Concerning...Severe Thunderstorm Watch 415...
Valid 300426Z - 300630Z
The severe weather threat for Severe Thunderstorm Watch 415
continues.
SUMMARY...Isolated severe wind gusts remain possible primarily near
the ND/SD border, south of JMS, into west-central MN.
DISCUSSION...Earlier high-based convection that developed along the
pre-frontal surface trough has weakened considerably as it
progressed into southwest MN. While gusty winds remain possible with
the weakening convection, most of this activity should remain sub
severe. However, thunderstorms that developed immediately ahead of
the short-wave trough along the front have tracked along the ND/SD
border and a loosely organized cluster is currently noted just south
of JMS. This activity is expected to progress east along a boundary
that is draped across this region into west-central MN over the next
few hours. Latest diagnostic data suggest the greatest buoyancy
resides along/north of this boundary which should result in a
greater concentration of storms across the northern portions of
ww415.
