Day 4-8 Convective Outlook  
NWS Storm Prediction Center Norman OK
0319 AM CST Thu Nov 12 2020

Valid 151200Z - 201200Z

An amplified yet progressive large-scale pattern will exist late
this weekend through much of next week based on latest-available
guidance. On Day 4/Sunday, an upper trough is likely to continue an
east-northeastward transition over the Great Lakes/Northeast States
and Ontario/Quebec. Some thunderstorms will be possible across the
eastern third of the CONUS. While a few strong fast-moving storms
could occur, organized severe thunderstorms do not appear overly
likely at this juncture. Pre-cold-frontal moisture/buoyancy will
tend to be very limited in conjunction for the more appreciable
forcing for ascent and stronger shear.

Thereafter, the severe-weather risk should be very low through the
early/middle part of next week including Days 5-8. Appreciable
low-level moisture will be shunted southward across the Gulf of
Mexico/Florida Straits with a cold front, with high pressure and
stable conditions otherwise prevailing east of the Rockies.
