FCST CONCERNS THIS CYCLE MAINLY ON PCPN CHCS.

BIG SLUG OF RAIN COMING THRU ATTM ON LEADING EDGE BEST H8 WAA. ASSOC
MID LEVEL S/W SHOWING UP WELL ON 88D LOOPS AND WV IMAGERY. AVN SEEMS
TO HAVE THE BEST LOCK ON ITS POSITION AND TRACK...DUE EAST TO SE
WI VCNTY BY 00Z SUN.  NOTHING HAPPENING UPSTREAM OF THIS COMPLEX ATTM
AND NOT SURE IF MORE WILL DVLP AHEAD OF SFC FNT TO THE WEST BEFORE IT
COMES THRU BEGINNING TWRD MORNING. MAIN REASON IS LACK OF ANY UPR
LEVEL KICKER WITH FNT...DRY SLOT ABOVE H8 ARRIVES AHEAD OF FNT...AND
LTL WAA. IN FAVOR OF PCPN IS THE SIMPLE FACT OF A FNT COMING THRU
WITH LINGERING INSTIBILITY AND SFC DWPNTS IN THE MID 60S TO NR 70.
WL MENTION SCT PCPN ENDING...THEN CHC AGAIN LT WITH FRNT.

UPR TROF DEEPENS OVR RGN SUN AS NEXT MAJOR UPSTREAM MID LEVEL S/W...

DRY SUN NGT INTO MON.  WL MENTION A POP ON MON OVR WRN CWA AS RETURN
FLOW/WAA MAY HELP TRIGGER PCPN THERE IN THE AFTN.
