SHORT TERM
 
 
(TONIGHT AND FRIDAY)  
 
EXPECT GUSTY SOUTH TO SOUTHWEST WINDS TO SLOWLY DECREASE THROUGH THE  
OVERNIGHT HOURS WITH OVERNIGHT LOW TEMPERATURES IN THE LOW TO MID  
60S. STRATUS DEVELOPMENT IS EXPECTED AFTER MIDNIGHT, WHICH WILL  
OVERSPREAD THE SOUTHERN HALF OF THE FORECAST AREA. A WEAK COLD FRONT  
WILL MOVE INTO THE BIG COUNTRY DURING THE MORNING HOURS, WITH THE  
THE ONLY EFFECT BEING A WIND SHIFT TO THE NORTH AT 5 TO 10 MPH.  
 
MORNING CLOUD WILL QUICKLY DISSIPATE BY MID TO LATE MORNING AS A  
DRYLINE QUICKLY ADVANCES EAST, MAKING IT INTO OUR FAR EASTERN  
COUNTIES BY EARLY AFTERNOON. EXPECT AFTERNOON HIGH TEMPERATURES WELL  
ABOVE SEASONAL NORMALS, ALONG WITH WEST TO SOUTHWEST WINDS OF 10 TO  
15 MPH. HIGHS WILL GENERALLY BE IN THE LOW TO MID 90S, WITH A FEW  
LOCATIONS APPROACHING THE UPPER 90S. ISOLATED SHOWERS AND  
THUNDERSTORMS WILL BE POSSIBLE ACROSS THE EXTREME NORTHEAST PORTIONS  
OF THE BIG COUNTRY, ALTHOUGH MOST OF THE CONVECTION IS FORECAST TO  
REMAIN EAST OF THE FORECAST AREA.  
 
DANIELS  
   
LONG TERM
 
 
(FRIDAY NIGHT)  
   
..POSSIBLE SEVERE THUNDERSTORMS
 
 
THE DRYLINE, INTERACTING WITH AN OLD FRONTAL BOUNDARY JUST TO OUR  
NORTH, COULD INITIATE A FEW SEVERE THUNDERSTORMS FRIDAY NIGHT.  
THE MAIN AREA OF CONCERN LIES MAINLY NORTH AND EAST OF A  
SWEETWATER TO BROWNWOOD LINE. THAT'S WHERE A SO-CALLED TRIPLE  
POINT WILL BE NEAR; THE TIPPLE POINT IS THE POINT WHERE THE  
DRYLINE MEETS THE OLD FRONTAL BOUNDARY.  
 
(SATURDAY AND SATURDAY NIGHT)  
   
..RAIN POTENTIAL CONTINUES
 
 
AS THE UPPER LOWS CONTINUES TO MOVE OUT OF THE SOUTHERN ROCKIES  
AND INTO THE SOUTHERN PLAINS SATURDAY AND SATURDAY NIGHT, THE  
ASSOCIATED UPPER TROUGH WILL MOVE OVER WEST CENTRAL TEXAS. THIS  
TROUGH, ALONG WITH A WEAK SURFACE COLD FRONT AND DRYLINE, WILL  
CREATE THE POTENTIAL FOR ADDITIONAL SHOWERS AND THUNDERSTORMS,  
ACROSS WEST CENTRAL TEXAS. ALTHOUGH THE THREAT OF SEVERE  
THUNDERSTORMS WILL PUSH EAST OF OUR AREA SATURDAY NIGHT, SOME  
THUNDERSTORMS COULD PRODUCE DAMAGING HAIL AND WINDS.  
 
(SUNDAY THROUGH THURSDAY)  
 
FOR SUNDAY INTO LATE NEXT WEEK, LOOK FOR DRY CONDITIONS, WITH  
SOME TEMPERATURE SWINGS. AS THE UPPER LOW CONTINUES ITS EASTWARD  
MIGRATION ON SUNDAY, COOLER AIR BEHIND ITS ASSOCIATED COLD FRONT  
WILL HELP HOLD AFTERNOON HIGHS MAINLY IN THE MID 60S TO LOWER 70S  
RANGE; THAT'S MUCH CLOSER TO SEASONAL NORMALS. THEN, AS THE UPPER-  
LEVEL PATTERN MODIFIES, AND HIGH PRESSURE BECOMES MORE DOMINATE,  
SOUTHERLY LOW-LEVEL FLOW WILL RETURN AND SIGNAL THE START OF A  
WARMING TREND. THIS WARM-UP WILL THEN CONTINUE THROUGH MID WEEK.  
HOWEVER, ANOTHER COLD FRONT, DURING THE DAY WEDNESDAY, WILL BRING  
WINDS FROM THE NORTH AND COOLER AIR.
