Area Forecast Discussion National Weather Service Seattle WA 854 PM PST Tue Jan 21 2020

SYNOPSIS. Wet weather for the rest of the week into the weekend as a series of systems moves through the area. Snow levels near passes into Wednesday will rise steadily later Wednesday into Thursday. Periods of heavy rain will lead to rising rivers and the potential for river flooding later this week.

SHORT TERM /TONIGHT THROUGH FRIDAY/. An upper trough brought strong showers, some with rotation near the coast, earlier this afternoon and evening. The strong showers have been fading in the last couple of hours as the air mass becomes more stable but plenty of garden variety showers will continue this evening before tapering after midnight. Snow levels have lowered to between 2500 and 3000 feet this evening with snow, heavy at times in the mountains. Snow should gradually taper later tonight as the upper trough moves inland.

There won't be much of a break in the wet weather as a warm front moves into the area on Wednesday for more rainy weather. This feature will hang up over the area into Wednesday night then gradually shift inland Thursday and Thursday night. This prolonged period of rain, heavy at times in the mountains, combined with much higher snow levels will lead to river flooding concerns. See the hydrology section below for more details.

Steady and heavier rain should turn more showery and lighten up on Friday as an upper trough moves through the area. Snow levels will also drop to more seasonable levels. River flooding concerns will continue however. Schneider

LONG TERM /SATURDAY THROUGH TUESDAY/. Previous discussion . The threat of river flooding continues through Saturday under warm, moist SW flow. A brief break in the action Saturday night or Sunday will bring a respite. Snow levels will lower Sunday night and Monday as a cooler trough pushes inland. This may bring a period of heavy snow in the mountains. The pattern turns warm and wet again early next week with the arrival of a strong warm front. This would renew the flood threat across the region. We may also see some wind impacts, especially along the coast and North Interior. All in all, expect more active weather through this period. 33

AVIATION. An upper trough will shift inland tonight with an upper ridge moving over the on Wednesday. The flow aloft will be westerly. A warm front will lift north into the area on Wednesday. The air mass is moist and unstable. It will become stable later tonight and Wednesday.

There will be a mix of low and mid clouds tonight with lower ceilings generally in showers. Ceilings will lower further with widespread low clouds on Wednesday as a warm front arrives.

KSEA . Low clouds in showers this evening will probably lift a bit after midnight as showers decrease. Ceilings will lower again Wednesday morning as a warm front brings rain. Southerly wind 10-15 knots will ease and become more easterly on Wednesday. Schneider

MARINE. A warm front will lift north across the area on Wednesday, stall over the area Wednesday night, then gradually shift inland Thursday and Thursday night. Most areas will have small craft advisory strength winds through this period. Active weather will continue through the remainder of the week as additional weather systems moves across 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 7,000 feet with 3 to 9 inches of rain in the mountains Wednesday through Saturday. Minor flooding is possible on several rivers as a result. 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.

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.
