SPC Jun 4, 2022 Day 4-8 Severe Weather Outlook

Day 4-8 Outlook Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0326 AM CDT Sat Jun 04 2022 Valid 071200Z - 121200Z ...DISCUSSION... Quasi-zonal mid/upper flow will persist through at least Day 5/Wed. Weak shortwave impulses will migrate through westerly flow atop a moist and unstable airmass across portions of the central Plains toward the mid-MS Valley. Southerly low-level upslope flow will support daily thunderstorm development across the central High Plains and some potential for overnight MCS activity tracking across the central Plains toward the mid-MS Valley will continue. By Day 6/Thu or Day 7/Fri, deterministic and ensemble guidance suggest upper level flow will amplify, with stronger northwesterly flow developing over the Plains and Midwest as a deepening trough develops over the mid-MS and OH Valley vicinity. This could support some increasing severe potential further east from eastern KS/OK into the mid/lower MS Valley. Overall, forecast uncertainty is somewhat high with lower confidence given several rounds of potential MCSs leading into and continuing through the Day 4-8 period. Read more CHECK UPDATE ZOOM GRAPHIC
