Areas affected...northeastern Minnesota

Concerning...Severe Thunderstorm Watch 525...

Valid 290200Z - 290330Z

The severe weather threat for Severe Thunderstorm Watch 525
continues.

SUMMARY...Scattered stronger cells within a larger cluster of storms
still pose some risk for severe hail and wind, but probably will
begin to weaken as they spread toward the Minnesota Arrowhead
through 10-11 PM CDT.

DISCUSSION...Scattered stronger storms have been maintained within
the initial clustering of storms which has spread east-northeast of
the Bemidji vicinity the past couple of hours.  This activity has
been supported by favorable large-scale forcing for ascent,
associated with a focused area of mid-level warm advection, beneath
the divergent upper flow field near the exit region of a 50-70 kt
jet core at 300 mb.  As storms continue eastward, inflow appears
likely to increasingly emanate from cooler, stable air influenced by
Lake Superior within the next hour or two.  This probably will
result in diminishing severe potential, with stronger storm
development continuing to beco*e focused along the warm frontal
zone, near and west through north of the Greater Minneapolis-St.
Paul area.
