....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Isolated thunderstorms will be possible this evening into the
overnight across parts of the northwestern Great Lakes. Isolated
storms may also develop this evening in parts of the northern Plains
and central High Plains.

....DISCUSSION...
The latest water vapor imagery shows a trough from the northern
Plains extending southward into the central High Plains, with a
plume of mid-level moisture extending from the central Rockies into
the mid to upper Mississippi Valley and Great Lakes. Isolated
thunderstorm development will be possible this evening near the
trough, mainly in northeastern Colorado near the right entrance
region of a mid-level jet. Additional storms may form just ahead of
the trough from eastern South Dakota into western Minnesota where a
pocket of steep mid-level lapse rates is present according to
mesoanalysis data. Isolated to scattered thunderstorms will be
possible this evening into tonight further ahead of the trough near
the axis of a low-level jet in parts of the northwestern Great
Lakes. No severe threat is expected.
