Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0352 AM CDT Thu Oct 15 2020 Valid 181200Z - 231200Z ...DISCUSSION... An upper trough embedded within the mid-level westerlies is forecast to move from the north-central states into the Northeast and Canada on Day 4/Sunday. Although low-level moisture return may occur to the south of this feature across the southern Plains vicinity, the potential for organized severe storms appears low. Medium-range guidance has come into somewhat better agreement regarding the evolution of the mid/upper-level jet across the northern/central CONUS in the early to middle portion of next week. Still, differences remain in both the northward extent and quality of the low-level moisture return across the central CONUS. Some guidance suggests potential for isolated severe storms across parts of the southern/central Plains into the mid MS Valley and perhaps the Midwest from Day 5/Monday into at least the middle of next week. However, too much uncertainty exists regarding this severe potential to include any probabilities at this time.
