Day 2 Convective Outlook  
NWS Storm Prediction Center Norman OK
1230 PM CDT Fri Sep 13 2024

Valid 141200Z - 151200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Organized severe thunderstorms are not forecast on Saturday.

...North-Central High Plains including parts of NE/SD...
A north/south-oriented boundary will be in place Saturday afternoon
and evening across the north-central High Plains, spanning northeast
Colorado and western Nebraska into the western Dakotas. Influenced
by stronger westerlies centered over the Pacific Northwest,
semi-cool mid-level temperatures and relatively steep lapse rates
will coincide with 50s F surface dewpoints near/east of the surface
trough/boundary, leading to 1000+ J/kg MLCAPE by mid-afternoon. At
least widely scattered thunderstorms are expected to develop by
mid/late afternoon. Effective shear of 25-30 kt could support some
multicellular storm sustenance. A few of these storms could produce
marginally severe hail and/or strong wind gusts, although some
spatial/intensity details very in guidance. Subsequent outlooks into
the Day 1 time frame will reevaluate for the potential introduction
of severe probabilities.

...Southeast...
The remnants of Post-Tropical Cyclone Francine will continue to
weaken and remain nearly stationary across the Lower Mississippi
Valley on Saturday. At least modest buoyancy should be displaced
well to its southeast across Florida and the coastal Southeast
Saturday afternoon, well away from the Tennessee Valley. The overall
potential for organized severe storms appears low.
