.PREV DISCUSSION... /ISSUED 901 PM CST THU DEC 24 2009/ 

UPDATE...
WILL SEND AN UPDATE TO ADJUST CLOUD COVER OVER THE SOUTHERN CWA...
WITH ONLY MINOR TWEAKS ELSEWHERE.

DISCUSSION...
NORTHERLY WINDS CONTINUED TO DECREASE OVER THE WESTERN LOW ROLLING 
PLAINS THIS EVENING...WHILE MAINLY LIGHT WINDS WERE FOUND OVER THE 
REST OF THE AREA UNDER THE INFLUENCE OF A RESIDENT SURFACE RIDGE.  
THIS SURFACE RIDGE WILL ONLY MOVE SLIGHTLY EASTWARD OVERNIGHT... 
WITH GENERALLY LIGHT WINDS AND CLEAR SKIES MAKING FOR GOOD 
RADIATIONAL COOLING CONDITIONS...FOR THE MOST PART.  HIGH CLOUDS 
WERE ALREADY SPREADING INTO PORTIONS OF THE PRESIDIO VALLEY THIS 
EVENING...AND EXPECT THE CLOUDS TO INCREASE FURTHER AND THICKEN A 
BIT...ALONG AND SOUTH OF INTERSTATE 10 IN PARTICULAR...AS THE RRQ OF 
A H25 JET TRAVERSES THE AREA OVERNIGHT.  WILL ADJUST TEMPERATURES UP 
A LITTLE IN THESE AREAS AS RADIATIONAL COOLING WILL LIKELY BE 
SABOTAGED.  ACTUALLY LOWERED TEMPERATURES IN SOME LOCATIONS ACROSS 
THE NORTHERN ZONES...AND IN AREAS WHERE SNOW COVERED THE GROUND.  
CONSEQUENTLY...IF MIDLAND REACHES A LOW OF 16...AS FORECAST...IT 
WILL BE THE 3RD COLDEST CHRISTMAS DAY ON RECORD.  MADE ONLY MINOR 
WIND AND DEWPOINT ADJUSTMENTS OTHERWISE...SO AN UPDATE WILL FOLLOW 
SHORTLY.
