AREA FORECAST DISCUSSION

1041 PM PDT Wed May 21 2025

.SYNOPSIS...Slight chance of drizzle along the north coast Thursday
morning. Upper level disturbances for the rest of this week and
weekend will bring cooling temperatures. Another period of warm
temperatures and high pressure this weekend before and another
chance for light rain Sunday into Monday.


&&

.DISCUSSION...Breezy northwesterly winds will continue to diminish
overnight. Cloud cover will increase along the north coast overnight
into Thursday as an upper shortwave and weak surface low clips
northern California. HREF indicating 20 to 30% chance of drizzle in
far northern Del Norte County, 10 to 20% along the northern Humboldt
coast.

Thursday and Friday broad/weak troughing will drift by to
our north, but will not have much more effect than mid level cloud
cover and cooler temperatures, especially in interior valleys.
Chance of isolated thunder Friday afternoon is becoming less and
less likely for eastern Trinity county with minimal moisture
available to initiate convection. High amplitude ridging expected to
return Saturday and Sunday, allowing temperatures to briefly rebound
into the 70`s and 80`s. Long range models becoming more confident
in another upper trough and surface frontal system clipping the
region late Sunday into Monday. NBM indicates 30 to 40%
probabilities for >0.01 inches, especially Monday morning.





&&

.AVIATION...VFR conditions currently exist at the TAF sites. A
stray shower or two may impact CEC overnight or in the early
morning hours on Thursday along with mid level cloud cover. MVFR
ceilings will be possible in the CEC and ACV area Thursday morning
as moisture from the passing system lingers over Northwest
California. Ceilings will improve and clear later in the day into
Thursday night as coastal north winds once again increase. /RPA



&&

.MARINE...A passing system will bring a weaker pressure gradient to
the waters over the next 18-24 hours. This will result in lighter
north winds and a decaying sea state. Winds will increase again
as high pressure builds back over the Pacific Thursday night into
Friday with small craft winds and seas possible in the southern
waters. Another weak system will approach the region over the
weekend allowing winds to decrease again and possibly even turn
out of the south briefly in the northern waters on Sunday. /RPA


&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...
None.
NORTHWEST CALIFORNIA COASTAL WATERS...
     Small Craft Advisory until 3 AM PDT Thursday for PZZ455-475.
