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

....SUMMARY...
Severe thunderstorms are not forecast on Saturday.

....Synopsis...

A pair of upper shortwave troughs will migrate across the northern
Plains and Upper Midwest on Saturday, maintaining broad upper
troughing across much of the central U.S. Late in the period,
another upper shortwave trough will approach the Pacific Northwest.
Overall, severe potential is expected to remain limited due to poor
lapse rates and weak vertical shear. Nevertheless, upper 50s to mid
60s F dewpoints across portions of the Plains to the MS Valley will
support scattered diurnal thunderstorm activity.
