Areas affected...Parts of southern MN and northern IA
Concerning...Severe potential...Watch possible=20
Valid 131828Z - 132030Z
Probability of Watch Issuance...40 percent
SUMMARY...Severe-storm risk will continue increasing this afternoon.
A watch issuance is possible.
DISCUSSION...Temperatures are quickly climbing into the lower/middle
80s amid upper 60s boundary-layer dewpoints across parts of southern
MN and northern IA -- where a weak low-level confluence zone is
evident. As ascent accompanying a subtle midlevel impulse (evident
in water vapor imagery) crosses the area, an increase in storm
coverage is possible. A unidirectional wind profile characterized by
30-40 kt of effective shear over the area, coupled with continued
diurnal destabilization, should support a few organized clusters and
perhaps supercell structures capable of large hail and locally
damaging winds. Trends are being monitored for a possible watch
issuance.
