AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
550 PM CDT FRI JUN 16 2006

.UPDATE...
UPDATING FORECAST TO INCLUDE ISSUANCE OF SEVERE THUNDERSTORM WATCH
NUMBER 494 UNTIL 2 AM CDT FOR EASTERN PORTIONS OF THE FORECAST
AREA PRIMARILY ALONG AND EAST OF A LAMESA...TO ODESSA...TO FORT
STOCKTON LINE...INCLUDING THE MIDLAND/ODESSA METRO AREAS. THE
PRIMARY THREATS FROM ANY SEVERE THUNDERSTORMS WILL BE DAMAGING
WINDS AND LARGE HAIL. DANGEROUS CLOUD TO GROUND LIGHTNING WILL
ALSO BE LIKELY.

&&

.PREV DISCUSSION... (ISSUED 219 PM CDT FRI JUN 16 2006)

SHORT TERM...
POTENT UPPER TROUGH AXIS NOW LOCATED IN CENTRAL COLORADO AND
NORTHERN NEW MEXICO AS PER WATER VAPOR IMAGERY AND CURRENT
MESOANALYSIS. THIS VIGOROUS SYSTEM WILL BE RESPONSIBLE FOR
NUMEROUS WEATHER THREATS THAT WILL CONTINUE INTO EARLY THIS
EVENING. AHEAD OF THE SYSTEM...A SHARPENING DRYLINE HAS DEVELOPED
FROM A HALFWAY TO MENTONE TO PECOS LINE AT 16/1700Z. SOUTHEASTERLY
WINDS AHEAD OF IT HAVE NOTICEABLY INCREASED SURFACE DEWPOINTS
ACROSS THE AREA WITH VALUES APPROACHING THE MID 60S IN MANY AREAS
ACROSS THE PERMIAN BASIN. THE SURFACE WINDS HOWEVER...HAVE
DECREASED SLIGHTLY IN STRENGTH AHEAD OF THE DRYLINE AS THE LLJ HAS
WEAKENED SOMEWHAT /PER THE JAYTON PROFILER/ WHILE THE PBL HAS
INCREASED IN HEIGHT. STEEPENING LAPSE RATES BY LATE AFTERNOON
COMBINED WITH THIS ESTABLISHED THETA-E RIDGE SHOULD ENHANCE THE
SEVERE THUNDERSTORM THREAT ACROSS THE CENTRAL AND EASTERN BASIN
AND ROLLING PLAINS LATER THIS AFTERNOON. 16/1200Z KMAF SOUNDING
INDICATES EXTRAORDINARY INSTABILITY /CAPE ABOVE THE LEVEL OF FREE
CONVECTION NEAR 5000 J/KG/ WHICH COULD BE REALIZED GIVEN THE
CURRENT EXPECTATIONS FOR MAXIMUM HEATING...HOWEVER THERE IS A
LARGE CAP /5 DEGREE/ THAT WILL NEED TO BE OVERCOME AT KMAF BEFORE
THE INSTABILITY CAN BE REALIZED. THE BIG QUESTION IS HOW FAR THE
DRYLINE MIXES EASTWARD BEFORE CONVECTIVE INITIATION CAN TAKE
PLACE.

CURRENT FORECAST PACKAGE IN THE GRIDS LOOKS ON TRACK AND WILL NOT
ADJUST IT MUCH.  THE MAIN THREAT WILL LIKELY REMAIN ACROSS THE
CENTRAL AND EASTERN PERMIAN BASIN AS WELL AS THE WESTERN ROLLING
PLAINS.  WHILE THE FREEZING LEVEL REMAINS HIGH ACCORDING TO THE
LATEST SOUNDING FROM KMAF...THE LARGE CAPE VALUES IN THE REGION OF
GREATEST POTENTIAL FOR HAIL GROWTH WILL SUPPORT LARGE STONES IF
CONVECTION INITIATES.  THEREFORE...ANY MELTING THAT MAY OCCUR SHOULD
NOT REDUCE THE HAIL THREAT BELOW SEVERE CRITERIA GIVEN THE LIMITED
MID-LEVEL MOISTURE CONTENT AS PER WATER VAPOR IMAGERY.  IN
ADDITION...STRONG WINDS ARE A POSSIBILITY AS 700-500 MB DIFFERENTIAL
THETA-E VALUES SHOW THE POTENTIAL FOR STRONG DOWNBURST WINDS.  DEEP
LAYER SHEAR VALUES INDICATE THAT SUPERCELLS MAY INITIALLY FORM ALONG
THE DRYLINE PROVIDED CONVECTIVE INITIATION TAKES PLACE WHILE LATER
DEVELOPING INTO A BROKEN LINE BEFORE EXITING THE CWA LATER THIS
EVENING.  AROUND 17/1200Z...A COLD FRONT SHOULD BE MAKING ITS WAY
THROUGH THE BASIN.  DO NOT EXPECT MUCH IN THE WAY OF PRECIPITATION
WITH THE FRONT INITIALLY.  ADDITIONALLY...NO RELIEF FROM THE HOT
TEMPERATURES ARE EXPECTED.  ABOUT THE ONLY THING OF SIGNIFICANCE
WILL BE A WIND SHIFT TO THE NORTH BY MORNING.

MEANWHILE...BEHIND THE DRYLINE...RELATIVE HUMIDITY VALUES HAVE
DROPPED BELOW 15 PERCENT ACROSS SOUTHEAST NEW MEXICO SOUTHWARD
ACROSS THE GUADALUPE MOUNTAIN CHAIN AND INTO THE TRANS PECOS.
PRECIPITATION CHANCES HERE HAVE BEEN ERASED.  RED FLAG CRITERIA HAS
ALREADY BEEN REACHED ACROSS MUCH OF THE HIGHLIGHTED AREA INDICATED
BY THE RED FLAG WARNING CURRENTLY IN EFFECT /LBBRFWMAF/.
OVERNIGHT...THE DECOUPLING OF THE PBL WILL RESULT IN A WESTWARD
SHIFT OF THE DRYLINE.  EXPECT RH RECOVERIES TO BE FAIR TO GOOD
ACROSS THE PERMIAN BASIN AND WORSE ACROSS THE PLAINS OF SOUTHEASTERN
NEW MEXICO SOUTHWARD THROUGH THE MARFA PLATEAU.

LONG TERM...
BOTH THE NAM AND GFS ARE IN DECENT AGREEMENT IN MOVING THE UPPER
LEVEL TROUGH ACROSS OUR CWA ON SATURDAY...INTO THE EASTERN HALF OF
TEXAS BY SUNDAY MORNING.  AN ASSOCIATED SURFACE BOUNDARY...WEAK
FRONT...IS EXPECTED TO EASE INTO THE AREA ON SATURDAY...BECOMING
QUASI-STATIONARY FROM THE ROLLING PLAINS ACROSS THE CENTRAL PERMIAN
BASIN AND INTO THE LOWER TRANS PECOS REGION.

NO REAL RELIEF IS EXPECTED FROM THE HEAT DUE TO THIS WEAK FRONTAL
BOUNDARY.  HOWEVER...THE BOUNDARY SHOULD SERVE AS THE FOCUS FOR
CONVECTIVE INITIATION ON SATURDAY AFTERNOON AND EVENING.  ON
SATURDAY...THE BEST INSTABILITY WILL BE OVER THE NORTHEAST PORTIONS
OF THE TEXAS PERMIAN BASIN...WHERE CAPE VALUES ARE EXPECTED TO BE IN
THE 2500 J/KG RANGE BY AFTERNOON.  WHILE SPEED SHEAR DOES NOT LOOK
TERRIBLY IMPRESSIVE FOR SATURDAY...THE SURFACE BOUNDARY WILL AID IN
BACKING WINDS AND INCREASING SR HELICITY VALUES.  HOWEVER WOULD
EXPECT THAT THE PRIMARY THREAT WILL REMAIN AS HAIL AND DAMAGING
WINDS WITH ANY SEVERE THUNDERSTORMS THAT DEVELOP.

BOTH THE NAM AND THE GFS SHOW THE SURFACE BOUNDARY PUSHING SOUTHWARD
SATURDAY AFTERNOON INTO THE LOWER TRANS PECOS AND STOCKTON PLATEAU
REGION BY EVENING.  THIS SEEMS REASONABLE BASED ON THE EXPECTATION
THAT DEVELOPING THUNDERSTORMS DURING THE EARLY AFTERNOON OVER THE
NORTHEAST CWA WILL PROVIDE AN EXTRA PUSH FROM THE NORTH.
THUS...HAVE ADJUSTED THE BEST SATURDAY EVENING RAIN CHANCES
SLIGHTLY FARTHER SOUTH INTO THE SOUTHEAST PORTIONS OF THE CWA.
WHILE THERE IS A SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS
ELSEWHERE OVER THE PERMIAN BASIN...SLIGHTLY LESS LOW LEVEL
MOISTURE AND LACK OF A FOCUS COULD BE ENOUGH HELP INHIBIT SHOWERS
AND THUNDERSTORMS FROM DEVELOPING TOO FAR WESTWARD.

AS THE SURFACE BOUNDARY BECOMES MORE DIFFUSE ON SUNDAY...THE UPPER
TROUGH SLIDES TO THE EAST...AND THE UPPER RIDGE TAKES HOLD AGAIN TO
THE WEST...RAIN CHANCES SHOULD DIMINISH SUNDAY THROUGH TUESDAY
ACROSS THE CWA.  ZONAL UPPER FLOW IN THE NORTHERN AND CENTRAL PLAINS
TOWARDS BY TUESDAY OF NEXT WEEK SHOULD RESULT IN A LEE SURFACE
TROUGH STRENGTHENING TUESDAY INTO WEDNESDAY EAST OF THE ROCKIES.
THIS SHOULD AID LOW LEVEL MOISTURE RETURN AGAINST THE MOUNTAINS BY
MID WEEK AND SLIGHTLY INCREASED RAIN CHANCES FOR THE DAVIS
MOUNTAINS.

FIRE WEATHER...
EXPECTED RED FLAG CONDITIONS OVER THE GUADALUPE MOUNTAINS...THE
SOUTHEAST NEW MEXICO PLAINS...AND THE DAVIS MOUNTAINS HAVE
VERIFIED AS THE DRYLINE HAS MIXED EASTWARD INTO THE SOUTH PLAINS
AND TEXAS PERMIAN BASIN. EXPECTATIONS ARE THAT THESE CONDITIONS WILL
PERSIST THROUGH 10 PM CDT TONIGHT. THUS...WILL CONTINUE WITH THE
RED FLAG WARNING THIS EVENING. PRIMARY INDICATIONS ARE THAT 20
FOOT WINDS WILL BE TOO WEAK OVER THE NEXT SEVERAL DAYS TO WARRANT
CRITICAL FIRE WEATHER CONDITIONS BEING REALIZED...THUS HAVE NOT
EXTENDED ANY FIRE WEATHER WATCHES INTO THE WEEKEND OR EARLY NEXT
WEEK.
