NOT SURE OF EXACT LOCATION OF FNT.  RW/TRW FORMED PAST HR JUST W OF
CMH ALONG LOW CLD/FH & PS (MORE HTG) INTERFACE...POSSIBLY WRM FNT
LOCATION.  STREAMLINE PLOT SHOWS WK CONVERGENCE THERE (5 KT WIND).

SCT RW/TRW OVER NW 1/4 OF OH OUT AHEAD OF MAIN MCS OVER LK MI.
FNTL BNDRY IS TROUBLESOME SINCE NW STEERING FLOW TAKING STORMS
ALONG SLOW MOVG BNDRY.  THINKG IS THAT STORMS WILL BE SCT.  COULD
BE A PROBLEM IF THEY TRACK OVER SAME AREAS HIT BY RECENT HEAVY
RAINS...BUT OVERALL BELIEVE ANY FLOODING WILL BE HIGHLY LOCALIZED
TNGT...IF IT EVEN OCCURS.

MODELS KEEP REGION IN UNSTABLE AND HUMID AIRMASS BUT WITH NO REAL
S/W`S TO ORGANIZE CONVECTION.  500H DIFFLUENT OVER AREA THRU
THE PD...HINTG AT DIVERGENCE ALOFT.  WL NOT TAKE MUCH IN THIS

WAY TO GO UNTIL RIDGG FINALLY DOMINATES ON FRI WhITH DRIER MEAN RH.
