Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0328 AM CDT Fri Oct 23 2020 Valid 261200Z - 311200Z ...DISCUSSION... A positive-tilt large-scale trough over the western U.S. on Monday will likely evolve into a closed mid-level low and meander eastward into the southern Great Plains by the Wednesday-Thursday (day 6-7) timeframe. Medium-range model guidance varies on the timing/placement of mid-level low and subsequent surface reflection over the lower MS Valley. Given the model predictability concerns during the latter half of the extended period, a predictability-too-low highlight will be maintained. If strong storms develop during the late Wednesday through Friday period next week, the potential at this point would focus over the lower MS Valley and central Gulf Coast.
