Area Forecast Discussion National Weather Service Seattle WA 842 PM PST Mon Jan 20 2020

SYNOPSIS. A weak front will dissipate over the western portion of the area tonight. Additional systems will move through the region Tuesday through the rest of the week with lowland rain and fluctuating snow levels in the mountains.

SHORT TERM /TONIGHT THROUGH THURSDAY/. A frontal system will move through the area on Tuesday with rain changing to showers. This system will bring snow to the mountains with snow levels 2500-3500 feet. It looks like advisory amounts for the passes and heavy snow for the volcanoes. There will also be locally windy conditions, mainly coast and north interior. An isolated thunderstorm is possible near the coast where it will be a little unstable.

The wet pattern will continue Wednesday and Thursday as an atmospheric river affects the area. A warm front will move over the area on Wednesday, stall Wednesday night, then slowly sag inland as a cold front on Thursday. This combined with high snow levels will bring a threat of river flooding. Please see the hydrology section below for more details. Schneider

LONG TERM /FRIDAY THROUGH MONDAY/. Previous discussion . Periods of heavy rain will continue into Friday, and possibly Saturday, as more wet Pac systems roll through the region. Rivers will continue to run high with flooding still a threat. A break in the pattern Saturday night and Sunday will bring a brief respite. A cooler upper trough will bring more rain and mountain snow early next week. 33

AVIATION. A frontal system will move into the area late tonight then push inland on Tuesday. Southerly flow aloft tonight will become westerly on Tuesday as an upper trough moves over the area. The air mass is moist and stable. It will become slightly unstable near the coast on Tuesday.

Mostly mid and high clouds across the area this evening ahead of a front. There will be some patchy low clouds and fog in a few spots however. Ceilings will lower late tonight as the front arrives with low clouds across the area on Tuesday.

KSEA . Mid and high clouds most of tonight. Low clouds and rain will develop Tuesday morning as a front arrives. Easterly wind 4-8 knots will become southerly 10-15 knots on Tuesday. Schneider

MARINE. A frontal system will bring gales to the Coastal Waters later tonight and Tuesday and perhaps the Central Strait and East Entrance Strait of Juan de Fuca as well. Small craft advisory strength winds are expected all other waters with the front.

The pattern will remain active for the rest of the week as a series of weather systems move through the area. Schneider

HYDROLOGY. A period of warming, rising snow levels, and heavy rain in the mountains will force sharp rises on the rivers flowing off the Olympics and Cascades in western Washington. Snow levels will rise to around 5,000 to 6,000 feet with 3 to 6 inches of rain in the mountains Wednesday through early Friday. Minor flooding is possible on several rivers as a result. Rivers may be flowing high through the weekend before receding.

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.
