.DISCUSSION...

A mostly sunny morning gives way to developing clouds over the
Bighorn Range to the west of the fire site by early Sunday
afternoon. There is a 20 percent chance of showers and
thunderstorms between 1330 and 1700. As for wind, the primary
hazard would gusty and erratic outflow wind 15 to 30 mph from
the showers and storms. Drier air arrives from the west by early
Sunday evening leading to decreasing cloud cover. A few clouds
drift overhead late tonight and Monday morning, otherwise Monday
looks mostly sunny, warm, and dry. This trend continues through
the week.
