Day 1 Convective Outlook  
NWS Storm Prediction Center Norman OK
0757 AM CDT Sat Oct 17 2020

Valid 171300Z - 181200Z


Severe thunderstorms are not expected across the contiguous United
States through tonight.

While severe thunderstorms are not expected, thunderstorms will be
possible today/tonight in two regional areas as large-scale
troughing generally prevails over the CONUS through tonight. A
relatively moist air mass will linger across the southern Florida
Peninsula today. Moist profiles and poor lapse rates are suggestive
of mostly weak convection with occasional lightning. Elsewhere, some
moistening will occur across the Ozarks/Mid-South tonight with aid
of an increasing low-level jet, with isolated/widely scattered
convection expected to develop across the region late tonight/early
Sunday. Instability is expected to be too weak for any meaningful
risk of elevated severe storms.
