208 ACUS48 KWNS 140824 SWOD48 SPC AC 140823 Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0323 AM CDT Fri Jun 14 2024 Valid 171200Z - 221200Z ...DISCUSSION... Models indicate a strong upper ridge over much of the East and mean troughing over the western states for much of the period. While moderate southwest flow aloft will persist over parts of the northern Rockies and Plains, timing of the emerging features is uncertain. At this time, it appears a shortwave trough may move into the northern Plains on Tue/D5 as opposed to Mon/D4. Further, significant areas of early day convection appear possible on Mon/D4 and Tue/D5, which reduces predictability further. However, air mass recovery is likely over parts of the northern Plains/Upper MS Valley on Mon/D4, with clusters of storms producing areas of damaging wind and locally severe hail. As such, will maintain the ongoing 15% area for Mon/D4. Additional areas of severe hail/wind will be possible on Tuesday/D5, but predictability is low given the tendency for the eastern ridge to hold. ..Jewell.. 06/14/2024
