AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE LUBBOCK TX
1206 AM CDT MON JUN 23 2014

.AVIATION...
CONFIDENCE IS HIGH THAT SEVERE THUNDERSTORMS WILL IMPACT KCDS.
THUNDERSTORMS WILL ALSO IMPACT KLBB BUT THE STRENGTH REMAINS
UNCERTAIN ON WHETHER IT WILL BE SEVERE OR NOT FURTHER SOUTH. HAVE
UPDATED TAFS TO INCLUDE TEMPO GROUPS FOR STORMS WITH SOME
UNCERTAINTY IN THE TIMING. STORMS SHOULD BE THROUGH THE TERMINALS
BEFORE SUNRISE WITH MVFR CEILINGS REMAINING IN PLACE UNTIL
AFTERNOON. MAY BE A CHANCE FOR ANOTHER ROUND OF STORMS AT KLBB
MONDAY AFTERNOON BUT CONFIDENCE IN TIMING REMAINS TOO LOW TO
INCLUDE AT THIS TIME.

JORDAN

&&

.UPDATE...
HAVE UPDATED THE GRIDS FOR THE DEVELOPING MCS WHICH WILL CROSS
OVER THE ROLLING PLAINS. GREATER UNCERTAINTY REVOLVES AROUND THE
STORMS OVER NEW MEXICO THAT ARE PUSHING EAST. OUTFLOW BOUNDARIES
ARE STARTING TO RACE OUT AHEAD OF THE MAIN CONVECTIVE CORES WHICH
WILL LIKELY CONTINUE TO LIFT PARCELS ABOVE THE COLD POOL. STORMS
HEADING TOWARDS CHILDRESS WILL HAVE A BETTER CHANCE AT REMAINING
INTACT AND PRODUCE SEVERE GUSTS AND HAIL AS IT IS PERPENDICULAR TO
THE LOW LEVEL JET AXIS. NEW MEXICO STORMS MAY STRUGGLE SOME AS IT
IS ORIENTED A BIT MORE PARALLEL TO THE LOW LEVEL JET AXIS. GRIDS
AND PRODUCTS HAVE BEEN UPDATE FOR CATEGORICAL POPS AND ADD MENTION
OF SEVERE.

.PREV DISCUSSION... /ISSUED 628 PM CDT SUN JUN 22 2014/

AVIATION...
VFR CONDITIONS IN PLACE AT BOTH KLBB AND KCDS CURRENTLY HOWEVER
EXPECT TO SEE MVFR CONDITIONS DEVELOP OVERNIGHT. CONFIDENCE IS
INCREASING THAT A COMPLEX OF THUNDERSTORMS WILL IMPACT KCDS
OVERNIGHT TONIGHT AFTER 06Z AND POSSIBLY LASTING THROUGH SUNRISE
MONDAY. KLBB SHOULD BE FAR ENOUGH WEST THAT STORMS WILL MISS THE
TERMINAL BUT THERE IS A SLIM POSSIBILITY THAT STORMS COULD DEVELOP
WEST TOWARDS THE TAFS. AMPLE LOW-LEVEL MOISTURE WILL ALSO BE IN
PLACE AND COMPUTER FORECASTS ARE SHOWING MVFR CEILINGS POSSIBLE
EARLY MONDAY MORNING THROUGH NOON AT KLBB. CONFIDENCE IS LOW
HOWEVER IN CEILING HEIGHTS AND TIMING OF ONSET AND DISSIPATION SO
WILL NEED TO EVALUATE THROUGH THE NIGHT.

JORDAN

PREV DISCUSSION... /ISSUED 338 PM CDT SUN JUN 22 2014/

SHORT TERM...
UA RIDGING ACROSS THE ERN PACIFIC HAS STRETCHED TO ACROSS THE
SOUTHERN PLAINS THIS AFTERNOON...LEADING TO INCREASING HEIGHT FIELDS
AND THUS WARMER TEMPS /80S AND 90S/...WHICH IS TYPICALLY WHAT ONE
WOULD EXPECT FOR THE START OF A WEST TEXAS SUMMER DAY /VERSUS
YESTERDAY/S COOLER AND RAINY WEATHER/. SLIGHT NW FLOW ALOFT HAS ALSO
DEVELOPED GIVEN A SLIGHT INCREASE IN THE MAGNITUDE OF THE
AFOREMENTIONED UA RIDGE. RATHER AGITATED CU FIELDS AND ISOLATED
STORMS HAVE DEVELOPED ACROSS NEW MEXICO FROM WEST OF SANTA ROSA TO
EAST OF WHITE SANDS...COINCIDING WITH THE LOCATION OF A SFC TROUGH.
MODEL SOLUTIONS HINT AT ADDITIONAL DEVELOPMENT AND WITH ADEQUATE
WRLY STEERING FLOW...STORMS COULD DRIFT TOWARDS/ACROSS THE WRN ZONES
LATER THIS EVENING /THE NAM IS MOST BULLISH IN SHOWING THIS
DEPICTION/. IF STORMS DO INDEED MAKE IT THE CWA...PROGGED SOUNDINGS
ACROSS THE WRN ZONES EXHIBITING AN INVERTED-V PROFILE...COUPLED WITH
SFC-BASED CAPE VALUES OF 1.5-2.5 KG/KG AND 0-6 KM BULK SHEAR AOA 25
KTS...SUGGESTS THE POTENTIAL FOR STRONG STORMS WITH GUSTY WINDS AND
HAIL BEING THE PRIMARY THREATS. IT IS INTERESTING TO NOTE THAT A
QUASI-STATIONARY COLD FRONT HAS IMPINGED ON THE WRN OKLAHOMA
PANHANDLE AND IS CAUSING ISOLATED STORMS TO DEVELOP.  THIS FRONT
WILL BE AN IMPORTANT MESOSCALE FEATURE TONIGHT...AND WILL BE
DISCUSSED FURTHER BELOW.

ATTENTION QUICKLY TURNS TO CONVECTION DEVELOPING ACROSS THE HIGHER
MOUNTAINOUS TERRAIN OF SE CO AND NE NM TONIGHT...AHEAD OF AN UA
SHORTWAVE THAT WILL BE TRANSLATING TO ACROSS THE CENTRAL
PLAINS/PANHANDLES. A MODERATELY STRONG AND BREEZY COLD FRONT IN
ASSOCIATION WITH THE SHORTWAVE IS ANTICIPATED TO CONTINUE ITS
SOUTHWARD PROPAGATION ACROSS THE REMAINDER OF THE PANHANDLES
TONIGHT...THUS PROVIDING THE STORM ACTIVITY WITH FRONTOGENETICAL
SUPPORT ALONG WITH THE ALREADY NEARBY UL SUPPORT FROM THE SHORTWAVE.
MODEL SOLUTIONS CONTINUE TO DEPICT THE EVOLUTION OF AN MCS THAT WITH
THE HELP OF THE SLIGHT NW FLOW ALOFT...WILL SHIFT SE TO ACROSS THE
SERN TX PANHANDLE/NORTHERN ROLLING PLAINS THROUGH LATE TONIGHT/EARLY
TOMORROW MORNING. PWATS OVER 1.00 INCH WILL BE EASILY MAINTAINED OR
PERHAPS SLIGHTLY INCREASE AS A NOCTURNAL LLJ KICKS UP INTO THE
25-30 KT RANGE TONIGHT. THIS RAISES CONCERNS FOR THIS MCS TO PROMOTE
LOCALIZED MODERATE-HEAVY RAINFALL. FURTHERMORE...EMBEDDED STRONG TO
SEVERE STORMS WILL BE A POSSIBILITY...AS MID-LEVEL CAPE AOA 2.0
KG/KJ WILL EXIST. HENCE...SEVERE WIND GUSTS /AT LEAST 58 MPH/ AND
SEVERE HAIL /AT LEAST QUARTER-SIZED/ ARE ALSO PLAUSIBLE.

TOMORROW MORNING...THE WANING MCS WILL BE EXITING EAST OF THE FA
HOWEVER...THE COLD FRONT/COLD POOL BOUNDARY WILL MOVE ACROSS THE
REGION AND BACK SFC WINDS TO THE E-NE. THIS UPSLOPE SFC REGIME WILL
CAUSE PWATS TO PERSIST ABOVE 1.00 INCH AND PERHAPS MAINTAIN LINGERING
PRECIP FOR THE AFTN. WILL NEED TO KEEP IN MIND THAT ANYTIME THERE IS
NOCTURNAL CONVECTION...IT HAS A DIRECT IMPACT ON WHAT OCCURS THE
NEXT DAY...BE IT DELAYED PRECIP DEVELOPMENT DUE TO BL STABILIZATION
AND/OR LINGERING BOUNDARIES BEING A FOCUS FOR PRECIP DEVELOPMENT.
OVERNIGHT LOWS WILL BE SIMILAR TO YESTERDAY...WITH A RANGE FROM THE
LOWER 60S ACROSS THE SW TX PANHANDLE TO THE LOWER 70S ACROSS THE LOW
ROLLING PLAINS. HIGHS TOMORROW WILL BE COOLER THAN
TODAY...ESPECIALLY SINCE BENEFICIAL RAINFALL AND PLENTIFUL CLOUDS
ARE EXPECTED /80S WITH A FEW 90S/.

LONG TERM...
UPPER LEVEL HEIGHTS SHOULD BE IN PROCESS OF FALLING AS UPPER
TROUGHING DEVELOPS OVER THE AREA MONDAY NIGHT INTO TUESDAY. MOIST
LOW LEVEL SOUTHEAST FLOW SHOULD REDEVELOP BY LATE MONDAY THOUGH
STILL SOMEWHAT UNCLEAR HOW UNSTABLE LOWER LEVELS WILL MANAGE AFTER
POSSIBLY BEING SOMEWHAT WORKED OVER EARLIER IN THE DAY. REGARDLESS...
WE EXPECT TO SEE THUNDERSTORMS DEVELOPING TO OUR WEST-NORTHWEST
LATE MONDAY AND MOVE OUR WAY INTO THE NIGHT. STILL NOT CLEAR IF
MORE OUR NORTHERN OR SOUTHERN ZONES ARE ALL THAT MUCH MORE FAVORED
THOUGH RETAINED THE SLIGHT LEAN TOWARDS SOUTHERN AREAS WHERE
REMNANTS OF FRONTAL BOUNDARY ARE MORE LIKELY TO BE. SHEAR LEVELS
AND POTENTIAL INSTABILITY BOTH CURRENTLY APPEAR MARGINAL FOR
SEVERE CONSIDERATION THOUGH CERTAINLY CANNOT RULE OUT AN ISOLATED
LOW END HIGH WIND OR SEVERE HAIL REPORT MONDAY NIGHT. ACTIVITY
WOULD BE EXPECTED TO CONTINUE INTO EASTERN AREAS OVERNIGHT PERHAPS
LEAVING LIGHTER SHOWERS BEHIND INTO EARLY TUESDAY GIVEN AMOUNT OF
UPPER TROUGH AND AS SEEING WITH VARIOUS MODEL DEPICTIONS...THOUGH
A COOLER MORE STABLE LOWER ATMOSPHERE WILL BE IN PLACE. SOLUTIONS
ALSO OFFER STILL A CHANCE FOR MORE ACTIVITY TO FORM LATE TUESDAY
INTO EARLY WEDNESDAY AS UPPER TROUGH STILL IN THE VICINITY THOUGH
CONVECTIVE SIGNALS DO NOT LOOK AS PRONOUNCED AS LATE MONDAY EVENT.
AND EVEN LATE WEDNESDAY INTO EARLY THURSDAY HEIGHTS WILL BE
REBOUNDING BUT STILL PERHAPS NOT YET CAPPED ENOUGH TO ELIMINATE
FURTHER THUNDER CHANCES...ESPECIALLY FOR OUR NORTHERN ZONES
ADJACENT TO MORE FAVORABLE PANHANDLE AREAS. AT LEAST BRIEF UPPER
RIDGING SHOULD CENTER ON LATE THURSDAY AND EARLY FRIDAY BEFORE
NEXT ROUND OF HEIGHT FALLS SPREAD DOWNSTREAM OF AN UNSEASONABLE
VIGOROUS LOOKING PACIFIC TROUGH CROSSING THE COAST. THE GFS
REMAINS UNWAVERINGLY FLAT WITH THIS SYSTEM COMPARED TO OTHER
OUTPUT...AND EVEN THOUGH THE ECMWF MAY YET BE TOO DEEP AND TROUGHY
BY THE END OF THE WEEK AND INTO THE WEEKEND...WE BELIEVE THE
PATTERN SHOULD SUPPORT REDEVELOPMENT OF AT LEAST ANOTHER WEAK
UPPER TROUGH WITH PACIFIC MOISTURE TRANSPORT AND ALSO VALID
THUNDER CHANCES. WE INTRODUCED THUNDER FROM LATE FRIDAY THROUGH
THE WEEKEND TRENDING TEMPERATURES A LITTLE BELOW MOST GUIDANCE.
