CONCERNING...SEVERE THUNDERSTORM WATCH 505...

VALID 210015Z - 210115Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 505
CONTINUES.

SUMMARY...THE RISK FOR SVR TSTMS CONTINUES ACROSS REMAINING VALID
PORTIONS OF WW 505...AND THE RISK FOR STRONG TSTMS MAY EXTEND
FARTHER S.

DISCUSSION...BANDS OF OCCASIONALLY BOWING CONVECTION AT THE LEADING
EDGE OF A STRATIFORM RAIN SHIELD CROSSING SERN LOWER MI AND NWRN OH
MAY SUPPORT A DMGG-WIND RISK IN THE NEXT COUPLE OF HOURS AS THE FLOW
ALOFT REMAINS MODERATE. HOWEVER...RADAR TRENDS SUGGEST A PROPENSITY
FOR CONVECTION TO BECOME INCREASINGLY DISORGANIZED AS IT ENCOUNTERS
A RELATIVELY DRIER/LESS UNSTABLE BOUNDARY LAYER...WITH THE SVR-TSTM
RISK LIKELY LESSENING AS THE STORMS SHIFT EWD ACROSS REMAINING VALID
PORTIONS OF WW 505. A FEW STRONG STORMS MAY ALSO ADVANCE FROM
E-CNTRL INDIANA TO W-CNTRL OH WITH A RISK FOR STRONG WIND GUSTS.
