...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM NEBRASKA
INTO PARTS OF IOWA AND NORTHERN MISSOURI...

...SUMMARY...
A corridor of damaging winds may develop Saturday afternoon and
evening from Nebraska into Iowa/Northern Missouri.

...Mid to Lower MO Valley...
Moderate northwest flow aloft will persist across the northern
Plains into the Great Lakes on Saturday, as the main upper wave
rotates northeast from Ontario into Quebec. The southern periphery
of this stronger flow aloft will remain over the middle to lower MO
Valley, with a warm front developing across NE and IA. Strong
heating will occur east of a surface low either in western NE or KS,
with south winds resulting in a deep mixed layer by afternoon.

Storms are expected to form over NE, and possibly move into IA or MO
through evening in the form of an MCS. This would be fueled by a
strengthening southerly low-level jet as well, suggesting an
organized system may occur. For now, low probabilities have been
added due to uncertainty with placement of any such corridor.
Damaging winds would be the main concern.

...Mid Atlantic...
Scattered afternoon storms will again be likely over much of the
eastern states on Saturday, within a modest southwest flow regime. A
high PW environment will remain in place, supporting an uncapped air
mass and conditional/localized wind risk. Predictability is low at
this time given possible antecedent rain or thunderstorm areas, but
low probabilities for wind could be added in later updates.
