Day 2 Convective Outlook  
NWS Storm Prediction Center Norman OK
1201 PM CDT Fri Oct 16 2020

Valid 171200Z - 181200Z


Severe thunderstorms are not expected across the contiguous United
States on Saturday.

...Synopsis and Discussion...
A large upper trough will remain over the central U.S. with a broad
cyclonic jet extending from the northern Rockies to the Great Lakes.

A leading shortwave trough will move across the Northeast, with high
pressure over the Mid Atlantic. This will continue to provide
relatively stable conditions over the region.

Low-level moisture will be most plentiful across south Florida,
across the Gulf of Mexico and into eastern Texas with flow around
the surface high. A few showers and storms will occur during the day
over Florida, but the southern Plains will mainly be capped. An
exception may be overnight into northeast Arkansas and vicinity,
where southwest 850 mb winds around 40 kt will support theta-e
advection, lift, and perhaps sufficient elevated instability for a
few lightning strikes.
