PROBLEM OF DAY IS GETTING HANDLING RAIN CHANCES THRU TOMORROW.

MCS OVER NE INDIANA LOOKS TO BE EVENING EVENT...BUT WILL COVER
EASTERN COUNTIES PRETTY THROUGHLY SO WILL BREAK OUT SEVERAL ZONES
ACCORDINGLY.

EVERY NIGHT WE HAVE BEEN GETTING SCATTERED STUFF EITHER FROM MCS
BRUSHING BY AND/OR VORT THAT FIRED MCS IN FIRST PLACE KICKING UP
SOMETHING IN THIS VERY WARM HUMID AIRMASS. NONE OF MODELS CHANGES
OVERALL SYNOPTIC PATTERN TOO MUCH...WHICH WOULD SUGGEST SOMETHING
FIRING TO OUR NW AGAIN TONIGHT AND BRUSHNG WRN COUNTIES SUNDAY
MORNING. AVN ALSO BRINGS IN A FEW WEAK IMPULSES ACRS ENTIRE
STATE...AND HAS BEEN MORE OR LESS CORRECT IN DOING SO IN RECENT PAST.

THIS MEANS RELATIVELY HIGH MAV POPS LOOK BETTER TO ME. THAT MAY COME
LATE TOMORROW AS RIDGE ALOFT GRADUALLY FLATTENS...ALLOWING WRMER AIR
TO COME EAST AND SUBSIDENCE INVERSION  TO DVLP. FCSTNG SUNDAY NGT TO
FINALLY BE DRY. UNFORTUNATELY...AS RDG CONTINUES TO FLATTEN CDFNT
MAY APPROACH BY LATE MONDAY...CALLING FOR SMALL CHC AGAIN.

NO BIG CHANGES IN TEMPS UNTIL WE CHANGE THE AIRMASS. HOWEVER IF WE
DEVELOP A CAP BEGINNING TOMORROW WE MAY GET A LITTLE WARMER.
GUIDANCE SEEMS TO REFLECT THIS WELL OVERALL BUT IS USUALLY A LTL
CONSERVATIVE ABOUT RAISING TEMPS IN SUCH SITUATIONS...SO MINOR
INCREASES IN ORDER SUNDAY INTO MONDAY.

.IND...NONE.
