AREA FORECAST DISCUSSION
National Weather Service Eureka CA
257 PM PDT Thu May 9 2024

.SYNOPSIS...A Pacific ridge of high pressure will continue to
bring warm temperatures through Saturday. This combination of
elements will allow for unseasonably warm and possibly record high
temperatures closer to the coast on Friday, but the coast is
expected to be back closer to normal for the weekend. A cooling
trend is expected for Sunday and Monday with hot temperatures
returning for the middle of the week.

&&

.DISCUSSION...High pressure and offshore flow have brought clear
skies and dry conditions. This offshore flow brought warm
temperatures to the coast with KEKA reaching 69 degrees and KACV
reaching 75 degrees. KEKA has fallen short of the record high for
the date of 73 degrees. Tonight skies are expected to remain clear
for the most part, although some patchy ground fog is possible
along the coast with the lighter winds tonight. Frost is not
expected again tonight. Winds will be lighter, but it is 5 to 10
degrees warmer than yesterday this afternoon and it will likely
have trouble falling into the mid 30s in all but the very coldest
spots. Another warm day is expected Friday. Most areas will likely
be a few degrees warmer than today and winds may be slightly
weaker.

Friday night into Saturday the upper level ridge is starting to
flatten. With this models are showing a southerly surge south of
Cape Mendocino. This is expected to bring some stratus with it,
although the models aren`t showing that too much yet.
Temperatures will likely cool at the coast and the near coastal
areas and remain in the 60s. Farther inland temperatures will
remain similar to Friday. Saturday night into Sunday the trough
moves closer and a more widespread and deeper marine layer is
expected by Sunday morning. This may bring some drizzle to the
coastal areas. Inland areas are expected to drop down into the low
to mid 80s. A shower or two is possible over the higher terrain
of eastern Trinity county. Thunder potential remains around a 5 to
10 percent chance so have removed that from the forecast. This
will need to be monitored as it gets closer.

Tuesday and Wednesday high pressure is expected to build back
into the area with highs returning to around 90 in the inland
areas and this may also come with offshore flow to keep the
coastal areas clear. Breezy north winds are expected as well. MKK

.AVIATION...VFR conditions prevailed across northwest California
airfields today with breezy afternoon winds. VFR conditions should
persist through the remainder of the TAF period with some minor
visibility reductions from haze possible, especially along the
coast. Otherwise expect winds to decrease after sunset and become
light and variable overnight. KMZ

&&

.MARINE...North winds and steeper waves will continue to ease through
tonight. Small craft advisories were extended through 9 PM tonight
across the northern waters as afternoon buoy observations were still
showing steep waves reaching advisory level thresholds. Then mild
marine conditions will develop Friday through Saturday with moderate
afternoon northerly winds and some small northwest and south swell
systems. Conditions begin to change on Sunday as north winds
increase again with gales possible early next week. KMZ
