...FAST-MOVING SQUALL LINES WILL GENERATE WIND DAMAGE...

TWO WELL DEVELOPED...AND INCREASINGLY MATURE...SQUALL LINES HAVE
EVOLVED ACROSS OK INTO THE RED RIVER REGION OF NORTH TX.  LEAD
SQUALL LINE IS EXITING NERN MOST QUADRANT OF WW45...MOVING INTO
WW46-47...WHILE UPSTREAM SQUALL LINE IS GRADUALLY DEVELOPING INTO
NCNTRL TX ALONG THE RED RIVER REGION.

BOTH OF THESE ORGANIZING COMPLEXES ARE RACING ENEWD IN EXCESS OF 50
KT AND SHOULD EASILY GENERATE DAMAGING WINDS...AS HAVE BEEN OBSERVED
ON SEVERAL MESONET LOCATIONS.  OF PARTICULAR INTEREST IS THE
POTENTIAL FOR SWD DEVELOPMENT ALONG ADVANCING WIND SHIFT INTO THE
METROPLEX AS STRONG FORCING OVERSPREADS WARM SECTOR.  ALTHOUGH
ISOLATED TORNADOES REMAIN POSSIBLE...STRONG WINDS APPEAR TO BE THE
GREATEST SEVERE THREATS WITH THESE SQUALL LINES.
