SPC Aug 9, 2021 0100 UTC Day 1 Convective Outlook

SPC 0100Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0750 PM CDT Sun Aug 08 2021 Valid 090100Z - 091200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM PORTIONS OF SOUTHEASTERN KANSAS/NORTHEASTERN OKLAHOMA EASTWARD ACROSS THE OZARK PLATEAU... ...SUMMARY... A few severe thunderstorms capable of producing damaging winds and large hail should continue this evening from southeastern Kansas and vicinity eastward across the Ozark Plateau. Isolated severe storms are also possible northward to Iowa and portions of southern Minnesota/southern Wisconsin. A strong gust or two also may occur across portions of Montana. ...Discussion... A broken band of storms -- a few strong/locally severe -- extends from the Lake Michigan vicinity southward to far southeastern Missouri and continues moving eastward. A general decrease in intensity is expected with this band over the next few hours. Meanwhile, some new convective development is underway farther westward, across northern Iowa near the center of circulation aloft, and over parts of southern Kansas in a zone of low-level warm advection. While severe risk should remain isolated at best across the Iowa vicinity, it remains apparent that storms should continue to increase across southern Kansas, and into portions of Missouri this evening (with a favorable thermodynamic and kinematic environment indicated by RUC-based objective analyses and confirmed by the 00Z SGF RAOB). Locally damaging winds and hail will be possible with the stronger storms in this area. Finally, showers and isolated storms continue moving across central and eastern Montana. Though weak instability -- and the onset of diurnal cooling -- should limit storm intensity, a stronger gust or two remain possible over the next few hours. ..Goss.. 08/09/2021 Read more LIVE:
