Area Forecast Discussion National Weather Service Seattle WA 229 PM PST Tue Jan 26 2021

SYNOPSIS. Western Washington will remain in a bit of a trough-y pattern the next few days. A series of fairly weak fronts will be associated with these troughs that move through the area. The general trend in precipitation with each of these fronts will be mostly light and scattered. After tonight, snow levels begin to rise throughout the week.

SHORT TERM /TONIGHT THROUGH FRIDAY/. Clouds ahead of the cold front that currently situated just off shore will continue to move in this afternoon. As this front moves through expect it to produce some precipitation over the area. The precipitation type is going to be very dependent on location. With temperatures in the low to mid 30s tonight for much of the lowland areas and strong easterly flow coming down from the Cascades snow accumulation is unlikely for much of the East side of the Puget Sound and Northern Inland waters. However, locations above 500 feet on the East side of the waters have a greater chance of seeing a dusting of snow overnight. With the easterly winds, some terrain enhancement of the precipitation is expected on the East side of the Olympics, including the Hood Canal area. A few inches of snow is expected above 500 feet, with more accumulation as you go up in elevation. However, there still remains some uncertainty with the snow totals in this area. It will very much depend on temperature, precipitation intensity as well as how strong those easterly winds will be in this area. Outside of the precipitation, the winds tonight will have to be monitored carefully. With a pressure gradient ~10 hPa across the Cascades the potential for some stronger winds is there. This is especially true for areas that lie within the Cascades gaps from Emuneclaw to North Bend. By mid morning Wednesday the weather is expected to be calming down and skies will be scattering out, but a few remaining scattered showers are expected to remain in place. Additionally, snow levels will begin to rise up to 1500-2000 feet by the afternoon. These snow levels are expected to stay pretty much in place for the remainder of the week, therefore, ending the lowland snow threat for awhile. The next front is expected to move through the area Thursday night. But with the main part of the trough well to our south, Western Washington is expecting mostly light scattered precipitation.

Butwin

LONG TERM /SATURDAY THROUGH TUESDAY/. This weekend we should see a little bit of warming, with high temperatures in the lowlands going to be in the mid to upper 40s. A more organized front will move through Saturday into Sunday. Rain in the lowlands and mountain snow are expected. The bulk of the precipitation is expected to be along the coast and over the Olympic Mountains. There is still a lot of uncertainty and many things can change but right now only 5-8 inches of snow are expected at the Cascade passes from Friday to Sunday night. The system to watch will be the one expected Monday into Tuesday. As models are suggesting the low will track right through Western Washington.

Butwin

AVIATION. South to southwesterly flow aloft this afternoon and into Wednesday as an upper trough approaches the area. Generally dry conditions for terminals east of the Sound this afternoon while coastal locations may already be seeing some rainfall and points west of the Sound may see precip during this time frame. Precip for terminals east of the Sound to be confined to tonight through early Wed AM. Chances on this remain underwhelming, with PoPs generally 20- 30 pct. Easterly surface flow factors in to this with a drying influence. Picture on precip type remains unchanged with best prospect for any sort of snow being north of a line running from HQM, through SHN, to BLI. Locations south of that line may still see a few flakes mixed in with the rain . should precip actually occur /which, again, chances do not favor/. Speaking of easterly surface flow, this may create some breezy to windy conditions, especially in and around mtn passes, but also impacting terminals east of the Sound, which could see some gusty conditions this evening.

Generally VFR conditions continue over W WA this afternoon although seeing some gradual lowering of cigs over the area. HQM is an exception as it is already in the midst of the passing wx system, with cigs there being MVFR. As the system moves inland, can expect other stations to dip down into MVFR, mainly those prone to lower cigs, especially with precip.

KSEA . VFR cigs into tonight. Next front expected to be mainly dry, although may see cigs dip down into MVFR late tonight/early Wed AM. Although PoPs remain in 20 pct range, any precip that does fall may be a mix of rain and flakes. No accumulation/impacts expected. Easterly winds will persist, 10 to 15 kts in advance of the front this afternoon and evening before easing back down to 4 to 8 kts tonight and Wed AM. 18

MARINE. Offshore flow will continue with speeds increasing as weather system passes through. Gales still expected for the coastal waters this afternoon through tonight with gales for the western and central portions of the Strait of Juan de Fuca already occuring at Race Rocks as per latest obs. Small Craft Advisory winds still expected for the other waters this evening and tonight as front passes through. Inherited headlines look good and will remain in place. Winds will decrease late tonight and Wednesday. Fraser Outflow possible Thursday into Thursday night. Additional fronts will move through late this week and into this weekend.

Seas of 9 to 12 feet will increase tonight to 9 to 16 feet and diminish a bit Wednesday and through the week. 18

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