343 PM CDT TUE AUG 17 2010

.DISCUSSION...
THUNDERSTORMS ARE STARTING TO INITIATE ON A BOUNDARY ALONG A
GRAHAM TO BOWIE TO ADA LINE. STORM MOTION WITH THESE STORMS WILL
BE SOUTHEAST AT 10 TO 12 KTS SO THEY WILL LIKELY ENTER THE
NORTHWEST ZONES SHORTLY. DCAPE VALUES RANGE FROM 800 TO 1000 J/KG AND
MAX THETA-E DIFFERENCES RANGE FROM 17 TO 20 SO STRONG MICROBURSTS
ARE POSSIBLE WITH ANY STORMS THAT DO DEVELOP. GOOD NORTHWEST FLOW
BEHIND THE BOUNDARY SHOULD ALLOW IT TO MOVE THROUGH THE NORTHERN
CWA OVERNIGHT AND PUSH TO THE SOUTHERN CWA TOMORROW. POPS FOLLOW
THE MOVEMENT OF THIS BOUNDARY WITH 30 POPS IN THE NORTHWEST THIS
AFTERNOON THEN 20 POPS SOUTH OF A COMANCHE TO HILLSBORO TO ATHENS
LINE TOMORROW.

NORTH FLOW AND LOWER DEWPOINTS SHOULD FILTER IN BEHIND THE FRONT
TOMORROW. AS SUCH...WILL NOT MEET HEAT INDEX CRITERIA TOMORROW
AFTERNOON. HEAT INDEX VALUES WILL RANGE FROM 100 TO 103 NORTH OF
THE BOUNDARY AND 103 TO 105 SOUTH OF THE BOUNDARY. THEREFORE WE
WILL NOT MEET AFTERNOON HEAT INDEX CRITERIA TOMORROW NORTH OF THE
BOUNDARY AND NOT MEET OVERNIGHT LOW CRITERIA TONIGHT SOUTH OF THE
COMANCHE TO HILLSBORO TO ATHENS LINE. AS SUCH...HEAT ADVISORY WILL
BE ALLOWED TO EXPIRE TONIGHT AT 8 PM.

DESPITE FROPA TONIGHT...SUBTROPICAL HIGH REMAINS IN CONTROL. THE
DRIER...COOLER AIR ASSOCIATED WITH THE WEAK COLD FRONT WILL BE
VERY SHALLOW. 850 MB TEMPS REMAIN ABOVE 20 DEGREES C SO HIGHS WILL
STILL BE IN THE UPPER 90S AND LOW 100S THROUGH THE WEEKEND.
NORTHWEST FLOW KEEPS TEMPS A LITTLE LOWER WEDNESDAY AND THURSDAY
AS THE UPPER LEVEL HIGH IS CENTERED OVER NORTHERN MEXICO. A
SHORTWAVE IS PROGGED TO MOVE THROUGH THE UPPER PLAINS
FRIDAY...WHICH SHIFTS THE CENTER OF THE HIGH TO THE SE CONUS AND
PUTS NORTH TEXAS IN SOUTHWEST FLOW SATURDAY. AS A RESULT...HIGHS
INCREASE TO NEAR 103 AGAIN AND HEAT INDEX VALUES APPROACH 105.
SO...EVEN THOUGH THE CURRENT HEAT ADVISORY WILL EXPIRE...A NEW ONE
LOOKS LIKELY THIS WEEKEND. GIVEN THE CURRENT TRENDS...THE WARMEST
DAY IN THE SEVEN DAY FORECAST WILL BE SUNDAY OR MONDAY WHERE
HIGHS WILL BE BETWEEN 101 AND 103 FOR MOST OF THE CWA.
