Area Forecast Discussion National Weather Service Seattle WA 821am PDT Sat Oct 5 2024 No major forecast updates this morning. Areas of fog continue to remain across the valleys in the Southwest Interior, Kitsap Peninsula, and in some of the river valleys including the Chehalis and the Snohomish/Snoqualmie. Fog should break out quickly in the next hour or two, leaving mostly sunny skies with high clouds to the northwest as a front passes by into British Columbia. Light offshore flow should allow temperatures to rise into the 60s today. See the previous discussion below, as well as updates to the aviation and marine sections. LH Synopsis Patchy fog and low clouds are developing in portions of western Washington this morning as high pressure builds back into the region. Slightly warmer temperatures are forecast for today and Sunday, likely peaking on Monday. Rain chances then return for the middle of the week. Short Term - Today through Monday Fog and stratus is developing across the central and southern Sound region, as well as some in the Southwest Interior. This will be a feature that lingers through much of the morning before scattering out, revealing a mostly sunny afternoon with highs in the mid to upper 60s. Similar temperatures are forecast for Sunday, with highs likely peaking in the low 70s by Monday. The upper level pattern shows the present ridge nudging east on Monday, keeping a chance of rain in the forecast for far northwestern Washington. The majority of the region should likely only see light rain amounts at about a tenth of an inch or less, with only up to a quarter inch expected in the windward slopes of the Olympic mountains. Long Term - Tuesday Through Friday Agreement in the cluster analysis is solid for Tuesday, showing the trough moving through Washington, with the ridge well established over the Intermountain West. Only a few light showers are likely to remain on Wednesday, quickly scattering out. As the ensembles move out to Thursday and into Friday, the location of the ridge axis over the west will be key in determining how zonal or not the flow will be in western Washington, and whether or not this will fully close off the region from receiving additional precipitation in the late week timeframe. If the Climate Prediction Center's 6 to 10 day and 8 to 14 day outlooks are any indication of the extended pattern, more significant probabilities of above average temperatures and below average precipitation are favored. This is the case for a large swath of the CONUS, prolonging drought and fire weather concerns over other parts of the west. Marine A surface ridge will shift inland today turning the flow northerly or weakly offshore tonight into Sunday. A dissipating cold front will approach the coastal waters Sunday night into Monday with an increase in southerlies for portions of the coastal waters, but otherwise little to no impact. Latest forecast suggests that SCA (Small Craft Advisory) level winds may be possible, but at this time appears to be a very borderline situation. At this time, will leave any headline decisions to next shift in the hopes future model runs will provide better clarity. Another weak system may follow Tuesday into Wednesday, but confidence in the overall forecast picture by that time period is low. 18/27 NOAA Seattle WA Office: Watches - Warnings - Advisories WA...None. PZ...None. |
