Concerning...Severe Thunderstorm Watch 102...

Valid 132209Z - 132345Z

The severe weather threat for Severe Thunderstorm Watch 102
continues.

SUMMARY...A multicell cluster of storms may produce occasional wind
damage into early evening. Local extension in area of WW 102 is
possible, but additional watches are not expected.

DISCUSSION...A cluster of multicell storms continues east near the Indiana/Michigan border. Recent observations show max convective
gusts in the low 40 kt range. Water vapor imagery shows modest
shortwave ridging over this area which has lead to marginal
effective shear values. Downstream of this activity, dewpoints have
mixed down into the upper 50s F. The current expectation is for this
cluster to continue to produce occasional damaging winds with a
general decrease in intensity/organization with time. The strongest
activity may remain on the southern flank where dewpoints are
slightly higher. While local extensions of WW 102 may occur,
additional watches are not expected at this time.
