INTO THE 60S AND DEWPOINTS RISE INTO THE MID AND UPPER 50S...SOME OF
THESE STORMS MAY BECOME SEVERE WITH THE PRIMARY THREATS BEING LARGE

NORTH OF THAT LINE MAY STILL EXPERIENCE THUNDERSTORMS CAPABLE OF
PRODUCING LARGE HAIL.

AT THIS TIME APPEARS TO BE LARGE HAIL AROUND THE SIZE OF QUARTERS. A
FEW SEVERE THUNDERSTORMS WILL BE POSSIBLE AGAIN TUESDAY AFTERNOON AND
EVENING ACROSS THE OUTLOOK AREA. THE BEST POTENTIAL FOR ANY SEVERE
WEATHER TUESDAY WILL BE MAINLY ALONG AND SOUTH OF A FRONTAL ZONE...
