930 am pdt Sun apr 30 2017

Synopsis A convergence zone will keep showers over the seattle
area today, with scattered showers elsewhere. A weak weather system
will probably bring showers Monday morning. Upper level ridging will
bring mostly dry weather Tuesday through Thursday although Tuesday
night and Wednesday morning may see a little rain. An upper level
trough will bring rain Thursday night through the weekend.

Short term Radar and a glance out the window shows a nice
convergence zone along the king-snohomish county line this morning.

There are scattered showers on the coast and dry, even sunny,
conditions elsewhere. Models show the convergence zone persisting
into this evening even as other areas dry up. Have updated the grids
and forecasts for higher pops in the seattle area today and this
evening. Highs today will be in the 50s.

What had been a weak system heading into oregon on Monday in the
models is now heading more directly into washington. Light rain
seems likely Monday morning, with some drying in the afternoon. Have
also included this idea in the forecast update. Highs Monday will
also be in the 50s.

An upper ridge will build over the area Tuesday, with heights in the
low 570s. Normally this would be a dry pattern but models move a
weather system into the area, right through the upper ridge. This
seems overdone but the forecast does have chance pops over the whole
area by Tuesday evening. High temperatures will be in the mid 50s to
mid 60s. Burke.Aviation... A flat, transient upper ridge axis will
reach 130w
this afternoon and pass eastward across western washington
tonight. It will be closely followed by a weak upper disturbance
on Monday morning, accompanied by deeper moisture and a few hours
of rain. Today's air mass will be moist and unstable below 10,000
feet msl but dry and stable above. The air mass on Monday will
feature deeper moisture and a more stable air mass. With the moist
air mass, MVFR CIGS of 015-030 will be common, with lifting both
this afternoon and Monday afternoon into the 030-045 range.

Ksea... Puget sound convergence zone will be the main weather
challenge today. As of 915 am, it is evident as a band of showers
and lower CIGS 10-20 miles north of the terminal. It will likely
drift south enough this afternoon and evening to bring showers to
the terminal. A northerly wind shift cannot be ruled out late
this afternoon, but winds are more likely to maintain a southerly
component at sea. Nearby bfi is a bit more likely to get a light
north wind for 1-3 hours around 00z (5 pm). Haner

Marine Moderate and briefly strong westerly onshore flow will
peak late this afternoon, then ease tonight. Currently forecasting
a brief round of low-end westerly gales for the eastern and
central strait late this afternoon and early this evening.

Meanwhile, a puget sound convergence zone will hang out near
bremerton and seattle through this evening. Winds will ease
quickly late this evening. Haner

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.
