MESOSCALE DISCUSSION 2054
NWS STORM PREDICTION CENTER NORMAN OK
0512 PM CDT THU OCT 01 2009

AREAS AFFECTED...EASTERN OK/WESTERN AR/SOUTHERN MO

CONCERNING...SEVERE THUNDERSTORM WATCH 751...

VALID 012212Z - 012345Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 751
CONTINUES.

SEVERE TSTM WATCH 751 CONTINUES UNTIL 00Z...WITH A CONTINUED RISK
FOR SEVERE WINDS/HAIL.

A NNE-SSW ARCING BROKEN LINE OF STORMS WILL CONTINUE TO STEADILY
PROGRESS GENERALLY EAST-SOUTHEASTWARD EARLY THIS EVENING ACROSS
PORTIONS OF SOUTHERN/EASTERN MO AND FAR SOUTHEAST OK/WESTERN AR AND
THE ADJACENT ARKLATEX. A FEW QUASI-DISCRETE/BRIEF SUPERCELLS WILL
REMAIN POSSIBLE...BUT AMPLE FRONTAL FORCING IS SUGGESTIVE OF A
TENDENCY FOR AN INCREASINGLY DENSE AREAL COVERAGE/LINEAR CONVECTIVE
MODE THROUGH THE EARLY EVENING HOURS. GIVEN AMPLE CLOUD
COVER/MARGINAL BUOYANCY TO THE EAST OF WW 751 ACROSS MO...AN
ADDITIONAL WATCH IS NOT ANTICIPATED FOR THE REMAINDER OF
SOUTHERN/EASTERN MO. HOWEVER...PORTIONS OF AR AND THE ADJACENT
ARKLATEX...WITH A WARMER/MORE MOIST AIRMASS IN PLACE IN SPITE OF
CONSIDERABLE CLOUD COVER...WILL CONTINUE TO BE MONITORED FOR THE
POSSIBILITY OF AN ADDITIONAL WATCH ISSUANCE.
