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

....SUMMARY...
The potential for severe storms appears to be low across the
continental U.S. on Wednesday. A few stronger storms cannot be ruled
out over parts of Minnesota and Wisconsin late in the day, and over
eastern Colorado.

....Synopsis and Discussion...
An upper trough will exit the Mid Atlantic/Northeast on Wednesday
with a secondary wave developing later in the period into the Upper
and Middle MS Valley and Great Lakes. Behind the initial trough,
high pressure will already be in place over the OH Valley, which
will limit destabilization ahead of the secondary system. However, a
narrow plume of low-level moisture with 50s F dewpoints will result
in a marginally unstable environment across the upper MS Valley by
late afternoon. Cool temperatures aloft and modest deep-layer shear
of 20-30 kt may result in a few cells capable of mainly
small/non-severe hail.

Southwest of this region, east/southeast surface winds will persist
over the central plains, as a weak surface trough develops over
eastern CO. The moist easterly flow toward the Front Range may
result in a few stronger cells, perhaps with hail potential. Lapse
rates aloft will not be very steep beneath the weak upper ridge, nor
will shear be very favorable. However, at least small hail may occur
locally during the late afternoon for a short time near peak
heating.
