What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis Coastal stratus will return to the area today and
continue into the middle of the coming week with partial sun
expected each afternoon. Over inland areas, there is a slight
chance for afternoon showers and thunderstorms over the trinity
alps and yolla bolla this afternoon and evening. After near normal
temperatures this weekend, inland temperatures will return to
above normal by the middle of the coming week.

Discussion A large upper low continues to spin well E of the
area with moisture and instability rotating around the back side
of the feature. This is producing scattered shower activity over
portions of trinity county and the yolla bollys this afternoon.

Dynamic support for convection has waned since yesterday, but
there are still pockets of positive vorticity advection helping to
force today's convection. So far, no lightning has been detected
with this activity and expect strikes will be few and far between
later today, mainly to the E of our area. Nevertheless, have
continued isolated thunder over portions of E trinity county into
the early evening hours.

Coastal stratus has been creeping up the coast from the S as
expected today. During the past couple of hours, a streamer of
stratus has shot nne toward the lower redwood coast as S return
flow rounds CAPE mendocino. Expect skies along the coast will vary
between partly and mostly cloudy for the rest of the afternoon.

Clouds should then thicken this evening as daytime heating over
land comes to an end. There may be a period of drizzle this
evening along the redwood coast as models continue to indicate
increasing low-level moisture flux convergence, but this area
should continue to spread nnw away from the coast later in the
night. Low clouds are expected to linger along the pacific coast
through about mid-week. However, clouds should erode nicely over
land with daytime heating.

Warmer conditions are expected this week as the upper trough
shifts E and high pressure builds along the coast. High
temperatures may reach the century mark across portions of the s
interior as we get to the end of the work week and into next
weekend. Daytime humidity values look fairly dry at this time,
with minimal heat impacts. Sec

Aviation Return flow continues to make its way up the coast,
and, with it, coastal stratus. Clouds will vary from scattered to
broken along the redwood coast for the remainder of the afternoon,
with more consistent and lower ceilings later this evening and
overnight. A few patches of drizzle are possible this evening,
mainly near and S of kacv. Winds will become more southerly, and,
after an initial gustiness, begin to decrease in speed. As
ceilings lower along the coast, some fog is likely. There is
considerable uncertainty regarding exactly how low the ceilings
and visibilities will drop, but ifr conditions are expected. Some
cloudiness may make its way into kuki late tonight, but it will
probably have to make its way from the W instead of the s, and the
marine layer may not be quite deep enough for the moisture to make
it over the coastal terrain. Sec

Marine Winds and seas will slowly settle through the evening,
although this process will take longer across the waters north of
cape mendocino as northerly winds will subside more gradually
here.

In areas near the coast, a surge of light to moderate southerly
winds will continue to creep northwards this evening and tonight.

Winds and seas will continue to subside into Monday. This will
also likely bring a renewed surge of marine stratus and fog.

Northerly winds will return Monday night and will steadily
increase through the end of the week. By Thursday, additional
small craft advisories will likely be warranted, and gale force
winds will be possible Friday and beyond. Brc tn
