Areas affected...portions of northern into central Minnesota

Concerning...Severe Thunderstorm Watch 409...

Valid 250350Z - 250545Z

The severe weather threat for Severe Thunderstorm Watch 409
continues.

SUMMARY...The risk for severe winds is expected to persist for the
next few hours across northern into central Minnesota in association
with a well-developed thunderstorm squall line. A 75+ mph gust
remains possible in the near term.

DISCUSSION...An organized bow-echo MCS has beco*e established across
northwest MN with a history severe wind gusts, with 1-2 gusts near
or exceeding 75 mph. The MCS continues to progress east-southeast
amid a moderately unstable airmass, characterized by 2000-2500 J/kg
MLCAPE. The onset of nocturnal cooling and increase in CINH should
contribute to a gradual weakening of the bow echo later tonight,
especially since deep-layer shear and lift remain modest. In the
meantime, at least isolated severe gusts should continue with the
bow echo over the next few hours and an additional 75+ mph wind gust
cannot be co*pletely ruled out.
