Areas affected...Minnesota region

Concerning...Severe Thunderstorm Watch 578...

Valid 090425Z - 090630Z

The severe weather threat for Severe Thunderstorm Watch 578
continues.

SUMMARY...Convection should gradually increase along the surface
front across ww578.

DISCUSSION...Weak mid-level height falls are expected across the
upper MS Valley into the early-morning hours, immediately ahead of
progressive northern Plains upper trough. Leading edge of
large-scale forcing appear to be approaching this region where
thunderstorms have struggled a bit over the last few hours. Latest
radar data suggests convection continues along the surface front
from Kandiyohi-Crow Wing County, and some upward increase remains
possible in response to the approaching trough. Forecast soundings
suggest 700mb temperatures should cool a few degrees which supports
a gradual increase in storms along the frontal zone.
