CHALLENGE OF DAY ANY RAIN TONIGHT OR AGAIN SATURDAY NIGHT.

DEWPOINTS STILL UP...LIS STILL DOWN...MAIN WINDSHIFT CROSSING CWA.
EASY TO GET SURPRISES IN SUCH SITUATIONS. HOWEVER...SHIELD OF CLOUDS
IN FRONTAL ZONE HAS RESTRAINED HEATING. NO EVIDENCE OF CUMULIFORM
DVLPMNT FROM SATELLITE. THIS MORE THAN ANYTHING HAS CONVINCED ME TO
ACCEPT MOS AND KEEP IT DRY OVRNGT.

FRONT SHOULD *FINALLY* MOVE SOUTH OF INDIANA OVERNIGHT...BUT MODELS
CONTINUE TO HINT AT WK IMPULSES MOVG ALONG IT INTO SUNDAY WITH
STRONGEST TMRW NIGHT. THIS CERTAINLY PLAUSIBLE IN ZONAL FLOW. ALL
MODELS BRING BACK DECENT MOISTURE SAT NGT WITH AVN MOST AGRESSIVE.

LIKE AVN SOLN WITH MOISTURE COMING RELATIVELY FAR NORTH WITH FALLING
HGTS ALL MODELS SHOW TO DRAW IT UP...COMMON PATTERN A LITTLE LATER
IN THE YEAR. USING MAINLY MAV FOR POPS. EVEN THESE ARENT THAT
WET...ITS JUST A CHC NEEDED IN SOME AREAS.

FOR TEMPS...DID NOT LIKE THE WAY EITHER GUIDANCE WARMS UP SUNDAY. AS
LONG AS FRONT STAYS TO SOUTH DONT SEE ANY SUPPLY OF AIR THAT WARM.
OTHERWISE MAV/FWC CLOSE...AGREED OK WITH AIR THAT WILL BE OVER
US...SO MADE ONLY MINOR CHANGES.

.IND...NONE.
