Anticipate a periodically wet period over the next week with
multiple areas of enhanced moisture potentially contributing to
increased rainfall slated to spread statewide under a developing
and lingering upper weakness/trough. Moisture seems associated
with Felicia today and more uncertainly from Guillermo early next
week. Toward Wednesday-Thursday, guidance still varies for another
area of moisture that could reach the state associated with a
disturbance being monitored by the National Hurricane Center over
the tropical Pacific near 122W. High pressure bridging to the
north of the state suggests moderate to brisk mean trades over the
next week may focus rainfall over windward terrain. Overall, a
model and ensemble composite seems reasonable for these systems in
a pattern with lowered predictability.
