Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0354 AM CDT Tue Apr 29 2025 Valid 021200Z - 071200Z ...DISCUSSION... The severe potential remains limited through the day 4-8 period. On D4/Friday, an upper level trough will be located across the eastern US with strengthening upper level ridging across the western US into the Rockies. Along the dryline in far western Texas, a few thunderstorms capable of large hail will be possible. This threat may be limited in duration and coverage by the southward moving cold front expected to extend from the southern Plains into the northeastern US. As this front shifts southward and a surface high builds in across the central US D5/Saturday into D6/Sunday, moisture will be scoured out of much of the CONUS limiting the severe threat. As the surface high shifts eastward across the Midwest, slow moisture return will begin across the southern Plains late D6/Sunday into D7/Monday. During this period, the next upper-level wave will be deepening across the western US. As this system evolves, severe potential may return late in the period across portions of the southern and central Plains.
