...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM
SOUTHEASTERN MINNESOTA AND SOUTHWESTERN WISCONSIN SOUTH TO NORTHERN
MISSOURI...
CORRECTED TO ADD LESS THAN 2% LABEL TO TORNADO GRAPHIC
...SUMMARY...
A couple of instances of large hail and/or strong gusts remain
possible through mid evening acros portions of the Middle
Mississippi Valley.
...Discussion...
Thunderstorms continue to swirl around an upper low drifting
southward across southwestern Minnesota toward northwestern Iowa
this evening. The strongest storms are ongoing over eastern Iowa
and into adjacent southwestern Wisconsin/northwestern Illinois, near
an axis of moderate instability (1500 to 2500 J/kg mixed-layer CAPE)
just ahead of the surface cold front.
As the boundary layer continues to gradually cool diurnally, storm
intensity will gradually decrease. In the mean time however, a few
stronger storms will continue to pose risk for marginal hail and/or
strong wind gusts.
