AREAS AFFECTED...WESTERN/NORTHERN ARKANSAS INTO SOUTH-CENTRAL
MISSOURI.
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 181822Z - 181945Z
PROBABILITY OF WATCH ISSUANCE...5 PERCENT
SUMMARY...ISOLATED DAMAGING WIND GUSTS ARE POSSIBLE THIS
AFTERNOON/EVENING.
DISCUSSION...THUNDERSTORMS ARE STARTING TO DEVELOP ACROSS THE OZARKS
FROM WESTERN ARKANSAS INTO SOUTH-CENTRAL MISSOURI. THESE STORMS ARE
FORMING WITHIN AN ENVIRONMENT WITH SOMEWHAT MORE FAVORABLE MID-LEVEL
LAPSE RATES (~7 C/KM PER SGF/LZK 12Z RAOB) AND HOT TEMPERATURES NEAR
100 DEGREES. WEAK SHEAR (10 KNOTS OR LESS THROUGH THE ENTIRE
TROPOSPHERE) WILL LIMIT STORM ORGANIZATION. DESPITE THE UNORGANIZED
NATURE OF THE CONVECTION, STRONG HEATING/INSTABILITY WILL SUPPORT
STRONGER STORMS CAPABLE OF ISOLATED MICROBURSTS AND WIND DAMAGE. A
SEVERE THUNDERSTORM WATCH WILL NOT BE ISSUED FOR THIS
SPORADIC/ISOLATED THREAT.
