AREA FORECAST DISCUSSION...CORRECTED TYPO
NATIONAL WEATHER SERVICE FORT WORTH TX
347 AM CDT THU APR 10 2008

.DISCUSSION...
SECOND ROUND OF SEVERE STORMS NOW MOVING QUICKLY WEST TO EAST
THROUGH NORTH TEXAS. A STOUT SQUALL LINE EXTENDS FROM NEAR
GAINESVILLE...TO CLEBURNE...TO GATESVILLE. FORWARD SPEED IS AROUND
50 KTS. THIS COMBINED WITH THE WINDS ASSOCIATED WITH THE LINE
ITSELF HAS BEEN CAUSING MAJOR DAMAGE IN THE FORM OF TREES AND
POWER LINES DOWN AS WELL AS SOME STRUCTURAL DAMAGE. REPORTS OF WIND
SPEEDS TO 80 MPH ARE COMMON. HAIL AND TORNADO REPORTS HAVE BEEN
SCARCE...ALTHOUGH A FEW CELLS ARE EXHIBITING ROTATION. THE SEVERE
WEATHER SHOULD BE JUST EAST OF THE CWA COINCIDENT WITH THE
EXPIRATION OF THE TORNADO WATCH AT 6 AM.  NEW TOR WATCH WILL BE
ISSUED FOR THE REMAINDER OF NORTH TEXAS NOT IN THE CURRENT WATCH.
FLASH FLOOD WATCH IS STILL IN EFFECT...ALTHOUGH SPEED OF THE SYSTEM
HAS SO FAR PRECLUDED MANY FLOODING PROBLEMS.

GUIDANCE CONTINUES TO SHOW WIND SPEEDS IN THE 20-30 KT RANGE THIS
AFTERNOON AS THE SURFACE LOW SWINGS TO OUR NORTH. HAVE ALREADY
ISSUED A WIND ADVISORY FOR THE ENTIRE AREA THROUGH 9 PM. GUSTS TO
40 MPH ARE LIKELY THIS AFTERNOON...ESPECIALLY IN THE NORTHERN HALF
OF THE FORECAST AREA. WINDS SHOULD DIE DOWN AS SURFACE LOW PULLS
OFF TO THE NORTHEAST AND PRESSURE GRADIENT RELAXES.

THE REMAINDER OF THE FORECAST LOOKS MUCH TAMER WITH NO POPS IN THE
FORECAST AFTER TODAY. SPRAWLING SURFACE HIGH WILL OCCUPY MUCH OF
THE CENTRAL U.S. INCLUDING NORTH TEXAS THROUGH THE REMAINDER OF
THE 7 DAY FORECAST.

STRONG SOUTHWEST WINDS ALONG WITH CLEARING SKIES SHOULD HELP
TEMPS TODAY REACH THE LOWER 80S AT MOST LOCATIONS. FROPA WILL
OCCUR TOMORROW MORNING KNOCKING HIGH TEMPS BACK INTO THE 60S AND
70S FOR FRIDAY AND SATURDAY. CONTINUED NORTH WINDS ON THE WESTERN
SIDE OF THE DEPARTING LOW PRESSURE SYSTEM ALONG WITH ANOTHER SHOT
OF COLD AIR WILL KEEP TEMPS DOWN SUNDAY AS WELL. MONDAY THROUGH
WEDNESDAY LOOK NICE AS TEMPERATURES REBOUND INTO THE 70S.  SH/13
