AREA FORECAST DISCUSSION
National Weather Service Eureka CA
137 PM PDT Sat Jul 26 2025

.SYNOPSIS...Thunderstorm chances drop off for the weekend. Near
normal to slightly below normal temperatures expected into early
next week. Temperatures trend slightly upward towards the later
parts of next week.


&&

.DISCUSSION...The upper low that brought convection to mostly
Trinity County on Friday moves to the east Saturday, taking most
mid-level moisture with it. As a result, thunderstorm chances
significantly decline into the weekend; however, isolated
thunderstorms could still occur in the afternoon to evening hours
in the Trinity Horn region both Saturday and Sunday with chances
significantly less on Sunday.

Late this weekend and into the middle of next week, high pressure
is expected to generally remain east of the area. This will keep
temperatures near seasonal normals with highs in the upper 80s to
low 90s. Coastal stratus is expected to form each night during
this time with the potential for some clearing into the
afternoons. Thunder potential generally looks to remain low.
Ensembles are hinting at another upper-low forming right off the
coast, which may return thunderstorm chances by mid next week.
This thunderstorm potential will be monitored.


&&

.AVIATION...(18Z TAFs) IFR conditions are clearing to MVFR (and
potentially VFR) conditions through the morning. An upper level
trough will increase mixing allowing ceilings to lift and scatter
through the daylight hours.  Light winds are expected today as
coastal eddies spin keeping winds variable. The upper level
trough will keep the marine layer deep and moist through the night
allowing for IFR conditions to return to the coastal areas and
river valleys. Inland, fog is currently evaporating and will give
way to VFR conditions with light winds through the day. In Trinity
County, there is about a 10-20% chance for Thunderstorms this
afternoon with potential dangerous downburst winds up to 40kts and
heavy rain.


&&

.MARINE...A weak pressure gradient between an offshore ridge and
an inland trough will keep winds gentle to moderate through the
weekend. Northerlies will accelerate around Cape Mendocino and
result in a narrow band of gusts around 25 kt through Saturday. Seas
around 3 to 5 feet are expected, with the lowest waves expected
nearest the coast. The sea state will be dominated by 2 to 5 foot
wind waves and a small long period southerly swell. Northerly winds
are forecast to increase early to mid next week to fresh breezes
over the outer waters and in the lee of Cape Mendocino.

.EKA WATCHES/WARNINGS/ADVISORIES...
