.SYNOPSIS...
The strong low pressure system is making its way into the
Cascades. Winds have been strong this afternoon, but are on the
way down in the Puget Sound area. Elevated winds will continue
through the Strait of Juan de Fuca tonight. Drier conditions are
forecast for the weekend, with a return to unsettled weather
early in the week.
&&
.SHORT TERM /TONIGHT THROUGH SUNDAY NIGHT/...
The low pressure system has pushed east this evening. Scattered
moderate to heavy showers still continues to move across the region
and will subside into the overnight hours. Lightning still remains
possible with these storms. The Wind Advisories have been allowed to
expire as well. Conditions remain breezy across the Strait of Juan
de Fuca and will continue to subside tonight.
Due to the strong winds, there are a number of power outages being
reported in the region, as well as debris on area roadways. Exercise
caution navigating the region this evening with these hazards and
outages in place. Preliminary wind gust reports show speeds as high
as 58 mph on the coast near Westport and 38 mph for Sea-Tac airport
today.
Cloudy and cool, though drier weather is expected tomorrow.
Highs will struggle to get much above the low 60s. Morning lows will
be in the upper 30s in the Cascade foothills and 40s throughout the
Sound. More sun is expected on Sunday, but temperatures will remain
the same.
21/29

.LONG TERM /MONDAY THROUGH FRIDAY/...
Zonal flow aloft will allow an additional system to drop into
the area Monday evening into Tuesday for renewed chances of rain
and breezy conditions. The models aren`t exactly sure what to do
with the middle of the week, though there is still some
semblance of convergence on zonal flow to weak ridging for that
time frame. Additional unsettled weather seems possible late in
the week as broad troughing returns to the eastern Pacific, as
indicated in the longer range ensemble analysis. Highs will be
in the low to mid 60s throughout the week.
