Severe Storms

SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0232 AM CDT Sat Aug 09 2025 Valid 111200Z - 121200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe storms are not forecast for Monday. ...Synopsis... On Monday, a weak upper trough will remain over the central US, but winds aloft are forecast to dwindle as a primary midlevel wave sweeps across the northern Plains to upper Great Lakes. A weak surface trough may remain from the southern Plains into the lower MO Valley, but lift here will remain subtle. Overall, a moist and unstable air mass will still exist, but the lack of large-scale ascent and weakening lapse rates aloft is expected to mitigate severe storm potential. That said, a corridor of strong storms is most likely during the afternoon/early evening from parts of West TX across OK, eastern KS, MO and IL, with areas of gusty winds. ..Jewell.. 08/09/2025 Read more

WW 578 SEVERE TSTM IA MN SD WI LS 090235Z - 090900Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 578 NWS Storm Prediction Center Norman OK 935 PM CDT Fri Aug 8 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Northwest Iowa Minnesota Far Eastern South Dakota Northwest Wisconsin Lake Superior * Effective this Friday night and Saturday morning from 935 PM until 400 AM CDT. * Primary threats include... Scattered damaging winds likely with isolated significant gusts to 80 mph possible Scattered large hail and isolated very large hail events to 2 inches in diameter possible A tornado or two possible SUMMARY...Severe storms are expected to develop through mid/late-evening initially across western/north-central Minnesota and possibly far east/southeast South Dakota and northwest Iowa, before moving into east/northeast Minnesota and northwest Wisconsin overnight. Large hail is possible, but damaging winds may become the most common hazard. Some tornado risk may exist as well. The severe thunderstorm watch area is approximately along and 80 statute miles east and west of a line from 55 miles northwest of Ely MN to 35 miles southwest of Worthington MN. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU8). 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. && AVIATION...A few severe thunderstorms with hail surface and aloft to 2 inches. Extreme turbulence and surface wind gusts to 70 knots. A few cumulonimbi with maximum tops to 550. Mean storm motion vector 24025. ...Guyer Read more

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0118 AM CDT Sat Aug 09 2025 Valid 101200Z - 111200Z ...Synopsis... Fire weather concerns are expected to persist across portions of the Southwest/Four Corners region through the weekend. Very dry conditions are expected to persist across the greater Great Basin and western Four Corners with another day of 5-15% RH minimums likely. Short to medium-range guidance depicts the passage of a weak mid-level trough across the central and southern Rockies through Sunday evening. While sustained surface winds are expected to remain fairly modest (generally less than 15 mph), augmented flow near the top of the boundary layer should promote frequent gusts between 20-25 mph over a region with dry fuels and active fires, resulting in periods of elevated fire weather conditions. The mid-level trough will also promote isolated to scattered thunderstorms from southern AZ to eastern NM. While thunderstorm coverage and intensity is expected to be greatest across NM, more isolated convection developing along and north of the Mogollon Rim should reside in a dry/deeply-mixed environment favorable for dry lightning strikes. ..Moore.. 08/09/2025 ...Please see www.spc.noaa.gov/fire for graphic product...
