850 ACUS02 KWNS 031733 SWODY2 SPC AC 031732 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1232 PM CDT Thu Jul 03 2025 Valid 041200Z - 051200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER PARTS OF THE CENTRAL AND NORTHERN PLAINS TOWARD THE UPPER MISSISSIPPI VALLEY... ...SUMMARY... Scattered strong to severe thunderstorms are expected mainly over the central to northern Plains, and perhaps late toward the upper Mississippi Valley. ...Synopsis... A trio of shortwave troughs will affect parts of the northern CONUS on Friday, with widely-scattered strong to severe storms most likely with the system moving across the Plains. This wave will lift northeastward out of the high Plains during the day, with temporary shortwave ridging over the upper MS Valley. Temperatures aloft will remain relatively warm, though some cooling will occur over the western Dakotas and NE. At the surface, a cold front will slowly develop into the western Dakotas during the day, with a trough extending southward along the CO/KS border. This front will push into NE and western MN overnight, maintaining a focus for continues storms. Southerly winds will maintain substantial low-level moisture ahead of the front with dewpoints from the mid 60s to lower 70s F contributing to moderate overall instability. ...Dakotas into MN... Storms are likely to develop near the surface trough from central NE into SD, and especially near the cold front over ND where lift will be strongest. Instability will also be stronger from ND into northern MN, and mixed storms modes may produce both damaging gusts and isolated hail. This activity will likely persist through the nigh across much of western and northern MN, with perhaps more isolated storms persisting farther south into southern MN/western IA. ...NE into western KS... Strong heating and low-level convergence within the surface trough will combine with a moist air mass and support least isolated afternoon storms from far eastern CO into western KS and vicinity. Shear will be weak, with veering winds with height supporting southeastward-propagating storms capable of locally strong gusts. ..Jewell.. 07/03/2025 $$
