Day 2 Convective Outlook  
NWS Storm Prediction Center Norman OK
1226 AM CDT Fri Oct 23 2020

Valid 241200Z - 251200Z


Severe thunderstorms are not forecast across the contiguous U.S. on

Broad cyclonic mid-level flow will encompass much of the northern
tier of states on Saturday.  A cold front will push eastward across
the Northeast.  The trailing portion of the front will weaken during
the period as it moves southeast across the southern Appalachians
and lower MS Valley.  Farther west, surface cyclogenesis will occur
in the central High Plains during the day, and the trailing portion
of the front over the lower MS Valley will advance northward as a
warm front over the southern Great Plains.  A cold front will push
southward over the central High Plains during the evening/overnight.
Scattered showers and isolated thunderstorms are possible from the
northeast Gulf Coast into the southern Appalachians/VA during the
day.  Relatively weak large-scale forcing and limited instability
will likely preclude strong thunderstorms from developing.  The
shower/thunderstorm activity will diminish by the early evening
