An area of low clouds and fog has developed early this morning. Locally dense fog will reduce visibility 1/2 mile or less at times through mid-morning, especially along and east of the Buffalo Ridge in southwest Minnesota. Clusters of thunderstorms are expected to develop around the Highway 81 to Interstate 29 corridors in the early afternoon, moving east into southwest Minnesota through this evening. Isolated strong to severe storms are possible, with the primary threats of hail to 1.5 inches (ping pong ball size) and wind gusts to 60 mph. Locally heavy rain may also produce ponding water in urban locations and low lying areas. .DAYS TWO THROUGH SEVEN...Monday through Saturday. Additional thunderstorms are expected Monday afternoon and evening, with an Enhanced (Level 3 of 5) Risk for severe storms. Initial storms will be capable of producing golf ball size or larger hail along with isolated tornadoes. As storms evolve into line segments, the primary threat will transition to damaging wind gusts up to 65 mph with isolated embedded tornadoes. The greatest uncertainty for Monday is exactly where storms will develop and track. .SPOTTER INFORMATION STATEMENT... Spotter activation is possible between 3 pm and 10 pm today. $$ IAZ001>003-012>014-020>022-031-032-NEZ013-014-SDZ038-050-052>054- 057>071-161000- Lyon-Osceola-Dickinson-Sioux-O`Brien-Clay-Plymouth-Cherokee- Buena Vista-Woodbury-Ida-Dixon-Dakota-Beadle-Gregory-Jerauld-Sanborn- Miner-Brule-Aurora-Davison-Hanson-McCook-Minnehaha-Charles Mix- Douglas-Hutchinson-Turner-Lincoln-Bon Homme-Yankton-Union- 453 AM CDT Sun Jun 15 2025 This Hazardous Weather Outlook is for northwest Iowa, west central Iowa, northeast Nebraska, central South Dakota, east central South Dakota, south central South Dakota and southeast South Dakota. .DAY ONE...Today and tonight.
