High pressure to the north will lead to light and variable winds across much of the region, but do expect a more consistent wind near the South Dakota Border due to daytime mixing of winds aloft with slightly stronger winds aloft. With that said, winds could still be light and variable at times, but the probability for that at your burn site is very low. Anticipate wind direction to fluctuate between north and northeast around 10 mph by early afternoon. Sunny today (some smoke) with afternoon humidity in the mid 20s, with a lower probability of lower 20s. .REST OF TODAY... Sky/weather.........Sunny (5-15 percent). Patchy smoke.
