.DISCUSSION...
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.
