UPDATE
No changes have been made to this evening's inherited forecast. Overnight lows are to range between the upper 20s to mid 30s. The previous discussion remains below along with an update marine/aviation section.
SYNOPSIS
Dry and cold weather tonight. A weak system Thursday will be the first in a series that are expected to affect the Pacific Northwest into early next week. This includes two atmospheric rivers expected to affect the region - the first Saturday into Sunday, then a second potentially stronger event Monday into Tuesday. These systems will bring breezy conditions with lowland rain and heavy mountain snow Thursday and Friday, transitioning to more widespread heavy rain and potentially windy conditions over the weekend into early next week.
SHORT TERM /TONIGHT THROUGH SATURDAY/
One last night of dry and cool weather tonight. Overnight lows will likely be a bit warmer than we have seen over the last few days due to the increasing cloud cover ahead of the expected weak system on track to move into the area tomorrow. This will also likely help limit the fog overnight, with patchy fog likely to develop again, but not as widespread as we have had over the last few nights - mostly over the Hood Canal area and central Kitsap Peninsula south into Olympia. The weak front will begin to push light precipitation onto the coast after midnight tonight and into the interior through day break. With the colder temperatures there is a chance for wintery mix of precipitation in Eastern Grays Harbor County into Mason, Thurston and Lewis Counties early Thursday morning.
This includes a 10% chance of a short period freezing rain with no accumulation expected. Temperatures should moderate through the morning with light rain spreading through the interior. Snow levels, initially around 1500 will gradually lift to around 2500 feet - allowing for some snow to accumulate at the passes. The first round of snow at the passes will likely equate to 3 to 5 inches by Friday morning.
There will be a brief break in the precipitation early Friday morning before a more vigorous frontal system boosts precipitation, particularly over the mountains. Heaviest period of precipitation looks to be Friday night into Saturday morning, with snow levels still in the neighborhood of 2500 to 3200 feet, additional snow accumulations at the passes Friday morning through Saturday could be as much as 24 to 30 inches. A Winter Storm Watch has been issued from Thursday morning through Sunday morning. In addition this system will bring b, area rivers are likely to see rises through the weekend and likely into next week.
While extended models have had trouble at arriving at a consensus, making it difficult to get a grasp on the full potential impacts to the area, there is at least enough consistency to suggest that hydrologic products may be needed late in the weekend and for the start of next week. Unfortunately, the scope of these products is hard to nail down at this time.
Forecasts will need to be monitored for the remainder of the week in the hopes that a singular solution will eventually emerge.
breezy to windy conditions during the day Friday especially along the coast and the area from Whatcom County and the San Juans southward to Skagit and Island Counties. Precipitation may ease Saturday afternoon. Snow levels are expected to generally rise Saturday evening to above 3500 feet as the first of two atmospheric rivers begin to push warmer and very moist air into western Washington From the Southwest.
LONG TERM /SUNDAY THROUGH WEDNESDAY/
Snow levels early Sunday morning are expected to rise above 4000 feet and precipitation pushes into the area - widespread rainfall with the heaviest accumulations expected over the coast and Olympic mountain Sunday morning and the Cascades Sunday afternoon and evening. By Sunday afternoon snow levels should rang from well above 6000 feet in the south to 5000 feet in the north. Accumulations Saturday evening through early monday morning look to be around 3 inches over the Olympic mountains, and 1.5 to 2.5 inches over the Cascades with the heavier amounts over the King and Snohomish Cascades. This system is likely produce another round of windy conditions Sunday, particularly along the coast and north interior.
Ensembles including ensemble based atmospheric river guidance continue to show a second, stronger atmospheric river pushing another surge of warm and moist air into Western Washington Monday into Tuesday. NBM ensemble guidance showing snow levels easily rising to above 7000 by Tuesday morning with very deep moisture and southwesterly flow resulting in another, more significant round of heavy precipitation. This will follow on the rises on area rivers from the earlier events and will likely elevate the potential for river flooding.
AVIATION
Flow aloft will remain west to southwesterly over Western Washington. A weak frontal system offshore is beginning to work its way towards the region As such, mid to high level clouds around 10,000 ft blanket the region. Patchy fog has brought the more fog-prone locations down to LIFR (OLM, PWT at times). As the front advances into the area Thursday morning, scattered showers will begin around 12Z, then increase to a steady rain after 16Z that lasts through the TAF period. As rain falls across the region, expect ceilings to drop to MVFR to near IFR at times through the day Thursday. Heavier rain showers may temporarily reduce visibility.
Winds are currently light and variable, but will return to mostly southwesterly Thursday and into Thursday night.
KSEA...VFR conditions with a 7000 ft deck with some low clouds and fog southwest of the terminal. As the front moves through expect rain chances to increase between 12 to 16Z Thursday, with ceilings falling to MVFR after 16Z. Winds will remain light becoming southwesterly Thursday.
LH
MARINE
A more active pattern is on our doorstep as a series of frontal systems will move across the region in rapid succession beginning Thursday through next week.
Winds will pick up ahead of the front Thursday morning, which is expected to affect primarily the coastal waters, the East Entrance of the Strait of Juan de Fuca and the Northern Inland Waters.
Therefore, Small Craft Advisories have been issued the aforementioned areas for Thursday. For Friday, a more vigorous frontal system moves through the region with stronger winds. A Gale Watch has been issued for the coastal waters late Thursday night through Saturday morning, as well as the East Entrance and Admiralty Inlet Thursday through Friday afternoon. Additional headlines for winds appear likely this weekend and into early next week.
Seas will begin to rise above 10 ft early Friday morning, and remain around 12 up to 18 ft at times with periods of around 12-14 seconds for the foreseeable future.
LH
HYDROLOGY
The shift to an active pattern tomorrow will set the stage for a series of two atmospheric rivers expected to affect the region - the first Saturday evening into Sunday, and second stronger AR Monday into Tuesday. Snow levels around 4000 feet Saturday night will rise to well above 5500 feet Sunday, and even higher with the second system Monday and Tuesday. Precipitation amounts through the weekend are high enough to drive the Skokomish River to minor flood stage, as well as rises on all area rivers.
The second, stronger system early next week - following on the heals of the first will surely elevate the risk of additional rivers nearing or reaching flood levels. We will continue to monitor the extended forecast as such.
