Areas affected...South-Central/Southeast MN...West-Central WI

Concerning...Severe Thunderstorm Watch 542...

Valid 270546Z - 270715Z

The severe weather threat for Severe Thunderstorm Watch 542
continues.

SUMMARY...Ongoing storms are expected to persist for the next hour
or two with an isolated strong wind gust and hail threat. Spatial
and temporally limited threat will preclude the need for another
watch downstream.

DISCUSSION...Thunderstorms continue along a weak cold front
extending from western Lake Superior southwestward through
west-central WI and south-central MN. Strongest storm is currently
moving through Dunn and eastern Pepin counties in west-central WI.
Storms have also recently intensified farther southwest along the
front in southeast and south-central MN.

Given the strong convective inhibition (i.e. -200 J/kg) in place for
any surface-based parcels, these ongoing storms are likely elevated,
supported by weak warm-air advection between 925 and 850 mb.
Moderate instability exists downstream, supported by lapse rates
between 800 and 600 mb near 7 deg C per km and ample low-level
moisture (100-mb mean mixing ratios around 14 g/kg). Moderate
vertical shear also exists, with mesoanalysis estimating effective
bulk shear around 35-40 kt. Expectation is for the ongoing storms to
persist for the next hour or two before eventually weakening as the
warm-air advection weakens. Before they weaken, a few strong wind
gusts and isolated hail are possible. Spatial and temporally limited
threat will limit the need for a downstream watch.
