WW 560 SEVERE TSTM IA NE 300245Z - 300900Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 560 NWS Storm Prediction Center Norman OK 945 PM CDT Tue Jul 29 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Far Southwest Iowa East-Central and Far Southeast Nebraska * Effective this Tuesday night and Wednesday morning from 945 PM until 400 AM CDT. * Primary threats include... Scattered damaging wind gusts to 70 mph possible Isolated large hail events to 1 inch in diameter possible SUMMARY...Ongoing convective line is expected to continue southeastward, perhaps even turning a bit more south-southeastward, into east-central/southeast Nebraska and far southwest Iowa this evening. Strong to severe gusts will remain possible with this line as it moves through the region. The severe thunderstorm watch area is approximately along and 60 statute miles east and west of a line from 35 miles northeast of Columbus NE to 15 miles southwest of Shenandoah IA. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU0). 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 556...WW 557...WW 558...WW 559... AVIATION...A few severe thunderstorms with hail surface and aloft to 1 inch. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 32035. ...Mosier Read more

SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0228 AM CDT Wed Jul 30 2025 Valid 011200Z - 021200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... No severe thunderstorms are anticipated on Friday. ...Discussion... A mid-level ridge will remain centered across the High Plains on Friday with a sharpening mid-level trough advancing southeast across the Northeast. At the surface, a front will extend from the Mid-Atlantic to central Texas. Shear is forecast to remain very weak south of this frontal zone. This weak shear, combined with weak mid-level lapse rates, should limit overall storm organization. Thunderstorms are expected to develop across the Rockies on Friday and eventually spread into the adjacent Plains where greater instability is present. Isolated stronger storms capable of marginally severe hail and severe wind gusts could be possible. At this time, it unclear how many strong storms may develop across northern Colorado and southeast Wyoming. This uncertainty, combined with weaker shear than D2/Friday, precludes a Marginal Risk addition at this time. ..Bentley.. 07/30/2025 Read more

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0206 AM CDT Wed Jul 30 2025 Valid 311200Z - 011200Z ...Synopsis... A mid-level trough, with embedded impulses, will linger along the West Coast as upper ridging persists across the central and eastern U.S. tomorrow (Thursday). Mid-level perturbations pivoting around the West Coast upper trough will encourage widespread 15-20 mph sustained southwesterly surface winds amid 15-20 percent RH across much of the Great Basin. Since these conditions will overspread dry fuels, Elevated highlights have been introduced. As a mid-level impulse gradually drifts northward across the Pacific Northwest, scattered thunderstorms will develop atop a dry boundary layer and dry fuels. However, PWATs may be higher compared to previous days, suggesting a potential mix of wet and dry thunderstorms. While isolated dry thunderstorm highlights have been introduced, consideration was also given for introducing Scattered dry thunderstorm highlights. However, the possibility for several storms producing wetting rains, and the potential for widespread stability to overspread the Pacific Northwest due to high-density thunderstorm coverage from Day 1, precludes greater highlights at this time. ..Squitieri.. 07/30/2025 ...Please see www.spc.noaa.gov/fire for graphic product...
