Synopsis Steady rain will become more showery today, but the
weather will remain wet through Thursday. A cooler and somewhat less
wet period will follow Thursday night and Friday. Rain will resume
on Saturday, possibly becoming heavy at times Sunday and Monday as
an atmospheric river pattern develops. Cool and showery conditions
will return Tuesday.

Short term Satellite imagery shows southwest flow aloft with
short waves moving along a front draped over the southeast part of
western washington. Rain at times will continue this morning, then
turn more showery this afternoon. Showers will continue through
Thursday, then taper somewhat Thursday night and Friday.

Snow will continue falling in the mountains, but not as heavily as
in the past 24 hours. Several inches of new snow accumulation today
and several more this evening seem likely. The snow level will rise
to around 3500 feet today. There is a chance the snow could change
to rain at some point in snoqualmie pass but it will keep snowing
elsewhere. A winter weather advisory is in effect for the cascades
and olympics until 10 pm this evening.

A cooler air mass will move into the region tonight. Highs Wednesday
will be in the mid to upper 40s, but on both Thursday and Friday the
highs will be in the low 40s. Overnight lows beginning tonight will
be in the 30s. On Thursday night and Friday there could be a little
snow on the highest hills in more vigorous showers over northern
sections, where the air mass will be coldest. The zones and grids
mention a snow level of 1000 or 1500 feet in northern areas. Burke

Long term Models are in decent agreement now. On Saturday a
warmer weather system will move into the region, raising snow levels
and bringing rain. Much heavier rain is forecast for Sunday and
Monday, as a warm front moves south to north through the area,
stalls, then moves southeast as a cold front sweeps it away. The
upshot is there could be around 48 hours of heavy rain in the
mountains, with plenty in the lowlands as well. After the cold front
passes Monday night or so, a cool upper trough will settle over the
area on Tuesday. Burke

Hydrology The skokomish river in mason county is above flood
stage due to rainfall over the southern olympics on Tuesday. It's
going to keep raining off and on there through Thursday or so. The
forecast for the skokomish is for it to crest somewhere in the minor
flooding category today, then slowly recede over the next 48 hours.

The rain forecast for Saturday will not produce any more flooding,
except perhaps on the skokomish. However, the rain in the models
Sunday and Monday shows an atmospheric river pattern and it is
likely to cause more widespread flooding. The combination of heavy
rain in the mountains and snow levels rising above 5500 feet usually
causes flooding on many area rivers. Models also show plenty of rain
in the lowlands, so some urban and small stream flooding this
weekend is also possible.

The USGS landslide threshold indices were near or slightly above
the thresholds where landslides become probable. The additional
rainfall this week, and especially this weekend, will increase the
threat of shallow landslides. Burke

Aviation Southerly flow aloft will prevail today as a frontal
system slowly exits the area. An upper level disturbance will move
through the area late this afternoon causing the current moist and
stable air mass to destabilize through tonight.

Cigs continue to be a mixed bag this morning with the majority of
conditions being eitherVFR or MVFR with isolated ifr conditions
possible under showers. This is not expected to change much during
the morning hours but might see some slight improvement in the
afternoon.

Ksea... CIGS currentlyVFR but may dip down into MVFR this morning
and afternoon... With improvement expected this evening. Winds remain
southerly 6-12 knots increasing to 14-17 with gusts to 25 knots this
evening. Smr

Marine In the wake of the passing front... Winds are coming down
slowly. Will likely have to tinker with timing to some degree... With
some extensions... But should generally see headlines starting to
fall by late this morning. 10-12 foot swell for the coastal waters
look to linger into the afternoon. With winds over coastal waters
staying in small craft advisory thresholds at least through the
morning... Will leave headline unaltered with the morning forecast
package.

Additional disturbances will move through the area over the next
few days for small craft advisory strength winds at times.

Stronger systems are expected Friday night and Sunday. Schneider smr

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.
