SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0817 PM CDT Sat May 25 2024 Valid 260100Z - 261200Z ...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS FOR PARTS OF NORTHERN OK...SOUTH-CENTRAL/SOUTHEAST KS...SOUTHWEST MO... ...SUMMARY... Widespread strong to severe storms remain possible tonight across parts of the central and southern Plains into southern Missouri. A few strong tornadoes, widespread damaging wind, and very large hail will be possible. ...Central/southern Plains into southern MO/northern AR... Extensive and relatively early storm development this afternoon across parts of OK and northwest TX has significantly complicated the distribution of moisture and instability across parts of the central/southern Plains. However, a strong low-level jet will continue to transport moisture into the region tonight, and some recovery and additional storm development in the vicinity of convective outflow remains possible through the evening. Supercells capable of very large hail, significant gusts, and a few strong tornadoes remain possible where surface-based storms can persist. Later tonight, some upscale growth will be possible from southern MO into northern AR, as the low-level jet continues to strengthen into the overnight hours. An increasing risk of severe to locally destructive wind gusts (60-85 mph) may accompany this upscale growth. However, embedded supercells will remain possible, with very strong low-level shear/SRH supporting a continued tornado threat, including some potential for a strong tornado. A relatively intense storm cluster or MCS could reach portions of the MS Valley by the end of the period. Farther north, increasing storm coverage is expected from northern KS into southern NE. Low-level moisture will continue to surge northward in conjunction with a warm front, which may eventually reach the KS/NE border region. A few supercells will be possible across the region this evening, with a threat of large to very large hail. The tornado threat will also increase with cells near and south of the warm front, and a strong tornado cannot be ruled out with any persistent discrete supercell. Some upscale growth will be possible with time from eastern KS into western MO, with a storm cluster or small MCS potentially following in the wake of an earlier storm cluster into parts of southern MO by the end of the period. ...South FL... Isolated strong to locally severe storms remain possible for a couple hours this evening across parts of south FL, within a moderately unstable and modestly sheared environment. Isolated hail and strong wind gusts cannot be ruled out before storms weaken later tonight. ...Parts of MS/AL... A few strong storms are ongoing this evening across parts of eastern MS into AL. While midlevel lapse rates are generally weak across the region, rich low-level moisture is supporting MLCAPE in excess of 2000 J/kg, in the presence of moderate effective shear (generally 30-40 kt). Isolated hail and damaging gusts cannot be ruled out with the strongest storms this evening, before storms generally weaken as MLCINH increases. ...Western PA/northern WV into parts of the Mid Atlantic... Strong to occasionally severe storms have been ongoing across parts of PA/WV and northern MD this evening, within an environment characterized by weak to locally moderate buoyancy and modest deep-layer shear. These storms should generally weaken with the onset of nocturnal cooling/stabilization, though isolated damaging gusts and marginal hail cannot be ruled out through the evening. ..Dean.. 05/26/2024 Read more

A few strong tornadoes, widespread damaging wind, and very large hail will be possible. ...Central/southern Plains into southern MO/northern AR... Extensive and relatively early storm development this afternoon across parts of OK and northwest TX has significantly complicated the distribution of moisture and instability across parts of the central/southern Plains. However, a strong low-level jet will continue to transport moisture into the region tonight, and some recovery and additional storm development in the vicinity of convective outflow remains possible through the evening. Supercells capable of very large hail, significant gusts, and a few strong tornadoes remain possible where surface-based storms can persist. Later tonight, some upscale growth will be possible from southern MO into northern AR, as the low-level jet continues to strengthen into the overnight hours. An increasing risk of severe to locally destructive wind gusts (60-85 mph) may accompany this upscale growth. However, embedded supercells will remain possible, with very strong low-level shear/SRH supporting a continued tornado threat, including some potential for a strong tornado. A relatively intense storm cluster or MCS could reach portions of the MS Valley by the end of the period. Farther north, increasing storm coverage is expected from northern KS into southern NE. Low-level moisture will continue to surge northward in conjunction with a warm front, which may eventually reach the KS/NE border region. A few supercells will be possible across the region this evening, with a threat of large to very large hail. The tornado threat will also increase with cells near and south of the warm front, and a strong tornado cannot be ruled out with any persistent discrete supercell. Some upscale growth will be possible with time from eastern KS into western MO, with a storm cluster or small MCS potentially following in the wake of an earlier storm cluster into parts of southern MO by the end of the period. ...South FL... Isolated strong to locally severe storms remain possible for a couple hours this evening across parts of south FL, within a moderately unstable and modestly sheared environment. Isolated hail and strong wind gusts cannot be ruled out before storms weaken later tonight. ...Parts of MS/AL... A few strong storms are ongoing this evening across parts of eastern MS into AL. While midlevel lapse rates are generally weak across the region, rich low-level moisture is supporting MLCAPE in excess of 2000 J/kg, in the presence of moderate effective shear (generally 30-40 kt). Isolated hail and damaging gusts cannot be ruled out with the strongest storms this evening, before storms generally weaken as MLCINH increases. ...Western PA/northern WV into parts of the Mid Atlantic... Strong to occasionally severe storms have been ongoing across parts of PA/WV and northern MD this evening, within an environment characterized by weak to locally moderate buoyancy and modest deep-layer shear. These storms should generally weaken with the onset of nocturnal cooling/stabilization, though isolated damaging gusts and marginal hail cannot be ruled out through the evening. ..Dean.. 05/26/2024 Read more
