Area Forecast Discussion National Weather Service Seattle WA 422 AM PST Wed Feb 24 2021

SYNOPSIS. A drier day is on tap for today as upper level ridging nudges into Western Washington. Drier conditions will remain short-lived, however, as the next system approaches the region tonight and moves through Western Washington Thursday and Friday, bringing additional lowland rain, gusty winds, and periods of heavy mountain snow to the area. Showers will taper early Saturday, for another break in the weather over the weekend.

SHORT TERM /TODAY THROUGH FRIDAY/. The convergence zone showers that produced the mix of rain, snow, graupel, and small hail last night have primarily diminished across the region as of early this morning. With clearing across the region overnight and with plenty of residual low level moisture, areas of patchy fog have begun to develop across the central and southern portions of the Sound, with additional fog development possible for areas across the Southern Interior through the early morning hours. Overall, expect a brief break in the weather for the region during the day today, with patchy fog making way for partly sunny skies this morning. High clouds will start to move in overhead by early afternoon as the next system approaches the area from the northwest. Afternoon highs will be in the low to mid 40s.

The next impactful system will approach the region tonight and move through the area Thursday and Friday, bringing another round of gusty winds, lowland rain, heavy mountain snow, and high surf to the region. Hazards are outlined in detail below:

Lowland Rain: Most areas along the Sound look to get 0.10 to 0.50 inches with this next system. Highest rainfall totals look to remain along the Pacific Coast, where amounts of 0.5 to 1.0 inch are likely, with localized heavier amounts of 1.5 inches possible.

Mountain Snow: Periods of heavy mountain snow are likely from Thursday morning through Friday night. Hi- res guidance hints at the possibility of convergence zones setting up in the wake of the frontal system, which could bring localized heavier bands of snow to the portions of the Cascades. Current forecast calls for snow amounts across anywhere from 18-30 inches for the Cascade passes and for 8 to 20 inches for portions of the Olympics. Pass travel will become difficult at times, so those with cross- Cascade travel plans should continue to monitor the forecast and make sure to check latest WSDOT road conditions before heading out.

Winds: Another hazard from this system will be from high wind gusts, as model guidance tonight is showing 2 distinct periods of strong winds. As the system approaches western Washington, gradients will tighten, causing strong, gusty southwesterly winds along the outer coast and across the San Juans and Admiralty Inlet into the Skagit/Whatcom County coast. Winds will remain elevated through Thursday morning, before shifting to the west behind the front and increasing once again Thursday evening/night. The strongest winds with the second wave are most likely along the outer coast, though gusty winds will again be possible across the San Juans and Admiralty Inlet through Friday.

High Surf: Seas will build to 20-23 feet along the coast by late Thursday night and will remain elevated through Friday afternoon. Large waves may cause beach erosion and carry debris up onto area beaches.

LONG TERM /SATURDAY THROUGH TUESDAY/. Showers from the aforementioned system will linger into early Saturday, before tapering. Conditions then look to dry as upper level ridging traverses the region. There remains uncertainty in deterministic and ensemble guidance regarding the extent of the drier weather, however, as guidance does indicate some weaker systems riding the ride and making their way into the area by early next week. Have kept a chance of POPs in the forecast, however will have to see how the forecast evolves over the next several days. 14

AVIATION. Precipitation has diminished across Western Washington at this hour. Fog has developed across portions of the region, including near KSEA/KBFI and KOLM at this hour. Expect IFR to LIFR vsbys and CIGs at these terminals through at least mid-morning before conditions improve. Elsewhere, VFR conditions will prevail through late in the period, with the aforementioned terminals seeing vsbys improve and CIGs lift and scatter to VFR by late morning or early afternoon. Prevailing winds will generally be light (AOB 5kts) and variable through late this afternoon/this evening before becoming southerly/southeasterly 5-10kts with the approach of another system. Increasing clouds and lowering CIGs expected this evening with -RA spreading from west to east between 08-12Z.

KSEA . Fog has developed at and in the vicinity of the terminal at this hour with visibilities fluctuating between 1/2 mi and 1/4 mi at times. Expect fog to persist at the terminal through most of the morning, with vsbys slow to improve. At this time, IFR visibilities could persist through 16-17Z before improving between 18-20Z. CIGs will lift and scatter this afternoon, with VFR conditions resuming once again this afternoon. Prevailing winds light out of the southeast through much of the day, increasing and becoming more southerly this evening and tonight with the approach of the next system. Increasing clouds and lowering CIGs through the evening and overnight hours with -RA spreading from west to east between 08-12Z. Current timing would bring -RA into the vicinity of the terminal around 12Z, with reductions to MVFR CIGs and vsbys possible.

Pullin

MARINE. Elevated seas offshore will continue to decrease below 10 feet through tonight. A lengthy period of hazardous winds and seas are expected to commence later today. Winds will increase with the approach of the next system this afternoon and evening, with advisory level winds expected by this evening across offshore and most inland water areas. Gales are likely offshore and across the Northern Inland and Admiralty Inlet waters late tonight through Thursday as southerly winds increase as the front approaches. Winds will become westerly Thursday afternoon and increase Thursday evening, with Gale conditions expected offshore and across the Strait of Juan de Fuca into Friday morning. Winds look to remain elevated into the weekend, gradually decreasing through the day Saturday.

Offshore seas will sharply rise Thursday as a 25 to 30 foot swell train approaches the outer coast. Seas in the nearshore waters will range from 20 to 25 feet at times Thursday night as swells peak. Seas will gradually decrease through the weekend, likely not falling below 10 feet until late Saturday night.

Pullin

HYDROLOGY. The lowest reaches of the Chehalis River have continued to rise overnight, so have kept the flood watch for Grays Harbor County going. The crest at Porter may be very close to flood stage late this morning, but is expected to gradually recede throughout the remainder of the day. Additional precipitation arrives tonight into Thursday, but with modest amounts and relatively low snow levels, no additional river flooding is expected at this time. 14

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