AREAS AFFECTED...SRN IL...SWRN IND...WRN KY...NWRN TN

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 151913Z - 152115Z

STORMS ARE INCREASING IN COVERAGE. LARGE HAIL WILL BE THE MAIN
THREAT...A WATCH MAY BE CONSIDERED.

STORMS ARE INCREASING IN COVERAGE NOW NEAR A LOW DRYLINE/LOW
PRESSURE TROUGH FROM CNTRL IL SWD ALONG THE MS RIVER. HEATING
PERSISTS IN THE WAKE OF EARLIER CONVECTION...AND CAPPING HAS BEEN
REMOVED. AN OUTFLOW BOUNDARY DOES EXIST ACROSS ERN IL INTO SWRN IND
AND CNTRL KY...WITH COOLER AND STABLE AIR TO THE E. THIS IS
RESULTING IN A RATHER NARROW MOIST SECTOR ACROSS CNTRL IL...BUT
WIDENING OVER WRN KY.

LOW LEVEL SHEAR AWAY FROM THE OUTFLOW BOUNDARY IS MEAGER WITH WINDS
VEERING/MIXING. BUT DEEP LAYER SHEAR AND RELATIVELY STRAIGHT
HODOGRAPHS ARE FAVORABLE FOR A FEW SUPERCELLS CONTAINING LARGE HAIL.
LOW LEVEL SHEAR IS STRONG NEAR THE OUTFLOW BOUNDARY BUT THE
EFFECTIVE ZONE WHERE PARCELS WOULD REMAIN UNSTABLE MAY BE QUITE
NARROW. STORMS WOULD HAVE TO TURN SUBSTANTIALLY TO THE RIGHT NEAR
THIS BOUNDARY IN ORDER TO HAVE AN INCREASED TORNADO THREAT.
