.DISCUSSION...

Mostly cloudy skies this morning will dissipate late this
morning, leading to mostly sunny skies this afternoon as a trough
of low pressure quickly moves through the region today. There is a
very small chance for a rain shower with this trough, but no
measurable precipitation is expected. Winds will remain from the
north to northwesterly directions, with gusts between 10 to 20
mph possible at the burn site. Minimum humidities will fall into
the middle 20 percent range, but could fall to the lower 20
percent range if the clouds move out faster than expected.

High pressure will build into the region tonight, leading to clear
skies, light winds, and colder temperatures. Lows overnight will
dip into the middle 20s at the burn site.
