AREAS AFFECTED...NERN KS / WRN MO / NRN AR / SWRN IA / ERN NE

CONCERNING...SEVERE THUNDERSTORM WATCH 577...579...

VALID 192311Z - 200015Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
577...579...CONTINUES.

ONGOING STRONG TO SEVERE THUNDERSTORMS WILL LIKELY WEAKEN OVER THE
NEXT FEW HOURS ACROSS MOST OF THE MID-MISSOURI RIVER VALLEY / OZARKS
REGIONS.

RECENT TRENDS IN RADAR MOSAIC SUGGEST A TENDENCY FOR MORE STORM
INTERACTIONS/DESTRUCTIVE MERGERS...ESPECIALLY ACROSS NWRN MO INTO
E-CENTRAL KS. THE ATMOSPHERE WILL TEND TO GRADUALLY STABILIZE AS
WELL...PROMOTING A WEAKENING TREND.

DISCRETE STORMS ACROSS ERN/NERN NEBRASKA AND OVER THE OZARK REGION
APPEAR TO POSE THE MOST SUBSTANTIAL SEVERE THREAT THROUGH 01Z. AREA
WSR88-D VAD/PROFILERS CONTINUE TO SHOW MARGINAL LOWER-MID
TROPOSPHERIC FLOW /AROUND 30KTS OR LESS 0-6 KM SHEAR/...INDICATING
STRONG TO SEVERE MULTICELLS MAY BECOME THE DOMINANT STORM MODE. ANY
SEVERE ACTIVITY ASSOCIATED WITH THESE STORMS WILL TEND TO BE
DAMAGING WIND GUSTS WITH ISOLATED LARGE HAIL POSSIBLE. STORMS
REMAINING DISCRETE WILL POSE MORE OF A THREAT FOR LARGE HAIL...IN
ADDITION TO DAMAGING WINDS.
