Sioux Falls, SD
Areas of dense fog have developed across parts of SW MN and NW IA this morning. That fog will lift during the day with highs returning to the upper 70s and lower 80s under partly cloudy skies. It won’t be too breezy either, with a south wind at 5-15 mph in most areas. That will change in a big way starting tonight.
A high wind watch is in effect for much of northern KELOLAND late tonight and tomorrow. Northwest winds could gust over 50mph behind a very strong cold front during the day. Areas of clouds and showers will accompany this system overnight and tomorrow morning.
Cool weather will continue on Wednesday and Thursday with highs mainly in the lower to middle 60s. We do see a big warming trend late in the week with highs returning to the 70s and 80s by next weekend.
