Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0319 AM CST Thu Nov 12 2020 Valid 151200Z - 201200Z ...DISCUSSION... 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.
