Severe Storms

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0742 PM CDT Mon Jul 07 2025 Valid 080100Z - 081200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF THE NORTHERN AND CENTRAL PLAINS... ...SUMMARY... Scattered severe thunderstorms will be concentrated across portions of the central and northern Plains. Severe wind and large hail are the main threats. ...01z Update... Mid-level short-wave trough is progressing across the upper Red River Valley, and 500mb flow is gradually strengthening across the northern/central Plains. Associated synoptic front currently extends from eastern ND-central SD-near CYS. This boundary will advance slowly into northern MN, but is not expected to move appreciably across the central High Plains. Convection has largely concentrated along/near the wind shift, but large convective-free gaps are noted, especially over central NE. Even so, there is some expectation for at least isolated robust convection to develop over central NE, partially due to some influence in outflow aiding low-level convergence near the frontal zone. Latest radar data suggests a larger cluster of strong-severe thunderstorms near the SD/NE/IA border will continue to propagate south-southeast, but LLJ is not particularly strong into this complex. Higher-based convection is also concentrated over southwest NE into northwest KS. This activity will also propagate southeast with an attendant risk for wind/hail. Overall, low-level convergence is seasonally weak and this will likely result in scattered pockets of semi-organized convection much of the evening. ..Darrow.. 07/08/2025 Read more

Valid 072252Z - 080015Z The severe weather threat for Severe Thunderstorm Watch 493 continues. SUMMARY...Risk of large hail and severe wind gusts will continue spreading/expanding southward in Severe Thunderstorm Watch 493. DISCUSSION...Thunderstorm clusters are spreading slowly southward along a composite outflow-front in southeastern SD, which will continue to pose a risk of severe wind gusts. Ahead of the front, differential heating amid rich boundary-layer moisture (upper 60s/lower 70s dewpoints) is supporting discrete supercell development within a strongly unstable air mass. Given around 40 kt of effective shear and modest clockwise hodograph curvature (per nearby VWP), discrete supercells will be capable of producing large hail (potentially up to 2 inches in diameter) and locally severe wind gusts. ..Weinman.. 07/07/2025 ...Please see www.spc.noaa.gov for graphic product...

Valid 072228Z - 080000Z The severe weather threat for Severe Thunderstorm Watch 492 continues. SUMMARY...The risk of large hail and severe wind gusts continue across Severe Thunderstorm Watch 492. Some localized upscale growth may support an increasing severe-wind risk into this evening. DISCUSSION...Thunderstorms are gradually increasing in intensity and coverage across parts of northeastern CO into the southwestern NE Panhandle as they impinge on a moderate to strongly unstable boundary layer. Steep deep-layer lapse rates and a long/straight hodograph (around 40 kt of deep-layer shear per mesoanalysis/VWP) will continue to support embedded supercell structures and organized clusters capable of producing large hail and locally severe wind gusts. With time, continued storm mergers amid strong convective outflow may favor some localized upscale growth into one or more coherent clusters into this evening. This evolution would support an increasing risk of severe wind gusts (some upwards of 75 mph). ..Weinman.. 07/07/2025 ...Please see www.spc.noaa.gov for graphic product...

URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 493 NWS Storm Prediction Center Norman OK 315 PM CDT Mon Jul 7 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Northwest Iowa Southwest Minnesota Northeat Nebraska Southeast South Dakota * Effective this Monday afternoon and evening from 315 PM until 1000 PM CDT. * Primary threats include... Scattered large hail likely with isolated very large hail events to 2 inches in diameter possible Scattered damaging wind gusts to 70 mph likely SUMMARY...Thunderstorms are intensifying along a line across southeast South Dakota. These storms will spread across the watch area through the afternoon and early evening, posing a risk of damaging winds and large hail. A tornado or two is possible. The severe thunderstorm watch area is approximately along and 75 statute miles north and south of a line from 50 miles east of Sioux Falls SD to 15 miles north northwest of Ainsworth NE. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU3). PRECAUTIONARY/PREPAREDNESS ACTIONS...
