Areas affected...central and eastern Michigan
Concerning...Severe Thunderstorm Watch 121...
Valid 171837Z - 172000Z
The severe weather threat for Severe Thunderstorm Watch 121
continues.
SUMMARY...A large hail and damaging wind threat persists across
eastern Michigan.
DISCUSSION...A broken line of storms continues to move east across
Lower Michigan. Only a few damaging wind gust reports have been
received thus far with measured gusts of 28 and 35 knots at KLAN and
KJXN as the line moved through. Therefore, the majority of this line
is likely producing sub-severe wind gusts with occasional severe or
near severe wind gusts possible, particularly with any mesovorticies
within the line. Otherwise, the only large hail was reported from
the supercell which developed ahead of the line and moved through
the south side of Lansing. The window for additional supercell
development ahead of the line is closing as the line moves into
increasingly stable air across eastern Michigan with a somewhat Lake
Erie modified airmass. However, stronger cores may be possible
across far southeast Michigan where greater instability is present.
