I'm seeing some rather impressive ctg where I'm at. Very heavy rain and it's not moving too fast. Just what we need after last week. Surprised that NWS hasn't put out a statement yet.

Worst electrical storm of the year going on right here right now. Hardly any rain but ctg lightning is constant.

Surprised I still have power.

PROBABILITY OF WATCH ISSUANCE...60 PERCENT

SUMMARY...THE ISSUANCE OF A SVR TSTM WATCH IS POSSIBLE THIS
AFTERNOON IF STORMS TREND TOWARD CONSOLIDATION AND GREATER UPSCALE
GROWTH. OTHERWISE...THE STRONGER...SUSTAINED UPDRAFTS WILL BE
CAPABLE OF PRODUCING A THREAT FOR MAINLY HAIL AND STRONG WIND GUSTS.

DISCUSSION...MID AFTERNOON MOSAIC RADAR IMAGERY SHOWED A BROKEN BAND
OF TSTMS...A FEW BECOMING STRONGER TO SEVERE AT TIMES...ALONG THE
LEADING EDGE OF A MODESTLY ORGANIZED CONVECTIVE SYSTEM PROGRESSING
ESEWD THROUGH ERN OH AND WRN PA. ALTHOUGH IR SATELLITE IMAGERY DID
NOT INDICATE RAPID COOLING WITH THESE STORMS AND WDSS-II 9 KM CAPPI
IMAGERY SHOWED ONLY A FEW SUSTAINED/STRONGER UPDRAFTS IN CENTRAL/ERN
OH...A RATHER MOIST AND MODERATELY UNSTABLE AIR MASS HAS DEVELOPED
ALONG AND AHEAD OF THE CURRENT STORMS. FORCING FOR ASCENT ATTENDANT
TO A PROGRESSIVE MCV...NOW MOVING INTO NERN OH...PER RADAR IMAGERY
MAY CONTINUE TO PROVIDE SUPPORT FOR ADDITIONAL STORMS...IN ADDITION
TO ASCENT/LIFT ALONG THE LEADING EDGE OF THE MCS INTO THE MODERATELY
UNSTABLE AIR MASS. EFFECTIVE BULK SHEAR UP TO 35-40 KT IS MORE THAN
SUFFICIENT FOR ADDITIONAL STORM ORGANIZATION WITH THE SUPERCELLS AND
BOWING SEGMENTS POSSIBLE.
