...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS CENTRAL/NORTHERN
HIGH PLAINS TO MI...

...SUMMARY...
Isolated severe wind and hail storms are possible from the
central/northern High Plains to Michigan, mainly during the late
afternoon and evening.

...Central/northern Great Plains...
A minor mid-level impulse evident over the eastern Great Basin
should reach western SD by evening, kicked east by a shortwave
trough amplifying across the Canadian Rockies. Mid-level flow
associated with the lead impulse will be rather weak with 500-mb
winds averaging 10-15 kt at peak heating. Modest low-level upslope
flow will aid in scattered thunderstorms forming off the higher
terrain from CO into far southern MT by mid afternoon. This activity
should largely drift east towards a corridor of moderate buoyancy
(MLCAPE of 1500-2000 J/kg) centered on the MT/WY/SD border area
southeast into north-central NE. Veering of the wind profile with
height and moderate upper-level winds might support some loosely
organized clustering towards early evening. The relative best chance
for this to occur appears centered on southwest SD into northwest
NE. Isolated severe wind and hail are the most likely hazards.

...Mid-MO Valley to MI...
A narrow corridor of moderate buoyancy should develop just ahead of
a front that should decelerate across MI/WI and become
quasi-stationary to the west across northern IA into northeast NE.
Sufficient convergence along the front should exist for isolated to
scattered late afternoon to early evening thunderstorms. Modest
deep-layer shear should support locally damaging winds and
marginally severe hail prior to activity weakening by late evening.
