8/26/2020 The 7 day forecast is taking about 5 seconds to load but it will eventually load. NOAA is still working on it. 8/18/2020 NOAA continues to have trouble. Wind guest will occasionally be left off graphs. I am working with NOAA to resolve the issue. 12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

Area Forecast Discussion National Weather Service Seattle WA 854 PM PST Fri Jan 15 2021
SYNOPSIS. Dry conditions are expected for Western Washington the remainder of today and into Saturday. The next front moves through Saturday night with another round of precipitation. An upper level ridge sets up over the area early next week bringing dry conditions through Tuesday.
SHORT TERM /TONIGHT THROUGH MONDAY/. Forecast was updated this evening to indicate earlier and slightly more widespread coverage of fog tonight, as surface observations and satellite reveal formation already underway through the lower Chehalis Valley and around southern Puget Sound. Otherwise, forecast remains on track this evening. Remainder of previous short & long term sections follow below, with updated aviation, marine, and hydrology sections. Cullen
The upper level ridge responsible for this will move over the area overnight and through the day tomorrow before the next frontal system arrives Saturday night. This front is expected to be very similar to the one that just exited . fairly weak and quick to move on. A follow-up upper level ridge will be right on its heels with dry conditions expected to resume by Sunday afternoon. This secondary ridge will be slower to move through the area, keeping conditions dry all day Monday. It should be mentioned that with each one of these ridges . tonight into Saturday morning and Sunday night into Monday morning . that patchy fog will be possible.
Daytime highs in the short term offer little in the way of variation with most lowland locations reaching the upper 40s to around 50. 18
LONG TERM /TUESDAY THROUGH FRIDAY/. Upper level ridging will continue into Tuesday before a frontal system plunges into W WA associated with an upper level trough in Northern Canada. Like the fronts in the short term, this also does not particularly linger over the area . moving in Tuesday afternoon and out during the overnight hours Tuesday/early Wednesday morning. Wednesday sees a pretty minor ridge move over the area. The next system slated for Thursday continues to be the main forecast issue. Deterministic models disagree on timing although both agree that this system will bring cooler temperatures to the area. Details on storm track do not line up either. Looking at ensembles, a good case arises for said cooler temperatures . with AM temps dipping below freezing . but the chances for precip with this system . and what form that precip would take . continues to be up in the air. Not helping matters is the fact that 24 hours ago, both the ECMWF and ensembles were painting a different picture, with conditions warm enough to back away from any potential snow forecast. All that being said, confidence remains very low. Current solutions would restrict any potential snowfall for the lowlands to the Thursday AM hours and if any flakes were to be present, they would likely be mixed in with rain. By Thursday afternoon, precip would be all liquid. Solutions for this system are likely to change with each model run . so stay tuned to the latest forecasts. As the low pulls away Friday there would still be the prospect of some scattered showers in the morning, but dry conditions would resume by Friday afternoon.
As alluded to, temps during the long term will be on the decline over all, with highs Tues and Weds in the mid 40s for lowland locations before falling into the lower to mid 40s Thursday and Friday. Overnight lows will generally be in the mid to upper 30s for most lowland locations Tues night and Weds night . although some valley locations could dip down to around freezing . with most of W WA being in the lower to mid 30s Thursday night and Friday night. 18
AVIATION. Northwesterly flow aloft will gradually become more westerly on Saturday as an upper level ridge axis along the West Coast moves further inland and makes way for an approaching system on Saturday night. Satellite imagery and observations this evening already indicate the formation of fog across the Southern Sound and the along the coast, with KPWT, KOLM, and KHQM already dropping down to IFR and LIFR conditions. Overall, expect this trend to continue through the overnight hours, with a gradual decrease back down to MVFR expected for other area terminals late tonight and overnight. IFR and LIFR conditions are most likely going to persist across portions of the Southern Sound and along coastal locations, where visibilities below 1 statute mile are likely to persist through the early Saturday morning hours. Surface winds are expected to remain light and variable, at or below 5 knots.
KSEA . VFR conditions prevail this evening, however expect ceilings to decrease down to MVFR overnight (likely between 07-09Z) as patchy fog or mist settles in across the area. Conditions look to rebound to VFR again around daybreak Saturday. Surface winds will remain light, at or below 5 knots through overnight hours, generally out of the NNE.
Kristell/Borth
MARINE. Small craft conditions for hazardous seas across the coastal waters and western Strait will continue Saturday as seas continue to rise overnight. Westerly swells of 14-17 feet will be possible across the waters through early Saturday morning, before seas gradually start to subside. With high pressure and light winds over the area, conditions will favorable for fog development. As such, inland waters may be affected by reductions in visibility overnight and through the early morning hours due to fog or mist. Generally calm conditions expected across area waters through the day Saturday, before winds pick up across the coastal waters Saturday night ahead of the next system slated to move through the region. Small Craft Advisory strength westerly winds will be possible along portions of the Strait of Juan de Fuca on Sunday in the wake of the system. More headlines will be possible early next week.
Kristell/Borth
HYDROLOGY. Mostly dry conditions have helped river to continue to recede today. The higher flows continue to move through the lower reaches of the Chehalis River, with the flood warning remains in place at Porter. With the continued longer breaks between weather systems to cross the area, along with lower rainfall amounts and lower snow levels, little additional impacts to local rivers are expected. The Skokomish River may see minor rises with each system that may keep it running higher, but it is expected at this time to remain below flood stage for the next several days. 18/12
