Day 1 Convective Outlook

1016 AM CST Tue Dec 22 2020

Valid 221630Z - 231200Z


Thunderstorms are not expected through tonight.

Relatively dry and stable conditions are expected to preclude
organized thunderstorms across the CONUS today.  An isolated
lightning flash or two is possible in the Black Hills vicinity this
afternoon and evening as a strong shortwave trough approaches.  This
activity should be very sparse, and may not reach sufficient depth
for charge separation.
