Area Forecast Discussion National Weather Service Seattle WA 239 AM PDT Thu Apr 2 2020

SYNOPSIS. Lowland rain and mountain snow will continue off and on for the next several days as a series of weak systems pass through the area. Drier and warmer conditions are possible by the middle of next week.

SHORT TERM /TODAY THROUGH SATURDAY/. A weak upper level impulse will cross the area later today in northwest flow aloft. A mid level cloud deck has been filling in over Western Washington overnight ahead it. The majority of the shower activity that it will generate later this morning and into the afternoon is expected to be over the higher terrain of the Cascades and Olympics. Showers will diminish this evening, albeit briefly, before another upper trough dipping southward over the interior of British Columbia affects the region. Initially, precipitation will likely mostly confined to the North Interior and Cascades early Friday, but there may be enough low level onshore flow Friday afternoon to get a convergence zone going.

Onshore flow relaxes and the upper trough pushes eastward late Friday night for diminishing showers. As they've been previously advertising, the models slide some weak shortwave ridging across the area on Saturday ahead of another upper trough digging southward over the offshore waters. Most of Western Washington should see a generally dry on Saturday with the exception of perhaps a few showers wrapping around the trough into the Southwest Interior Saturday evening. Continuing the recent trend, temperatures through the short term forecast period are expected to remain below normal.

LONG TERM /SUNDAY THROUGH WEDNESDAY/. Following the trends that previous model runs were hinting at, the deterministic runs of both the GFS and Euro now take Saturday's offshore trough well south of the area Sunday into Monday and leave the region generally dry. Despite this, weak troughiness remains over the area and the GFS tries to get a few terrain driven showers going. For this reason, it seem wise to leave a chance or slight chance of showers in the forecast Sunday/Monday. But both operational model runs and ensemble means are pointing to some improvement by Tuesday/Wednesday as upper ridging offshore noses closer to the Pacific Northwest for possible drier conditions and temperatures a little closer to climatological norms. 27

AVIATION. Scattered to broken cloud cover resides across western Washington early this morning. With the exception of HQM, all TAF sites are VFR as of 2am. Model guidance has been suggestive of the development of an MVFR layer of clouds towards daybreak, however, given current trends, confidence is low in the overall coverage. This will be evaluated a bit more before the 12z update, along with the potential for patchy fog development around OLM and PWT. SCT-BKN VFR conditions should be the dominant cig this afternoon and evening. Scattered showers are expected again, mainly this afternoon across the entire area. Winds generally south 5-10kts thru the period, tho initially NE at BLI and overall more westerly at CLM and HQM.

KSEA . VFR cigs may give way to an MVFR stratus deck around daybreak. Conditions should improve back to VFR this afternoon. Scattered showers also expected late morning and into the evening hours. Winds S 5-10kts.

Kovacik

MARINE. A weak frontal boundary remains hung up over the area early this morning, roughly from Vancouver Island into the Eastern Strait and into the Cascades. This is allowing a Northeasterly wind to prevail across the Northern Inland Waters with onshore flow elsewhere. Overall gradients are light this morning with highest wind speeds around 10-15kts. This general trend will continue through the morning and into the afternoon hours, with no marine headlines needed. A weak westerly push is then expected down the Strait of Juan de Fuca later this afternoon and through much of the overnight hours. This is likely to be a marginal small craft wind event, with highest wind speeds around 21-22kts. These marginal winds may bleed into the adjacent Northern Inland Waters for a period of time overnight into Friday morning, so have expanded the SCA to account for this. Gradients appear to remained elevated enough for small craft advisory winds to continue across the central and eastern Strait through Friday.

An active pattern is expected to continue through the weekend with perhaps a dry period and tranquil period setting up for early next week. For now, see no notable marine hazards (wind nor seas) during this time.

Kovacik

HYDROLOGY. An unsettled pattern will continue into the weekend, but precipitation amounts are not expected to lead to flooding concerns.

SEW WATCHES/WARNINGS/ADVISORIES. WA . None. PZ . Small Craft Advisory from 5 PM this afternoon to 8 PM PDT Friday for Central U.S. Waters Strait Of Juan De Fuca-East Entrance U.S. Waters Strait Of Juan De Fuca.

Small Craft Advisory from 8 PM this evening to 8 AM PDT Friday for Northern Inland Waters Including The San Juan Islands.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
