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

....SUMMARY...
Severe thunderstorm potential is low on Wednesday.

....Synopsis...

A positive-tilt upper shortwave trough over the northern/central
High Plains Wednesday morning will meander eastward as a pair of
upper lows develop in the vicinity of NE and eastern MT. Deep-layer
flow is expected to remain weak over the Plains, limiting vertical
shear. However, upper 50s to mid 60s F dewpoints ahead of a
weakening/stalled surface front will remain over eastern portions of
the Great Plains into the Mid-MO Valley. This will support pockets
of weak to moderate destabilization where stronger heating occurs.
Morning clouds and ongoing showers/thunderstorms could be in place
across portions of the Plains Wednesday morning, resulting in
uncertainty in where better destabilization may occur. Isolated to
scattered thunderstorms appear likely across parts of OK/KS
northward through the Mid-MO Valley vicinity. However, nebulous
forcing and weak shear are likely to limit severe potential.
