SYNOPSIS
A weak system today will be the first in a series that are expected to affect the Pacific Northwest into early next week. A stronger system will impact the region Friday into Saturday, with more widespread rain along with significant mountain snow and breezy conditions. Multiple atmospheric rivers look to impact our region this weekend and into next week with possible heavy rain and breezy conditions.
SHORT TERM /TODAY THROUGH SATURDAY/
Latest satellite imagery shows some mid to high level clouds streaming in ahead of an approaching front. Widespread fog will likely be limited this morning throughout W WA, but could see localized patchy fog over Hood Canal, into Kitsap Peninsula south through Olympia. The aforementioned approaching front will push in light precipitation starting at the coast and working inward early this morning into the afternoon. With low temperatures this morning still hovering around 32 to 35 degrees, could see a slight mix of wintry precipitation in Eastern Grays Harbor County into Mason, Thurston, Lewis, and southern Kitsap county. There is a very small chance (5 to 10%) of a short period of freezing rain in these locations, although it is very unlikely. Precipitation is looking rather light with this front, so little to no accumulation is expected on the off chance wintry precipitation does develop in these locations.
While the front passes through our region this afternoon with light rain, temperatures will moderate to the lower 40s into the mid 40s through the interior. Snow levels around 1500 to 2000 feet will gradually rise to around 2500 later this evening, allowing snow a chance to accumulate at Snoqualmie and Stevens Pass, around 3 to 5 inches by late tonight.
A more vigorous frontal system will enter Western Washington early on Friday, marking the start of a more active weather pattern.
This frontal system will bring more precipitation to the lowlands, and significant mountain snow. Snow levels look to be generally around 2000 to 2500 feet, with snow accumulations potentially up to 2 to 3 feet in the mountains (including the passes). Therefore, have upgraded the Winter Storm Watch to a Winter Storm Warning starting early Friday morning into early Sunday. Traveling through the passes will be difficult during this time. The Winter Storm Watch for the Olympics has been downgraded to an Advisory. Along with the rain, and higher elevation snow, gusty winds could be possible along the coast and areas like Whidbey Island northward.
Another frontal system will impact the area on Saturday evening, bringing copious amounts of moisture along with it, breezy conditions, and mountain snow. Although during this time, snow levels look to gradually rise to 3500 to 4000 feet - limiting snow to higher elevations. With moisture being plentiful and snow levels a touch higher, heavier rain in the mountains is likely, leading to increasing hydrologic concerns regarding rising rivers, and snowmelt runoff.
LONG TERM /SUNDAY THROUGH WEDNESDAY/
Another system will bring widespread rainfall into Sunday, with snow levels rising above 4500 feet. The rainfall will likely be he heaviest in the Olympic mountains and basins, and the Cascades by Sunday afternoon. Snow levels will continue to rise above 6000 feet in the afternoon, with heavy rain impacting the mountains. Again, with snow levels rising during this time, hydrologic impacts will continue to be monitored especially in the long term, focusing in on the continuous rainfall in the mountains, which will likely lead to rising rivers and snowmelt runoff. A hydrologic outlook has been issued to discuss the hydrologic concerns for this weekend and into early next week.
Model guidance, including ensemble based members, depict another atmospheric river pushing a swath of warm Pacific moisture in W WA, entering Monday into Wednesday. NBM percentiles show snow levels rising into the 7000 to 7500 foot range, along with temperatures exceeding 50 degrees. This will likely lead to another round of heavy precipitation, whereas hydrologic impacts will likely elevate even more river flooding.

AVIATION
Westerly flow aloft will back to southwesterly later today as an upper trough and associated frontal system move into the region. Ceilings will lower to MVFR along the coast later this morning as light rainfall spreads onshore. These conditions will spread to interior areas around Puget Sound 22Z-02z.
KSEA...Ceilings expected to remain at or above 4000 feet this morning before gradually lowering to MVFR by around 00Z as light rainfall reaches the area. Ceilings between 1500 and 2500 feet in light rain expected from this evening into early Friday A.M.
Surface winds light southeasterly becoming southerly this evening and increasing to 7 to 11 knots. 27
MARINE
A weak warm front draped across the coastal waters this morning will be followed by a dissipating cold front that will move onshore late this afternoon. This will produce Small Craft Advisory winds across the coastal waters as well as the west entrance to the strait. A stronger system will arrive on Friday with a triple point expected to make landfall near Cape Flattery early Friday morning.
This will likely generate gales over the coastal waters near frontal passage as well as pre-frontal SE gales near the east entrance to the strait. A fairly strong westerly surge will follow the surface trough. Another strong front will reach the area early Saturday for additional headlines. Heading into the coming week, the pattern shows no signs of abating as a broad trough of low pressure anchored over the Gulf of Alaska directs a series of vigorous systems across the waters.
Seas will rise above 10 ft early Friday morning and remain in hazardous double digits until further notice. 27
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. An hydrologic outlook has been issued to further discuss the potential for river flooding.
