MD 1729 CONCERNING SEVERE THUNDERSTORM WATCH 529... FOR SOUTH-CENTRAL NEBRASKA INTO FAR NORTH-CENTRAL KANSAS
Mesoscale Discussion 1729 NWS Storm Prediction Center Norman OK 0705 PM CDT Sat Jul 19 2025 Areas affected...South-central Nebraska into far north-central Kansas Concerning...Severe Thunderstorm Watch 529... Valid 200005Z - 200130Z The severe weather threat for Severe Thunderstorm Watch 529 continues. SUMMARY...A narrow window for a locally greater tornado threat will exist with supercells in south-central Nebraska. An additional risk of severe/damaging winds is also possible as this activity grows upscale. DISCUSSION...Two supercells continue to move southeastward into south-central Nebraska early this evening. With low-level hodographs from KUEX showing an increase in low-level SRH over the last hour, these storms will have some potential to produce a tornado. However, that window of opportunity may be relative confined in time given the ongoing signs of upscale growth on local radar. When this occurs, a greater threat for severe/damaging wind gusts would exist. Large hail remains possible, but MRMS MESH estimates have come down as storm interaction has steadily increased. ..Wendt.. 07/20/2025 ...Please see www.spc.noaa.gov for graphic product...

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0800 PM CDT Sat Jul 19 2025 Valid 200100Z - 201200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR PARTS OF THE NORTHERN AND CENTRAL HIGH PLAINS INTO THE MIDWEST... ...SUMMARY... Strong to severe storms remain possible this evening into late tonight from parts of the central and northern High Plains into parts of the Corn Belt. ...Central Plains into parts of IA/IL... Strong to extreme buoyancy and favorable deep-layer shear (as noted on the 00Z OAX sounding) remain in place across much of NE into western/central IA. Ongoing supercells will continue to pose a threat for large hail, localized severe gusts, and possibly a tornado or two through much of the evening. A nocturnally strengthening low-level jet may support an increase in storm coverage later tonight from eastern NE into parts of IA. Potential for organized MCS development remains uncertain, but any substantial storm clustering could result in a damaging wind and isolated hail threat spreading eastward overnight, potentially reaching parts of northern IL before the end of the period. ...Northern High Plains... Widely scattered supercells may persist through much of the evening across the northern High Plains, within an environment characterized by moderate to strong instability and favorable deep-layer shear (as depicted in the 00Z GGW and UNR soundings). Large hail and localized severe gusts may accompany the strongest storms. Some modest upscale growth is possible late tonight from eastern MT into ND, in association with a mid/upper-level shortwave trough moving across southern SK. While an isolated severe threat could continue across this region into the overnight hours, decreasing instability and increasing CINH should eventually result in a gradual weakening trend. ...Mid Atlantic... A few strong storms are ongoing this evening from eastern VA into NC. Localized wind damage remains possible with the strongest remaining storms, though the threat should eventually diminish as storms weaken with time and/or move offshore. ...WI/Lower MI vicinity... Some increase in storm coverage remains possible this evening across parts of WI and lower MI, in the vicinity of a cold front. Modest buoyancy and moderate deep-layer shear could support a strong storm or two capable of locally damaging wind. ..Dean.. 07/20/2025 Read more

Ongoing supercells will continue to pose a threat for large hail, localized severe gusts, and possibly a tornado or two through much of the evening. A nocturnally strengthening low-level jet may support an increase in storm coverage later tonight from eastern NE into parts of IA. Potential for organized MCS development remains uncertain, but any substantial storm clustering could result in a damaging wind and isolated hail threat spreading eastward overnight, potentially reaching parts of northern IL before the end of the period. ...Northern High Plains... Widely scattered supercells may persist through much of the evening across the northern High Plains, within an environment characterized by moderate to strong instability and favorable deep-layer shear (as depicted in the 00Z GGW and UNR soundings). Large hail and localized severe gusts may accompany the strongest storms. Some modest upscale growth is possible late tonight from eastern MT into ND, in association with a mid/upper-level shortwave trough moving across southern SK. While an isolated severe threat could continue across this region into the overnight hours, decreasing instability and increasing CINH should eventually result in a gradual weakening trend. ...Mid Atlantic... A few strong storms are ongoing this evening from eastern VA into NC. Localized wind damage remains possible with the strongest remaining storms, though the threat should eventually diminish as storms weaken with time and/or move offshore. ...WI/Lower MI vicinity... Some increase in storm coverage remains possible this evening across parts of WI and lower MI, in the vicinity of a cold front. Modest buoyancy and moderate deep-layer shear could support a strong storm or two capable of locally damaging wind. ..Dean.. 07/20/2025 Read more
