Subj : DAY1SVR: Day 1 Convective Outlook To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Tue Jul 08 2025 00:43:57 ACUS01 KWNS 080043 SWODY1 SPC AC 080042 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0742 PM CDT Mon Jul 07 2025 Valid 080100Z - 081200Z ....THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF THE NORTHERN AND CENTRAL PLAINS... ....SUMMARY... Scattered severe thunderstorms will be concentrated across portions of the central and northern Plains. Severe wind and large hail are the main threats. ....01z Update... Mid-level short-wave trough is progressing across the upper Red River Valley, and 500mb flow is gradually strengthening across the northern/central Plains. Associated synoptic front currently extends from eastern ND-central SD-near CYS. This boundary will advance slowly into northern MN, but is not expected to move appreciably across the central High Plains. Convection has largely concentrated along/near the wind shift, but large convective-free gaps are noted, especially over central NE. Even so, there is some expectation for at least isolated robust convection to develop over central NE, partially due to some influence in outflow aiding low-level convergence near the frontal zone. Latest radar data suggests a larger cluster of strong-severe thunderstorms near the SD/NE/IA border will continue to propagate south-southeast, but LLJ is not particularly strong into this complex. Higher-based convection is also concentrated over southwest NE into northwest KS. This activity will also propagate southeast with an attendant risk for wind/hail. Overall, low-level convergence is seasonally weak and this will likely result in scattered pockets of semi-organized convection much of the evening. ...Darrow.. 07/08/2025 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
