SPC 1300Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0734 AM CDT Sat Jul 05 2025 Valid 051300Z - 061200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FOR SOUTHEAST MONTANA INTO FAR NORTHEAST WYOMING AND EXTREME NORTHWEST SOUTH DAKOTA... ...SUMMARY... Scattered severe storms are likely across portions of the northern High Plains this afternoon through the evening. Severe gusts ranging from 60-85 mph and large to very large hail are the primary hazards. ...Northern High Plains... Water-vapor imagery this morning shows a mid-level trough over the Pacific Northwest/northern Rockies. A belt of 40-50 kt 500-mb flow will move east from ID across southern MT and northern WY through the late evening. In the low levels, surface low pressure will develop over central WY today to the south of a high centered over SK/MB, aiding in maintaining an easterly component to low-level flow across southern MT. The northern periphery of steep 700-500 mb lapse rates will be atop a destabilizing boundary layer and will contribute to moderate buoyancy. As large-scale ascent overspreads south-central MT by early to mid afternoon coincident with eroding convective inhibition, isolated to scattered thunderstorms are forecast to develop. Ample deep-layer flow will favor a few supercells with the early activity as storms mature/organize. An eastward-moving cluster is forecast to evolve (supported by recent CAM guidance) during the early evening, with a potential swath of severe gusts focused over southeast MT into adjacent parts of WY/SD. As storms move farther east, less buoyancy will tend to limit the severe risk with east extent into parts of the Dakotas. ...Central-Southern High Plains... Scattered thunderstorm development is expected this afternoon into the evening in the vicinity of a lee trough over the central High Plains and farther south closer to the Raton Mesa. A relatively moist and moderately unstable airmass (~1000-2500 J/kg MLCAPE) will support vigorous updrafts mainly in the form of multicells and small clusters. This activity will likely spread east-southeastward into the evening hours. Severe gusts and perhaps large hail may accompany the more intense storms. ...Upper Midwest into the central Plains... A separate midlevel trough will move eastward across the Upper Midwest, while a related cold front advances southeastward across the Upper Midwest and Lower MO Valley during the day. Despite poor midlevel lapse rates, rich boundary-layer moisture and a belt of enhanced low/midlevel flow will support a few strong to severe storms capable of damaging gusts along/ahead of the front. ...Carolina coast... The low-level wind profile is forecast to gradually strengthen concurrent with the approach of Tropical Storm Chantal (see the National Hurricane Center for the latest details regarding Chantal's forecast track). By the evening, hodographs begin to substantially enlarge near the coast and the influx of richer low-level moisture (mid 70s F surface dewpoints) are expected to infiltrate the immediate coast. As such, a few transient supercells are possible with an accompanying low risk for a tornado---mainly during the overnight. ..Smith/Broyles.. 07/05/2025 Read more

Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0346 AM CDT Sat Jul 05 2025 Valid 081200Z - 131200Z ...DISCUSSION... An upper ridge will build across the Southwest and remain in place this upcoming week into next weekend. Relatively zonal mid-level flow will persist over the northern CONUS through the extended forecast period, with multiple embedded impulses expected to track eastward within the zonal flow. As the mid-level impulses traverse the northern Plains, isolated strong to severe storm development will be possible given the presence of ample buoyancy. However, there are appreciable differences in the placement and timing of these impulses among medium-range guidance members. Therefore, severe probabilities have been withheld since confidence is currently low regarding where and when organized clusters of severe storms will develop. Read more

SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0230 AM CDT Sat Jul 05 2025 Valid 071200Z - 081200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR PORTIONS OF THE CENTRAL PLAINS... ...SUMMARY... Severe storms are possible across the central Plains on Monday. Severe wind and hail are the main threats. Isolated strong to potentially severe storms are also possible over the northern Appalachians. ...Synopsis... Zonal mid-level flow will persevere over the northern CONUS as a mid-level trough meanders along the CA coastline on Monday. Mid-level impulses, embedded in the zonal flow aloft, will traverse the Upper MS Valley and New England during the afternoon, acting as a source of lift amid adequate moisture, instability, and vertical wind shear, to support the potential for strong thunderstorms, a few of which could become severe, especially over the central Plains. ...Central Plains into the Upper MS Valley... A weak surface low will develop across the central High Plains and augment northward moisture transport beneath a plume of steep mid-level lapse rates. 60 F surface dewpoints beneath 8 C/km mid-level lapse rates will yield 2000+ J/kg MLCAPE by peak heating. Furthermore modest northwesterly 500 mb flow associated with the impulse will overspread the central Plains, resulting in 40 kts of effective bulk shear. Given modestly elongated and curved hodographs, supercells may develop, accompanied by a severe wind and hail threat (with a few stones potentially exceeding 2 inches in diameter). A tornado is also possible, particularly in central Nebraska, where forecast hodographs show larger, curved low-level hodographs. Storms may grow upscale into an MCS by evening, accompanied by mainly a severe gust threat. Strong storms may develop farther northeast into the Upper MS Valley during the late afternoon/early evening hours. Though buoyancy will be slightly weaker compared to the central Plains, elongated hodographs suggest that a few supercells may produce isolated instances of severe hail. ...Portions of the Northern Appalachians... A mid-level impulse embedded in the 500 mb flow will impinge on the northern Appalachians by afternoon peak heating, providing enough lift for convective initiation. Near 70F surface dewpoints beneath modest lapse rates will contribute to 2000 J/kg MLCAPE in tall/thin thermodynamic profiles. Forecast soundings depict hodographs with some low-level curvature and size, suggesting that some storms may become strong and organized. Multicells and supercells may pose a damaging gust threat. ..Squitieri.. 07/05/2025 Read more
