SYNOPSIS. Mostly dry and warmer conditions across the region through Thursday as quasi-zonal flow gives way to high pressure aloft. A pattern change late Thursday will see a return of wet weather to Western Washington Friday through the first half of next week.
SHORT TERM /TONIGHT THROUGH THURSDAY/. Ongoing showers associated with the remnants of this mornings convergence zone are trending down this afternoon, with only isolated showers remaining across Admiralty Inlet and portions of Snohomish County at this hour. Visible satellite imagery shows some breaks in the clouds beneath the thin, broken upper level cloud layer, allowing for some moments of sun. Less low level cloud cover is being observed at this hour from Tacoma southward and westward, where low level clouds have mostly mixed out this afternoon and influence from convergence are non-existent. Dry conditions will prevail tonight under mostly cloudy skies.
A large upper level low embedded in the southern flank of the polar jet will eject across Southern California tonight and into the Great Basin by Wednesday night/early Thursday. This, coupled with an approaching upper level low ejecting out of the Gulf of Alaska will amplify the NW to SE oriented ridge, with the ridge axis likely oriented east of Western Washington. While we are expecting warming temperatures, this will be a limiting factor in how warm we will get on Wednesday and Thursday. While 60 degrees F is not out of the question on Thursday, timing of the onset of clouds and rain will be a factor. An onset of clouds and rain earlier on Thursday will preclude warming, while clouds and rain moving into the region later in the afternoon will likely allow readings to hit the 60 degree mark for the second time this week in some areas and for the first time this year in others. With a deepening upper level low tapping into a large fetch of Pacific moisture approaching the coast Thursday night, a shift from quiet and mild weather is expected, as increasing winds along the outer coast and rain are expected to impact the region Friday through the weekend.
LONG TERM /FRIDAY THROUGH TUESDAY/. There remains some variance in ensemble guidance regarding exactly where the bulk of the upper level energy will impact the coast. There remains a signal in the upper level ensemble guidance in a secondary upper level shortwave trough ejecting southeastward out of the parent low and into the southern OR/NorCal coast late Friday/Saturday. That said, confidence is increasing in a weak AR event setting up from southwest to northeast along the northwest coast Friday and Saturday. That said, there are several factors that will preclude widespread flooding with this particular AR setup:
1) Snow levels: These will only rise to ~4000-5000 feet at the most across the region, cutting down the rainfall efficiency.
2) Progressive storm pattern: The AR will only remain pointed at the Olympic Peninsula for roughly 24 to 36 hours before the upper low pushes the moisture eastward.
These factors will limit rainfall amounts and snowmelt runoff through this event. There is reasonable confidence in at least 1 to 2 inches of rainfall from Thursday night through Saturday, with slightly higher amounts in the Olympics. As a result, flooding potential will likely be limited to the Skokomish River basin, with lower potential for urban flooding due to less intense rainfall rates. Aside from rain, breezy southerly winds are expected along the coast through Friday evening.
Active weather will persist through the remainder of the period as another system will eject out of the Gulf of Alaska on Sunday, bringing another round of wet and active weather to the region through the end of the period. It is important to note that there is a wide range of solutions regarding the strength and location of this system which will affect the finer details of the resultant weather. The bottom line is, expect unsettled weather to persist from this weekend through at least the first half of next week.

AVIATION. Westerly flow aloft. Light low-level flow will become southerly on Wed. The air mass is stable and fairly moist. The mountains are partly to mostly obscured especially in the central Cascades. Areas of stratus finally broke up this afternoon but will set back up to some degree overnight. Mid and high clouds will cross the area at times as well.
KSEA . Nice to see the PSCZ give up and the filtered sunshine this afternoon. Some clouds will set back up overnight but we should be done with the low cigs and drizzle.

MARINE. Weak high pressure builds over the area but a warm front will brush the area later on Wednesday. A stronger front will arrive Thursday or Friday with southerly gales possible across the coastal waters and portions of the inland waters. Coastal swell will ease a bit but then build right back up again for the end of the week.

HYDROLOGY. An atmospheric river is expected to affect Western Washington late Thursday night through Saturday. At this time, several limiting factors will keep the flood threat isolated to the Skokomish River basin during this timeframe.
1) Snow levels will only rise to 4000 to 5000 feet across the Olympic Peninsula, limiting rainfall efficiency.
2) Event duration. The AR will remain pointed at the Olympic Peninsula for ~24-36 hours at the most. Rainfall amounts will generally range from 1 to 2 inches across most locations, with higher amounts to 3 inches in the higher elevations of the Olympics.
These factors coupled with a mostly dry week will limit the flooding potential across the region. An additional system will bring additional rainfall to Western Washington Sunday through early next week.
