Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0156 AM CST Fri Jan 08 2021 Valid 111200Z - 161200Z ...DISCUSSION... A weakening shortwave trough will move from TX across the Southeast during the Monday/D4 to Tuesday/D5 period, with a weak surface low moving from the northern Gulf Coast at 12Z Monday/D4 to just off the Outer Banks of NC by 00Z Wednesday/D6. Given the cool/dry air mass in place ahead of this system, little if any surface-based instability is forecast to develop. For the remainder of the period Wednesday/D6 to Friday/D8, models show a stable pattern will continue with several days of offshore flow across the Gulf of Mexico and East Coast. While models disagree on whether there will be a closed upper low or a large upper trough over the eastern CONUS, very low heights and strong northwest flow over the Plains will aid in prolonging the cool and stable pattern.
