Severe Thunderstorm Warning 221, NWS Midland/Odessa, TX

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
207 PM CDT TUE JUN 15 2004

.SHORT TERM...
UPPER RIDGE WILL MAINTAIN ITS STRENGTH FOR THE SHORT TERM OVER NRN
MEXICO INTO MOST OF THE FA.  THAT WILL ALLOW HOT TEMPERATURES TO
PREVAIL ACROSS ALL OF THE CWA.  UPPER LEVEL TEMPERATURES WERE A BIT
COOLER THAN THEY WERE LAST NIGHT /26 DEGREES VERSUS 28 DEGREES/ OVER
MAF AT 850 MB WHICH MAY PRECLUDE WIDESPREAD 100 DEGREE TEMPERATURES.
LOOKING FOR UPPER 90S TO NEAR 100 FOR MOST OF THE FA WITH THE
EXCEPTION OF THE TYPICAL HOT SPOTS SUCH AS WINK.

PRECIP PROBS ARE THE BIG QUESTION.  ETA AND GFS HAD POOR
INITIALIZATION THIS MORNING WITH UPPER LEVEL FEATURES.  ETA TENDED TO
MAKE THE RIDGE STRONGER THAN REALITY WHILE THE GFS MADE THE LOW OVER
THE TX COAST STRONGER.  AN OUTFLOW BOUNDARY AS PER SATELLITE IMAGERY
IS HEADED SWWD OVER THE KLUB CWA...COUPLED WITH THE UPPER LEVEL LOW
TO THE EAST AND WEST OF THE RIDGE...MAKES FOR AN INTERESTING
FORECAST.  MEANWHILE...THE TROPICAL LOW TO THE EAST CONTINUES ITS WWD
PUSH DESPITE THE MODEL/S BEST EFFORTS TO KEEP IT CONTAINED.  WILL
INCREASE POPS FOR TONIGHT AND ADD THE CHANCE OF ISOLD PRECIP TO OCCUR
ALONG THE ADVANCING DRYLINE THANKS TO THE INCREASED MOISTURE
CONVERGENCE ALONG IT.  EXPECT ISOLD THUNDERSTORMS TO FORM OVER THE
HIGHER TERRAIN OF THE DAVIS MOUNTAINS THANKS TO THE STRONG SURFACE
HEATING AND INCREASED UPPER MOISTURE.

.LONG TERM...
UPPER RIDGE WILL CONTINUE TO BE THE DOMINANT FEATURE THROUGH THE NEXT
FEW DAYS...NOT TO MENTION THE WEEKEND.  STRENGTH AND TIMING OF MAINLY
WEAK SHORTWAVE TROUGHS AROUND AND UNDER THIS RIDGE WILL BE DIFFICULT
TO LATCH ON TO.

UPPER RIDGE REBOUNDS OVER AREA WEDNESDAY AFTER A BRIEF WEAKENING
TODAY.  MODELS IN DECENT AGREEMENT AS FAR AS STRENGTHENING THE RIDGE
MORE THURSDAY AND KEEPING IT THAT WAY THROUGH SATURDAY...WHILE ZONAL
FLOW PREVAILS FURTHER NORTH.  CURRENT LOW LEVEL BOUNDARY OVER THE
WESTERN LOW ROLLING PLAINS EARLY THIS AFTERNOON WILL RETREAT NORTH
WEDNESDAY...SO DRYLINE WILL BE THE ONLY LOW LEVEL FOCUS.  INCLUDED
ISOLATED TSRA ALONG THE DRYLINE WEDNESDAY AS A PLETHORA OF WEAK
SHORTWAVES PROGGED TO SWIRL AROUND AND UNDER RIDGE...WHICH WILL
COINCIDE WITH SFC LI/S OF -5 TO -6 C...LAPSE RATES OF 8.5 TO 9
C/KM...AND SBCAPES AROUND 2000 J/KG.  MAY NOT SEE ANYTHING DEVELOP
DUE TO STRENGTH OF THE RIDGE...BUT ISOLATED POPS REFLECT THIS
UNCERTAINTY.

TEMPERATURES WILL BE JUST AS HOT OR SLIGHTLY LESS THAN MONDAY.
BASICALLY TOOK A DEGREE OR TWO OFF FOR THURSDAY AND FRIDAY FOR
FLUCTUATIONS IN THE UPPER RIDGE AND POSITION OF THE H85 THERMAL
RIDGE...BUT OVERALL HOT TEMPERATURES WILL BE THE RULE.

THURSDAY AND FRIDAY LOOK FAIRLY SIMILAR TO WEDNESDAY...BUT WITH THE
ADDED CHALLENGE OF WHETHER ANOTHER OUTFLOW ENHANCED BOUNDARY WILL
MAKE IT INTO THE CWA THURSDAY AFTERNOON A LA ETA.  WILL KEEP A
SLIGHT CHANCE OF TSRA FOR THIS EVENTUALITY SEEING AS HOW AN MCS IN
THE PLAINS WEDNESDAY NIGHT LOOKS VIABLE AND TODAY/S BOUNDARY MADE IT
INTO THE WESTERN LOW ROLLING PLAINS.  IF THE BOUNDARY DOES MAKE IT
INTO THE AREA THURSDAY...IT SHOULD RETREAT NORTH AND EAST FRIDAY.
THEREFORE...HAVE LEFT ISOLATED POPS ALONG MAINLY THE HIGHER TERRAIN
AS H85 MOISTURE INDICATED TO BE THAT FAR WEST AND CONVERGENCE ALONG
THE DRYLINE WILL BE WEAK.  RIDGE ALOFT MAY SQUELCH ANY ACTIVITY...
HENCE THE LOW POPS.

RIDGE REMAINS OVER THE AREA THROUGH THE WEEKEND...BUT WEAKENS A
LITTLE MORE BY DAY 6 AND 7.  TEMPERATURES ALREADY IN FORECAST LOOK
GOOD SO DID NOT FIDDLE WITH THEM MUCH.  GFS INDICATING A WEAK UPPER
TROUGH MOVING INTO THE AREA LATE MONDAY/TUESDAY...BUT ECMWF DEVOID
OF THIS FEATURE.  THEREFORE...WILL LEAVE THE ISOLATED POPS IN THE
DAVIS MOUNTAINS.
