UPDATED WARNING LIST AT BOTTOM

SYNOPSIS
Cool onshore flow will continue over the next several days. Embedded disturbances in the westerly flow aloft will maintain showers, along with snow at times above 2500 feet in the Cascades.
Back to milder weather later this week, with a dry day or two. Then, return to unsettled weather for next weekend.

SHORT TERM
(Today through Tuesday)...Feels more like March rather than late April across the region, with plenty of clouds and showers. Zonal (westerly) flow off the Pac into the Pac NW persists through Tuesday.

Next system will push across the region later today into this evening. As such, will see showers increase in coverage and intensity by afternoon. Still cool with temperatures staying in the 50s for the most part. Interestingly, main effect from this system today will be to usher in bit cooler air aloft. This will allow for instability to increase a tad, just enough to introduce a meager possibility of thunder this afternoon into this evening. Does seem that that potential will be over western Washington, and just clipping far northwest Oregon. Models over past few days have been back and forth on this potential, as to whether or not would be there for today. But, based on current satellite and model trends, can not ignore it. So, will maintain a slight chance (10-20%) for a thundershower later today into this evening.

As cooler air aloft spreads inland tonight, will see snow levels lower a bit more, settling around 2500 ft late tonight into Monday, but down to 2000 ft over the Washington Cascades. While snow accumulations are below standard criteria, it is late season and with most cars no longe have snow tires or studded tires, will maintain the current winter weather advisory. Accumulations generally in the 2 to 8 inches range tonight, with the higher accumulations being in areas above 4000 ft.

Not much change for Monday, as will see plenty of showers across the region. Should see some breaks in the cloud cover for the afternoon.
Air mass still remains cool aloft, enough to maintain that small chance of thundershowers, especially along the coast over the Coast Range/Willapa Hills into the interior. Snow continues at times in the Cascades. But, accumulations will vary thanks to showery nature of the precipitation. Likely another 2 to 8 inches in the Cascades.

Yet another system arrives on Tue. This will be a bit stronger, enough so could see couple of hours of steady light rain for a time Tue morning as the low pushes into western Washington. Otherwise, another showery day, with uptick of south to southwest winds. Ahhh, April showers bring the May flowers. /Rockey

LONG TERM
(Wednesday through Friday)...Overall confidence is low to moderate as the pattern stays rather progressive into late next week. Deterministic and ensemble guidance continue to struggle to resolve the longitudinal placement of ridge/trough features going forward. Wednesday guidance has continued to trend a little drier nudging a larger scale upper-level low further north while a transient ridge glides over the region.
Out of all the ensemble solutions available, this scenario is present in roughly 60% of them in addition to the latest deterministic ECMWF and GFS. Thursday and beyond, model uncertainty becomes truly significant with nearly a 50/50 split between maintaining a ridge feature overhead or bringing a potent trough into the region by Thursday and becoming most defined Friday.

AVIATION
Expect a mixture of low-end VFR and high-end MVFR conditions through the TAF period as a series of weak fronts push across the airspace. This will result in scattered showers which could also result in lowered visibilities and ceilings at times. Generally a slight chance (20% probability) for thunderstorms across the airspace starting around 20Z Sunday and persist through at least 12Z Monday. Generally westerly winds through the TAF period with coastal locations having gusts up to 20 kt, with southerly winds for inland locations having gusts up to 15 kt.
Mountains being obscured through the TAF period will be likely.

Notes: The ASOS at KTTD is only available via the dial in option.
The AWOS at KMMV is still out of commission, but a tentative work around has been implemented. There is no estimated time of full repair and restoration for either of these locations.

PDX AND APPROACHES...Mixture of low-end VFR and high-end MVFR conditions with scattered showers. Slight chance (20% probability) for thunderstorms starting around 20Z Sunday and persist through at least 12Z Monday. Southerly winds with gusts up to 15 kt. /42

MARINE
Active weather is expected to continue this weekend an into the start of the week. A surface front moving through the waters this evening will bring another round of elevated winds along with steep and choppy seas. Therefore have issued a series of small craft advisories through at least Monday afternoon.
Generally westerly winds through this time with gusts up to 25 kt and seas of 6 to 9 ft at 10 to 13 seconds through Monday.

A series of weak fronts will move through the waters this week bringing elevated winds and seas at times. Some models are suggesting that small craft conditions could develop with each frontal passage, will continue to monitor the situation as it develops. /42
