.PREV DISCUSSION... /ISSUED 236 PM CST THU NOV 26 2009/ 

DISCUSSION...
WINDS WILL SHIFT SOUTHWEST TONIGHT AS SURFACE HIGH PRESSURE 
MOVES OFF TO THE EAST. ABOVE NORMAL TEMPERATURES WILL PREVAIL 
FRIDAY AND SATURDAY ALTHOUGH LOWS TONIGHT WILL REMAIN VERY 
COOL WITH THE MOSTLY CLEAR SKIES AND LIGHT WINDS.  

THE SOUTHERLY WINDS WILL PULL MOISTURE AHEAD OF AN UPPER LEVEL 
SYSTEM THAT WILL BRING CHANCES FOR RAIN ALONG WITH COOLER 
TEMPERATURES ON SUNDAY AND MONDAY. SLIGHTLY BETTER AGREEMENT IN 
THE MEDIUM RANGE MODELS BUT STILL HAVE QUESTIONS ON EXACT TIMING  
AND TRACK WHICH WOULD DETERMINE WHEN AND WHERE RAIN CHANCES NEED 
TO BE. BUT CONFIDENCE REMAINS ON THE LOW SIDE. 

WHAT DOES APPEAR SIGNIFICANT AND WILL BE WATCHED IS A POOL OF VERY 
COLD AIR FROM CANADA BRINGING VERY COLD TEMPERATURES TO OUR AREA 
TOWARDS THE END OF NEXT WEEK.
