...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FOR PARTS OF THE
NORTHERN GREAT PLAINS AND UPPER MIDWEST...

...SUMMARY...
Strong thunderstorms may impact a corridor across the northern Great
Plains into portions of the Upper Midwest late Wednesday afternoon
into Wednesday night, posing at least some risk for severe wind and
hail.

...Synopsis...
A mid/upper-level trough is forecast to move from the Great Lakes
toward New England on Wednesday, while another mid/upper-level
trough moves from the northern Rockies to the northern Plains and
eventually parts of the upper Midwest by the end of the period. A
surface low will move across the Canadian Prairies and eventually
into northern Ontario, while a secondary surface low may develop
across the western Dakotas and move northeastward into northern MN.
A warm front is forecast to lift northward across the eastern
Dakotas and western MN in advance of the surface lows, while a cold
front will begin moving across parts of the northern High Plains. 

...ND into northern MN...
A conditionally favorable environment for severe thunderstorms is
expected to develop Wednesday afternoon/evening from central/eastern
ND into northwest MN, as low-level moistening beneath steep midlevel
lapse rates supports moderate destabilization, and deep-layer shear
increases in response to the approaching mid/upper-level trough.
However, guidance continues to vary regarding placement of the
primary surface boundaries, the magnitude of low-level moistening
and destabilization, and the potential for surface-based
development.  

Confidence remains low regarding the convective evolution across
this region, but an isolated supercell or two capable of all severe
hazards will be possible during the late afternoon/early evening, if
surface-based convection can be sustained. Otherwise, some increase
in slightly elevated convection is possible later in the evening,
which would potentially pose mainly a hail and damaging wind threat.
 
...SD...northern NE...eastern WY/MT...
Widely scattered high-based thunderstorms are possible across parts
of WY into southeast MT Wednesday afternoon, which are then forecast
to spread across SD into northern NE with time. Strong
heating/mixing and increasing deep-layer shear will support
outflow-dominant clusters capable of producing severe wind gusts as
they spread east-northeastward from late afternoon into the evening.
