Subj : DAY2SVR: Nws Storm Predic To : All From : Mike Powell Date : Wed Jun 11 2025 07:19:00 ACUS02 KWNS 110558 SWODY2 SPC AC 110557 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1257 AM CDT Wed Jun 11 2025 Valid 121200Z - 131200Z ....THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER PARTS OF THE NORTHERN PLAINS AND TEXAS... ....SUMMARY... Widely scattered strong to severe storms are expected Thursday across parts of the central to northern Plains and Upper Midwest. Isolated strong to severe storms may also occur over parts of Texas. ....Synopsis... The stronger flow aloft will remain over northern portions of the CONUS on Thursday, with a low-amplitude wave moving across the northern Plains. South of there, a weak upper low will move from TX toward the lower to middle MS Valley late. At the surface, a boundary will stretch roughly from SD eastward to the Mid Atlantic, with a large area of mid to upper 60s F across much of the plains and Midwest. A weak is forecast over southwest NE, with an inverted trough extending northeastward toward southern MN. ....Northern Plains... Early day rain/thunderstorms will shift north across eastern SD and southern MN during the day in a zone of warm advection, with air mass recovery to the southwest across NE and western KS/eastern CO. Strong heating and southeast surface winds will yield storms moving off the Front Range, with locally strong gusts or marginal hail. Robust convection will form within the surface trough over NE, extending into southeast SD/western IA/southwest MN as well, with more of a variety of storms expected. Both damaging winds and hail are expected. Shear will be marginal but an MCS cannot be ruled out overnight. ....Much of southern/central/eastern TX... Substantial moisture and instability will again develop with 70s F dewpoints and cool temperatures aloft. Clusters of storms are likely to be ongoing roughly along or east of I-35 much of the day, and areas of strong wind gusts may occur. West of there, stronger heating will occur over southwest TX. Shear will be weak but multicellular convection capable of marginal hail or localized downbursts may occur. ...Jewell.. 06/11/2025 $$ --- SBBSecho 3.20-Linux * Origin: ILink: CCO - capitolcityonline.net (454:3/105) .
