SPC Feb 26, 2025 Day 4-8 Severe Weather Outlook

Day 4-8 Outlook Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0354 AM CST Wed Feb 26 2025 Valid 011200Z - 061200Z ...DISCUSSION... Severe weather potential will be low to start the period with northerly flow across the Gulf on D4/Saturday. On D5/Sunday, a compact mid-level low will translate east across the Southwest which will result in lee cyclogenesis in the southern/central High Plains. As surface high pressure across the Midwest translates east, favorable low-level trajectories and strengthening flow across the Gulf and southern Plains will initiate significant moisture return across Texas. The initial mid-level low will weaken
