Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0208 AM CDT Mon Sep 28 2020 Valid 011200Z - 061200Z ...DISCUSSION... A series of shortwave troughs are forecast to rotate through the broad upper troughing expected to persist across the central and eastern CONUS through the weekend. Stable continental air accompanying these shortwaves will help reinforce the continental air mass already expected to be in place. At the same time, upper ridging is expected to remain in place across the western CONUS. This relatively stagnant upper pattern is not favorable for thunderstorms across the majority of the CONUS. The only exception is across central and southern FL where more low-level moisture will likely persist.
