8/26/2020 The 7 day forecast is taking about 5 seconds to load but it will eventually load. NOAA is still working on it. 8/18/2020 NOAA continues to have trouble. Wind guest will occasionally be left off graphs. I am working with NOAA to resolve the issue. 12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

Area Forecast Discussion National Weather Service Seattle WA 821 AM PST Mon Jan 25 2021
UPDATE /MORNING UPDATE/. Clouds will scatter out slightly later this afternoon. Highs are expected to be in the mid 40s throughout the Western Washington area the next few days. We are still monitoring the conditions for possible low land snow Tuesday night into Thursday. With cold air aloft and at the surface, and dropping snow levels, most of Western Washington has the potential to see some flakes falling Tuesday night. As temperatures begin to rise come Wednesday morning, we do not foresee much accumulation happening for the majority of the lowlands. If you are higher up in the hills or in Northern Whatcom county, you will likely see a nice dusting.

SYNOPSIS. A front will reach the West Coast tonight--the heavier precipitation will go into California. Additional weather systems will arrive late in the week or over the weekend. The snow level will be low through the week for a chance of spotty light snow at times in the lowlands with gradual warming next weekend.
SHORT TERM /TODAY THROUGH WEDNESDAY/. Scattered showers will linger today, especially north of Seattle with a weak upper trough over the area. Some sun breaks are possible as well. Snow levels will be 1000-1500 feet. The air aloft will be pretty cold resulting in steep lapse rates and some instability, especially near the coast where an isolated rumble of thunder is possible. Highs will be a few degrees below normal - lower to mid 40s.
The upper trough will weaken and shift inland tonight with an upper ridge briefly moving over the area on Tuesday. This should dry things out although rain will return again at the coast Tuesday afternoon as the next frontal system nears.
The aforementioned frontal system will move through the area Tuesday night but most of the associated precipitation is heading south. Snow levels will once again be low for a threat of snow most areas. However, precipitation looks light and only minor accumulations (less than an inch), if any, are expected. This is backed up by ensemble solutions which show just a few tenths of an inch of snow for most of the area on average.
Another baggy upper trough will be over the area on Wednesday for some lingering light showers. Snow levels will rise to 500-1000 feet in the afternoon largely ending the minor lowland snow accumulation threat for the day. Schneider
LONG TERM /THURSDAY THROUGH SUNDAY/. A nondescript upper trough will be over the area on Thursday for a few showers will snow levels generally 1000-1500 feet. A weak upper ridge will briefly move over the area on Friday for largely dry day. Snow levels will remain around 1000 feet and a few showers will linger.
A more interesting scenario is setting up for Friday night/early Saturday morning. A wetter frontal system is forecast to overrun the cooler air currently in place. Low level flow will initially be somewhat easterly. This could bring some actual accumulating snow to favored areas like Hood Canal and the Kitsap Peninsula but its still several days out so confidence in the details is pretty low for now.
The lowland snow threat should end later Saturday as low level southerly flow increases Saturday and continues into Sunday. The Friday night frontal system will quickly be followed by another weather system Saturday night for a relatively wet weekend. Schneider
AVIATION. Upper level trough near the coast weakens and moves inland Tuesday. Southwest flow aloft. Areas of MVFR cigs are mainly around Puget Sound this morning, there is some stratus with bases around 010 from Skagit county into the San Juans. Conditions should improve into the afternoon as the air slowly dries. Showers with the upper trough should stay near the south coast. Scattered showers especially near the coast--although there are showers around Western Skagit and Whatcom county this morning and some wet snow will probably mix in at times. 19
KSEA . Ceilings improving into the afternoon and the clouds might scatter out later today. Light south wind for now, light gradients tonight with light and variable wind becoming easterly Tuesday.
MARINE. Weak surface low dissipating over the waters today. Another front will arrive Tuesday night and move inland south of the area. Surface low center remaining over the Oregon coastal waters Wednesday and Wednesday night. Weak offshore flow Thursday into Friday.
Small craft advisories remain in effect for 10 to 15 foot seas over the coastal waters and at the West Entrance to the Strait of Juan De Fuca through tonight. Small craft advisory southeast winds developing over the coastal waters Tuesday morning with gales possible Tuesday afternoon and evening. Small craft advisory winds possible for the Strait and Northern portion of the waters Tuesday as well. winds and seas easing all waters Wednesday.
HYDROLOGY. River flooding is not expected for the next 7 days.
