Synopsis Temperatures will slowly rebound on Thursday, with
enough moisture and instability for a few afternoon showers and
thunderstorms over the cascades. A warm and dry upper ridge axis off
the coast on Friday will pass directly over western washington on
Saturday. Its warm and dry influence will continue from Sunday
through Tuesday, including memorial day.

Short term Northerly flow aloft will prevail until late
Friday. A disturbance will dive down out of interior b.C. Into
central washington on Thursday, bringing colder air aloft and a
cyclonic turn to the upper flow. The main meteorological impact
will be to steepen low- mid level lapse rates and give rise to
convective instability over the mountains, more notably the
cascades. CAPE values will peak around 400-600 j kg over the
cascades, and northerly mid- level speed shear will enhance lift
and aid some loose organization. So looking for a few late
afternoon and early evening showers and thunderstorms over the
cascades on Thursday pm.

A well-amplified upper ridge axis will pass east across 130w on
Friday. Upper heights will rise quickly over the pac nw, and the
cooling low-level onshore flow component will weaken further.

These things will all support a hearty day-over-day rise in
afternoon temperatures and a dry forecast on Friday.

The upper ridge axis will pass directly over western washington on
Saturday. Haner

Long term The upper ridge axis will move to eastern washington
on Sunday and then stay in place there until Tuesday. The turn to
a mid-upper level southerly flow component will start to support
a couple of afternoon showers and thunderstorms near the cascade
crest each afternoon and evening from Sunday through at least
Tuesday. Seabreezes along the immediate coast will hold afternoon
highs in the 60s there, but inland temperatures will be well above
normal each day.

By next Wednesday, it appears the upper ridge axis to our east
will flatten, with a more zonal flow pattern trying to develop.

Cooling onshore flow will spread further inland, but afternoon
temperatures will still remain above normal. The operational gfs
was cooler than most of its ensembles next wed. Haner

Aviation Northerly flow aloft will prevail tonight and
Thursday with an upper ridge offshore and an upper trough inland.

At the surface, onshore flow will gradually ease with high
pressure offshore and lower pressure inland. The air mass is
stable with areas of low and mid level moisture. The low and mid
levels are expected to dry somewhat tonight but some MVFR low
clouds will probably linger or reform near the coast.

Ksea... Mid clouds are expected to break up this evening.

Northerly wind 5-10 knots will become light after midnight
tonight. Schneider

Marine High pressure will be offshore with lower pressure
inland tonight. Small craft advisory westerly winds over the
coastal waters and strait of juan de fuca will end tonight or
Thursday morning as onshore flow eases. A relatively short period
swell around 10 feet over the coastal waters will also gradually
subside tonight and Thursday morning.

Onshore flow will continue for the next few days but gradually
weaken and turn a bit more northerly by this weekend as a weak
thermal trough develops to the south. Schneider

Sew watches warnings advisories
Wa... None.

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.
