MAY 24 2007

.SHORT TERM...
UPPER LEVEL TROUGH OVER THE SOUTHWESTERN CONUS MOVE VERY SLOWLY TO
THE EAST.  SHORTWAVES ARE ROTATING AROUND THE SOUTHERN END OF THE
TROUGH AND ARE MOVING ACROSS THE CWA.  AT THE SURFACE...A COLD FRONT
IS MOVING ACROSS THE CENTRAL CWA THIS AFTERNOON.  THE FRONT IS
BRINGING COOLER TEMPERATURES AND INCREASED MOISTURE TO THE REGION.

THE FRONT IS EXPECTED TO CONTINUE MOVING SOUTH THIS AFTERNOON
BECOMING STATIONARY OVER NORTHERN BREWSTER AND PRESIDIO COUNTIES
THIS EVENING.  LIFT ASSOCIATED WITH THE FRONT WILL CONTINUE TO
PRODUCE SCATTERED THUNDERSTORMS ALONG AND BEHIND THE FRONT.

ISENTROPIC UPGLIDE AND THE UPPER LEVEL DISTURBANCES WILL ENHANCE THE
THUNDERSTORM ACTIVITY WITH A CONVECTIVE COMPLEX POSSIBLY DEVELOPING
OVER THE UPPER TRANS PECOS REGION AND PERMIAN BASIN LATE TONIGHT.
WITH CAPES IN THE 1500 TO 2000 RANGE AND BULK SHEAR VECTORS OF 20 TO
30 KTS SOME OF THE STORMS MAY APPROACH SEVERE LIMITS THIS AFTERNOON
AND EVENING.  HOWEVER WITH PWATS OF AROUND 1 INCH...THE GREATEST
THREAT WILL BE HEAVY RAINFALL AND POSSIBLE FLOODING.

STRONG WINDS ARE EXPECTED IN THE GUADALUPE MOUNTAINS WITH GAP WINDS
ASSOCIATED WITH THE FRONT AFFECTING THAT AREA.  WILL KEEP WINDS JUST
BELOW WARNING CRITERIA WITH WINDS OF NEAR 35 MPH WITH GUSTS TO NEAR
50 MPH.  ELSEWHERE NORTH TO NORTHEAST WINDS OF 15 TO 25 MPH ARE
EXPECTED.  TEMPERATURES WILL BE MAINLY IN THE 50S AND 60S TONIGHT AS
THE COOL AIRMASS CONTINUES TO SETTLE INTO THE AREA.

.LONG TERM...
WITH UPPER TROUGH WEST OF THE REGION AND A FRONTAL BOUNDARY ACROSS THE
AREA WILL CREATE THE POTENTIAL FOR STORMS THROUGH THE WEEKEND.
SOME AREAS MAY RECEIVE LOCALLY HEAVY RAIN... WHILE OTHER AREAS
RECEIVE VERY LITTLE.  NOT LOOKING FOR MUCH IN THE WAY OF SEVERE
WEATHER.  MODELS NOT IN AGREEMENT AS TO LOCATION FOR HEAVIEST
RAIN.  WILL LEAN TOWARD HPC QPF FORECAST WHICH FAVORS THE NORTHEAST
PERMIAN BASIN/WESTERN LOW ROLLING PLAINS FOR THE HIGHEST RAINFALL.
ACTUAL HPC TOTALS LOOK A LITTLE HIGH... BUT COULD SEE 2 TO 3
INCHES OF RAIN FROM THE SHORT TERM THROUGH THE WEEKEND EAST OF A
GAIL TO BIG SPRING LINE.  12Z MAF SOUNDING HAD PW OF 0.85 INCH WITH
MODEL SOUNDINGS SHOWING PW INCREASING OVER 1 INCH NEXT FEW DAYS.
WILL MENTION LOCAL FLASH FLOODING POTENTIAL IN THE HWO.

FRIDAY SHOULD START WITH THE FRONT SITTING ACROSS THE CENTRAL PERMIAN
BASIN WHICH MAY HELP STORMS TO TRAIN ALONG IT.  AS EASTERLY SURFACE FLOW
RETURNS TO THE SOUTHEAST... THE FRONT SHOULD LIFT NORTHWARD.  HOWEVER
RAIN COOLED AIR FROM CONVECTION COULD DELAY ITS NORTHWARD MOVEMENT.  GFS
DEVELOPS AN MCS IN THE SHORT TERM... AND DEVELOPS ANOTHER MCS FRIDAY NIGHT
MOVING SOUTHWARD ACROSS SOUTHEASTERN NEW MEXICO AND OVER THE MOUNTAINS
OF WEST TEXAS.  WILL KEEP HIGHEST POPS FRIDAY ACROSS PERMIAN BASIN NEAR
THE FRONT... SHIFTING THEM WEST OVERNIGHT FOR THE MCS.  AS A NUMBER OF
WEAK DISTURBANCES TRACK ACROSS THE AREA... WILL KEEP CHANCE POPS THROUGH
SUNDAY AND FAVOR DEVELOPMENT OVER WESTERN MOUNTAINS.  LOW POPS MONDAY.

TEMPERATURES LOOK TO STAY BELOW NORMAL DUE TO CLOUDS AND RAINFALL INTO
EARLY NEXT WEEK.  UPPER RIDGE BUILDS IN FROM THE WEST TUESDAY RESULTING
IN HIGHS NEAR NORMAL AND DECREASING RAIN CHANCES... BUT THEN ANOTHER COLD
FRONT IS EXPECTED ON WEDNESDAY KNOCKING DOWN HIGHS THROUGH THE END OF THE
WEEK.
