Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0334 AM CDT Thu Apr 08 2021 Valid 111200Z - 161200Z ...DISCUSSION... Medium-range models indicate a mid-level low over the southern Great Lakes will weaken on Sunday (day 4) as an attendant trough moves across the Mid-Atlantic states and Carolinas. If appreciable instability can develop over parts of the Mid-Atlantic states, some risk for strong thunderstorms could develop. This scenario is characterized by relatively high uncertainty at this time. The potential for severe thunderstorms will likely be lowest on Monday as high pressure over the northern Gulf Coast states limits destabilization. Models indicate southwesterly mid-level flow will become established across the southern High Plains downstream of a potential amplifying trough over the western U.S. Predictability is too low during the latter half of the extended period.
