SPC Jun 11, 2023 Day 4-8 Severe Weather Outlook

LIVE MAP (ABOVE) ... Day 4-8 Outlook Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0350 AM CDT Sun Jun 11 2023 Valid 141200Z - 191200Z ...DISCUSSION... As the remnants of a mid-level low emerging from the Great Basin, and an associated belt of stronger flow, progress through somewhat more amplified larger-scale mid-level troughing across the Southeast this coming Wednesday into Thursday, deep-layer shear may be potentially conducive to the evolution of organizing clusters of storms capable of produce damaging wind gusts. However, the influence of prior convection on the boundary-layer near and south of a remnant frontal zone across this region becomes more unclear during this time frame, and the predictability remains low. Later this work week into next weekend, the ECENS and GEFS indicate a more amplified regime evolving, including large-scale mid-level troughing across the Pacific Coast into the Intermountain West and downstream mid-level ridging across much of the Great Plains and Mississippi Valley. However, it appears that seasonably moist air may remain largely confined to parts of the Southeast into the lower southern and central Great Plains, where increasing mid-level inhibition and/or weakening flow may tend to suppress convective potential.
