.DISCUSSION...Warmer and drier conditions will peak today as offshore
flow promotes additional drying over the Cascades and a thermal
trough shifts inland. Onshore flow will resume on Monday, bringing a
return to seasonable conditions through next week. Chances for rain
begin to increase by next Friday, though confidence over widespread
wetting rains remains low.
Forecast for 20 foot wind speed (valleys and ridge tops) are 10
minute averages reflecting RAWS winds.
