.SHORT TERM...

FORECAST CHALLENGES ABOUND OVER THE NEXT 24 HOURS IN A COMPLEX
NORTHWEST FLOW PATTERN ACROSS THE SOUTHERN PLAINS. CONDITIONS ARE
SETTING UP ONCE AGAIN FOR THE POTENTIAL OF ONE OR MORE MCS
(TSTORM COMPLEXES) ORGANIZING TO THE NORTHWEST OVER THE PANHANDLE
AND SOUTH PLAINS AND MOVING SOUTHEAST LATE TONIGHT INTO EARLY
THURSDAY INTO W CNTRL TX. A STRONG UPPER LEVEL SHORTWAVE
TROUGH...CURRENTLY OVER THE NORTHERN PLAINS/ROCKIES...AND
CONCOMITANT COLD FRONT ARE DROPPING SOUTH THROUGH THE PLAINS AS I
TYPE. TSTORMS ARE EXPTD TO DVLP ALONG AND AHEAD OF THIS STRONGER
FRONT OVER THE CENTRAL/SOUTHERN HI PLAINS THIS AFTERNOON AND THEN
AFFECT OUR AREA LATE TONIGHT INTO EARLY THUR. THERE ARE STILL
UNCERTAINTIES REGARDING THE TIMING AND TRACK OF ANY POTENTIAL
MCS...AND THUS I PREFER TO KEEP POPS BELOW LIKELY UNTIL THE
EVOLUTION OF SUCH A SYSTEM IS BETTER KNOWN. THE FRONT WILL DROP
DOWN INTO W CNTRL TX DURING THE DAY ON THUR AS SURFACE
ANTICYCLOGENESIS OCCURS OVER THE CENTRAL PLAINS. AFTER THE
MORNING CONVECTIVE DEBRIS CLEARS...AFTERNOON HEATING ALONG AND
AHEAD OF THE BOUNDARY SHOULD PROVE BENEFICIAL FOR TSTORM DVLPMT.
DAYTIME HIGHS TOMORROW WILL VARY FROM THE MID 80S IN THE NORTH TO
THE UPPER 90S IN THE FAR SOUTH AND WILL BE DEPENDANT ON THE FRONT
AND CLOUD COVER.

LACY

.LONG TERM...
COLD FRONT WILL CONTINUE TO BE A FOCUS FOR THUNDERSTORMS
DEVELOPMENT AS IT DISSIPATES THURSDAY NIGHT AND FRIDAY. GFS IS A
LITTLE WEAKER...PUSHING IT SOUTH TO I-10...WHILE THE NAM PUSHES
IT FARTHER SOUTH TO DEL RIO THURSDAY NIGHT. WILL TREND TOWARD THE
NAM. THE NAM MODEL HAS BEEN WORKING BETTER THAN THE GFS IN
FRONTAL POSITION RECENTLY. ALSO THE GFS APPEARS TO BE SUFFERING
FROM CONVECTIVE FEEDBACK PROBLEMS THURSDAY NIGHT...FOCUSING A 4
TO 5 INCH RAINFALL EVENT IN THE CONCHO VALLEY. SO WILL GO CLOSER
TO LOWER NAM POPS FOR THURSDAY NIGHT. OTHERWISE KEPT A SLIGHT
CHANCE OF THUNDERSTORMS INTO FRIDAY NIGHT.

UPPER RIDGE BUILDS INTO THE REGION THIS WEEKEND. 12Z GFS HAS A
WEAK FRONT SATURDAY NIGHT ALONG RED RIVER/PANHANDLE AREA. THIS
COULD POSSIBLY BRING RAIN CHANCES TO THE BIG COUNTRY SATURDAY
NIGHT/SUNDAY MORNING...BUT SINCE IT IS A NEW FEATURE...WILL LEAVE
OUT FOR NOW.

UPPER RIDGING PATTERN SHOULD PREVENT MOST THUNDERSTORM DEVELOPMENT
NEXT WEEK. HOWEVER THERE IS STILL UNCERTAINTY ON RAINFALL
POTENTIAL. THE 12Z GFS RUN IS TRENDING TOWARD A WEAKER...FLATTER
RIDGE...AND EVEN TOWARD A NW FLOW PATTERN. IF THE TREND
CONTINUES...COULD SEE POPS INTRODUCED OVER THE EASTERN OR NORTHERN
BIG COUNTRY. FOR NOW... WILL KEEP FORECAST DRY.
