Area Forecast Discussion National Weather Service Seattle WA 248 PM PDT Sat Oct 24 2020

SYNOPSIS. Winds will gradually ease this evening, giving way to the first frost/freeze of the season tonight. Dry conditions and chilly temperatures are expected to persist through Tuesday. Temperatures are expected to moderate through end of the week, with shower chances increasing once again late in the period.

SHORT TERM /TONIGHT THROUGH TUESDAY/. The latest CH-10 (7.34 um) water vapor imagery shows that drier air has settled into the region this afternoon. Scattered to broken mid level clouds remain over much of the Puget Sound and Chehalis Valley this afternoon, keeping temperatures in the upper 40s to around 50. As gradients relax over the next several hours and the sun angle gets lower, expect these clouds to scatter out and dissipate this evening, giving way to mostly clear skies tonight.

Winds have peaked across the Fraser River Valley and across the San Juans as the BLI to YWL gradient continues to gradually weaken as the low pressure system responsible for yesterday's weather pulls away from the region. Breezy conditions will persist through the next several hours, aided by decent mixing. Between a weakening gradient and the setting sun, winds will relax across the region this evening. That said, winds will not become calm tonight, which will be the limiting factor in how low temperatures drop tonight. While we are still expecting our first widespread frost/freeze of the year, light mixing will keep temperatures in the upper 20s to low 30s, as opposed to widespread mid to upper 20s. Well shaded locations that will not be able to fully dry out, as well as secondary and untreated roads, particularly in and around mountain passes will see the treat for black ice once again tonight. If you plan on traveling, use caution and check WSDOT for the latest travel information. Otherwise, be sure to protect the 4 P's tonight as temperatures fall - plants, pets, pipes and people.

Quiet weather and abnormally cold temperatures will persist into Sunday as the stout upper level ridge offshore and deepening departing upper trough to the southeast amplifies the overall synoptic pattern over the Western US. Western Washington will remain in northerly flow through the end of the period as a result, yielding highs in the 40s with lows nearing or exceeding freezing once again Sunday night into Monday morning across the lowlands. Highs will remain in the upper 40s to low 50s for Tuesday, with warmer lows in the mid to upper 30s.

LONG TERM /WEDNESDAY THROUGH SATURDAY/. High impact weather is currently not expected through the end of the period. Ensemble model guidance remains consistent today in shifting the ridge axis across the region Monday night into Tuesday as a series of shortwave troughs eject out of the Gulf of Alaska and begin breaking the ridge down. It is worth noting that there is enough variance in guidance regarding how much the ridge breaks down on Tuesday/Wednesday that will affect resultant weather across the northern interior. A fairly long fetch of moisture is progged to impact BC in this timeframe and and flatter ridge will allow some of this moisture to clip northern Washington bringing rain showers and mountain snow showers. For now, opted to keep chance POPs in the forecast. Guidance remains consistent in indicating another system approaching the region by the end of the week/next weekend. With the upper ridge axis shifting across the region, temperatures will moderate through the period, with seasonal highs and lows expected once again by midweek.

Pullin

AVIATION. Generally scattered ceilings at all terminals this afternoon with VFR conditions. Northern terminals will stay windy through much of the evening and overnight hours with residual Frasier Outflow winds, and Puget Sound terminals will be gusty into the evening, generally tapering after 03z. Wind direction continues to come out of the north/northeast overnight.

KSEA . VFR conditions expected through the evening and overnight hours with a scattered cloud ceiling through early this evening (02- 04Z), clear skies after this point. Winds will stay gusty out of the north/northeast into the overnight hours before decreasing between 08-10Z.

Kristell

MARINE. Fraser outflow has weakened over the northern inland waters and eastern Strait of Juan de Fuca, with Small Craft Advisory level winds in the wake of the Gale Warning. Elsewhere, small craft advisories remain in effect today with breezy north winds through Puget Sound and northeast winds over the coastal waters. Advisory winds for the outer coastal waters have been extended into Sunday morning. Additionally, the Small Craft Advisory for the central and eastern Strait of Juan de Fuca has been extended into Sunday morning. Seas over the coastal waters have decreased, and will likely not become as steep as the dominant period has lengthened. Kristell

HYDROLOGY. Flooding is not expected through the next 7 days.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
