MD 1888 CONCERNING SEVERE THUNDERSTORM WATCH 571...572... FOR CENTRAL HIGH PLAINS
Mesoscale Discussion 1888 NWS Storm Prediction Center Norman OK 0746 PM CDT Mon Aug 04 2025 Areas affected...central High Plains Concerning...Severe Thunderstorm Watch 571...572... Valid 050046Z - 050245Z The severe weather threat for Severe Thunderstorm Watch 571, 572 continues. SUMMARY...Widely spaced severe storms persist across the central High Plains, with mainly a large hail threat. These storms should remain within a relatively narrow north-south corridor this evening. DISCUSSION...Two main clusters of cells persist this evening over eastern CO where southeast low-level winds have maintained lower 60s F dewpoints. Modest northwest flow aloft exists as well, helping to elongate hodographs with splitting cells noted earlier. Recently, cells have accelerated in a relative sense, now with southward propagation into the increasing nocturnal low-level jet. Increasing MLCIN as seen on available 00Z soundings suggest the existing storm corridor will not shift eastward much, but perhaps toward the CO/KS border. The cluster of storms west of GLD has shown some eastward progression recently as outflow increases. For areas from far southeast CO into northeast NM and the western Panhandles, capping is not as strong and this region will remain firmly within the 850 mb theta-e plume. As such, at least isolated cells may persist well into the evening with hail and localized wind threat. ..Jewell.. 08/05/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 1887 CONCERNING SEVERE THUNDERSTORM WATCH 573... FOR PARTS OF CENTRAL MONTANA
Mesoscale Discussion 1887 NWS Storm Prediction Center Norman OK 0743 PM CDT Mon Aug 04 2025 Areas affected...Parts of central Montana Concerning...Severe Thunderstorm Watch 573... Valid 050043Z - 050215Z The severe weather threat for Severe Thunderstorm Watch 573 continues. SUMMARY...Thunderstorms will continue increasing in intensity and coverage while spreading northeastward across Severe Thunderstorm Watch 573. Severe wind gusts and isolated large hail are the main concerns. DISCUSSION...The latest water-vapor imagery indicates strengthening midlevel ascent impinging on western/central MT this evening -- preceding a compact/negative-tilt midlevel trough over the northern Rockies. Regional VWP data shows strengthening midlevel southwesterly flow ahead of the trough, which is contributing to around 40 kt of deep-layer shear. In response to these factors, thunderstorms will continue increasing in intensity and coverage while spreading/developing northeastward across central MT -- within Severe Thunderstorm Watch 573. The strengthening large-scale ascent, well-mixed boundary layer, and favorable deep-layer shear is favoring the development of a loosely organized broken band of storms, capable of producing severe outflow winds. However, the west-southwesterly deep-layer shear vectors (orthogonal to the developing larger-scale cold pool) are also supporting semi-discrete supercell structures along the evolving convective band, as well as ahead of this activity. Large hail is also a concern with these more discrete storms. ..Weinman.. 08/05/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...BYZ...GGW...TFX...
