SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0754 PM CDT Mon May 25 2020 Valid 260100Z - 261200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER MUCH OF SOUTHERN TEXAS...AND OVER PARTS OF THE OZARKS... ...SUMMARY... Severe thunderstorms are expected this evening into tonight across much of southern Texas, with damaging wind and hail. Additional severe storms remain possible across portions of the Ozarks through this evening, the main hazard being a brief tornado. ...Much of southern TX... Several intense cells persist as of 01Z across the Rio Grande Valley, likely producing damaging hail. Storm coverage will increase tonight as the shortwave trough digs south, and substantial large-scale lift is incurred. Linear forcing along the developing cold front as well as an eventual merging of outflow may result in an MCS producing damaging winds. Capping appears relatively minimal for this region with storms reaching the coast before 12Z. ...Eastern OK, western AR, southwest MO area... Multiple arcing lines of storms persist from northern LA across AR and into northeast OK in association with a midlevel wave. Ahead of these storms, a moist and unstable air mass remains which should sustain them for several hours. Low-level shear will remain favorable for rotating storms and a brief tornado as 850 mb winds increase to 50 kt out of the southeast this evening.
