...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE NORTH-CENTRAL U.S....

...SUMMARY...
Isolated thunderstorms associated with severe gusts and hail will be
possible across parts of the north-central U.S. on Wednesday.

...Central and Northern Plains/Upper Mississippi Valley...
A large-scale anticyclonic flow pattern is forecast across the
central and northern U.S. on Wednesday. At the surface, a moist
airmass should be located from the Great Plains into the Mississippi
Valley. As surface temperatures warm on Wednesday, moderate
instability is expected to develop across much of the moist airmass.
Due to the anticyclonic flow pattern and lack of any shortwave
trough, large-scale ascent is forecast to remain weak over much of
the north-central U.S. In spite of this, isolated thunderstorms may
develop in areas that heat up that most, or along pre-existing
boundaries. For cells that initiate and persist, deep-layer shear
may be strong enough for an isolated severe threat. A few severe
gusts and hail will be possible, but any threat should remain
localized.
