AREA FORECAST DISCUSSION
National Weather Service Eureka CA
1216 AM PDT Sun Jul 27 2025

.SYNOPSIS...Thunderstorm chances remain for Sunday afternoon.
Near normal to slightly below normal temperatures expected into
early this coming week. Another upper low could bring chances for
thunderstorms mid week.


&&

.DISCUSSION...Some mid-level moisture remains in the area making
isolated thunderstorms possible for Sunday afternoon to evening in
the Trinity Horn region. Chances of thunderstorms are less than
25%. Chances drop off for early this 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 this coming
week. This thunderstorm potential will be monitored as the threat
approaches.



&&

.AVIATION...27/06Z TAFS, ceilings around 500-800 feet over coastal
terminals tonight and Sunday morning are expected to dissipate by
late morning into early Sunday afternoon in response to daytime
heating and mixing. Onshore flow remains weak, but expect stratus to
reform over North Coast terminals Sunday evening. Now, along the
Mendocino coast, small scale eddy circulations may keep low clouds
and IFR conditions locked-in along the shoreline through the day.

Inland, VFR conditions are expected to prevail tonight and Sunday.
Some low clouds and IFR conditions in the coastal river valleys will
dissipate quickly by mid morning Sunday. Also, deep cumulus
convection is forecast for Trinity County during the afternoon and
evening Sunday. Moderate turbulence and low level shear, gusty
outflow winds and heavy precip rates will also be possible in and
around thunderstorms.


&&

.MARINE...A weak pressure gradient between an offshore ridge and
an inland trough will continue to maintain a gentle to moderate wind
regime through Sunday. Stronger winds with gusts to 25-30kt are
likely in the lee of Cape Mendocino. Seas are forecast to remain low
and dominated by 2 to 5 foot wind waves and a 1 to 2 foot long
period southerly swell. Highest wind waves will remain over the
outer waters and in the lee of Cape Mendocino. Northerlies are
forecast to increase next week, strongest over the outer waters and
downwind of Cape Mendocino.
