DATA( AFWA FOR ETA...NAVY NOGAPS FOR GFS)...WILL NOT MAKE SWEEPING
CHANGES TO CURRENT FCST.  CHANGES WILL FOCUS MORE ON THE SHORT
TERM...WHICH INVOLVES TODAY AND THURSDAY.

CURRENT KILN RADAR SHOWS SOME WIDELY SCATTERED SHRA/TSRA ACTIVITY
JUST TO THE N OF CWFA.  MORE THUNDERSTORMS WERE ERUPTING OVER SW
MICHIGAN NEAR COLD FRONTAL BOUNDARY/WEAK SFC LOW.  FOR TODAY...WITH
LACK OF SIGNIFICANT UPR SUPPORT...THUNDERSTORMS SHOULD NOT BECOME
WIDESPREAD.  HOWEVER...AS AFOREMENTIONED FRONT APCHS FROM THE
NW...EXPECT BEST CHC/S THIS AFTN TO BE ACRS THE N
(WAPOK...DAY...CMH...AROUND 40 PERCENT).  FOR THE SOUTH...PREVIOUS
MODEL SOUNDINGS WERE SHOWING A DECREASE IN THE STRONG CAPPING
INVERSION AROUND 850 MB.  THUS...BELIEVE THERE WILL BE MORE BUILDUPS
ACRS THE SOUTH THAN YESTERDAY...AND A 30 PERCENT CHC IS WARRANTED.
FCST TEMPS LOOK OK AT THIS POINT.

FOR TONIGHT...FRONT WILL MOVE SLOWLY SOUTH ACRS CWFA BEFORE STOPPING
SOMEWHERE OVER SRN OHIO.  AGAIN...WITH LACK OF SIGNIFICANT UPR
SUPPORT AND LOW LVL FORCING...BELIEVE CONVECTION WILL GRADUALLY
DISSIPATE TOWARD MIDNIGHT...AND WILL WORD ZONES THIS WAY.

ON THURSDAY...FRONTAL BOUNDARY WILL MOVE NORTH AS A WEAK WARM
FRONT...ALLOWING HUMID AIR TO OVERTAKE THE ENTIRE CWFA ONCE AGAIN.
WITH UNSTABLE AIRMASS...CAN NOT RULE OUT AN ISOLD AFTN/EVENING
THUNDERSTORMS.

NEXT SIGNIFICANT FRONT IS EXPECTED ACRS THE CWFA FRIDAY INTO
SATURDAY.

.ILN...NONE.
