Snow (mixed with rain southwest to south-central South Dakota) will overspread much of the area today, moving west to east, and sinking slowly southward. Snow will end overnight tonight. The highest snow amounts will occur for the northern Black Hills. Locally higher amounts may occur across northwestern South Dakota due to banded snow. Confidence is high that it will precipitate. Confidence is medium for snow amounts for the Black Hills and low on the plains. This is largely due to marginally cold temperatures limiting snow accumulation with much of the snow falling during the day when temperatures are warmer. PRECAUTIONS: Use caution while traveling. Be prepared for rapidly changing visibilities.
