AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LUBBOCK TX
227 AM CDT SUN JUN 16 2013

.SHORT TERM...
UA RIDGING STRETCHING FROM NERN OLD MEXICO /WHERE THE CENTER IS
LOCATED/ TO NEAR THE NW PACIFIC CONUS HAS RESULTED IN WNW FLOW
ALOFT. FURTHER AMPLIFICATION LATER THIS EVENING WILL VEER FLOW CLOSE
TO NW FLOW ALOFT...AND THE IMPORTANCE OF THIS WILL BE EXPLAINED
SHORTLY. LOOKING AT THE SFC...LIGHT SERLY SFC WINDS AND A 20-30 KT
LLJ ENSUED EARLY THIS MORNING ...THUS CAUSING MOIST LOW LEVELS TO
PERSIST /DEWPOINTS IN THE 60S/. THE MUCH DRIER AIR WAS NOTED ACROSS
CENTRAL/EASTERN NEW MEXICO. RADAR ANALYSIS DISPLAYED A SMALL COMPLEX
OF STORMS THAT HAS DEVELOPED ACROSS THE OKLAHOMA PANHANDLE THANKS IN
PART TO AN EMBEDDED WEAKNESS IN THE FLOW ALOFT. PRECIP HAS COMMENCED
TO DEVELOP ALONG THE SOUTHWARD PERIPHERY OF THE COMPLEX...WHICH
COULD NEAR THE SRN TEXAS PANHANDLE...BEFORE IT FINALLY DWINDLES
LATER THIS MORNING.

THIS AFTN...MOIST LOW LEVELS WILL ENDURE AND THEREFORE PROGGED PWATS
AOA 1.00 INCH WILL EXIST. THE NEARBY UA RIDGE WILL SUPPORT AN UPTICK
IN HEIGHT FIELDS AND HENCE...TEMPS WARMING TO SLIGHTLY ABOVE NORM
/MID TO UPPER 90S/. A SFC TROUGH DRAPED FROM NE TO SW ACROSS
NEW MEXICO...WILL BE THE FOCUS FOR CI. AS PREVIOUSLY
MENTIONED...FLOW ALOFT VEERING SLIGHTLY TO THE NW IS IMPORTANT
BECAUSE THIS IS A FAVORABLE DIRECTION FOR NEW MEXICO STORMS BEING
CAPABLE OF IMPACTING THE CWA. WITH THE BEST MID-LEVEL THETA-E AXIS
AND MID-LEVEL INSTABILITY EXPECTED TO SETUP ACROSS THE CWFA /ALONG
WITH EMBEDDED IMPULSES AND THE WNW FLOW ALOFT/...IT IS NO WONDER
THAT MODEL SOLUTIONS SHOW STORMS MOVING FROM WEST TO EAST ACROSS THE
REGION THIS AFTN-TONIGHT. GUSTY WINDS AND SMALL HAIL CAN NOT BE
RULED OUT GIVEN STEEPENING LAPSE RATES AND 2.0 KJ/KG OF MID-LEVEL
CAPE...BUT WITH THE ABSENCE OF A NOTABLE LARGE SCALE ASCENT
MECHANISM...SEVERE POTENTIAL WILL LIKELY BE LIMITED. FORECAST
SOLUTIONS SHOW AN MCS MOVING SE ACROSS SW KANSAS...POSSIBLY BRUSHING
ACROSS THE WESTERN PANHANDLES AND THE FAR SERN TEXAS PANHANDLE BY
THE END OF THE SHORT TERM PERIOD. WITH 1.00 INCH PWATS...ONE WOULD
THINK THAT MODERATE-HEAVY RAINFALL WILL BE PLAUSIBLE.
HOWEVER...ADEQUATE SPEEDS ALOFT IS EXPECTED AND THEREFORE THE
OVERALL STORM MOTION SHOULD NOT BE TERRIBLY SLOW.

&&

.LONG TERM...
STILL LOOKING LIKE PRETTY GOOD RAIN CHANCES MONDAY AND TUESDAY AS
WEAK...FLAT UPPER RIDGING WITH WEST TO WNW FLOW ALOFT COMBINED
WITH A FRONTAL BOUNDARY THAT IS EXPECTED TO STALL IN THE FCST AREA
SHOULD BE CONDUCIVE TO AT LEAST STORMS ROLLING IN FROM THE HIGH
TERRAIN OF ERN NM AND POSSIBLY ALSO FORMING ALONG THE FRONT. CHC
POPS CONTINUE TO LOOK FINE WITH A NUDGE UPWARDS FOR POPS MONDAY
NIGHT AS CONFIDENCE HAS INCREASED FURTHER.

TRANSITION THEN OCCURS WEDNESDAY AS UPPER RIDGING AMPLIFIES OVER
THE SRN AND CNTL PLAINS IN RESPONSE TO A TROUGH MOVING INTO THE
NWRN CONUS. AS A RESULT SHOULD SEE STORMS REMAIN ON THE WRN
PERIPHERY OF THE RIDGE TOWARD THE MOUNTAINS OF CNTL NM FROM
MIDWEEK INTO NEXT WEEKEND. TEMPS SHOULD WARM TO THE MIDDLE TO
UPPER 90S WITH SOME TRIPLE-DIGIT READINGS NOT OUT OF THE
QUESTION PARTICULARLY TOWARD FRIDAY AND SATURDAY WHEN THE RIDGE IS
PROGGED TO BE AT ITS STRONGEST POINT.
