IN SATELLITE IMAGERY. WV LOOP SHOWS VORT DROPPING INTO BASE OF UPR TROF
AND IS NOW IN NW MO. WEAK MCS INDUCED IMPULSE MVG TO THE NE ALG FNT IN
SRN IL BUT IS WEAKENING/DAMPENING OUT WITH TIME. HOWEVER..UPR SPD MAX
THAT IT GENERATED (85 KT) WILL AID IN CNVTV DEVELOPMENT. THESE FACTORS
WILL ENHANCE CNVTN ACRS NE KY..SE OH AND WRN PA. TRENDS IN GOES DERIVED
CINH SHOWS CAP HAS QUICKLY ERODED WITH MOST OF TH AREA NOW AOB 30 J/KG.
.
MOISTURE CONSIDERATIONS ARE ADEQUATE TO SUPPORT HEAVY RAIN BUT NOT EYE
POPPING. GOES DERIVED PW/S RUNNING ARND 1.7" WITH SFC TD/S WITHIN A
FEW DEGREES OF 70F. SFC MOISTURE CONVERGENCE FIELD SHOWS BROAD..NOT
FOCUSED..AREA OF CONVERGENCE FROM CENTRAL OH INTO CENTRAL/WRN KY
ATTM. SEVERAL DISJOINTED AREAS OF CNVTN ARE DEVELOPING ATTM – W CENTRAL
OH..ALG THE LAKE BREEZE IN NE OH/NW PA..E OF KCVG AND IN EXTRM SE IN. ALL
OF THESE AREAS ARE PROGRESSIVE BUT AREAS OF MOST CONCERN FOR HEAVY RAIN
