Day 4-8 Outlook Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0358 AM CST Fri Feb 28 2025 Valid 031200Z - 081200Z ...DISCUSSION... Medium-range guidance suggests that an initially zonal, intense mid/upper jet across the western into central mid-latitude Pacific may undergo considerable amplification into and through this period. It remains a bit unclear how emerging waves will impact the downstream pattern by the middle to latter portion of next week. However, it still appears that one significant preceding short wave trough, migrating inland of the Pacific coast by early Monday, will progress into and across the southern

Isolated to scattered thunderstorms are possible from the Mid and Upper Ohio Valley to the Carolinas/southern Virginia. ...Synopsis... Recent satellite imagery shows a pair of shortwave troughs moving through the broadly cyclonic flow aloft extending from the northern/central Plains and southern Canadian Prairies into the OH Valley and Northeast. The lead wave in the pair is currently over the Upper OH Valley, and should continue northeastward through the

A compact mid-level low will translate east across the Southwest on Sunday 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 as it moves across the Plains and into the
