Area Forecast Discussion National Weather Service Seattle WA 856 PM PST Sat Jan 23 2021

SYNOPSIS. Clouds will increase tonight and a front will arrive Sunday. Another weather system will reach the West Coast Tuesday night--with the heavier precipitation moving into California. The snow level will be low through the week ahead for a chance of spotty light snow at times in the lowlands.

UPDATE. Added mention of rain to the forecast this evening from the South Sound southwest through Grays Harbor given the current radar trends. Will see leading edge of the precipitation continue to advance through the waters across the Olympic Peninsula this evening, before reaching the I-5 corridor early Sunday morning. Expect mostly rain at the lowest elevations with the snow level around 500-1000 ft, though cool temperature profiles may support some snow mixing in at times. However, a southerly component to winds and temperatures holding just above freezing should maintain mostly rain. One exception may be in northern Whatcom County as light outflow winds and cooler air may lead to minor accumulating snow north of around Ferndale. Cullen

SHORT TERM /TONIGHT THROUGH TUESDAY/. Clouds will increase tonight and areas of precip should start by daybreak. The hills might pick up a little wet snow tomorrow morning, but accumulations should be mainly in the grass rather than the pavement. If dew points were lower starting out, and precipitation was going to be heavier on Sunday--maybe I could get a little more excited about the prospect for lowland snow. Looking behind the front--as we get into Monday and Tuesday the air will be much colder aloft but the shower activity looks light and spotty. The next front will approach the coast Tuesday afternoon but precip Tuesday night does not look like much and the heavier precip will be well south of our area. 19

LONG TERM /WEDNESDAY THROUGH SATURDAY/. The air mass might be moist enough for shower activity at times--although California looks a lot more interesting Wed and Thu. Another front or two arrive late in the week--but it is too early to say much about that other than a low snow level is likely, but nothing yet looks like a slam dunk for the lowlands. I think as time goes by, the BLI-YWL gradient will look better--if by Thursday that is up around -10mb and some genuine cold air is flowing down the Fraser, that will make the forecast a lot easier for those areas that get some colder air in place. 19

AVIATION. The next frontal system will approach the region tonight and move through the area Sunday. Current radar this evening already shows some light precipitation across portions of the Southwest Interior this evening, with ceilings at area terminals (KHQM and KOLM) already lowering down to MVFR. Current conditions at Puget Sound terminals remain VFR this evening, however expect MVFR ceilings and light rain to move in late tonight and overnight. Ceilings are likely to then lower to low- end MVFR /high- end IFR by Sunday morning and afternoon, with rain eventually turning to showers. Some snow may mix with rain or rain may change over to snow at times-the terminal most likely to experience this currently appears to be KBLI. Though, with southerly flow expected to increase across the area, this may act to hold off any rain-to-snow chances for the terminal. Will need to continue to monitor trends over the next several hours. Winds out of the S today 5-10kts, increasing Sunday 8-12kts.

KSEA . Current conditions are VFR conditions this evening, however except these to drop to MVFR overnight with light rain after midnight. Rain will taper to showers Sun morning, with ceilings continuing to fall to lower- end MVFR. Currently expect all precip to be rain through Sunday. Winds S 5-10 kts today, increasing to around 10kts Sunday.

MARINE. The next frontal system is set to move through the area tonight and Sunday. This will bring increasing winds to all area waters, with gale force winds likely over the Outer Coastal Waters and Small Craft Advisories for all other waters except Puget Sound (which will be close). Based on latest guidance, have increased winds and headlines a bit earlier than previously forecast-with winds expected to pick up after midnight. Rain and low clouds will accompany the winds, making for a dreary day tomorrow. Winds will gradually ease through the afternoon and evening tomorrow, with swells increasing to between 10-15 ft across the near-shore coastal waters and 16-19 ft further offshore. This will keep a SCA for all offshore waters and Grays Harbor Bar through at least Monday afternoon.

Unsettled (and colder) conditions will continue through next week, with periodic episodes of SCA winds and seas accompanying each frontal system. Another round of gale force winds appears possible on Tuesday for the offshore waters.

HYDROLOGY . No river flooding expected through the next 7 days.
