AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LUBBOCK TX
626 AM CDT THU MAR 27 2014

.AVIATION...
PRIMARY CONCERN TODAY WILL BE WINDS. THERE EXIST SOME LOW STRATUS
LINGERING ABOUT BOTH TERMINALS THOUGH THOSE CONCERNS SHOULD NO
LONGER BE A FACTOR AFTER ABOUT 1230Z WHEN THE DRYLINE PUSHES
THROUGH BOTH TERMINALS. WHILE WINDS ARE EXPECTED TO BE IN THE
25 KT RANGE AT KLBB...DUST WAS LOFTED QUITE READILY LAST EVENING
WITH LESSER SPEEDS AND THIS IS REFLECTED IN THE TAF AS THE WINDS
PICK UP LATER THIS MORNING. THAT SAID...DUST VISIBILITY REDUCTIONS
ARE OFTEN QUITE TRICKY TO FCST.

.PREV DISCUSSION... /ISSUED 258 AM CDT THU MAR 27 2014/

SHORT TERM...
HAT APPEARED YESTERDAY AS A FAIRLY EASY DECISION FOR FIRE WEATHER
AND WIND SPEEDS HAS BECOME MORE COMPLEX THIS MORNING.  ZONAL FLOW
EXISTS OVER MUCH OF THE CONUS THIS MORNING WITH A MID LEVEL TROUGH
APPROACHING WEST TEXAS FROM THE WEST.  OVERALL...THE TIMING OF THIS
SYSTEM IS A BIT FASTER THAN PREVIOUSLY ANTICIPATED.  THIS WOULD
SUGGEST THAT THE OVERSPREADING OF HIGHEST UL WIND WOULD OCCUR BEFORE
BEST DIURNALLY DRIVEN MIXING OCCURS THIS AFTERNOON.  EMBEDDED MID
LEVEL SPEED MAX INDICATED ON THE NAM BUT MISSED ON OBJECTIVE RAOBS
ANALYSIS IS EVIDENT ON WV IMAGERY ACROSS ERN AZ AND WRN NM.  GIVEN
PERSISTENCE...THIS FEATURE SHOULD BE ABEAM OUR CWFA BY 12Z AND
EXITING ACROSS OK BY 18Z. HAD THIS MAX DELAYED BY 6 HOURS...WE
WOULD LIKELY BE DEALING WITH A HIGH WIND WARNING DAY. THE DRYLINE
LOOK TO HAVE MADE IT ABOUT AS FAR WEST AS IT IS GOING TO GET AS OF
07Z AND PRESSURE FALLS ARE NOTED TO THE EAST OF THE BOUNDARY...
THUS...IT SHOULD BE ON THE MOVE SOON. LOW STRATUS HAS MANAGED TO
WORK ITS WAY INTO THE CENTRAL SOUTH PLAINS BUT THIS SHOULD EASILY
SCOUR QUICKLY WITH THE EASTWARD ADVANCING DRYLINE. HIGH LEVEL
CLOUDINESS ASSOCIATED WITH THE AFOREMENTIONED JET MAX SHOULD HELP
LIMIT MIXING BEFORE 18Z WITH A CLEARING TREND UNTIL LATE THIS
AFTERNOON.

GIVEN ALL THIS...WILL GO AHEAD AND UPGRADE ENTIRE CWA TO RED FLAG
WARNING FOR LATE THIS MORNING UNTIL 00Z AS WINDS SHOULD BE ON THEIR
WAY DOWN.  WITH REGARD TO WIND ADVISORY POTENTIAL...THAT IS A BIT
MORE COMPLEX.  HEREFORD/HOBBS SODAR INDICATES 50KT WINDS RIGHT OFF
THE DECK THOUGH THAT IS MORE ASSOCIATED WITH THE LLJ INVOF THE
DRYLINE AND SUSPECT THAT WE WILL SEE THAT EASE THROUGH SUNRISE.  AS
THE SUN STARTS TO MIX THE LOWER LEVELS...WILL CLOSELY MONITOR
ISOTACH TRENDS.  THE UPPER LEVEL CLOUDS OVER NM WILL INHIBIT MIXING
TO SOME EXTENT DURING THE PERIOD OF PEAK WINDS ALOFT.
HOWEVER...THESE SHOULD CLEAR THE AREA AROUND 18Z.  WHILE THE WIND
MAX EXITS...MORE EFFICIENT THERMAL PROFILES SHOULD ENABLE THE SPEEDS
TO STAY UP MUCH OF THE AFTERNOON.  CONFIDENCE IN ADVISORY CRITERIA
IS NOT SUFFICIENT AS OF 08Z...BUT WE SHALL SEE.

AFTER DARK...WINDS SHOULD DIMINISH QUICKLY LEADING TO A PLEASANT AND
SEASONABLY COOL NIGHT.

LONG TERM...
TODAY/S WINDY...DUSTY AND CRITICAL FIRE WEATHER HIGHLIGHTS...WILL BE
FOLLOWED BY A MUCH QUIETER DAY TOMORROW...THOUGH ANOTHER /WEAKER/ UA
DISTURBANCE PROGRESSING EWRD ACROSS THE CENTRAL PLAINS WILL SEND
DOWN A BACKDOOR COLD FRONT TO ACROSS THE ROLLING PLAINS. THE ANEMIC
FRONT IS ANTICIPATED TO BECOME QUASI-STATIONARY ACROSS THE ERN ZONES
DURING THE MORNING HOURS...BEFORE FINALLY MAKING ITS WAY TO THE
REMAINDER OF CWA BY THE OVERNIGHT HOURS. THUS...ONLY A SLIGHT COOL
DOWN IS EXPECTED WITH HIGHS IN THE 60S AND 70S. OVER THE
WEEKEND...UL HEIGHT FIELDS WILL INCREASE COURTESY OF THE PASSAGE OF
A LOW AMPLITUDE UA RIDGE. THIS BEING COUPLED WITH THE RETURN OF
BREEZY /15-20 MPH/ SFC SRLY FLOW WILL LEAD TO HIGHS WARMING NICELY
INTO THE 70S AND 80S...WITH SUNDAY BEING THE WARMEST AND BREEZIEST
OF THE TWO DAYS.

AN UA DISTURBANCE EJECTING OUT OF THE CENTRAL ROCKIES TO ACROSS THE
CENTRAL PLAINS MONDAY WILL CAUSE THE IMPINGEMENT OF ANOTHER DRY AND
WEAK COLD FRONT BY THE MORNING HOURS. HENCE...TEMPS WILL ONLY BE
SLIGHTLY TEMPERED /70S/. THEREAFTER...THINGS COULD BECOME INTERESTING
AS ANOTHER BROAD UA LOW NEARS THE CENTRAL ROCKIES TUESDAY...LEADING
TO FLOW ALOFT TO BACK TO A SWRLY FLOW. CONCURRENTLY...THE SOUTHERN
PLAINS AND ROLLING PLAINS WILL BECOME ENCOMPASSED BY AN UPSLOPE SFC
REGIME WHICH WILL ALLOW THE GRADUAL RETURN OF LOW LEVEL MOISTURE
/PROGGED PWATS OF 0.50-0.80 INCHES BY TUESDAY MORNING/. AS THE
AFOREMENTIONED UA DISTURBANCE NEARS THE CENTRAL PLAINS...ITS PACIFIC
FRONT WILL PUSH INTO THE WRN ZONES AND THE AN OBVIOUS DRYLINE WILL
COMMENCE TO TAKE SHAPE /SHARPENING ACROSS THE CAPROCK BY THE AFTN/.
MODELS CONTINUE TO HINT AT DRYLINE CONVECTION BY THE AFTN OFF THE
CAPROCK...SINCE PWATS ARE ANTICIPATED TO INCREASE TO AOA 1.00 INCH
THERE. HAVE INCREASED POPS TO JUST BELOW MENTIONABLE LEVELS OFF THE
CAPROCK TUESDAY ESPECIALLY SINCE THIS IS DAY 6 THAT WE ARE TALKING
ABOUT...THOUGH IF MODELS CONTINUE TO SHOW THIS TREND...CATEGORICAL
POPS WILL BE WARRANTED. AS THE UA DISTURBANCE PROGRESSES EWRD...SO
WILL ITS PACIFIC FRONT/DRYLINE...WITH IT BEING LOCATED EAST OF THE
CWA BY WEDNESDAY EVENING...MAKING WAY FOR ANOTHER COLD FRONT THAT
NIGHT. AS A RESULT...EXPECT COOLER CONDITIONS TOWARDS THE END OF THE
WEEK /60S/.

FIRE WEATHER...
TIMING OF UPPER LEVEL DISTURBANCE IS ABOUT 6 HOURS TOO EARLY AS
COMPARED TO THE SOUTH PLAINS OUTBREAK PATTERN...THOUGH WE DO EXPECT
TO CLICK OFF A FAIR NUMBER OF RED FLAG MINUTES FROM A METEOROLOGICAL
STANDPOINT.  DESPITE YESTERDAY/S RAINS...FUELS ARE QUITE VOLATILE
AND NEAR THE 90TH PERCENTILE ON ERC/S.  WITH 20 FT WINDS IN THE 20-30
MPH RANGE THIS AFTERNOON AND RH NEAR 10 PCT...CONCERNS CERTAINLY
JUSTIFY RED FLAG WARNING BASED ON AVAILABLE DATA.
