Day 1 Convective Outlook  
NWS Storm Prediction Center Norman OK
0648 AM CST Thu Feb 04 2021

Valid 041300Z - 051200Z


A few thunderstorms are possible today across parts of Missouri.

A midlevel shortwave trough over the central Plains this morning
will progress eastward to the middle MS Valley by this evening and
the OH Valley overnight.  A lingering plume of steep midlevel lapse
rates precedes the midlevel trough, with sufficient midlevel
moisture for very weak buoyancy (MUCAPE 100-200 J/kg, rooted near or
above the 700 mb level).  Per recent observations, isolated
lightning flashes will remain possible today with midlevel
convection in the zone of ascent, prior to the threat diminishing
later this afternoon.
