SHORT TERM
 
 
(TONIGHT THROUGH FRIDAY NIGHT)  
ISSUED AT 150 PM CST THU DEC 8 2022  
 
BROAD SUBTROPICAL RIDGING REMAINS IN PLACE ACROSS THE GULF OF MEXICO  
AND NORTHERN MEXICO, BUT WILL WEAKEN SOME THROUGH THE COURSE OF THE  
NEXT 36 HOURS, LEADING TO HEIGHT FALLS ACROSS SOUTH-CENTRAL TEXAS AS  
A LEAD SHORTWAVE MOVES OVER THE WESTERN CONUS. OUR WARM, HUMID  
CONDITIONS WILL CONTINUE THROUGH THE SHORT TERM, RESULTING IN CLOUDY  
OVERNIGHTS AND MORNINGS WITH PATCHY FOG AND DRIZZLE, AND PARTLY  
SUNNY AFTERNOONS. THE FOG COULD BECOME LOCALLY DENSE, BUT AT THIS  
TIME WE DON'T ANTICIPATE WIDESPREAD ENOUGH DENSE FOG TO WARRANT AN  
ADVISORY FOR FRIDAY MORNING.  
 
TEMPERATURES THIS AFTERNOON ARE MAINLY IN THE 70S. MANY LOCATIONS  
NEAR AND EAST OF I-35 SHOULD TOUCH THE LOWER 80S AT LEAST BRIEFLY,  
ESPECIALLY IN AREAS THAT SEE A BIT MORE SUNSHINE. AFTER LOWS IN THE  
60S, FRIDAY WILL AGAIN FEATURE HIGHS IN THE 70S TO PERHAPS LOWER  
80S. THEN WASH, RINSE, REPEAT OVERNIGHT WITH THE PATCHY FOG AND  
DRIZZLE DEVELOPING ONCE AGAIN MAINLY AFTER MIDNIGHT. CAN'T RULE OUT  
ONE OR TWO OF OUR CLIMATE SITES BREAKING A RECORD HIGH MINIMUM  
TEMPERATURE FOR TODAY OR TOMORROW.  
 

 
   
LONG TERM
 
 
(SATURDAY THROUGH THURSDAY)  
ISSUED AT 205 PM CST THU DEC 8 2022  
 
MUGGY AND MILD WEATHER WILL CONTINUE INTO THE WEEKEND AS SOUTHERLY  
FLOW REMAINS IN PLAY SATURDAY AFTERNOON. TEMPERATURES WILL RUN A GOOD  
10-15 DEGREES ABOVE NORMAL, WITH HIGHS RANGING FROM THE LOWER 70S TO  
THE LOWER 80S. AN INCREASE IN MID TO HIGH LEVEL CLOUDS OUT OF THE  
SOUTHWEST WILL SIGNAL THE NEXT SHOT AT RAIN/THUNDERSTORMS FOR THE  
BACK HALF OF THE WEEKEND. A COMPACT SHORTWAVE WILL SLIDE EASTWARD ON  
SATURDAY AFTERNOON, LIFTING FROM SOUTHERN ARIZONA TO THE TEXAS  
PANHANDLE BY LATE EVENING. A COLD FRONT WILL GET SENT IN OUR  
DIRECTION LATE SATURDAY NIGHT INTO EARLY SUNDAY MORNING, WITH THE  
THREAT FOR SHOWERS AND THUNDERSTORMS PRECEDING ITS PASSAGE. AT THIS  
TIME, THERE APPEARS TO BE ENOUGH MUCAPE TO PRODUCE PERHAPS A COUPLE  
OF ISOLATED THUNDERSTORMS, BUT THE THREAT FOR SEVERE WEATHER LOOKS  
FAIRLY LOW AT THIS DISTANCE. STREAMER SHOWERS/ISOLATED STORMS LOOK  
LIKE A DECENT BET SUNDAY MORNING BEFORE DAWN AND MAY CONTINUE THROUGH  
EARLY AFTERNOON BEFORE TAPERING OFF BY EARLY AFTERNOON. AS FAR AS QPF  
GOES, COORDINATED WITH WPC IN BUMPING UP QPF ACROSS THE EASTERN HALF  
OF THE AREA AS THE NBM IS A BIT DRIER THAN PRETTY MUCH EVERY OTHER  
MODEL. SOME LUCKY SPOTS MAY PICK UP A QUICK 1/4 TO 1/2 INCH, BUT MOST  
WILL SEE BETWEEN .1 AND .2" SUNDAY MORNING ALONG AND EAST OF THE  
I-35 CORRIDOR. AS A RESULT OF THE WEAK COLD FRONT AND INCREASED  
CLOUD COVER, SUNDAY WILL PROBABLY BE A TAD COOLER, BUT STILL ABOUT  
5-10 DEGREES ABOVE MID- DECEMBER NORMALS.  
 
MONDAY WILL FEATURE WARM AND MUGGY CONDITIONS ONCE AGAIN WITH HIGHS  
TOPPING OUT IN THE MID TO UPPER 70S. FACTORING IN SURFACE DEWPOINTS  
IN THE 60S AND IT WON'T FEEL MUCH LIKE DECEMBER OUT THERE. MONDAY  
WILL PROBABLY BE OUR LAST RELATIVELY QUIET WEATHER DAY FOR THE  
REMAINDER OF THE UPCOMING WEEK AS A POWERFUL 500MB TROUGH DEEPENS  
OVER THE FOUR CORNERS LATE MONDAY INTO EARLY TUESDAY. SOME ISOLATED  
SHOWERS ARE POSSIBLE OVER THE EXTREME EASTERN PORTIONS OF THE AREA  
(E OF HIGHWAY 77), BUT ANY ACCUMULATIONS WILL BE FAIRLY LIGHT FOR  
MONDAY. TUESDAY WILL SEE THE POSSIBILITY OF SEVERE WEATHER TO THE  
NORTH OF THE EWX CWA, AS MEDIUM-RANGE GUIDANCE HAS BEEN IN REMARKABLY  
GOOD AGREEMENT ON THE EVOLUTION OF THE OVERALL SYNOPTIC PATTERN  
THROUGH THE MIDDLE OF NEXT WEEK. AS OF RIGHT NOW, SPC HAS A DAY 5  
OUTLOOK CENTERED OVER THE ARKLATEX, WHICH INCLUDES THE DFW METRO, BUT  
REMAINS NORTH OF THE AUSTIN METRO AT THIS TIME. IF THINGS WERE TO  
CHANGE A BIT OVER THE NEXT COUPLE MODEL RUNS, STORMS COULD TREND  
FURTHER SOUTH AND ALONG WITH IT, A CONDITIONAL SEVERE THREAT,  
HOWEVER, THAT APPEARS SOMEWHAT UNLIKELY AT THIS TIME. WE MAY STILL  
MANAGE TO SQUEEZE OUT A FEW 10THS OF AN INCH EAST OF THE I-35  
CORRIDOR, BUT THIS DOES NOT APPEAR TO BE A SIGNIFICANT RAIN MAKER  
FOR OUR NECK OF THE WOODS.  
 
A COLD FRONT WILL SWEEP THROUGH EARLY TUESDAY AFTERNOON, BRINGING  
BREEZY CONDITIONS TO SOUTH-CENTRAL TEXAS AND PERHAPS SOME ELEVATED  
FIRE WEATHER CONDITIONS TO THE RIO GRANDE PLAINS. MUCH COOLER AIR  
SHOULD FILTER IN BEHIND THE FRONT, BRINGING AN END TO THAT NASTY AIR  
WE'VE HAD TO PUT UP WITH THE PAST WEEK AND A HALF. TEMPERATURES WILL  
RETURN TO MORE SEASONABLE LEVELS, IN THE 50S AND 60S BY THE END OF  
THE WEEK.  
 

 
   
AVIATION
 
 
(00Z TAFS)  
ISSUED AT 541 PM CST THU DEC 8 2022  
 
A HIGH MOISTURE CONTENT IN THE LOW LEVELS AND A BROAD AND FLAT  
RIDGING PATTERN ALOFT WILL CONTINUE TO ENABLE A NEAR PERSISTENCE  
PATTERN IN THE TERMINAL FORECASTS. WIND TRENDS SHOULD BE MOSTLY  
PERSISTENCE, BUT AN APPROACHING TROUGH FROM THE WEST WILL PICK UP  
SPEEDS IN THE LATER PERIODS. ALL SKIES AT THE FOUR TAF SITES SHOULD  
VFR FOR THE FIRST FEW HOURS. SOME MVFR CIGS COULD DEVELOP AS EARLY AS  
03Z AROUND SAT/SSF AND PROBABLY CLOSER TO MIDNIGHT AT DRT/AUS. THIS  
IS A SLIGHT HEDGE TOWARD PERSISTENCE OVER THE MOS GUIDANCES WHICH ARE  
ROUGHLY A COUPLE HOURS SLOWER. NEVERTHELESS THE BROADER TREND IS FOR  
SLIGHTLY LESS VSBY RESTRICTIONS AS THE DEEP WARM AND MOIST LAYER IS  
ACCOMPANIED BY A GRADUAL INCREASE IN LOW LEVEL WIND SPEEDS. LOWEST  
CIGS AND VSBYS NEAR DAYBREAK ARE FORECAST OVER THE HIGHER INLAND  
TERRAIN AND DRT.
