Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0304 AM CST Thu Feb 04 2021 Valid 071200Z - 121200Z ...DISCUSSION... Broad upper trough is expected to persist into the middle of next week as a series of shortwave troughs continued to reinforce the prevailing pattern. Additionally, a cold, polar air mass is expected to move into the northern/central Plains and Upper Midwest on D4/Sunday before continuing southward/southeastward into the southern Plains and MS and OH Valleys on D5/Monday. High surface pressure associated with this cold air mass will then dominate sensible weather across the majority of the CONUS for the remainder of the period. The only exception is across FL, where a few thunderstorms are possible on late D5/Monday into early D6/Tuesday as a shortwave trough glances the region.
