BBS: TELESC.NET.BR Assunto: DAY2SVR: Nws Storm Prediction Center Norman Ok De: COD Weather Processor Data: Thu, 28 May 2026 05:52:59 +0000 ----------------------------------------------------------- ACUS02 KWNS 280552 SWODY2 SPC AC 280551 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1251 AM CDT Thu May 28 2026 Valid 291200Z - 301200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER WESTERN AND CENTRAL MONTANA...AND PARTS OF THE CENTRAL HIGH PLAINS AND SOUTHERN PLAINS... ...SUMMARY... A few storms may produce marginal hail or strong gusts from eastern New Mexico and western Texas across Oklahoma and toward northern Louisiana on Friday. A few strong to severe storms may also occur across western Montana with gusty winds and marginal hail. Isolated damaging wind gusts are also possible across portions of the central High Plains. ...MT... An upper low will weaken as it moves from the Great Basin to the central Rockies, with cool temperatures aloft persisting over much of the region. A surface trough will deepen over central MT with a cold front moving across ID and into western MT. Daytime heating and steepening lapse rates may aid wind gust potential as storms develop late in the day from western into central MT. Relatively strong upper-level winds will elongate hodographs, and may support cells producing marginal hail. ...Central High Plains... Low-level moisture will spread westward into northern CO and eastern WY as a low pressure trough develops from MT into eastern CO during the afternoon. Steep lapse rates and 50s F dewpoints will result in perhaps 1000 J/kg MUCAPE supporting storms forming from southeast WY into the Front Range. These storms may produce strong to locally severe outflow winds. ...Southern Plains... An upper-level jet of 50-70 kt will move into southern NM and western TX, though midlevel winds will be at or below 30 kt. Strong heating will occur over the region while southeast surface winds maintain moisture influx. Storms should form during the afternoon from eastern NM and spread across western TX and perhaps into southwest KS. Cool midlevel temperatures may support marginal hail, though gusty outflow winds will be the most common threat. Additionally, a few storms may occur farther east from OK into northeast TX, AR and LA where dewpoints and instability will be greater. Any storms that can form within the uncapped air mass would likely move southeastward with isolated strong gust potential. ..Jewell.. 05/28/2026 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
