AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
221 PM CDT FRI JUN 1 2007

.DISCUSSION...
AN UPPER LEVEL RIDGE IS BEGINNING TO BUILD ACROSS WESTERN MEXICO AND
IN COMBINATION WITH THE UPPER LEVEL LOW CIRCULATING OVER SOUTH
DAKOTA WILL GRADUALLY TURN THE FLOW OVER MIDLAND TO NORTHWESTERLY
THIS AFTERNOON.  SEVERAL SHORTWAVES WILL TRANSLATE THROUGH THIS FLOW
LATE THIS AFTERNOON AND THIS EVENING.  AN 85-90KT UPPER LEVEL JET
WILL NOSE INTO THE AREA THIS AFTERNOON AS WELL...PROVIDING THE UPPER
LEVEL DYNAMICS FOR SEVERE STORMS TO DEVELOP.

A LOOK AT NAM BUFFER SOUNDINGS FOR KMAF SHOWS PLENTY OF INSTABILITY
/3500 J/KG SBCAPE/...MOISTURE /PWATS 180 PERCENT OF NORMAL/...AND
LIFT /WITH THE SHORTWAVES/...FOR NOT ONLY SHOWERS AND THUNDERSTORMS
TO DEVELOP BUT FOR SEVERE WEATHER TO OCCUR WITH THESE STORMS.  MID
LEVEL LAPSE RATES WILL BE BETWEEN 7.5 AND 8.5 DEGREE/KM THIS
AFTERNOON ACCORDING TO BOTH THE NAM AND THE GFS.  THIS IS ABOUT THE
ONLY AGREEMENT IN THE MODELS.  USING THE 12Z NAM...AS THE NAM HAS
BEEN MORE ACCURATE...SHOWERS AND THUNDERSTORMS WILL LIKELY DEVELOP
IN SOUTHEASTERN NEW MEXICO THIS AFTERNOON AND MOVE EAST WITH THE
EASTWARD MOVEMENT OF THE DRYLINE.  THE MAJORITY OF THESE STORMS WILL
REMAIN NORTH AND EAST OF THE PECOS RIVER.  THE NAM HAS THE DRYLINE
MOVING AS FAR EAST AS THE TX/NM BORDER BEFORE RETREATING WESTWARD
OVERNIGHT.  WHILE THERE IS NOT A LOT OF SPEED SHEAR...THERE IS QUITE
A BIT OF DIRECTIONAL SHEAR WITH SOUTHEASTERLY LOW LEVEL WINDS AND
WESTERLY WINDS AT 6KM.  THIS WILL RESULT IN 50-60KT 0-6KM BULK
SHEAR.  WITH DEWPOINTS IN THE MID 60S NORTH OF THE PECOS...LCL/S
WILL BE FAIRLY LOW AND COMBINED WITH THE SHEAR WILL BRING THE
POSSIBILITY OF A TORNADO OR TWO THIS AFTERNOON.  THIS WILL BE
ADDRESSED MORE IN THIS AFTERNOON/S HWO.

TONIGHT/S LOW TEMPERATURES WILL DEPEND ON AMOUNT AND DURATION OF
CLOUD COVER...STORMS STILL IN THE AREA...WIND SPEEDS...AND
DEWPOINTS.  BECAUSE OF STORMS EXPECTED IN THE NORTH WENT WITH MORE
OF A MET/MAVMOS SOLUTION FOR LOWS.  IT IS LIKELY THAT CLOUD COVER
WILL REMAIN ACROSS THAT AREA...WITH DEWPOINTS STAYING HIGH...AND
WIND SPEEDS AROUND THE STORMS AND AN APPROACHING BOUNDARY WILL KEEP
TEMPERATURES UP.  WEST OF THE PECOS...ON THE OTHER HAND...WENT WITH
MORE OF AN FWC SOLUTION BECAUSE OF THE LACK OF CLOUD COVER AND THE
LIKELIHOOD OF WINDS DROPPING OFF.

THE AREA WILL REMAINED SANDWICHED BETWEEN A PERSISTENT CUTOFF LOW/
UPPER TROUGH OVER THE NORTHERN PLAINS/GREAT LAKES...AND AN UPPER
LEVEL RIDGE OVER SOUTHWESTERN/CENTRAL MEXICO THROUGH THE WEEKEND.
THIS WILL ALLOW FOR A SERIES OF SHORTWAVE TROUGHS TO TRAVERSE THE
AREA DURING THIS TIME.  UNFORTUNATELY...PRECIPITATION CHANCES WILL
BE TIED TO THE PRESENCE...OR LACK...OF FRONTS/BOUNDARIES OVER THE
AREA.  THEREFORE...THE TIMING OF EACH ROUND OF PRECIPITATION WE SEE
WILL BE DIFFICULT TO SAY THE LEAST.  HAVE TENDED THE FORECAST TOWARD
THE NAM/ECMWF WHICH APPEAR TO HAVE PERFORMED BETTER LATELY
CONSIDERING THE MESOSCALE EFFECTS INVOLVED.

WILL KEEP A SLIGHT CHANCE OF THUNDERSTORMS GOING SATURDAY AS
EXPECTING AN OUTFLOW BOUNDARY TO STILL EXIST OVER THE AREA.
FLATTENED UPPER RIDGE WITH GENERAL NORTHWEST FLOW ALOFT OVER THE
AREA SATURDAY WILL ALLOW FOR ADDITIONAL SHORTWAVE TROUGHS TO
TRAVERSE THE CWA.  SINCE WE WILL CONTINUE TO HAVE A VERY MOIST LOW
LEVEL AIRMASS OVER THE CWA...IN ADDITION TO INCREASING UPPER LEVEL
MOISTURE... THINK POPS COULD BE RAISED FURTHER WHEN THE LOCATION OF
THE BOUNDARY BECOMES MORE EVIDENT.  THE POTENTIAL FOR A NOCTURNAL
MCS TO MOVE OVER THE CWA WILL EXIST BOTH SATURDAY AND SUNDAY
NIGHT...BUT AGAIN THE LOCATION OF ANY LOW LEVEL BOUNDARY WILL BE
TANTAMOUNT TO THE PLACEMENT OF POPS.  SINCE WE WILL CONTINUE TO HAVE
STIFF SOUTH/ SOUTHEASTERLY FLOW IN THE LOW LEVELS...HAVE KEPT THE
BETTER POPS ALONG THE NORTHERN CWA SATURDAY AND FURTHER SOUTH
SUNDAY.

EXPECT TO SEE A FRONTAL BOUNDARY MOVE INTO THE CWA SUNDAY AFTERNOON/
EVENING DUE TO THE PERSISTENT NORTHERLY FLOW ALOFT AROUND THE
AFOREMENTIONED CUTOFF LOW/EVENTUAL GREAT LAKES LONGWAVE TROUGH.
THIS IS IN PART THE REASON FOR THE HIGHER POPS BOTH SUNDAY NIGHT AND
MONDAY.  SEVERE STORMS WILL DEFINITELY BE POSSIBLE WITH EACH ROUND
OF THUNDERSTORMS SATURDAY THROUGH MONDAY AS INSTABILITY AND SHEAR
WILL REMAIN HIGH ENOUGH FOR ORGANIZED STORMS.  WILL MAKE A MENTION
IN THE HWO FOR THE POTENTIAL FOR LARGE HAIL AND DAMAGING WINDS WITH
EACH ROUND...BUT WILL NOT GET TOO FANCY CONSIDERING THE UNCERTAINTY
WITH THE LOCATION OF ANY BOUNDARIES.  BY TUESDAY...THINK A DRYLINE
WILL SET UP AS ANOTHER TROUGH SETTLES OVER THE WESTERN CONUS AND
FLOW ALOFT BECOMES MORE WESTERLY AND STRENGTHENS OVER THE CWA.
THEREFORE...INCLUDED A SLIGHT CHANCE OF THUNDERSTORMS OVER THE
EASTERN CWA TUESDAY AFTERNOON BEFORE MAKING THE REMAINDER OF THE
FORECAST DRY.  THIS AS PERSISTENT WESTERLY FLOW WILL LIKELY MIX THE
DRYLINE TO THE EASTERN FRINGE...OR EAST OF THE CWA.

THE ABOVE ALSO ENTAILED A CONTINUATION OF MORE NEAR NORMAL
TEMPERATURES THROUGH SATURDAY...BUT THEN COOLER THAN NORMAL
TEMPERATURES SUNDAY AND MONDAY.  AVE UNDERCUT MOST GUIDANCE ON
SATURDAY SINCE MOS HAS BEEN TOO WARM OF LATE.  REALLY UNDERCUT MOS
ON MONDAY AND TUESDAY AS THE GFS WAS NOT AS BULLISH BRINGING A FRONT
SOUTH INTO THE AREA AS THE NAM/ECMWF.  WENT CLOSER TO MEXMOS ON DAYS
6 AND 7 AS ABOVE NORMAL TEMPERATURES APPEAR MORE LIKELY WITH THE
EXPECTED FLOW ALOFT.
