.DISCUSSION...

Light northeast wind and poor smoke dispersion through 8 AM. Winds
will increase through the morning. Smoke dispersion improves by
mid day with winds sustained 10 to 15 mph with occasional afternoon
gusts up to 20 mph. Latest high resolution models suggest areas
of smoke from Canadian wildfires will filter through aloft and may
reach the surface across southeast South Dakota tonight, lingering
through the day Monday. Upstream observations with visibility as
low as 4 miles has been observed in this near surface smoke.

Temperatures, initially starting in the lower 50s, will warm to
the mid 70s with an afternoon minimum humidity around 30 percent.
The next chance of rain comes Tuesday night.
