SPC Mar 10, 2023 Day 4-8 Severe Weather Outlook

LIVE MAP (ABOVE) ... Day 4-8 Outlook Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0333 AM CST Fri Mar 10 2023 Valid 131200Z - 181200Z ...DISCUSSION... As an upper trough encompasses much of the eastern CONUS, a surface cold front is forecast to move southward across FL on Day 4/Monday. While isolated strong convection appears possible through the day along/ahead of the front, deep-layer shear should quickly decrease with southward extent over the FL Peninsula. Accordingly, any severe threat should remain rather marginal. After this front clears the coast, severe potential is expected to be negligible across the CONUS on both Day 5/Tuesday and Day 6/Wednesday owing to a lack of appreciable low-level moisture and related instability. Although details remain uncertain, most guidance suggests that another large-scale upper trough should move eastward across the western/central CONUS during the middle to latter portion of next week. At this point, low-level moisture return ahead of this feature appears rather limited. While an isolated severe risk may ultimately evolve from Day 7/Thursday into Day 8/Friday across some part of the southern Plains into the lower MS Valley/Southeast, predictability remains far too low to include any 15% severe probabilities at this extended time frame.
