SHORT TERM
 
 
(TODAY THROUGH SATURDAY)  
ISSUED AT 154 AM CST FRI DEC 2 2022  
 
IF ATTENDING ANY OUTDOOR HOLIDAY ACTIVITIES OR PUTTING UP ANY  
HOLIDAY DECORATIONS, THIS WEEKEND WILL BE A PERFECT OPPORTUNITY TO  
DO SO. MID-LEVEL HIGH PRESSURE BUILDS OVER THE CENTRAL UNITED  
STATES BRINGING WARMER WEATHER TO DEEP SOUTH TEXAS FOR THE  
WEEKEND. TODAY'S HIGHS WILL BE IN THE MID 70S WITH MOSTLY TO  
PARTLY CLOUDY SKIES. TONIGHT, LOWS WILL BE IN THE UPPER 60S WITH  
DEWPOINTS ALSO IN THE UPPER 60S. LIGHT SOUTHEASTERLY FLOW  
OVERNIGHT WILL CREATE A FAVORABLE ENVIRONMENT FOR DENSE FOG  
FORMATION. RIGHT NOW, THE SREF HAS MOST OF THE CWA COVERED IN  
DENSE FOG INTO SATURDAY MORNING. THE REST OF SATURDAY WILL BE  
PLEASANT WITH MOSTLY SUNNY SKIES AND HIGHS IN THE LOWER 80S.  
 

 
   
LONG TERM
 
 
(SATURDAY NIGHT THROUGH THURSDAY)  
ISSUED AT 154 AM CST FRI DEC 2 2022  
 
THE PATTERN ALOFT WILL FEATURE A BROAD, ROBUST MID-LEVEL RIDGE  
BUILDING NORTH INTO THE RGV/DEEP SOUTH TEXAS BY SATURDAY, WITH THE  
THE CENTER OF THE 500MB HIGH BRIEFLY OVER TAMAULIPAS STATE IN  
MEXICO. BY MONDAY/TUESDAY, THE RIDGE WILL BREAK DOWN A BIT TO  
YIELD A MODERATE SOUTHWEST OVERHEAD FLOW AS AN UPSTREAM MID-LEVEL  
LOW MOVES INTO N. CALIFORNIA. THIS WILL DISPLACE THE RIDGE/HIGH  
EASTWARD OVER THE GULF WHILE SHORT WAVE TROUGHS DIG INTO THE  
SOUTHWEST AND THEN EJECT NORTHEAST OVER THE RIDGE AND INTO THE  
PLAINS. OVERALL, THIS SHOULD YIELD A MAINLY DRY AND WARM PATTERN,  
WITH TEMPERATURES AROUND 10 DEG F ABOVE NORMAL FOR BOTH OVERNIGHT  
LOWS AND AFTERNOON HIGHS.  
 
WITH THE MAIN STORM TRACK WELL TO THE NORTH OF THE CWA, COLD  
FRONTS WILL HAVE A TOUGH TIME APPROACHING. HOWEVER, ONE FRONT  
WILL APPROACH ON SATURDAY, MOVING INTO SOUTH-CENTRAL TEXAS DURING  
THE DAY AND POSSIBLY REACHING A ROUGHLY CRP-LRD LINE SATURDAY  
EVENING. MODELS HAVE BEEN PRETTY CONSISTENT WITH THIS SCENARIO,  
YIELDING GOOD CONFIDENCE. WHILE THE SURFACE HIGH BEHIND THIS FRONT  
WILL BE ~1036 MB, ITS CORE WILL NEVER PASS FARTHER SOUTH THAN  
KANSAS, AND IT WILL SCOOT OFF TOWARD THE MIDWEST. ISOLATED SHOWER  
ACTIVITY WHICH WILL DEVELOP ON SATURDAY WILL LINGER INTO SUNDAY,  
BUT RAIN CHANCES WILL END SUNDAY NIGHT.  
 
LOOKING FARTHER OUT, THE FIRST PART OF THE NEW WORK WEEK WILL BE  
WARM AND BREEZY. ANOTHER FRONT MAY APPROACH AND WASH OUT OVER  
NORTH-CENTRAL TEXAS AROUND NEXT WEDNESDAY. WILL CONTINUE TO LEAN  
CLOSE TO NBM GUIDANCE IN THE LONG TERM.
