.SYNOPSIS...
Pockets of light precipitation are expected to taper off tonight,
with light rain again tomorrow. Temperatures cool off this
weekend, with lows in the low to mid 30s. Upper level ridging is
expected late in the weekend to early next week.

&&

.SHORT TERM /TONIGHT THROUGH FRIDAY NIGHT/...
The latest forecast remains on track this evening with light
winds and areas of patchy fog. Tomorrow, expect additional
accumulations of light rain, though nothing impactful is
expected of it. Only a few tenths of an inch area wide are
expected by the end of the afternoon. Expect light northeasterly
winds throughout the day. Temperatures will be in the mid 40s.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
The weekend will feature drier weather as upper level ridging
develops offshore. Afternoon highs will dip into the low 40s
with lows in the 30s, approaching freezing by Sunday morning.
With upper level ridging in place, more widespread fog and
stratus development may be of concern into early next week. The
pattern will be monitored into next week to keep an eye on any
indication that the pattern may become more active, but for now,
it looks like a much more mild end to 2025.

.AVIATION...
VFR across the southern Puget Sound terminals this evening with
areas of MVFR to LIFR in low stratus and fog elsewhere. Light
shower activity will continue to taper off this evening, with
the next round of showers lifting northward across western
Washington Thursday morning into the afternoon. This is favored
to generate localized MVFR to IFR conditions in rain showers.
Surface winds generally southerly will decrease overnight and
shift northerly and increase to 5 to 12 kt as precipitation
moves in on Thursday.

KSEA...VFR this evening, favored to continue through the
morning. A BKN high ceiling is favored to develop overnight,
which will likely limit fog development at the terminal.
Ceilings will drop to MVFR as rain showers move northward into
the region Thursday afternoon, with south to east winds
overnight shifting north/northeast with the incoming
precipitation. Winds through the period will likely stay below
10 kt.

.MARINE...
Winds this evening have subsided, and as a result, all Small
Craft Advisory headlines for wind have been cancelled this
evening. A broad surface trough well to the south of the area,
combined with high pressure over British Columbia, will generate
a period of northerly flow over area waters into Friday. This
will likely generate a push of westerly Small Craft Advisory
winds through the Strait of Juan de Fuca. Thereafter, high
pressure will build across the waters over the weekend and into
early next week for benign conditions and light winds. Fog may
develop over area waters into early next week as a result.

Seas around 4 to 6 feet this evening will build to 10 to 13 feet
on Friday, remaining elevated before subsiding on Saturday. A
Small Craft Advisory has been issued across the coastal waters
for elevated seas. Seas are then forecast to remain below 10
feet through much of next week.

.HYDROLOGY...
