.DISCUSSION...Drier air begins to work in Thursday, limiting shower
and thunderstorm chances to the higher terrain adjacent to the fire
location. These storms could produce outflows that reach the fire in
the later afternoon or early evening, resulting in gusty and erratic
winds. Temperatures will steadily increase through the weekend, and
daytime minimum humidity values will begin to drop into the teens.
Winds remain light through the period, meaning critical fire weather
conditions are not expected.
