Areas affected...South-central Minnesota

Concerning...Tornado Watch 103...

Valid 132302Z - 140030Z

The severe weather threat for Tornado Watch 103 continues.

SUMMARY...With several discrete storms near the warm front, areas of south-central Minnesota will see an increase in tornado and
very-large hail potential this evening.

DISCUSSION...Storms have maintained a discrete mode in southern
Minnesota late this afternoon. This environment has steeper
mid-level lapse rates than farther east and is more closely tied to
a subtle shortwave trough in water vapor imagery. Given the expected
increase in low-level shear this evening, this area will become more
favorable for tornadoes and very-large hail over the next 2-3 hours
so long as a discrete storm mode can be maintained. Current VAD
observations from KFSD and KARX already show large low-level
hodographs that should improve over time.
