.DISCUSSION...Critical fire weather conditions are not expected 
through the seven-day forecast. A surge of tropical moisture from
decaying Pacific storms moves into the region this weekend and
will be capable of producing widespread wetting rains and windy
conditions, especially over the higher terrain. Wet weather looks
to continue into the week ahead, with increasing chances for
mountain snow by midweek.
