AVIATION
 
 
VFR CONDITIONS WILL PERSIST ACROSS THE AREA FOR NEXT 24 HOURS.  
MODELS ARE PICKING ON A POSSIBLE LOW STRATUS DECK FORMING OVER  
KMAF TOMORROW MORNING (13Z-16Z), BUT THERE IS TO MUCH UNCERTAINTY  
TO INCLUDED IN THIS TAF CYCLE. LIGHT WINDS REMAIN OUT OF THE S TO  
SW TONIGHT. TOMORROW AFTERNOON WINDS COULD TEMPORARILY BE GUSTY  
OUT OF THE SW TO W FOR THE WESTERN SITES.  
 

 
 
PREV DISCUSSION... /ISSUED 153 PM CST FRI FEB 26 2021/  
 
DISCUSSION...  
INCREASING SW MID-LEVEL FLOW WILL FAVOR THE DEVELOPMENT OF SURFACE  
PRESSURE FALLS ACROSS E NM/W TX PLAINS SAT AND DEEP MIXING WILL  
CONTRIBUTE TO A SUSTAINED DOWNSLOPE COMPONENT. AS SUCH A SHARP WARM-  
UP IS EXPECTED DESPITE THE PRESENCE OF HIGH CLOUDS. WINDS WILL BE ON  
THE BREEZY SIDE FOR MUCH OF THE AFTERNOON AND WILL FLIRT WITH HIGH  
WINDS IN THE FAVORED AREAS OF THE GDP MTNS. MEANWHILE A WELL DEFINED  
COLD FRONT WILL BE LURKING IN THE FAR NRN PANHANDLE SAT EVENING THEN  
ARRIVING NEAR I-20 BY 15Z SUN. CONCURRENTLY AN UPPER LOW WILL BE  
APPROACHING FROM THE W LATE SUN NIGHT/MON AM AND AS IT DOES THE LOW-  
LEVEL WINDS WILL INCREASE FROM THE E ADVECTING MSTR WWD IN 85H-7H  
LAYER. NAM12 HAS MODEST POPS, LOW-LEVEL LIFT IN THE MST LAYER DOES  
SEEM TO SUPPORT GOOD CHANCE POPS, BUT LOW QPF, DECREASING QUICKLY  
INTO MON AFTERNOON. MODELS HAVE TRENDED UP THE LOW TEMPS TOO, AT  
LEAST SLIGHTLY. WARMER TUE AND MORESO WED. TIMING/DEPTH DIFFERENCES  
ON THE PASSAGE OF THE TROF THUR WITH GFS SUGGESTING DRY WINDY  
CONDITIONS THUR PM FOLLOWED BY DRY COLD FRONT FRI.  
 
FIRE WEATHER...  
THE WARMING AND DRYING TREND THAT BEGAN TODAY WILL CONTINUE  
SATURDAY, WITH HIGH TEMPERATURES AROUND 10-15 DEGREES ABOVE NORMAL  
EXPECTED ACROSS MOST OF SOUTHEAST NEW MEXICO AND WEST TEXAS.  
CONCURRENTLY, A TIGHTENING PRESSURE GRADIENT ACROSS THE HIGHER  
TERRAIN OF SOUTHEAST NEW MEXICO AND WEST TEXAS WILL YIELD INCREASING  
WESTERLY TO SOUTHWESTERLY WINDS FROM LATE MORNING THROUGH THE  
AFTERNOON, WITH THE STRONGEST WINDS EXPECTED ACROSS THE RIDGETOPS.  
HOWEVER, A DOWNSLOPE COMPONENT IS EXPECTED, THUS THE WINDY  
CONDITIONS MAY CARRY ACROSS THE IMMEDIATELY ADJACENT PLAINS EAST OF  
THE SACRAMENTO FOOTHILLS AND THE GUADALUPE AND DELAWARE MOUNTAINS.  
THERE REMAINS A BIT OF UNCERTAINTY IN HOW STRONG THE WINDS WILL  
BECOME GIVEN AN EXPANSIVE CIRRUS DECK PROGGED TO SET UP RESIDENCE  
OVER THE AREA TONIGHT THROUGH TOMORROW, THOUGH CURRENT FORECAST 20FT  
WINDS WILL BE 30-35MPH ACROSS THE RIDGETOPS AND 20-25MPH AT LOWER  
ELEVATIONS IN THE MOUNTAINS, WITH HIGHER GUSTS EXPECTED. ACROSS THE  
PLAINS, WINDS WILL BE MORE BORDERLINE, IN THE 15-20MPH RANGE. GIVEN  
THE WARM AND WINDY CONDITIONS, RHS SATURDAY AFTERNOON WILL PLUMMET,  
WITH WIDESPREAD SINGLE DIGIT RHS ACROSS MOST OF THE REGION, SAVE FOR  
THE EASTERN PERMIAN BASIN AND STOCKTON PLATEAU.  
 
WHILE WEATHER CONDITIONS FOR CRITICAL FIRE WEATHER WILL CERTAINLY BE  
FULFILLED WHERE WINDS ARE STRONGER, THE LIMITING FACTOR REMAINS THE  
STATE OF FUELS, WITH ERCS HOVERING NEAR OR BELOW THE 70TH PERCENTILE  
ACROSS THE MOUNTAINS AND ADJACENT PLAINS. THUS, EXPECT SOME IA  
CONCERN, THOUGH OVERALL, ONLY ELEVATED/NEAR CRITICAL CONDITIONS ARE  
EXPECTED ACROSS THE GUADALUPE AND DELAWARE MOUNTAINS, AND PERHAPS  
THE ADJACENT PLAINS, SATURDAY AFTERNOON SO A FIRE DANGER  
STATEMENT IS LIKELY TO BE ISSUED. THEREAFTER, A COLD FRONT WILL  
ARRIVE DURING THE DAY SUNDAY, ACCOMPANIED BY INCREASING MOISTURE  
AND MUCH COOLER, BELOW NORMAL TEMPERATURES ON MONDAY. THERE WILL  
ALSO BE A CHANCE FOR RAIN/SNOW SUNDAY NIGHT INTO MONDAY, MAINLY  
ALONG AND EAST OF THE PECOS RIVER. FIRE WEATHER CONCERNS BEYOND  
SATURDAY WILL BE LOW.
