THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE

SURROUNDING THE MODERATE RISK AREA...THERE IS A SLIGHT RISK OF
SEVERE THUNDERSTORMS FROM THE EASTERN GULF COAST TO THE MID
MISSISSIPPI VALLEY AND UPPER GREAT LAKES.

VERY STRONG JET STREAM WILL TRANSLATE ACROSS THE MID MISSISSIPPI
VALLEY INTO LOWER MI LATER THIS EVENING.  THIS STRONG DISTURBANCE

SHARPEN ATTENDANT FRONTAL BOUNDARY EXPECTED TO ARC SOUTHWARD ACROSS
WI...IL INTO AR BY EARLY EVENING.

VERY MOIST BUOYANT AIRMASS WILL SPREAD NORTHWARD AHEAD OF THIS
FRONTAL SYSTEM WHICH WILL CREATE A FAVORABLE ENVIRONMENT FOR SEVERE

KY/WRN TN THIS EVENING.  STORM ROTATION IS LIKELY WITH MANY STORMS

SEGMENTS.

WHILE THE GREATEST SEVERE COVERAGE IS EXPECTED ACROSS THE TN/LOWER
