MESOSCALE DISCUSSION 1449
NWS STORM PREDICTION CENTER NORMAN OK
0606 PM CDT WED JUL 23 2014

AREAS AFFECTED...NERN TX...SRN AR AND NRN LA

CONCERNING...SEVERE THUNDERSTORM WATCH 431...434...

VALID 232306Z - 240030Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
431...434...CONTINUES.

SUMMARY...STORMS WILL CONTINUE TO POSE A THREAT FOR STRONG TO
DAMAGING WIND GUSTS UNTIL MID EVENING FROM NERN TX THROUGH SRN AR
AND NRN LA. A NEW WW WILL LIKELY BE REQUIRED SOUTH OF WW 434 TO
INCLUDE NERN TX AND NWRN LA.

DISCUSSION...A LARGE MCS WITH EXPANSIVE TRAILING COLD POOL AND
STRATIFORM REGION EXTENDS FROM E-CNTRL AR SWWD THROUGH EXTREME NERN
TX INTO EXTREME SERN OK MOVING SOUTH AT 30-35 KT. THE LATEST
OBJECTIVE ANALYSIS INDICATES THE STORMS ARE CURRENTLY MOVING THROUGH
AXIS OF MAXIMUM CAPE. HOWEVER...DOWNSTREAM WARM SECTOR REMAINS
MODERATELY UNSTABLE WITH TEMPERATURES AROUND 90F AND 70F DEWPOINTS.
GIVEN THE MOIST SFC LAYER...WEAK CAP AND STRONG CONVERGENCE ALONG
THE GUST FRONT...STORMS SHOULD CONTINUE DEVELOPING SWD NEXT 3-4
HOURS BEFORE THE STABILIZING BOUNDARY LAYER CONTRIBUTES TO THE
ULTIMATE DEMISE OF THE MCS LATER THIS EVENING.
