Areas affected...northeast MN
Concerning...Severe Thunderstorm Watch 432...
Valid 181103Z - 181230Z
The severe weather threat for Severe Thunderstorm Watch 432
continues.
SUMMARY...Strong thunderstorm gusts of 45-60 mph remain possible
across portions of northeast Minnesota the next couple of hours.
DISCUSSION...An organized line of thunderstorms will continue
shifting east across northeast MN the next couple of hours. Measured
gusts have mostly been in the 45-60 mph range over the past hour.
Moderate elevated instability amid strong vertical shear should
maintain thunderstorm intensity for another 1-2 hours. With eastward
extent, this activity may weaken as it approaches the MN
Arrowhead/Lake Superior where temperatures are cooler and an earlier
cluster of thunderstorms has likely modified the airmass, resulting
in weaker instability.
