.DISCUSSION...
As an upper trough makes its presence known, relative humidity is
expected to remain above 30 percent through Saturday,
temperatures will be a bit below average, and rainfall between 0.2
and 1.4 inches are part of the story through Friday night.
Although isolated thunderstorms are in the forecast, there is
still moderate to high confidence of fire weather remaining below
the critical mark.
