Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0343 AM CST Sat Dec 02 2023 Valid 051200Z - 101200Z ...DISCUSSION... ...Tuesday/Day 4 to Thursday/Day 6... A mid-level trough is forecast to move into the mid Mississippi Valley on Tuesday, and then to the Atlantic Coast by Wednesday. An upper-level ridge is forecast to move into the central states during the mid-week.
