THE SEVERE WEATHER THREAT FOR TORNADO WATCH 199...200...CONTINUES.

SUMMARY...WW/S 199/200 ARE SCHEDULED TO EXPIRE AT 09Z. REPLACEMENT
WW ISSUANCE IS UNLIKELY...BUT LOCAL TEMPORAL EXTENSION IS POSSIBLE
WITH A RISK FOR STRONG WIND GUSTS AND PERHAPS A BRIEF/WEAK TORNADO
IN ASSOCIATION WITH AN MCV EVOLVING NNE FROM THE METROPLEX.

DISCUSSION...MCV OVER THE NRN PORTION OF THE METROPLEX CURRENTLY IS
MOVING N AROUND 40 KT ALONG THE I-35 CORRIDOR. LARGER-SCALE
CONVECTIVE OUTFLOW BOUNDARY IS EVIDENT IN 08Z SURFACE ANALYSIS FROM
MARSHALL TO ADAIR COUNTY OK. IT APPEARS PLAUSIBLE THAT THIS MCV
SHOULD CONTINUE ITS NWD TRACK TOWARDS THE RED RIVER BEFORE SHIFTING
MORE NELY OVER SERN OK. GIVEN RECENT MEASURED WIND GUSTS TO NEAR 40
KT IN THE PAST HOUR /KDAL AND KRBD/...THESE MAY BE CAPABLE OF
ISOLATED DAMAGE. WITH WARM SECTOR AIR OVER NERN TX/SERN OK
CHARACTERIZED BY LOWER 70S SURFACE TEMPS AND NEAR 70 DEW
POINTS...TRANSIENT/WEAK MESOVORTICES WILL REMAIN
POSSIBLE...ESPECIALLY AS THE MCV INTERACTS WITH THE LARGER-SCALE
OUTFLOW BOUNDARY.
