Area Forecast Discussion National Weather Service Seattle WA 845 AM PST Mon Dec 9 2019

SYNOPSIS. Low clouds cover much of the lowlands this morning but should break up in the afternoon. A weak front will move through Western Washington Tuesday afternoon and evening. Stronger weather systems will give Western Washington wet and breezy weather Wednesday night through Friday.

SHORT TERM /TODAY THROUGH WEDNESDAY/. Low clouds and some fog patches cover the lowlands this morning--and then a little sunshine is likely for the afternoon. A transitory upper ridge axis just offshore will shift through the region tonight and Tuesday as it is dented by a weakening front. The front will spread some rain to the coast by the middle of the day and into the I-5 corridor by late afternoon. Ridging pokes back up over Western Washington behind the system Tuesday night and Wednesday morning ahead of the next stronger frontal system that will arrive late in the day Wed.

LONG TERM /THURSDAY THROUGH SUNDAY/. A more active pattern is likely for the second half of the week with wet breezy weather Wednesday night through Friday. An upper trough in the northeast Pacific Wed-Fri will weaken, progress east, and a shortwave on Saturday will mainly affect northern California--leaving Western Washington on the cool showery side of the westerlies for a day. As another trough develops in the north Pacific early next week, downstream ridging occurs over the Pacific Northwest starting on Sunday.

AVIATION. An upper level ridge centered offshore will move inland tonight. Light flow in the lower levels will persist through Tuesday morning. The airmass is moist and stable, with a drying trend expected this afternoon.

Mixed bag of conditions this morning, with ceilings below 1000 feet and visibility 1-3sm in fog. Isolated visibilities 1/2sm or less. Cloud tops 1000-1500 feet. Mid level deck dissipating with ridge moving overhead this morning which will allow the sun to work on the shallow fog layer. Low clouds should scatter out near midday. High level clouds will increase tonight ahead of the next system on Tuesday, but not in time to prevent some areas of fog from reforming around midnight tonight.

KSEA . Current ceilings below 500 feet with visibility 1-3sm in fog and low clouds. Improving trend from 17z-21z with clouds scattering out by the early afternoon hours. Fog could reform after midnight, dropping visibilities down again. Light northeasterly winds through tonight 2-6 knots. Felton/Borth

MARINE. Weak high pressure will remain over the area today. A weakening front will then move through the area on Tuesday, bringing small craft advisory strength easterlies to the western Strait of Juan de Fuca and small craft strength southeasterlies to the Coastal Waters.

A stronger frontal system will then move through the area Wednesday and Thursday. Gales are possible for the Coastal Waters with this system Wednesday night. In addition, west swell will build to around 15 feet Wednesday night and Thursday.

HYDROLOGY. River flooding is unlikely for the next 7 days.

SEW WATCHES/WARNINGS/ADVISORIES. WA . None. PZ .

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.
