.DISCUSSION...Expect daily chances for showers and thunderstorms.
Storms will most likely initiate over the White Mountains and
push towards the Billy Fire along outflow boundaries. There is low
to moderate confidence on whether these storms actually reach the
fire, and thus the chance of precipitation is 30%. Activity will
decrease after sunset, before isolated to scattered storms pick
up again on Wednesday. The primary hazards near any storms will
be lightning, gusty outflow winds, and brief downpours.
