DISCUSSION...  
SURFACE HIGH PRESSURE CENTERED OVER THE HEART OF THE ARK-LA-TEX  
THIS MORNING UNDER MOSTLY CLEAR SKIES HAS ALLOWED FOR NEAR-PRIME  
RADIATIONAL COOLING CONDITIONS. TEMPERATURES AS OF THE LATEST 10Z  
OBSERVATIONS RANGE FROM THE MID 20S NORTH TO MID 30S SOUTH WITH A  
FEW MORE DEGREES LEFT TO FALL EVEN WITH SOME QUICK PASSING CIRRUS  
MOVING THROUGH THE COLD NW FLOW ALOFT. CIRRUS WILL LIKELY EXIT THE  
AREA BY DAYBREAK WITH ABUNDANT SUNSHINE EXPECTED THIS THANKSGIVING  
DAY AS DAYTIME HIGHS REACH BACK TOWARD 60 DEGREES THIS AFTERNOON.  
ANOTHER CHILLY NIGHT LIES AHEAD, ALBEIT NOT QUITE AS COLD AS THIS  
MORNING AS LOWS WILL RANGE THROUGH THE 30S ACROSS MOST OF THE AREA.  
A WARMING TREND WILL BEGIN TO TAKE SHAPE BY FRIDAY AS SOUTHERLY  
WINDS RETURN TO THE REGION WITH HIGH PRESSURE SHIFTING EAST OF OUR  
FORECAST AREA. THIS WILL SEND OUR TEMPERATURES BACK CLOSER TO  
SEASONAL AVERAGES AND EVEN ABOVE AVERAGE BY SATURDAY AS LOW TO MID  
70S ARE EXPECTED IN ADVANCE OF OUR NEXT COLD FRONT ARRIVING LATER  
IN THE DAY ON SATURDAY. THIS FRONT WILL BE RATHER UNEVENTFUL WITH  
LITTLE MORE THAN A WIND SHIFT BACK TO THE NORTH FOR SUNDAY AND  
VERY MINIMAL IMPACT ON TEMPERATURES. UPPER RIDGING WILL BEGIN TO  
NUDGE CLOSER TO THE REGION BY SUNDAY WITH AFTERNOON HIGHS PUSHING  
EITHER SIDE OF 70 DEGREES.  
 
THE UPPER RIDGE TO OUR SOUTHWEST WILL BECOME EVEN MORE INFLUENTIAL  
EARLY NEXT WEEK WITH TEMPERATURES WARMING A BIT MORE ON MONDAY AND  
EVEN INTO TUESDAY BEFORE OUR NEXT COLD FRONT IS DUE TO ARRIVE LATE  
TUESDAY. THIS FRONT WILL HAVE SLIGHTLY MORE MOISTURE TO WORK WITH  
COMPARED TO THE LAST FEW SO HAVE CONTINUED TO ADVERTISE SLIGHT TO  
LOW CHANCE POPS FOR TUESDAY INTO WEDNESDAY WITH THE PASSAGE OF THE  
FRONT. PROJECTED RAINFALL AMOUNTS ARE STILL LESS THAN IMPRESSIVE  
SO DON'T EXPECT MUCH IF ANY RELIEF IN ONGOING DROUGHT CONDITIONS.  
THE REMAINDER OF NEXT WEEK THROUGH FRIDAY LOOKS DRY AND SEASONAL  
AS TEMPERATURES GO AS WE TURN THE PAGE FROM NOVEMBER TO DECEMBER.
