Area Forecast Discussion National Weather Service Seattle WA 935 AM PST Mon Feb 24 2020
UPDATE. Convergence zone continues to linger across portions of the central Cascades at this hour. Obs across the area show that this activity is light, with liquid accumulations generally 0.1" or less over the past 3 hours across the area. Due to this, the Winter Storm Warning for the central Cascades will be allowed to expire at 10am. Light snow showers will likely continue into the early afternoon hours before the convergence zone dissipates, yielding light snowfall accumulation and little in the way of additional impacts.
Pullin
AVIATION. Northwesterly flow aloft continues across the region today with an increasingly stable air mass in place. Mostly VFR conditions across the region with scattered showers this morning, though local pockets of MVFR may remain through the morning. Additionally, remains of a convergence zone over eastern Snohomish County will result in locally heavier precipitation and reduced flight conditions into the afternoon. Otherwise, expect a broken to overcast lower VFR cloud deck to persist through much of the day.
KSEA . Expect predominantly VFR conditions through the period with broken to overcast high clouds and occasional scattered deck around 3000 ft remaining. Surface winds remain mostly southerly through the evening at 5 to 10 kt.
Cullen
MARINE. Weak high pressure rebuilds across the waters today, with winds gradually easing through the morning. A weak front approaches the coastal waters, but will fall apart as it does. Winds are expected to remain below advisory criteria with this system, but southerly winds increase a bit. After this, weather impacts are not expected over the waters through much of the week with relatively light winds. Seas remain around 15 ft this morning, but will gradually subside below 10 ft by early Tuesday. A larger swell arrives around mid-week, but only builds seas to generally 9 to 11 ft over the coastal waters.

PREV DISCUSSION. /issued 322 AM PST Mon Feb 24 2020/
SYNOPSIS . Lingering lowland rain showers and Cascade snow will continue this morning before conditions dry out this afternoon as high pressure builds in. Another weak front will move across the area Tuesday into Wednesday. After a quick break Thursday into Friday, a more organized front may approach the area late Friday, bringing unsettled weather through much of the weekend.
SHORT TERM /TODAY THROUGH WEDNESDAY/ . Water vapor loop this morning shows the shortwave that was responsible for yesterday's weather has since dug into the northern and central Rockies, with a broad ridge building into the Pacific Northwest in its wake. At the surface, yesterday's frontal system has moved well east of the area, with high pressure from the Pacific building into the local area in its wake.
Recent radar loops show some lingering shower activity over the area early this morning, associated with an unstable post-frontal environment. Mainly seeing some pin-prick showers west of Puget Sound across the Olympic Peninsula and just offshore, with some more significant precip seen east of Puget Sound from northern King County northward, of which includes a Puget Sound Convergence Zone. Hi-res model guidance has struggled with the development of this convergence zone, but with recent observations still showing gale force winds down the Strait of Juan de Fuca, with weaker southerlies across Puget Sound, it seemed realistic to think one would develop.
Into and through the morning hours today, will need to carefully monitor the PSCZ. Given the strong winds down the Strait, would think the zone would shift south before eventually dissipating. However, until this happens it will likely cause some additional impacts across the central Cascades. Since its development, Stevens Pass has picked up a few more inches of snow, with light snow also in close proximity to Snoqualmie Pass. With the convergence zone lingering, have opted to extend the Winter Storm Warning for the central Cascades through 10am/18z this morning. The remaining Winter Storm headlines will be allowed to expire at 4am/12z this morning. The convergence zone will also have to monitored across the lowlands of King and Snohomish Counties. Snow levels will drop to below 1000 feet through the morning hours, tho perhaps not quite as low as originally forecast. Nevertheless, any convective-like areas within the convergence zone may drive snow levels down even further/cool the atmospheric column within. This may provide for a brief window of opportunity for a rain/snow mix, especially across the higher hilltops. At this time, no impacts are expected. And this is all assuming the PSCZ can maintain itself into the morning hours.
Going into the afternoon hours today, ridging overhead, providing for strong height rises, with high pressure at the surface should provide for rapidly improving conditions. This return to dry, benign weather will carry into Tuesday, although will likely see some additional cloud cover move in ahead of the next frontal system. By Tuesday, the upper level ridge will dampen in response to a weak shortwave passing through the flow. This shortwave will be carrying a weak surface front with it, which is expected to bring a few showers to the area Tuesday afternoon and evening. QPF with this system is unimpressive and some locations may not even see much of anything. Showers are likely to linger into Wednesday morning before dissipating, leaving dry, cloudy conditions in place for the remainder of the day.
Kovacik
LONG TERM /THURSDAY THROUGH SUNDAY/ . By Thursday, the upper level ridge tries to reestablish itself, which may be enough to shun most of the precip and deeper layer moisture to the north of the area. There will still exist the chance that a few showers could sneak into the far northern sections of the area.
On Friday, upper level troughing looks to become better established across the Pacific, with an organized frontal system noted in the low levels. The front's arrival to the local area may hold off until Friday evening, but it does look to mark the return to unsettled weather. BUT, this will not be until we get to enjoy a relatively mild late February day, with highs on Friday approaching 60! The frontal system will likely yield periods of wet weather through Sunday morning, with perhaps then a brief break in the action until another front moves into the area early next week.
Kovacik
HYDROLOGY . No river flooding is expected over the next 7 days. Lingering precip this morning will dissipate through the day, with snow levels dropping below 1000 feet. A weak front will bring a few light showers to the area Tuesday into Wednesday, with snow levels recovering. QPF will be light with this system, with some locations not guaranteed to see much of anything. After a break in the weather Thursday into Friday, a more organized system may approach the area for the weekend. Not seeing a deep moisture feed with this system, so while precip may be more widespread, precip totals are not expected to be significant enough to pose a threat for river flooding. Forecast QPF over the next 7 days per WPC guidance suggests 1-2 inches across the higher terrain and less than an inch for the lowlands.
