Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0340 AM CST Thu Jan 09 2025 Valid 121200Z - 171200Z ...DISCUSSION... A northwest mid-level flow pattern is forecast to remain in place over the central U.S. throughout the Day 4 to 8 period, as a series of shortwave troughs move southeastward through the flow. The northwesterly flow will help to drive multiple fronts southward into the central and eastern U.S, which will keep a relatively cold and dry airmass in place. For this reason, conditions are not expected to be favorable for thunderstorm development across the continental U.S. through the middle of next week.
