AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LUBBOCK TX
1139 PM CDT TUE MAY 6 2014

.AVIATION...
WINDS TO BECOME GUSTY AGAIN DURING THE DAY WEDNESDAY. DRYLINE TO
SHIFT TO A POSITION NEAR A KLTS TO KABI LINE DURING THE AFTN THEN
RETREAT WWD BY EARLY EVENING. A STRONG UPPER DISTURBANCE WILL
INTERACT WITH THE RETREATING LOW LEVEL MOISTURE TO PRODUCE
SCATTERED TSRA WEDNESDAY EVENING...LIKELY EAST OF KLBB BUT WITH AT
LEAST A 30 PCT CHANCE AT KCDS.

&&

.PREV DISCUSSION... /ISSUED 616 PM CDT TUE MAY 6 2014/

AVIATION...
VFR CONDITIONS EXPECTED THROUGH THE TAF PERIOD. GUSTY SOUTH TO SW
TO PERSIST DURING THE DAYLIGHT HOURS THE REMAINDER OF TODAY AND
AGAIN WEDNESDAY AS LOW PRESSURE REMAINS ACROSS THE SRN AND CNTL
HIGH PLAINS.

PREV DISCUSSION... /ISSUED 356 PM CDT TUE MAY 6 2014/

SHORT TERM...
WATER VAPOR IMAGERY THIS AFTERNOON REVEALS A LARGE MID-LVL TROUGH
ACROSS THE GREAT BASIN...AND A SMALLER SHORTWAVE OVER NW MX AND SRN
NM....MOVING NEWD. DESPITE THE PRESENCE OF THIS FIRST WAVE...THE
DEARTH OF LOW-LVL MOISTURE SHOULD KEEP ANY T-STORM DEVELOPMENT TO
THE EAST OF OUR AREA THIS EVENING. HOWEVER...STORM CHANCES SHOULD
IMPROVE ON WED AS THE MAIN UPPER SYSTEM EDGES CLOSER AND BEGINS TO
DRAW MOISTURE FARTHER TO THE NWWD. MOISTURE WILL ONLY MAKE A LIMITED
MOVE TONIGHT THOUGH AS LOW-LVL FLOW REMAINS VEERED...50F DEWPOINTS
MAY SNEAK INTO THE SE SPLNS INTO THE CENTRAL ROLLING PLAINS.
CONTRARY TO THE TYPICAL DIURNAL TREND...THE DRYLINE IS EXPECTED TO
STAY FAIRLY STATIONARY THROUGH MIDDAY OR SO AND THEN BEGIN TO
RETREAT IN THE AFTERNOON AS LOW-LVL WINDS BACK IN RESPONSE TO THE
APPROACHING TROUGH. DUE TO THIS SOMEWHAT ATYPICAL EVOLUTION...WE
HAVE LOW CONFIDENCE IN THE EXACT LOCATION OF THE DRYLINE AROUND PEAK
HEATING...BUT THE MOST LIKELY SCENARIO SEEMS TO BE POINT TO A
POSITION JUST TO THE EAST OF THE CAPROCK ESCARPMENT. ALSO UNCERTAIN IS
THE POTENTIAL FOR T-STORMS TO THE EAST OF THE DRYLINE PRIOR TO THE
ARRIVAL OF THE BULK OF THE LIFT ASSOCIATED WITH THE UPPER TOUGH IN
THE EVENING. FCST SNDGS IN THE ERN ROLLING PLAINS SUGGEST ML CAPES
AROUND 1 TO 1.5K J/KG WITH LITTLE CINH AND MORE THAN ADEQUATE DEEP
LAYER SHEAR. HOWEVER...LOW-LVL CONVERGENCE AND UPPER-LVL SUPPORT MAY
BE LACKING. WE HAVE ADDED A SLGT CHC MENTION TO THE FCST FOR OUR ERN
ZONES IN THE AFTERNOON. ANY STORMS THAT DEVELOP WILL BE HIGH-BASED
INITIALLY AND HAVE THE POTENTIAL FOR PRODUCING LARGE HAIL AND
DAMAGING WIND GUSTS. HIGH TEMPERATURES TOMORROW WILL COOL SOMEWHAT
WILL FALLING HEIGHTS. WE EXPECT MIDDLE 80S IN THE FAR SW TX
PANHANDLE TO MIDDLE 90S IN THE SRN ROLLING PLAINS.

LONG TERM...
FOLLOWING A PROGRESSIVE UPPER TROUGH AND ASSOCIATED ACTIVE DRYLINE
LATE WEDNESDAY...THE FLOW WILL ASSUME A MORE ZONAL AND LESS
AMPLIFIED STATE AS WE MOVE INTO THE WEEKEND. OTHER THAN CHEATING
THE DRYLINE FARTHER WEST TOMORROW NIGHT MORE IN LINE WITH THE GFS
AND ECMWF...NO NOTABLE CHANGES WERE NECESSARY TO THIS FORECAST.

UNTIL A WEAK PACIFIC FRONT CLEARS THE REGION BY DAYBREAK THU...
IT APPEARS ADDITIONAL ROUNDS OF TSTORMS ARE IN THE OFFING WED
NIGHT AS THE DRYLINE LIKELY RETREATS TO NEAR A SILVERTON TO
LUBBOCK TO BROWNFIELD LINE AHEAD OF A LEAD IMPULSE EXITING THE
BASE OF THE PRIMARY UPPER TROUGH STILL NEAR THE FOUR CORNERS BY
06Z THU. LOWER THICKNESSES BY THU UNDER CYCLONIC FLOW WOULD
NORMALLY INSPIRE MORE CHANCES FOR PRECIP...BUT LL MOISTURE WILL
BE SCOURED EAST WITH NO APPRECIABLE MID-LEVEL MOISTURE AVAILABLE.
PASSAGE OF THE PRIMARY..ALBEIT WEAKENING...TROUGH BY EARLY FRIDAY
SHOULD DRAG A WEAK COLD FRONT SOUTHWARD BEFORE WASHING OUT
THEREAFTER IN DRIER SWLY FLOW.

A MORE POTENT COLD FRONT MAY BE LOOMING AS SOON AS SUNDAY IF THE
GFS IS CORRECT...OR MONDAY ACCORDING TO THE ECM AND CMC. THESE
DIFFERING CAMPS ARE SPLIT WITH THE DEGREE AND TIMING OF TROUGH
ENERGY ROTATING OUT OF THE GULF OF ALASKA BY THIS WEEKEND...SO
CONFIDENCE TO ADJUST GRIDS TOWARD THE NON-GFS MODELS IS VERY
LIMITED. KEPT THE IDEA OF A STALLING FRONT ACROSS WEST TX WITH
INCREASINGLY MOIST EASTERLY LL FLOW THROUGH THE MIDDLE OF NEXT
WEEK...BUT WILL KEEP POPS BELOW MENTION AS THE FLOW REGIME IS
HIGHLY UNCERTAIN. A NWLY FLOW PER THE GFS WOULD BE FAVORABLE IN
THIS SETUP...HOWEVER THE ECMWF/S DEEP AND DRY SWLY FLOW COULD
EASILY PUSH PRECIP WELL EAST OF THE REGION. MAX TEMPS THROUGH
THE PERIOD WILL UNDERGO A SLOW COOLING CLOSER TO CLIMO.

FIRE WEATHER...
HOT TEMPS AND DRY AIR WERE COMBINING TO REDUCE RH VALUES BELOW 10
PERCENT AREA-WIDE THIS AFTERNOON. WIND SPEEDS WERE MAINLY IN THE 20
TO 30 PERCENT RANGE...JUST HIGH ENOUGH TO SUPPORT WIDESPREAD RED
FLAG CONDITIONS. THESE CONDITIONS WILL IMPROVE AS WIND SPEEDS
DECREASE THIS EVENING. A RED FLAG WARNING REMAINS IN EFFECT UNTIL 9
PM CDT. TONIGHT...LOW LEVEL MOISTURE WILL RETURN TO SRN AND ERN
AREAS...WHILE MOISTURE RECOVERY ACROSS NRN AND WRN AREA WILL BE
POOR. FOR WEDNESDAY...WE HAVE LOW CONFIDENCE IN THE POSITION OF THE
DRYLINE BY AFTERNOON...BUT IT WILL LIKELY RUN FROM NEAR CHILDRESS
COUNTY IN THE NORTH TO NEAR GARZA COUNTY IN THE SOUTH. WEST OF THE
DRYLINE...DESPITE COOLER TEMPS...CRITICAL CONDITIONS ARE LIKELY DUE
TO GUSTY SW WINDS AND RH VALUES IN THE 5 TO 15 PERCENT RANGE. A FIRE
WEATHER WATCH REMAINS IN EFFECT FOR THE ENTIRE AREA ON WEDNESDAY AS
THE EASTERN ZONES COULD SEE RED FLAG CONDITIONS IF THE DRYLINE
MOVES FARTHER EAST THAN EXPECTED.
