.DISCUSSION...Generally low fire weather concerns as onshore flow prevails
into next week, promoting average temperatures and good overnight humidity
recoveries. Shower chances will be a bit higher on Sunday (20-30%). Can`t
rule out a few lightning strikes (10-20% chance of thunder) along the crest
in the afternoon, but mostly expect any thunderstorm activity to remain off
to the east. Trending drier on Monday with no rain showers or thunderstorms
expected. Minimum humidity values still only in the 40s. Northwest winds
increasing to 5 to 10 mph each afternoon, with a few gusts as high as 15 mph
possible on ridges and over exposed terrain.
