SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0104 AM CDT Sun Apr 27 2025 Valid 271200Z - 281200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR MUCH OF THE GREAT PLAINS... ...SUMMARY... Isolated to scattered severe thunderstorms are possible on Sunday evening into early morning Monday across parts of the Great Plains. Large hail, severe gusts, and a few tornadoes are all possible. ...Synopsis... A deep mid/upper-level trough will move eastward across the western CONUS today. A strong jet will move through the base of the trough and begin to impinge on the central/southern Great Plains by evening. The primary surface low will deepen through the day over the central High Plains and move northeast across NE/SD late tonight. A secondary surface low is expected to develop near/west of the Black Hills during the afternoon. A lee trough/dryline will extend southward into the southern High Plains. Relatively rich low-level moisture will initially be confined to the southern Plains this morning, but will stream quickly northward later today and tonight in advance of the surface lows and dryline. ...Northern Great Plains... Large-scale ascent is expected to increase by evening across the northern Great Plains vicinity, in association with the approaching mid/upper-level trough and jet that will overspread the region. Richer low-level moisture will remain mostly south of this region through much of the day, but steep midlevel lapse rates, moderate buoyancy, and increasing deep-layer shear will support development of a few supercells by evening with a threat of hail and damaging winds. The longevity of any surface-based storms is uncertain and could be limited, but some tornado threat could evolve with any supercells that can persist into the evening, as low-level moisture and shear continue to increase. Some clustering and upscale growth will be possible later tonight, with a threat for hail and damaging wind potentially spreading eastward across the Dakotas into MN before the end of the period. ...Central/southern High Plains... Conditionally, the warm-sector environment across the central and southern High Plains will become quite favorable for organized convection, with strong instability developing by late afternoon in conjunction with strengthening low-level and deep-layer shear. However, despite diminishing MLCINH from afternoon into early evening near the dryline, there is only an inconsistent and relatively limited signal for initiation. One area of potential development will be from west-central NE into northwest KS, in the vicinity of the primary surface low. Guidance also has a somewhat stronger signal for development into parts of the southern High Plains, where strong heating/mixing may result in more favorable low-level convergence on the dryline. There is a relative minimum in signal for storm development from west-central/southwest KS toward the OK Panhandle, but any supercell that develops within this region would be within an increasingly volatile environment during the evening, and pose an all-hazards severe threat. Given the very favorable environment and at least some potential for isolated supercell development by early evening in the vicinity of the dryline, the Slight Risk has been expanded southward for the conditional all-hazards threat. It remains possible that portions of the Slight Risk may see little or no storm development. ..Dean/Halbert.. 04/27/2025 Read more

MD 0573 CONCERNING TORNADO WATCH 175... FOR EASTERN NEW MEXICO
Mesoscale Discussion 0573 NWS Storm Prediction Center Norman OK 0713 PM CDT Sat Apr 26 2025 Areas affected...Eastern New Mexico Concerning...Tornado Watch 175... Valid 270013Z - 270215Z The severe weather threat for Tornado Watch 175 continues. SUMMARY...The tornado threat across WW 175 will continue into the early evening, particularly in the vicinity of two isolated supercells near Roswell and Fort Sumner, NM. DISCUSSION...A pair of rightward-moving supercells have developed along and east of a dryline in eastern New Mexico. Recent trends in the KFDX VAD wind profiles show increasing low-level curvature of the hodograph, which should continue to enlarge this evening with the onset of the nocturnal low-level jet. Easterly surface winds that are antiparallel to the westerly storm-motion vectors will result in an overall enhancement of the storm-relative inflow near the surface, supporting robust updraft development and maintenance into the early evening hours. These supercells will be capable of 60+ MPH winds, 2.0+ inch hail, and tornadoes. Short-term forecast guidance does suggest the boundary layer will begin to stabilize with eastward extent after 01Z, limiting some of the tornado threat after dark, but persistent mesocyclones fed by strong storm-relative inflow may be able to persist a little while longer after dark. ..Halbert.. 04/27/2025 ...Please see www.spc.noaa.gov for graphic product...

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0800 PM CDT Sat Apr 26 2025 Valid 270100Z - 271200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR PARTS OF EASTERN NM INTO SOUTHWEST TX...AND ALSO NEAR THE ARKLATEX VICINITY... ...SUMMARY... Scattered severe thunderstorms may continue over eastern New Mexico into parts of west Texas through the evening. A threat for large to very large hail and a couple of tornadoes are the primary risks. Scattered strong to severe storms also remain possible across parts of western/central Arkansas and vicinity. ...Eastern NM into west/central TX... Widely scattered supercells are ongoing this evening from east-central NM into the TX Permian Basin region, near and to the south of a remnant outflow boundary that earlier moved into the region from the east. MLCINH will increase through the evening across the region, and the eastward advance of the NM storms may be limited by a less unstable and increasingly capped airmass to the cool side of the remnant outflow. However, a modest increase in low-level flow through the evening may help to maintain a couple of these supercells, which will tend to propagate southeastward along the instability gradient. Backed low-level flow and modestly enlarged hodographs may continue to support tornado potential with these cells for as long as they persist and remain surface-based. Otherwise, large to very large hail and localized severe gusts will remain a threat with the strongest storms. Farther east, an isolated strong storm or two may yet develop within a persistent cumulus field across parts of central TX. Moderate instability and deep-layer shear could support at least briefly organized storms if initiation occurs, with a threat of isolated hail and strong gusts. ...Western/central AR and vicinity... Moderate instability and modestly enhanced midlevel flow attendant to an MCV over eastern OK have supported occasional supercell structures early this evening from western AR into the ArkLaTex region. A few stronger cells may persist through dusk, accompanied by a threat of hail, isolated damaging wind, and possibly a tornado or two. A gradual weakening trend is expected later this evening after the onset of nocturnal cooling, though relatively rich low-level moisture may delay this process somewhat and allow for some severe threat to spread into parts of central AR with time. ...Parts of the Carolinas/southeast VA... Widely scattered storms are ongoing this evening from the eastern Carolinas into southeast VA, along/ahead of a cold front. MLCAPE around 1000 J/kg and modest deep-layer shear could support occasionally strong storms with potential for locally gusty/damaging winds, before storms weaken later this evening. ..Dean.. 04/27/2025 Read more

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0800 PM CDT Sat Apr 26 2025 Valid 270100Z - 271200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR PARTS OF EASTERN NM INTO SOUTHWEST TX...AND ALSO NEAR THE ARKLATEX VICINITY... ...SUMMARY... Scattered severe thunderstorms may continue over eastern New Mexico into parts of west Texas through the evening. A threat for large to very large hail and a couple of tornadoes are the primary risks. Scattered strong to severe storms also remain possible across parts of western/central Arkansas and vicinity. ...Eastern NM into west/central TX... Widely scattered supercells are ongoing this evening from east-central NM into the TX Permian Basin region, near and to the south of a remnant outflow boundary that earlier moved into the region from the east. MLCINH will increase through the evening across the region, and the eastward advance of the NM storms may be limited by a less unstable and increasingly capped airmass to the cool side of the remnant outflow. However, a modest increase in low-level flow through the evening may help to maintain a couple of these supercells, which will tend to propagate southeastward along the instability gradient. Backed low-level flow and modestly enlarged hodographs may continue to support tornado potential with these cells for as long as they persist and remain surface-based. Otherwise, large to very large hail and localized severe gusts will remain a threat with the strongest storms. Farther east, an isolated strong storm or two may yet develop within a persistent cumulus field across parts of central TX. Moderate instability and deep-layer shear could support at least briefly organized storms if initiation occurs, with a threat of isolated hail and strong gusts. ...Western/central AR and vicinity... Moderate instability and modestly enhanced midlevel flow attendant to an MCV over eastern OK have supported occasional supercell structures early this evening from western AR into the ArkLaTex region. A few stronger cells may persist through dusk, accompanied by a threat of hail, isolated damaging wind, and possibly a tornado or two. A gradual weakening trend is expected later this evening after the onset of nocturnal cooling, though relatively rich low-level moisture may delay this process somewhat and allow for some severe threat to spread into parts of central AR with time. ...Parts of the Carolinas/southeast VA... Widely scattered storms are ongoing this evening from the eastern Carolinas into southeast VA, along/ahead of a cold front. MLCAPE around 1000 J/kg and modest deep-layer shear could support occasionally strong storms with potential for locally gusty/damaging winds, before storms weaken later this evening. ..Dean.. 04/27/2025 Read more
