area forecast discussion
national weather service seattle wa
906 pm pdt Thu apr 25 2019

Synopsis After one more dry day Friday, an upper trough will
bring a chance of showers and cooler weather to the region Friday
night and Saturday. Sunday looks dry, but another upper trough will
remain near the region and could bring scattered showers each day
next week.

Short term tonight through Sunday A weak upper level trough
will cross the area tonight but the forecast is mostly dry. No
changes from the previous forecast. 33
previous discussion... Increasing low level onshore flow Friday
will cool temperatures a few degrees, with highs in the mid 50s to
low 60s.

Strong onshore flow will bring westerly gales to the strait Friday
night and will also bring considerable cloudiness. A second upper
trough will cross the area on Saturday. This should bring a more
widespread chance of showers to the area. The cascades will have the
best chance for showers. The snow level will fall to 3000 feet or
lower, and a few inches of snow will probably fall in stevens and
snoqualmie passes. A convergence zone pattern is evident in some
models, so seattle could remain cloudy and showery most of the
day. Highs Saturday will be in the 50s.

Dry northerly flow on Sunday will clear the clouds and allow
temperatures to rebound into the low to mid 60s. Some residual
showers will still be possible in the mountains. Burke

Long term Monday through Thursday Previous discussion... A
longwave upper trough will remain around the region all through
next week. Each day will have a chance of showers, sometimes in
the mountains only, sometimes over the lowlands as well. Tuesday
and Wednesday look like the drier days. High temperatures will be
in the low to mid 60s each day. Burke

Aviation An weak upper level trough will cross the region
tonight although mainly dry weather is expected. Onshore flow will
increase Friday afternoon for gusty westerly winds. May see patchy
low clouds Friday morning (coast and SW interior), otherwiseVFR
conditions expected. 33
ksea...VFR conditions tonight. Winds becoming S SW 12-15z and
increasing to 10-15 kt by 18z. 33

Marine High pressure over the NE pacific will give N NW flow
over western wa tonight. Strong onshore flow will develop on
Friday with gales possible through the strait of juan de fuca and
small craft advisory winds elsewhere. Onshore flow will ease on
Saturday. Northerly flow will develop on Sunday. 33

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
