AREAS AFFECTED...NERN OK...SERN KS...SW MO...NWRN AR
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 261754Z - 262000Z
ISOLATED SEVERE HAIL REPORTS...GENERALLY OF 1" OR LESS IN
DIAMETER...ARE EXPECTED. A WW IS NOT LIKELY.
A CLUSTER OF ELEVATED THUNDERSTORMS HAS FORMED ON THE NOSE OF AN 850
JET WHERE WARM/MOIST ADVECTION WAS OCCURRING. ALTHOUGH INSTABILITY
IS NOT HIGH...PRESENCE OF STEEP MID LEVEL LAPSE RATES WITH 500 MB
TEMPS COOLER THAN -20 C SUGGEST THE FORMATION OF HAIL WILL EASILY
OCCUR. ENOUGH DEEP SHEAR IN THE CLOUD BEARING LAYER FURTHER SUGGESTS
A FEW OF THE STRONGER CORES MAY PERSIST FOR SEVERAL COUNTIES WITH A
THREAT OF SOME HAIL.
