Scattered severe storms will be possible across West/southwest Texas into south-central Texas Tuesday afternoon and night, including potential for large hail, damaging winds and a couple tornadoes. ...Eastern New Mexico and West/south-central Texas... Forcing for ascent will arrive into the region Tuesday afternoon via a lead shortwave trough, with increasing thunderstorm development expected from the Davis Mountains to the Edwards Plateau and to the southern Permian Basin. Moderate instability and steep low to mid-level lapse rates are forecast across the region, with increasing deep layer shear to around 30-40 kt. Mode will likely include initially discrete supercells and multicell clusters capable of large to very large hail and severe wind gusts, along with a tornado risk as low-level winds/SRH increase particularly late in the day across parts of the Permian Basin. Storms should grow upscale by evening as they progress east-southeastward Tuesday night toward south-central Texas with at least some continued severe potential. ...Montana/Northern Intermountain West... Scattered thunderstorms are expected Tuesday afternoon into evening, aided by forcing for ascent related to the amplifying upper trough and the upper-jet exit region. Modest instability and strengthening deep layer shear amid deeply mixed profiles may allow for a few stronger storms with potential for marginally severe hail and locally severe wind gusts. ...Upper Midwest including parts of Wisconsin/Minnesota... While influenced by upper ridging and weak overall forcing for ascent, a moist/moderately unstable environment will exist along/south of generally southward-shifting front. Isolated to widely scattered thunderstorm development is plausible particularly into peak heating. Diurnally steepening low-level lapse rates, upwards of 1500-2500 J/kg MLCAPE within a weak vertical shear (20-30 kt effective) could yield some pulse-type/multicellular storms capable of marginally severe hail and/or locally damaging winds. ...Northern Maine... As a shortwave trough/mid-level jet streak approaches from Quebec, a few strong or locally severe storms could develop into the region Tuesday late afternoon or early evening. Some questions linger regarding the degree of destabilization of timing of relevant features, but this will be reevaluated into the Day 1 time frame for a potential need for severe probabilities. ..Guyer.. 05/25/2026 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
