Areas affected...the Western U.P. of Michigan

Concerning...Severe potential...Watch possible=20

Valid 292024Z - 292230Z

Probability of Watch Issuance...60 percent

SUMMARY...The potential for at least isolated occurrences of severe
wind gusts is expected to increase in the 2100-2130Z (4:00-4:30 PM
CDT) time frame. A severe thunderstorm watch is possible.

DISCUSSION...As of 2020Z, a long-lived bowing MCS was progressing
through far western Lake Superior at around 45 kt. Extrapolation of
the current motion takes it into the western U.P. of MI and adjacent
near-shore waters between 2100-2130Z. The MCS is located to the
north of a warm front lifting north through northern WI, suggesting
that it might be slightly elevated atop a shallow near-ground
inversion. Nonetheless, the presence of a strong rear-inflow jet
will support the potential for at least isolated severe wind gusts
late this afternoon into early evening.
