AREAS AFFECTED...NWRN ND

CONCERNING...SEVERE POTENTIAL...WATCH LIKELY

VALID 020135Z - 020230Z

THE POTENTIAL FOR LARGE HAIL AND DAMAGING WINDS MAY CONTINUE FOR THE
NEXT FEW HOURS AND A WW WILL LIKELY BE REQUIRED.

ISOLATED...DIURNAL TSTMS ARE IN PROGRESS AS OF 0125Z OVER SWRN WARD
AND NRN DUNN COUNTIES. THE STORM IN NRN DUNN COUNTY HAS EXHIBITED
CYCLONIC ROTATION AND HAS PRODUCED HAIL UP TO TENNIS BALL SIZE.
LATEST SHORT TERM MODEL GUIDANCE REMAINS CONSISTENT IN SUGGESTING
THAT A SLY...NOCTURNAL LLJ WILL INTENSIFY ACROSS THE REGION OVER THE
NEXT FEW HOURS WHICH MAY SUPPORT ONGOING STORMS AND PROMOTE
ADDITIONAL DEVELOPMENT. GIVEN THE PRESENCE OF THE STEEP LAPSE RATES
AND MODERATELY STRONG VERTICAL SHEAR...ORGANIZED UPDRAFTS WILL
REMAIN POSSIBLE WITH THE THREAT FOR LARGE HAIL AND DAMAGING WINDS.
