AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
255 PM CDT THU MAY 31 2007

.DISCUSSION...
REMNANTS OF YESTERDAY/S COLD FRONT STILL LINGERING OVER THE AREA...
BUT HAS BECOME FAIRLY DIFFUSE THIS AFTERNOON.  THINK THE HIGHER
DEWPOINTS THAT EXTEND ACROSS THE PERMIAN BASIN AND INTO SOUTHEAST
NEW MEXICO BEST GUESSTIMATE ON POSITION AT 19Z/31.  ALOFT...A
FLATTENED UPPER RIDGE EXTENDED OVER THE CWA WHICH HAS BEEN KEEPING
CONVECTION AT BAY SO FAR.

ONE SHORTWAVE TROUGH OVER ARIZONA...IF NOT ONE PRECEDING IT OVER
NORTHERN MEXICO...ARE PROGGED TO MOVE INTO THE AREA THIS EVENING
AROUND THE NORTHERN PERIPHERY OF SAID RIDGE.  THESE SHORTWAVE
TROUGHS WILL LIKELY TEMPER OR ELIMINATE THE CAP OVER THE ABOVE AREAS
AS THEY APPROACH...SO THINK WE/LL SEE CONVECTION DEVELOP FROM NORTH
OF THE DAVIS MOUNTAINS OR THE UPPER TRANS PECOS INTO SOUTHEAST NEW
MEXICO LATE THIS AFTERNOON AND EARLY THIS EVENING.  SINCE SHEAR WILL
INCREASE TO 30 TO 40 KT...CAPES WILL BE IN THE VICINITY OF 2500
J/KG...MID LEVEL LAPSE RATES WILL BE AROUND 8 C/KM...AND THE FLOW
ALOFT BECOMES MORE DIFFLUENT AS THE UPPER RIDGE FLATTENS MORE THINK
SOME OF THESE STORMS COULD BE SEVERE.  LARGE HAIL AND DAMAGING WINDS
WILL BE THE PRIMARY THREATS...ALONG WITH HEAVY RAIN AND POSSIBLE
FLASH FLOODING OVER THE NORTHERN CWA THIS EVENING...IF NOT
OVERNIGHT.  HAVE MENTIONED SEVERE STORMS IN THE ZONES AND WILL
INCLUDE IN THE HWO.  THUNDERSTORMS COULD CONGLOMERATE INTO AN
MCS...POSSIBLY TRAVELING ACROSS THE NORTHERN CWA ON THE NOSE OF A 50
KT H85 JET.  THE LOCATION OF ANY MCS WILL DEPEND ON WHERE THE
AFOREMENTIONED REMNANT COLD FRONTAL BOUNDARY ALIGNS OVERNIGHT.  WILL
CARRY LOW ORDER CHANCE POPS DUE TO THE UNCERTAINTY...WITH THE
HIGHEST OVER THE NORTHERN CWA.

A TIGHTENING SURFACE PRESSURE GRADIENT WILL KEEP WINDS UP MOST
LOCATIONS OVERNIGHT...AND ALONG WITH THE EXPECTED CLOUD COVER...KEEP
MINIMUM TEMPERATURES AROUND FIVE DEGREES ABOVE NORMAL VALUES.
WILL BEGIN THE LONG TERM WITH A RIDGE BUILDING OVER BAJA AND AN
UPPER LEVEL LOW OVER SOUTH DAKOTA/NEBRASKA.  THIS WILL LEAVE THE
MIDLAND AREA IN THE NORTHWEST FLOW FAVORABLE FOR SHORTWAVES TO
TRANSLATE THROUGH THE AREA WITH SOME FREQUENCY.  THIS NORTHWEST FLOW
REGIME WILL CONTINUE THROUGH THE WEEKEND WITH THE RIDGE STARTING TO
FLATTEN OUT ON TUESDAY.

WITH SHORTWAVES CONSISTENTLY COMING THROUGH THE AREA...THERE WILL BE
A SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS MOST OF THE COMING DAYS
IN AT LEAST ONE PART OF THE WARNING AREA.  IN THE SHORT TERM THERE IS
STILL QUITE A BIT OF DISAGREEMENT BETWEEN THE NAM AND THE GFS ON
LOCATIONS OF PRECIPITATION.  THE NAM HAS VERIFIED BETTER WITH PRECIP
LOCATIONS OVER THE PAST FEW DAYS SO WILL GO WITH MORE OF A NAM
SOLUTION FOR LOCATIONS AND AMOUNTS OF QPF.  FRIDAY AND SATURDAY...
CONDITIONS ARE SUCH THAT ANY STORMS THAT DO DEVELOP HAVE THE
POTENTIAL TO BECOME SEVERE...WITH GOOD CAPE...NEGATIVE LI/S...AND
CLOSE TO 50KTS BULK SHEAR THANKS TO A STRONG LLJ THAT WILL KICK UP
OVERNIGHT FRIDAY.

BEYOND SATURDAY...AM LIMITED TO THE SOMEWHAT MORE ERRATIC GFS DATA.
A WEAK COLD FRONT WILL MOVE THROUGH SOMETIME BETWEEN SUNDAY EVENING
AND MONDAY EVENING.  IT IS DIFFICULT TO DETERMINE THE EXACT TIMING
OF IT AT THIS POINT.  HOWEVER...THROUGH THE REST OF THE WEEKEND AND
INTO THE BEGINNING OF THE WORK WEEK THERE WILL BE A SLIGHT CHANCE OF
SHOWERS AND THUNDERSTORMS.  CAN ASSUME THAT SOME OF THIS WILL BE ON
THE FRONT AS IT MOVES INTO THE AREA.  BY TUESDAY AND WEDNESDAY WHEN
THE RIDGE BEGINS TO FLATTEN OUT...CHANCES OF PRECIPITATION WILL
DIMINISH SOMEWHAT.

THE REMAINDER OF THE FORECAST WILL LIKELY REMAIN UNCHANGED WITH
PERHAPS SOME MINOR ADJUSTMENTS TO TEMPERATURES.  GUIDANCE IS STILL
OVERREACHING ON THE TEMPERATURES SOMEWHAT SO WILL GO A DEGREE OR TWO
BELOW AT THIS POINT.
