Area Forecast Discussion National Weather Service Seattle WA 522 PM PST Sun Dec 8 2019

UPDATE /THIS EVENING/. Radar shows some showers have bubbled up in the last few hours. The forecast was updated to add spotty light showers to the interior from about Seattle south. The expectation is that these showers will diminish this evening with dry weather after that as an upper ridge builds over the area. The remainder of the previous AFD is still valid and included below.

PREV DISCUSSION. /issued 338 PM PST Sun Dec 8 2019/

SYNOPSIS . Western Washington will remain dry into Tuesday as an upper level ridge builds across the Pacific Northwest. The next system will move through on Tuesday afternoon and evening, with an wet and unsettled pattern expected for the second half of the week.

SHORT TERM /TONIGHT THROUGH WEDNESDAY/ . Current satellite imagery indicates plenty of cloud cover across the region this afternoon. With ample low level moisture still across the region, expect the remainder of the afternoon and evening to be mostly cloudy. Some clearing has occurred over the mountains however, mainly across portions of the northern Cascades. Showers have tapered this afternoon and the remainder of the area should remain dry. Overnight lows will be in the upper 30s to low 40s.

The upper level ridge will keep the region dry Monday into Tuesday. The next system will approach the coast Tuesday morning and make its way inland Tuesday afternoon and evening. Both deterministic models and ensemble means continue to indicate the front weakening as it progresses inland, with QPF values remaining rather low. A weak shortwave ridge will build in behind the system, before a stronger front arrives on Wednesday.

Deterministic models remain in disagreement over the timing of the system on Wednesday, with the ECMWF bringing this system inland to the Sound by late afternoon. The GFS remains a bit slower in its solution, with the frontal system only making it inland by the evening hours.

Afternoon highs over the next few days will be in the upper 40s to low 50s, while overnight lows will be in the mid 30s to low 40s.

LONG TERM /THURSDAY THROUGH SUNDAY/ . A period of wet and unsettled weather is in store for the second half of the week as a series of systems moves inland across the region. However, deterministic models and ensembles do hint at a few breaks in the precipitation in the long term, most noticeably on Saturday as a weak upper level ridge temporarily builds back into the area. Temperatures in the extended timeframe will mostly be in the mid 40s to low 50s, with overnight lows in the upper 30s to lower 40s. 14

AVIATION . North northwesterly flow aloft into Monday with upper level ridge offshore. Light flow in the lower levels with flat surface gradients. The air is moist and cloudy across most of Western Washington but some of the higher mountains are sticking up out of the clouds and there have been breaks in the clouds this afternoon. Low clouds will spread out and cigs will lower again tonight with low clouds and patchy fog through Monday morning.

KSEA . Low clouds will set up tonight and persist through midday Monday. Light and variable winds.

MARINE . Weak low pressure will give way to weak high pressure on Monday. A front will break up as it reaches the area Tuesday. A stronger frontal system will affect the area Wednesday and Thursday with a round of breezy weather.

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

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

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.
