Areas affected...much of central Minnesota

Concerning...Severe Thunderstorm Watch 607...

Valid 210046Z - 210215Z

The severe weather threat for Severe Thunderstorm Watch 607
continues.

SUMMARY...Severe hail remains a concern with the stronger sustained
supercells this evening.

DISCUSSION...Multiple sustained supercells have progressed across
central MN over the past few hours, with marginally severe hail
reported (particularly with the storms over northern MN). 2000-3000
J/kg MLCAPE remains in place, along with 35-40 kts of effective bulk
shear per 00Z mesoanalysis. The 00Z MPX observed sounding also shows
a hodograph with appreciable low-level curvature and modest
elongation, suggesting that supercells will remain the dominant mode
of the convection through the evening hours. Large hail should
remain the primary threat, though a damaging gust or tornado cannot
be ruled out.
