AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LUBBOCK TX
321 PM CDT SAT AUG 25 2012

.SHORT TERM...
THE TAIL END OF THE SHORTWAVE TROUGH CONTINUED TO MOVE ENE ACROSS
THE SOUTHERN PLAINS THIS AFTERNOON. LOOKING AT THE SFC...GENERALLY
CLEAR SKIES HAVE ALLOWED FOR TEMPS TO WARM INTO THE UPPER 80S TO MID
TO UPPER 90S. A SFC TROUGH WAS DRAPED FROM NEAR MEMPHIS...TO
LITTLEFIELD TO NORTH OF PLAINS...THUS PROMOTING SFC CONVERGENCE.
WITH SFC-BASED CAPE OF 1.5-2.0 KJ/KG NOTED ACROSS THE SERN TEXAS
PANHANDLE COMBINED WITH THE SFC TROUGH...HAS RESULTED IN SCATTERED
SHOWERS AND THUNDERSTORMS NEAR SILVERTON AND TULIA THUS FAR.
INVERTED-V SOUNDING PROFILES...PWATS AOA 1.80 INCHES AND
APPROXIMATELY 20-25 KTS OF 0-6 KM BULK SHEAR ACROSS THE ERN ZONES
SUGGEST THE PROSPECT FOR SEVERE WIND GUSTS...BRIEF MODERATE RAINFALL
AND PERHAPS SMALL HAIL. THE BEST INSTABILITY AXIS IS EXPECTED TO
REMAIN ACROSS THE ERN SOUTH PLAINS THROUGHOUT THE AFTERNOON...AND AS
SUCH...ADDITIONAL DEVELOPMENT IS FAVORABLE THERE /SHOWERS HAVE
POPPED UP NORTH OF ASPERMONT/. HOWEVER...THE WESTERN PERIPHERY OF
THE SFC TROUGH CAN NOT BE RULED OUT AS ANOTHER LOCATION FOR PRECIP
DEVELOPMENT...WHICH IS EVIDENT PER THE AGITATED CU-FIELD NORTH AND
WEST OF PLAINS. ALTHOUGH THE BEST INSTABILITY IS ACROSS ERN
ZONES...STORMS ON THE CAPROCK WILL BE STILL BE CAPABLE OF PRODUCING
MODERATE RAINFALL /WEAK STEERING FLOW/ AND STRONG TO SEVERE WIND
GUSTS AS ABL MIXING TO NEAR 700 MB OCCURS.

THIS EVENING THROUGH TONIGHT...FORECAST SOLUTIONS SHOWED THE SFC
TROUGH PROGRESSING TOWARDS THE CENTRAL ZONES /WEAK WIND SHIFT TO THE
ENE/ BEFORE RETREATING TO THE SWRN TEXAS PANHANDLE THIS EVENING.
HOWEVER...A SECONDARY PUSH TOWARDS THE CENTRAL ZONES IS ANTICIPATED
TO OCCUR TONIGHT. THIS FRONTAL INTRUSION COMBINED WITH A 25-35 KT
SOUTHERLY LLJ AND SFC-BASED CAPE OF 1.0-2.0 KJ/KG WILL KEEP STORMS
AND THE AFOREMENTIONED THREATS GOING OFF THE CAPROCK TONIGHT WHERE
THE INSTABILITY IS HIGHEST...AND ALLOW STORMS TO DEVELOP ACROSS
CENTRAL AND SOUTHERN LOCALES ALONG BEST SFC CONVERGENCE.
TOMORROW...THE TAIL END OF THE SHORTWAVE WILL BE LOCATED JUST EAST
OF THE CWA AS AN UA RIDGE COMMENCE TO AMPLIFY ACROSS NEW MEXICO.
HOWEVER THE FRONTAL BOUNDARY WILL CONTINUE TO LINGER NEAR THE
CENTRAL ZONES AND PROVIDE A FOCUS FOR LATE MORNING/AFTERNOON SHOWER
AND THUNDERSTORM DEVELOPMENT...ESPECIALLY ACROSS PORTIONS OF THE
CENTRAL...SRN AND ERN LOCALES. CHANCES FOR STORMS WILL DECREASE FROM
NORTH TO SOUTH AS THE INFLUENCE OF THE AFOREMENTIONED RIDGE SETTLES
IN.

OVER NIGHT TEMPS WILL GENERALLY BE MILD WITH LOWER 60S NW TO LOWER
70S SE. NEAR SEASONAL NORMS FOR TOMORROW/S DAYTIME HIGHS...WITH UPPER
80S TO LOWER 90S ANTICIPATED.

&&

.LONG TERM...
UPPER RIDGE EXPECTED TO STRENGTHEN EARLY IN THE WEEK OVER THE
CENTRAL ROCKIES WITH INCREASING INFLUENCE OVER TEXAS SOUTH PLAINS
REGION AND WEAKENING UPPER TROUGH. MOISTURE PLUME WILL FURTHER
THIN AND SHIFT SOUTH ALLOWING ADDITIONAL TAPERING OF SHOWER
CHANCES LATE SUNDAY AND EARLY MONDAY. A DISTURBANCE BREAKING OFF
OF THE MIDWEST TROUGH AND TAKING A DIVE TO THE SOUTHWEST WILL
ALMOST CERTAINLY LEAD TO INCREASING MOISTURE SOMEWHERE IN THE
H850-H700 MB LAYER TUESDAY NIGHT AND WEDNESDAY...BUT SOME DOUBT YET
THAT IT WILL BE SUFFICIENTLY POTENT TO ALLOW WEAKENING OF THE MID
LEVEL CAP AT THAT TIME. ALSO...DOUBT ON THE PATH THIS BREAK-OFF
DISTURBANCE WILL TAKE. IF IT WERE TO LEAD TO SHOWERS ANYWHERE...IT
WOULD SEEM MOST POSSIBLE NEAR THE ROLLING PLAINS...FURTHEST FROM
THE H500 RIDGE CENTER OVER THE CENTRAL ROCKIES. WE HAVE INCREASED
THE SILENT CHANCES FOR SHOWERS THIS AREA BUT STILL RELUCTANT TO
ADD ANY MENTIONABLE SHOWERS JUST YET.

BEYOND MID-WEEK...IT APPEARS OUR AREA WILL BE MOSTLY DOMINATED BY
SUBSIDENCE TO THE SOUTH AND EAST OF THE UPPER LEVEL RIDGE AXIS
AND TO THE WEST OF THE TROPICAL SYSTEM PULLING NORTH THROUGH THE
MISSISSIPPI VALLEY OR SOUTHEAST. WE MAY BEGIN TO SEE SOME SPILL-
OVER OF MID LEVEL MONSOON MOISTURE FROM THE SOUTHWEST AGAIN BY
NEXT WEEKEND OR JUST AFTER NEXT WEEKEND...TOO DISTANT TO CONSIDER
ANY REAL SHOWER OPPORTUNITIES FOR OUR WEST OR NORTHWESTERN ZONES
AT THIS TIME.

HIGH TEMPERATURES SHOULD MODERATE SLIGHTLY MID-WEEK WITH SOME
INCREASE IN MOISTURE...THEN RISE SLOWLY FOR THE END OF THE WEEK
INTO THE WEEKEND. LOW TEMPERATURES APPEAR SEASONABLY COOL OWING TO
LIGHT WINDS AND A RELATIVELY DRY LOWER ATMOSPHERE. RMCQUEEN
