Area Forecast Discussion National Weather Service Seattle WA 848 PM PST Wed Jan 22 2020

SYNOPSIS. Active weather will continue over the next week as a series of weather systems move across the area. Rain tonight and Thursday will be enough for a few rivers flowing off the Cascades and Olympics to reach flood stage. Periods of rain will then continue for the remainder of the week and much of the weekend, preventing rivers from experiencing much recovery.

SHORT TERM /TONIGHT THROUGH SATURDAY/. A warm front will stall over the area tonight with rain at times. Rain has tapered a bit over the lowlands this evening but it should pick up again later tonight. There has also been a fairly pronounced rain shadow northeast of the Olympics in west to southwest flow aloft. Snow levels should rise to 6000-7000 feet tonight but easterly flow will keep snow down to pass levels until late this evening. The cold air in the passes should mix later tonight with snow turning to rain. It will also be breezy to locally windy coast and north interior tonight but nothing too impactful.

The atmospheric river over the area will slowly shift inland as a cold front Thursday and Thursday night. The prolonged period of rain and high snow levels will result in river flooding concerns. Please the the hydrology section below for more details.

Some showers will linger over the area on Friday in the wake of the cold front with snow levels lowering to 4000-4500 feet. Another in a series of weather systems will bring more rain later Friday night and Saturday. Schneider

LONG TERM /SUNDAY THROUGH WEDNESDAY/. Previous discussion . Progressive pattern across the Pacific essentially paves the way for a parade of storms to pass across western Washington thru the extended. The first in this series of storm systems will be on Sunday. Given current model runs, this system looks rather interesting (tho it is still far out). A negative tilt shortwave trough approaches the area from the south, with a rather robust sfc low associated with it. Will need to monitor this system for another round of rain and perhaps strong winds. After the passage of this system another shortwave is on tap for Monday, with yet another round of rain. There may be a brief break between systems Tuesday but wet conditions look to return quickly on Wednesday.

Kovacik

AVIATION. The flow aloft will be west tonight with a warm front stalling over the area. The front will start to shift inland as a cold front on Thursday with the flow aloft becoming southwest. The air mass is moist and stable. Low clouds will be widespread with occasional reduced visibilities in rain.

KSEA . Low clouds tonight and Thursday. Visibilities should be reduced at times in rain later tonight and Thursday. Southerly wind 5-10 knots. Schneider

MARINE. A warm front will stall over the area tonight then move inland as a cold front Thursday and Thursday night. Gales are likely for the Coastal Waters late tonight and Thursday morning with small craft advisory strength winds all other waters. Winds will ease a bit later Thursday. The pattern will remain active into early next week with additional weather systems crossing the area every day or two.

In addition, highs astronomical tides and somewhat low atmospheric pressure could lead to a few spots of minor tidal overflow the next few mornings. 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 and increase the risk for landslides across the area. Snow levels will rise to around 5,000 to 7,000 feet with 4 to 6 inches of rain in the mountains today through Saturday. Minor flooding is possible on several rivers as a result. The Skokomish River, which may reach moderate flood stage tonight or Thursday, will likely remain in flood into the weekend. The remainder of rivers may be flowing high through the rest of the weekend. Another period of warm and wet weather may renew the river flooding threat early next week.
