South Dakota – Headlights glow through a blanket of fog across Sioux Falls this morning, with visibility shrinking to around four miles in misty pockets. Damp pavement and gray skies greet early commuters, but bigger weather changes are already lining up across eastern South Dakota.
According to the National Weather Service in Sioux Falls, patchy fog will fade through late morning as southeast winds increase. Temperatures rise quickly into the low 60s, bringing mild March air across Minnehaha and Lincoln counties. Gusts near 25 mph may ripple across open fields and highways like I-29 and I-90 during the afternoon.
Clouds thicken late in the day as a Plains storm system lifts north. Rain chances increase toward evening, with precipitation becoming widespread later tonight. Periods of rain may linger into early Friday, creating slick road conditions during the morning drive across Sioux Falls, Brandon, and Harrisburg.
The system strengthens Friday afternoon. Rain remains likely through much of the day with temperatures near 58°F. Meteorologists say colder air arrives quickly by evening, allowing rain to mix with snow and eventually change to wet snow Friday night. While major accumulation looks unlikely in town, bursts of snow could briefly reduce visibility and create slushy roads.
Conditions improve Saturday as clouds break and sunshine returns. Highs stay cooler near the mid-40s, but calmer winds bring a quieter pattern.
Sunday brings a brighter spring feel with mostly sunny skies and highs climbing into the mid-60s. Early Sunday morning also marks the start of Daylight Saving Time, when clocks jump ahead one hour at 2 a.m.
Longer daylight and a gradual warming trend continue into early next week. Highs reach the mid-60s again Monday, hinting that early spring warmth is slowly gaining ground across the northern Plains.
Traveling later today or Friday? Watch for wet roads and changing visibility. What conditions are you seeing where you live?
