A cold front moving through the area today will bring a chance for showers and thunderstorms to eastern portions of the region later this afternoon into the evening hours. A Marginal to Slight risk for severe storms exists over northeastern SD into west central MN. The main threats would be hail up to around quarter size and wind gusts from 60 to 70 mph.
Plenty of western U.S. wildfire smoke aloft will remain over the region today into tonight. Although, some of this smoke may make it to the surface today into tonight as a cold front moves through the region. There may be minor visibility reductions at times, along with reduced air quality.
Northerly winds will increase across central/north central SD this afternoon and evening as a cold front moves through the region. Wind gusts from 40 to 45 mph are possible, along with humidity values from 25 to 35 percent for much of central SD. These conditions combined with dry fuels will promote high to very high fire danger. A Red Flag Warning has been issued for today.
