AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LUBBOCK TX
259 PM CDT WED MAY 29 2013

.SHORT TERM...
THE DRYLINE WAS LOCATED ON A LINE FROM ABOUT TURKEY TO LAKE ALAN
HENRY AT 230 PM. TO THE WEST...DEEP MIXING WAS MAKING FOR
TEMPERATURES IN THE UPPER 80S TO NEAR 90 WITH DEWPOINTS IN THE
20S-40S. SURFACE CONVERGENCE AND UPPER FORCING FROM A SHORTWAVE
TROUGH HAD PRODUCED AN AREA OF DEVELOPING CUMULUS AND WEAK RADAR
RETURNS IMMEDIATELY WEST OF THE DRYLINE WHICH WILL EVENTUALLY CATCH
UP TO THE DEEPER MOISTURE IN PLACE OUT EAST...AND LIKELY SPARK
LARGER SCALE CONVECTIVE INITIATION ACROSS THE FAR SOUTHEAST
PANHANDLE AND ROLLING PLAINS. LARGE HAIL TO BASEBALL SIZE...WIND
GUSTS OF 60-70 MPH...AND ISOLATED TORNADOES WILL BE THE MAIN THREATS
FROM THIS ACTIVITY.

THE LOW LEVEL JET WILL KICK IN THIS EVENING AND ENHANCE LOW LEVEL
WIND SHEAR ACROSS THE ABOVE MENTIONED HIGHLIGHTED AREAS...PRODUCING
AN INCREASED TORNADO THREAT BEFORE STORM ROOTS BECOME ELEVATED
FOLLOWING BOUNDARY LAYER COOLING. HAIL WILL BECOME THE PRIMARY
THREAT AS STORM BASES INCREASE IN HEIGHT AND MAINTAIN STEEP LAPSE
RATES ALOFT. STORMS WILL TAPER OFF BY AROUND MIDNIGHT AS FORCING AND
INSTABILITY WANE.

DRY AIR WILL FILTER IN ACROSS THE ENTIRE AREA THURSDAY AS WEST TO
NORTHWEST FLOW ALOFT DEVELOPS A LEE TROUGH THAT WILL PULL THE
DRYLINE EAST OF THE ROLLING PLAINS. HOT AND DRY CONDITIONS WILL
PROMOTE ELEVATED TO BRIEFLY CRITICAL FIRE WEATHER DANGER FOR MOST IF
NOT ALL OF THE EXTREME SOUTHERN PANHANDLE...SOUTH PLAINS...AND
ROLLING PLAINS. TEMPERATURES WILL CLIMB INTO THE LOW TO MID 90S
AREAWIDE UNDERNEATH MOSTLY SUNNY SKIES.

&&

.LONG TERM...
THE SOUTHERN PERIPHERY OF THE BROAD NEGATIVELY TILTED TROUGH THAT
WILL BRING US THE POTENTIAL FOR SEVERE STORMS THIS AFTN AND
EVENING...WILL BE WELL NE OF THE SOUTHERN PLAINS BY TOMORROW NIGHT.
HOWEVER...THE CENTER OF THE SAID TROUGH WILL REMAIN BACK ACROSS THE
HIGH PLAINS...WHICH MAY BE OF IMPORTANCE THIS WEEKEND. WILL GET TO
THAT LATER. TEMPS ON FRIDAY WILL BE THE WARMEST OF THE WEEK WITH
PROJECTED HIGHS IN THE UPPER 90S TO AROUND TRIPLE DIGIT READINGS.
THIS IS COURTESY OF NEAR ZONAL FLOW ALOFT PROMOTING INCREASING
HEIGHT FIELDS IN ADDITION TO 850 MB TEMPS WARMING TO AOA 30 DEGREES
CELSIUS. THE DRYLINE IS ANTICIPATED TO BE ACROSS THE FAR ROLLING
PLAINS HENCE...RELATIVELY DRY AIR WILL ENVELOP THE CWA /DEWPOINTS IN
THE 20-40 DEGREE RANGE/. WITH ABOVE NORM TEMPS COMBINED WITH RHS
DIPPING TO 10-15...AND SLIGHTLY BREEZY WSW WINDS WILL CREATE
ELEVATED TO CRITICAL FIRE WEATHER CONDITIONS PARTICULARLY ON THE
CAPROCK. REFER TO THE FIRE WEATHER DISCUSSION FOR ADDITIONAL
INFORMATION. THESE WARM CONDITIONS WILL NOT LAST LONG AS THE
AFOREMENTIONED UA DISTURBANCE NEAR THE HIGH PLAINS SENDS DOWN A
BREEZY FROPA LATE FRIDAY NIGHT/EARLY SATURDAY MORNING...THUS COOLING
TEMPS BACK INTO THE 80S. MODELS HINT AT LOW LEVEL MOISTURE
INCREASING A BIT BEHIND THE FRONT /DEWPOINTS IN THE 40-60 DEGREE
RANGE/. IT IS EXPECTED TO STALL OUT ACROSS THE PERMIAN BASIN AND BIG
COUNTRY AREAS SAT EVENING WHERE THE BEST PRECIP AND MOISTURE AXIS
WILL LIKELY RESIDE. WILL HOLD ON TO SLIGHT CHANCE POPS ACROSS THE
FAR SRN ZONES SAT EVENING-SUN AFTN...GIVEN ITS NEAREST TO THE FROPA
AND THEREFORE SOME PRECIP COULD NEAR THE SAID AREA.

EARLY NEXT WEEK...UA RIDGING WILL DOMINATE THE CENTRAL CONUS WITH
THE CENTER NOTED FROM NE OLD MEXICO TO ACROSS CENTRAL TEXAS. THIS
UPTICK IN HEIGHT FIELDS WILL ALLOW TEMPS TO WARM FROM THE 80S OVER
THE WEEKEND BACK INTO THE UPPER 90S BY MID-WEEK. THE DRYLINE WILL
RETREAT TO ERN NEW MEXICO LATE SUNDAY NIGHT...GIVEN A 20-30 KT LLJ
FILTERING IN A BIT OF LOW LEVEL MOISTURE. CONCURRENTLY...AN EMBEDDED
IMPULSE ROUNDING THE CENTER OF THE SAID RIDGE IS SHOWING TO BE THAT
SYNOPTIC SPARK FOR CI ALONG THE DRYLINE. THE IMPULSE IS AND PRECIP
IS SHOWN TO MOVE ACROSS THE SOUTHERN PLAINS EARLY MONDAY
MORNING...AS THE MEAN FLOW IS OUT OF THE WEST. THE DRYLINE WILL
SETTLE ON THE CAPROCK BY MID-WEEK...WITH ADDITIONAL QPF SIGNALS
BEING DISPLAYED OFF THE CAPROCK. CONFIDENCE OF PRECIP IS NOT HIGH
ATTM...SINCE THE UA RIDGE /AND ACCOMPANIED SUBSIDENCE/ IS RATHER
STRONG SO NOT SURE IF THE CAP WILL INDEED WEAKEN/BREAK. AS A
RESULT...8-10 PERCENT POPS APPEARS SUFFICIENT FOR NOW AND WILL AWAIT
LATER MODEL RUNS TO SEE IF MENTIONABLE POPS IS INDEED WARRANTED.

&&

.FIRE WEATHER...
ELEVATED TO BRIEFLY CRITICAL CONDITIONS WILL OCCUR THURSDAY AS
RELATIVE HUMIDITIES FALL INTO THE SINGLE DIGITS ON THE CAPROCK AND
LOW TO MID TEENS EAST OF THE ESCARPMENT. WINDS WILL BE HIGHEST
ACROSS WESTERN TO CENTRAL PORTIONS OF THE FAR SOUTHERN PANHANDLE AND
NORTHERN TO CENTRAL SECTIONS OF THE SOUTH PLAINS AT 15 TO 20 MPH.
THESE AREAS WILL LIKELY NEED A RANGELAND FIRE DANGER STATEMENT AS A
LACK OF FUELS SHOULD PRECLUDE THE NEED FOR A RED FLAG WARNING.

ELEVATED TO CRITICAL FIRE WEATHER CONDITIONS MAY ALSO DEVELOP ON THE
CAPROCK FRIDAY AFTN AS TEMPS WARM 10-12 DEGREES ABOVE
NORM...RELATIVE HUMIDITIES DROP INTO THE 8-10 PERCENT RANGE AND
20-FOOT WSW WINDS INCREASE TO AROUND 15 MPH. THERE IS A MENTION OF
THIS POTENTIAL IN THE HAZARDOUS WEATHER OUTLOOK ATTM...HOWEVER
ADDITIONAL HIGHLIGHTS MAY BE WARRANTED.
