Valid 120100Z - 121200Z

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE UPPER
MIDWEST AND MID MISSOURI VALLEY REGION...

...SUMMARY...
Severe thunderstorms remain possible through late evening across the
Upper Midwest and Middle Missouri Valley. The primary risks are hail
and wind.

...Upper Midwest/Middle Missouri Valley...

Leading edge of stronger large-scale forcing for ascent is spreading
across MN/western IA/eastern NE. Convection is increasing along the
frontal zone in response to this forcing with several line segments
now evident from western MN into eastern NE. 00z soundings ahead of
the front (MPX, OAX, TOP) exhibit substantial inhibition, thus
robust convection should hold close to the surging cold front.
Damaging winds and some hail can be expected as the frontal squall
line progresses eastward this evening. Have adjusted severe
probabilities down along the cool side of the boundary.
