Areas affected...Portions of eastern Illinois into central/northern
Indiana and southwest Lower Michigan
Concerning...Tornado Watch 70...71...
Valid 301905Z - 302100Z
The severe weather threat for Tornado Watch 70, 71 continues.
SUMMARY...There is an increasing risk for severe wind gusts in
central/northern Indiana and southern Lower Michigan.
DISCUSSION...An organized line of storms continues to move northeast
in parts of eastern Illinois. Several measured and estimated severe
gusts occurred in the Champaign, IL vicinity recently. KILX radar
shows strong outbound winds within this line. With continued surface
heating of mostly clear/partly cloudy skies in Indiana and forcing
from the shortwave trough, the potential for severe wind gusts
should continue through the afternoon. Low-level shear is not overly
strong per downstream VAD data, but QLCS tornadoes remain possible.
The greatest potential for a tornado (and large hail) would likely
exist on the southern flank of the line where storms may remain more
discrete.
