NWS STORM PREDICTION CENTER NORMAN OK
1111 AM CDT THU APR 16 2026
AREAS AFFECTED...SOUTHERN MISSOURI...NORTHERN ARKANSAS...PORTIONS OF
WESTERN TENNESSEE/KENTUCKY
CONCERNING...SEVERE POTENTIAL...WATCH LIKELY
VALID 161611Z - 161745Z
PROBABILITY OF WATCH ISSUANCE...80 PERCENT
SUMMARY...SEVERE RISK TO INCREASE THROUGH THE EARLY AFTERNOON.
PRIMARY RISKS WILL INCLUDE LARGE HAIL AND DAMAGING WIND.
DISCUSSION...VISIBLE SATELLITE ACROSS SOUTHERN MISSOURI SHOWS AN
AREA OF DEEPENING CU DEVELOPMENT, WITH A FEW SMALLER CELLS WITH
OCCASIONAL LIGHTNING DEVELOPING EAST OF SPRINGFIELD. THE 12Z RAOB
FROM SGF (SPRINGFIELD, MO) SHOWS MLCIN IN PLACE, WHICH CAN STILL BE
OBSERVED IN SURFACE OBJECTIVE ANALYSIS. WITH ADDITIONAL
HEATING/MIXING AND COOLING ALOFT WITH THE APPROACHING SHORTWAVE,
THIS IS EXPECTED TO ERODE OVER THE NEXT COUPLE OF HOURS.
HREF GUIDANCE SUGGESTS THAT A CLUSTER OF THUNDERSTORMS MAY DEVELOP
BY EARLY AFTERNOON BEFORE MOVING SOUTH AND EASTWARD INTO NORTHERN
ARKANSAS AS FORCING FOR ASCENT INCREASES. FORECAST SOUNDINGS DEPICT
LINEARLY ELONGATED HODOGRAPHS AND STEEP LOW TO MID-LEVEL HODOGRAPHS,
FAVORABLE FOR SUPERCELLS CAPABLE OF LARGE HAIL. THROUGH TIME, IT IS
LIKELY THAT STORMS WILL CLUSTER WITH AN INCREASE IN DAMAGING WIND
POTENTIAL. ADDITIONAL THUNDERSTORMS WILL BE POSSIBLE NEAR THE OK/AR
BORDER THIS AFTERNOON. A WATCH WILL LIKELY BE NEEDED TO COVER THESE
THREATS.
