Severe Thunderstorm Warning 66, NWS Midland/Odessa, TX

AREA FORECAST DISCUSSION

350 PM CDT SAT MAY 26 2001

SHORT TERM...
NOT MUCH GOING ON AT THE MOMENT.  WIDELY SCATTERED DIURNALLY DRIVEN
CONVECTION CONTINUES FROM THE DAVIS MOUNTAINS NORTH THROUGH THE
GUADALUPES...WITH ADDITIONAL CONVECTION NOTED OVER THE HIGHER TERRAIN
OF EAST CENTRAL NEW MEXICO.  LATEST SURFACE MESOANALYSIS SHOWS THE
LOW LEVEL THETAE RIDGE EXTENDING FROM THE TEXAS SOUTH PLAINS SOUTH
ACROSS THE WESTERN LOW ROLLING PLAINS AND INTO THE WESTERN EDWARDS
PLATEAU.  THE AIRMASS IS FAIRLY UNSTABLE WITH MUCAPES ABOVE 2500 J/KG
ACROSS THE EASTERN CWA...AND VERY LITTLE CIN REMAINS.  RIGHT NOW IT
LOOKS LIKE THE CONVECTIVE MODE IS MULTICELLULAR GIVEN THE LARGE LARGE
SURFACE T/TD SPREADS (INDICATIVE OF HIGH LFC'S...STRONGER SUBCLOUD
DIABATIC COOLING...ETC ETC) AND WEAK MID LEVEL WINDS.  WE MAY SEE A
FEW STORMS TRY TO POP OUT ON THE PLAINS LATER THIS AFTERNOON...BUT
THE BEST CHANCES WILL BE LATER THIS EVENING AS THE NOCTURNAL LOW
LEVEL JET KICKS IN AND INCREASES FORCING SOMEWHAT.  MUCH LIKE LAST
NIGHT...WE SHOULD SEE SOME MULTICELL CLUSTERS GIN UP OVER OUR
NORTHWESTERN ZONES NORTH INTO EAST CENTRAL NEW MEXICO AND TRANSLATE
SOUTHEAST ACROSS THE PERMIAN BASIN AND WESTERN LOW ROLLING PLAINS
LATE TONIGHT.  WILL RUN THE HIGHEST POPS OVER NORTHEASTERN ZONES
WHERE BETTER FORCING AND MOISTURE EXIST...WITH LESSER POPS FURTHER
SOUTH AND WEST.  EXPECT ISOLATED CONVECTION OVER THE HIGHER TERRAIN
OUT WEST WILL DIMINISH AROUND SUNSET.  OTHER THAN VARIABLE AND GUSTY
WINDS AND MVFR VSBYS INVOF CONVECTIVE ACTIVITY...NO AVIATION CONCERNS
ARE EXPECTED OVERNIGHT ACROSS THE CWA.

LONG TERM...
THE MODELS APPEAR REASONABLY INITIALIZED THIS MORNING...AND HAVE
NO REAL HEARTBURN OVER THEIR SOLUTIONS.  ALL INDICATE A MARKED
INCREASE IN THE EML OVER THE REGION AS H7 TEMPS WARM TO WELL ABOVE
12C.  THE GRADUAL FILLING OF THE PERSISTENT MIDWESTERN CLOSED LOW AND
INCREASING SHORTWAVE RIDGING OVER THE SOUTHERN PLAINS WILL KEEP THE
BEST DYNAMICS WELL TO THE NORTH OF THE REGION...AND THERE DOES NOT
APPEAR TO BE MUCH IN THE WAY OF LOW LEVEL FORCING OROGRAPHY TO DRIVE
PARCELS THROUGH THE STRENGTHENING CAP.  THUS HOT AND DRY CONDITIONS
ARE FORECAST THROUGH THE REMAINDER OF THE MEMORIAL DAY WEEKEND.
TEMPERATURES SUNDAY AND MONDAY SHOULD CLIMB TO NEAR OR ABOVE THE
CENTURY MARK ACROSS MOST LOCATIONS.  THE COMBINATION OF THE DRY AND
WARM CONDITIONS AND SOUTHWEST WINDS OF 15 TO 25 MPH NECESSITATE A
FIRE WEATHER WATCH FOR THE GUADALUPES SUNDAY.

REAL LONG TERM...
MRF ENSEMBLES CONTINUE THE TREND OF INCREASING TROUGHINESS ACROSS
THE WESTERN CONUS.  AFTER DRY AND WARM CONDITIONS EARLY NEXT WEEK...
WE SHOULD SEE AN INCREASE IN PRECIP CHANCES TOWARD THE END OF THE
WORK WEEK.  TEMPERATURES SHOULD BE AT OR SLIGHTLY ABOVE NORMAL FOR
LATE MAY/EARLY JUNE.

THAT'S A WRAP...GOALS AGAINST AVERAGE FOLLOW...70.
