215 am pdt Wed may 22 2019

Synopsis Dry weather the next two days outside of
afternoon evening showers and thunderstorms over the mountains.

The next system will arrive Friday into early Saturday bringing a
chance for showers. Dry weather for the rest of the weekend into
early next week in the lowlands with mountain showers.

Short term today through Friday Upper level low has pushed
into norcal this morning with high pressure building into the area
for the next few days. Morning fog clouds possible each morning,
mainly along the coast and portions of the southwest interior.

This will gave way to mostly sunny days today and Thursday in the
lowlands. Some diurnally-driven afternoon and evening showers are
possible in the mountains with enough instability to suggest a
thunderstorm or two, especially near the cascades crest. Daytime
highs will warm into the 70s with Thursday a few degrees warmer
than today.

Shortwave will drop south from bc on Friday and then into western
oregon by Saturday. This will bring a chance for more widespread
showers across the area, but still doesn't look like it will
amount to much. Will continue to monitor the chances for
thunderstorms as low closes off overhead. Temperatures will cool
back into the 60s. Ceo

Long term Saturday through Tuesday System exits on Saturday
with high pressure then building back in for the rest of the
weekend. Will continue to see the chance for afternoon evening
showers and possible thunderstorms in the mountains each day. By
Sunday, large model differences remain with flip-flopping from run
to run. The ECMWF now drops another low down the west coast for
the start of next week while GFS holds onto ridging. Have held
onto mostly dry forecast until details become clearer. Ceo

Aviation Northeasterly flow aloft today. Some moisture will
linger although the trend is for drying conditions with clearing
skies. CIGS over W wa generallyVFR except for hqm with ifr
conditions there. Some low level moisture... Particularly in
locations more prone to lower CIGS such as in the SW interior... May
allow for momentary MVFR or ifr conditions overnight. Expect mostly
dry weather today and into Thursday as weak high pressure moves in.

Ksea...VFR ceilings will prevail. Variable wind 3-6 kt this
morning before becoming northerly 8-12 kt by afternoon. Smr

Marine Winds fairly benign this morning... Although SCA winds will
remain in place over the outer coastal waters over the next 24
hours. Onshore flow increasing this evening will give rise to sca
winds in the strait tonight. High pressure over the NE pacific will
maintain onshore flow through the remainder of the week so SCA winds
may be routine in the strait each night. The outer coastal waters
may see N NW gales on Friday. Smr

Hydrology The daily hydrology discussion has ended until the
start of the next rainy season; it will only be updated as needed
until then.

Sew watches warnings advisories
Wa... None.

Pz... Small craft advisory until 5 am pdt Thursday for coastal waters
from CAPE flattery to james island 10 to 60 nm-coastal
waters from james island to point grenville 10 to 60 nm-

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
