AREA FORECAST DISCUSSION

.SYNOPSIS...Warm and dry conditions will continue across the
interior through the weekend. Coastal areas can expect overnight
and morning cloudiness the next few days with partial clearing in
the afternoons. A cooling trend is expected next week.
.DISCUSSION...Low clouds cover the coastal waters this morning
along with adjacent land areas up to around 2k feet (the top of
the deeper marine layer). Light S flow continues over the coastal
waters, and this should continue to support cloud cover over the
ocean and coastline. Over inland areas, clouds will once again
erode from the E. The clouds may hold in longer than previous days
since daytime heating will take longer to eat away at the cloud
cover. Due to the deeper marine layer, ceilings are higher and
there is less fog than previous mornings.
Generally dry weather is expected through early to middle part of
next week, although a bit of nighttime and morning drizzle is
possible along the coast where orographic lifting occurs.
Models continue to indicate increasing rain chances over the N
portion of the area from mid to late week next week as an upper
trough digs over the E Pacific. The models are in good agreement
with the height fields but differ a bit regarding the precip
field. The GFS if more bullish with PoPs while the ECMWF shifts
most of the precip N of the area. Have roughly 20% PoPs indicated
N of Cape Mendocino for late next week. Early indications are that
instability will preclude thunderstorm development. Another effect
of the developing trough will be a downward trend in temperatures
next week with readings falling to near to slightly below normal
by Monday or Tuesday. /SEC
.AVIATION...MVFR to IFR conditions and light winds to calm conditions will
continue at KCEC and KACV through this morning primarily due to reduced ceilings.
MVFR conditions and light winds will prevail at KCEC and KACV this afternoon
as ceilings increase. MVFR to IFR conditions and light winds to calm conditions
will prevail at KCEC and KACV overnight tonight due to stratus and/or fog reducing
ceilings and/or visibilities. VFR conditions and light winds to calm conditions
will continue at KUKI through Sunday with the exception of lower ceilings during
the early mornings today and Sunday.
.MARINE...A weak pressure gradient will persist across the region most of this
next week. Therefore light winds and low seas will persist across the waters
through the middle of this next week. Winds will increase slightly Tuesday and
Wednesday primarily across the southern outer waters.
NORTHWEST CALIFORNIA COASTAL WATERS...None.
