.DISCUSSION...
High pressure aloft building into Montana from the west will
gradually decrease the northwesterly flow aloft over the fire area
through Thursday. This will keep the area mostly sunny with
gradually decreasing northwesterly surface winds and gradually
warming temperatures. This will also result in afternoon humidity
falling into the 15 to 25 percent range. The dry conditions are
forecast to continue through Saturday under the high pressure ridge,
but the light winds will shift more northerly on Friday behind a
weak Canadian cold front passage, then more easterly on Saturday.
The next chance for showers and possibly a few thunderstorms will
be Sunday evening into Monday.
