Day 2 Convective Outlook  
NWS Storm Prediction Center Norman OK
1136 PM CST Tue Nov 17 2020

Valid 191200Z - 201200Z


The threat for thunderstorms should be negligible on Thursday.

The large-scale flow regime will trend more zonal into Thursday as a
series of midlevel shortwave troughs progress inland over the
northern Rockies and northern Plains.  Rising heights with time over
the Pacific Northwest coast suggest that shallow convection is
unlikely to produce much if any lightning.  Some shallow, elevated
convection will be possible during the day across the northern
Plains where lingering steep lapse rates and moisture aloft could
contribute to very marginal buoyancy rooted above the surface. 
However, the threat for thunderstorms should remain too low for an
outlook area.  Elsewhere, gradual moistening in easterly low-level
flow could support a few convective showers across far south FL and
the Keys, but pronounced midlevel convective inhibition will keep
the convection too shallow/warm for charge separation.
