TO LUDINGTON THEN ANGLING SOUTHWEST DOWN THE LAKE TOWARD NORTHEAST

J/KG THIS AFTERNOON WITH LI/S DROPPING TO NEAR -9 C. EXPECTING MORE

SHEAR ON THE WEAKER SIDE. ORGANIZATION WILL BE PROVIDED HOWEVER VIA
LIFT FROM THE UPPER SHORTWAVE. HAIL WILL BE THE MAIN
THREAT...ALTHOUGH WET MICROBUST SEVERE WINDS CANNOT BE RULED OUT.
THE THREAT FOR SEVERE SHOULD GRADUALLY MOVE SOUTH AND EAST WITH TIME
AS THE SHORTWAVE MOVES EAST AND THE COOL FRONT SAGS SOUTH.
