Day 1 Convective Outlook  
NWS Storm Prediction Center Norman OK
1030 AM CST Sun Jan 17 2021

Valid 171630Z - 181200Z

...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are not expected across the contiguous U.S. through
tonight.

...Synopsis/Discussion...
The potential for lightning-producing convection will be essentially
nil across the CONUS this afternoon and tonight. Associated with an
advancing shortwave trough, a couple of lightning flashes cannot be
conclusively ruled out this afternoon amid steep lapse rates across
the middle Ohio Valley and Cumberland Plateau, however this
potential should remain very low given the very shallow nature of
the convection.
