Valid 151200Z - 161200Z

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

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

....Synopsis and Discussion...
On Wednesday, a deep upper low will exit the Northeast with an upper
ridge progressing east across the MS Valley. Meanwhile, a lengthy
positive-tilt upper trough will move across the Rockies, reaching
the High Plains by 12Z Thursday.

Behind the eastern trough, a surface high will provide cool and
stable conditions to the eastern half of the CONUS. Low-level
moisture will return into the southern Plains overnight, as low
pressure develops over the central Plains in response to the western
trough. Dewpoints above 60 F are expected as far north as central TX
by 12Z Thursday, with 50s F dewpoints as far north as the surface
low in southern KS ahead of a cold front.

While the air mass over the Plains will remain capped for
surface-based parcels, weak elevated instability may develop into
early Thursday morning over OK, southern KS, AR, and northern TX.
Any activity is expected to be isolated, as large-scale ascent only
begins to increase late in the period, and capping even for elevated
parcels remains a possibility. Weak instability overall will
preclude severe probabilities.
