Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0237 AM CST Tue Jan 12 2021 Valid 151200Z - 201200Z ...DISCUSSION... Model consensus is that a large upper trough will be centered over the Midwest by early day 4 (Friday), and this feature will move slowly east, finally exiting the eastern seaboard late day 5 (Saturday). Offshore flow and stable conditions inland will prevail during this time. A lower-amplitude, more progressive shortwave trough is forecast to move through the central and eastern U.S. day 6-7 on the heels of the previous trough. However, the speed of this feature and lack of cyclogenesis suggest there will not be sufficient moisture return for a severe threat.
