Key Messages
- Low stratus will continue into Saturday. Peaks of sunshine are possible Friday afternoon, but will do little to impact high temperatures.
- Low confidence (<25% probability) of low stratus/fog impacting visibility overnight. Low areas and river valleys may briefly see a reduction in visibility to less than 1 mile.
- Overnight lows will be slightly warmer than previously forecasted, limiting the area likely to see a hard freeze to along and north of Highway 14 in eastern South Dakota. Most will see lows range between 29-30 deg F.
- An extended period of dry weather is likely through most of next week as temperatures rise back above normal.
