Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0324 AM CDT Sun Aug 10 2025 Valid 131200Z - 181200Z ...DISCUSSION... From Wednesday/D4 into Thursday/D5, a shortwave trough is forecast to move from the Pacific Northwest across MT and over the far northern Plains, with an upper speed max developing into southern SK and MB. In advance of this trough, a leading trough affecting the Great Lakes region will also lift northeastward, with height rises and a warming pattern across parts of the Plains and upper Midwest. The combination of increasing dewpoints and the upper trough glancing the region may result in some manner of severe risk late Thursday/D5, and most likely from parts of ND into northern MN, and in evening/overnight MCS form. Future model trends will be monitored for a possible risk area. From Friday/D6 onward, predictability decreases with the motion of the aforementioned upper wave. However, large instability is likely to again build across the Mid MO/Upper MS Valleys, and at least sporadic severe storms cannot be ruled out from the northern High Plains eastward toward the Upper Great Lakes.

URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 582 NWS Storm Prediction Center Norman OK 845 PM CDT Sat Aug 9 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Southwest Iowa Western and Northern Kansas Southern Nebraska * Effective this Saturday night and Sunday morning from 845 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...Clusters of storms across far eastern Colorado/northwest Kansas/southwest Nebraska as of mid-evening (845 pm CDT) will likely continue to spread eastward and organize, potentially into a bowing linear complex. Other storms may develop ahead (east) of it and also intensify within a very unstable air mass. Damaging winds and occasional large hail are the primary severe hazards expected across the region. The severe thunderstorm watch area is approximately along and 70 statute miles north and south of a line from 95 miles west southwest of Hill City KS to 40 miles south southeast of Omaha NE. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU2). 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 581... AVIATION...A few severe thunderstorms with hail surface and aloft to 2 inches.

SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0220 AM CDT Sun Aug 10 2025 Valid 121200Z - 131200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe storms are not forecast for Tuesday. ...Synopsis and Discussion... A shortwave trough will move out of the upper MS Valley and into the Upper Great Lakes on Tuesday, with a weak/residual midlevel trough over the central Plains. A weakening cold front attendant to the northern trough will push south across MN, WI and IA late with drying as the surface low pulls well north of the area. Otherwise, a weak surface pattern will exist from the Plains to the East Coast, but with a persistently moist air mass. Scattered thunderstorms appear most likely from IN southwestward into OK, however, shear will remain weak across the entire area, and lapse rates aloft will not be very steep. As such, mostly general thunderstorms are expected. ..Jewell.. 08/10/2025 Read more
