Areas affected...Central MN

Concerning...Severe Thunderstorm Watch 457...

Valid 102001Z - 102130Z

The severe weather threat for Severe Thunderstorm Watch 457
continues.

SUMMARY...Hail remains possible with the elevated thunderstorm
ongoing over central MN.

DISCUSSION...Thunderstorm cluster initially over far southeast ND
and far west-central MN moved southeastward during the past hour,
with the storms along its western periphery dissipating. Those
storms within the central and eastern portions of the cluster have
persisted, although overall updraft intensity has fluctuated.
Diurnal heating has been tempered by the abundant cloudiness within
the downstream air mass. Some destabilization has occurred as a
result of low-level moist advection, but not to the extent as
previously anticipated. As such, these storms remain elevated.

Some hail remains possible, particularly east of the ongoing watch
where the strongest updrafts are now located. However, uncertainty
regarding convective evolution (storm longevity in particular)
currently precludes watch issuance in these areas.
