WW 595 SEVERE TSTM IA MN 160825Z - 161400Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 595 NWS Storm Prediction Center Norman OK 325 AM CDT Sat Aug 16 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Northwest Iowa Southern Minnesota * Effective this Saturday morning from 325 AM until 900 AM CDT. * Primary threats include... Scattered damaging winds likely with isolated significant gusts to 85 mph possible Scattered large hail events to 1.5 inches in diameter possible SUMMARY...A fast-moving and intense cluster of thunderstorms over southeast South Dakota will race eastward across the watch area during the next several hours. Locally damaging wind gusts, including some potential for significant wind damage is expected. The severe thunderstorm watch area is approximately along and 60 statute miles north and south of a line from 70 miles northwest of Worthington MN to 40 miles southeast of Minneapolis MN. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU5). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. Severe thunderstorms can and occasionally do produce tornadoes. && OTHER WATCH INFORMATION...CONTINUE...WW 594... AVIATION...A few severe thunderstorms with hail surface and aloft to 1.5 inches. Extreme turbulence and surface wind gusts to 75 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 27040. ...Hart Read more

SPC 1300Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0721 AM CDT Sat Aug 16 2025 Valid 161300Z - 171200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND TONIGHT OVER PARTS OF SOUTH DAKOTA... ...SUMMARY... Scattered strong/severe thunderstorms are possible today into tonight across parts of the northern Great Plains into Midwest and Great Lakes region. ...MN/Great Lakes Region... A long-lived severe MCS that affected parts of SD and southwest MN overnight has weakened in east-central MN. These storms will track eastward this morning into a region of moderate MUCAPE, but slightly cooler/drier surface air over WI that was affected by one or more areas of thunderstorms yesterday. For this reason, these storms are expected to struggle to organize, with locally gusty winds being the main concern today. Refer to MCD #1963 for further short-term details. Farther south across parts of IA/IL/IN, an overnight MCS pushed the effective surface boundary south into northeast MO and central IL. Strong daytime heating and southerly low-level winds will help the boundary to retreat back into northern IA/IL by mid-afternoon. The corridor along/north of the boundary should provide the greatest potential for re-development of a few storms later today, with locally damaging wind gusts possible. Given the uncertainty of where the boundary is, and anticipated limited coverage of storms, will maintain MRGL risk at this time. ...SD and Vicinity... A well-defined but rather weak shortwave trough is currently over western CO and will spread into eastern WY/western Dakotas by evening. Similar to yesterday, high-based storms will develop ahead of the approaching trough and intensify as they move eastward into a progressively more moist/unstable air mass over west-central SD. Another nocturnal MCS may affect central/eastern SD tonight, with a risk of damaging wind gusts and some hail. ..Hart/Dean.. 08/16/2025 Read more

MD 1962 CONCERNING SEVERE THUNDERSTORM WATCH 594...595... FOR EXTREME EASTERN SD INTO SOUTHERN/CENTRAL MN
Mesoscale Discussion 1962 NWS Storm Prediction Center Norman OK 0501 AM CDT Sat Aug 16 2025 Areas affected...Extreme eastern SD into southern/central MN Concerning...Severe Thunderstorm Watch 594...595... Valid 161001Z - 161130Z The severe weather threat for Severe Thunderstorm Watch 594, 595 continues. SUMMARY...A damaging-wind threat will continue through dawn. DISCUSSION...A small bowing MCS has moved across parts of central/eastern SD early this morning, producing a swath of 55-70 mph gusts, with localized gusts to near 80 mph. The system has become somewhat complex, with significant downstream convection across southwest MN, but very favorable instability (with MUCAPE of 3000-4000 J/kg) may continue to support an organized severe-wind threat as this MCS moves east-northeastward across southern/central MN. The strongest recent gusts have been with the northern portion of the line, and if this trend continues, local expansion of WW 595 may be needed to encompass the northern extent of the threat. Farther south, some intensification and reorganization remains possible, as the primary cold pool and gust front intercept ongoing convection. Convection within the low-level warm-advection regime ahead of the main line may also continue to pose a threat of isolated hail and strong to locally severe gusts as it spreads northeastward. ..Dean/Hart.. 08/16/2025 ...Please see www.spc.noaa.gov for graphic product...

WW 594 SEVERE TSTM SD 160500Z - 161100Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 594 NWS Storm Prediction Center Norman OK 1200 AM CDT Sat Aug 16 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Central and Eastern South Dakota * Effective this Saturday morning from Midnight until 600 AM CDT. * Primary threats include... Scattered damaging winds likely with isolated significant gusts to 75 mph possible Scattered large hail events to 1.5 inches in diameter possible A tornado or two possible SUMMARY...Storms across western South Dakota and northwest Nebraska late this evening should further organize, intensify, and likely gradually accelerate east-northeastward overnight across central into eastern South Dakota. Multiple corridors of wind damage, potentially significant on a localized basis, could occur, with some hail possible as well. The severe thunderstorm watch area is approximately along and 80 statute miles north and south of a line from 30 miles north northwest of Chamberlain SD to 20 miles northeast of Brookings SD. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU4). PRECAUTIONARY/PREPAREDNESS ACTIONS...

Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0356 AM CDT Sat Aug 16 2025 Valid 191200Z - 241200Z ...DISCUSSION... ...Tuesday/Day 4 and Wednesday/Day 5... A mid-level ridge will build across the Rockies and northern High Plains during the middle part of the week. At the surface, a front will advance slowly southward into the lower Missouri and mid Mississippi Valleys. A post-frontal airmass will remain over the upper Mississippi and Great Lakes region. On the southern and western periphery of this airmass, moderate instability is forecast to develop each afternoon. Limited large-scale ascent is expected to keep convective coverage isolated. In spite of relatively weak deep-layer shear along much of the instability corridor, steep low to mid-level lapse rates will be in place and could be enough for a marginal severe threat in areas that destabilize the most. ...Thursday/Day 6 and Saturday/Day 8... Mid-level zonal flow is forecast to develop on Thursday over much of the north-central and northwestern U.S., as a ridge moves southeastward into the western Great Lakes. A pocket of moderate instability is forecast to develop ahead of a cold front on Thursday in the northern Plains. Limited large-scale ascent should keep convective coverage isolated. Although deep-layer shear is forecast to be modest, any cell that can develop and persist near the stronger instability in the late afternoon and early evening could obtain an isolated severe threat. On Friday an Saturday, a cold front is forecast to move southeastward across the north-central U.S. Near and ahead of the front, isolated thunderstorms will be possible each afternoon from the upper Mississippi Valley into the Great Lakes region. The combination of instability and shear could be sufficient for an isolated severe threat. However, considerable uncertainty exists at this range in the forecast. Read more
