.DISCUSSION...
For the Kasota Prairie SNA - East, the main uncertainty is the wind
direction. Winds should be primarily out of the north at around
10 mph, but since speeds are light the direction could vary a
little east or west of north at times.

Temperatures will climb into the lower 70s which will help lower
RH values to near 25 percent by this afternoon. Otherwise
expect filtered sunshine from hazy wildfire smoke to linger
through tonight.
