Mesoscale Discussion 2012
NWS Storm Prediction Center Norman OK
0557 AM CDT Tue Aug 27 2024
Areas affected...eastern Minnesota and western Wisconsin
Concerning...Severe potential...Watch unlikely
Valid 271057Z - 271230Z
Probability of Watch Issuance...20 percent
SUMMARY...A locally greater severe wind threat will persist across
eastern Minnesota and western Wisconsin for a few hours this
morning.
DISCUSSION...A line of mostly sub-severe storms moved across
Minnesota this morning. On the southern extent of this line, a more
organized severe wind threat developed with measured wind gusts of
50 to 60 knots in portions of the Minneapolis/St. Paul metro area
after several hours of minimal evidence of severe winds prior. The
environment across western Wisconsin is somewhat cooler, upper 60s
vs lower 70s temperatures. This may weaken this portion of the line
as it moves east. However, it is also possible that this southern
extent of the main line remains anchored to the instability gradient
and access to more favorable theta-e and is able to produce
additional isolated severe wind through the morning across western
Wisconsin. A watch is not anticipated due to the confined nature of
the threat at this time.
