| Area Forecast Discussion National Weather Service Seattle WA 813am PDT Wednesday July 6 2022 Synopsis An upper level low will remain offshore through Thursday, allowing for showery weather to persist across Western Washington. Drier conditions resume on Friday as the low moves into British Columbia. A weak disturbance then looks to brush the region over the weekend before an upper level ridge builds into the region early next week and brings dry weather and warming temperatures. .UPDATE /TODAY/...Scattered showers continue to move north across the area this morning. Most are light in nature, though an occasional heavier shower has been noted. No change to the overall forecast this morning. Isolated thunderstorms will be possible over the Cascades and foothills. A stray thunderstorm in the lowlands cannot be ruled out, but the chances there are generally less than 10 percent. Will continue to monitor and update as needed. -Wolcott- Short Term - Today through Friday An upper level low will remain offshore through Thursday, bringing continued chances of shower activity through much of the short term period. Radar shows scattered showers moving northward across Western Washington as of 2AM/9Z. Overall, expect shower activity to continue to move northward across the forecast area through the day today. A slight chance of thunderstorms remains possible, primarily along the Cascades and the adjacent foothills, as the airmass becomes more unstable this afternoon and evening. Afternoon high temperatures today will be in the upper 60s to low 70s across the interior and in the low to mid 60s for areas along the coast. Shower activity will continue into Thursday, before tapering late Thursday into Friday as the upper level low starts to move inland into British Columbia. Temperatures Thursday and Friday will be in the upper 60s to mid 70s for the interior and in the mid to upper 60s for areas along the coast. Areas of patchy fog will be possible on Friday morning given ample moisture in the low levels and continued onshore flow. 14 Long Term - Saturday Through Tuesday A weak disturbance looks to clip the area over the weekend as flow aloft becomes more zonal across Western Washington. While the majority of the forecast area looks to remain dry, we may see a few showers brush the far northern portions of the area on Sunday. Temperatures over the weekend will remain near normal, generally in the low to mid 70s across the interior and in the mid to upper 60s along the coast. Both ensemble and deterministic guidance then suggest an upper level ridge building into the region early next week. With mid level heigheights climbing across Western Washington, expect an increase in temperatures to above seasonal norms. While there is still quite some spread amongst ensemble guidance, the latest NBM 4.1 guidance does suggest about a 65 to 75 percent chance of temperatures climbing above 80 degrees for areas south of the Sound by Monday and a 75 percent chance of temperatures climbing above 80 for areas Seattle southward by Tuesday. 14 Marine Fairly weak surface pressure gradients the next few days will maintain light winds over the coastal waters with a few passing disturbances enhancing the onshore flow through the Strait of Juan de Fuca. This will lead to winds increasing to around 20 to 25 kts tonight, and again during the next few evenings. While latest guidance has trended slightly weaker for tonight's push, have elected to maintain the current advisory. Meanwhile, seas will hold around 2 to 4 ft over the coastal waters into the weekend. A return of northerly winds appears likely late in the week as high pressure rebuilds over the waters. Mazurkiewicz Hydrology The daily hydrology discussion has ended until the start of the next rainy season; it will only be updated as needed until then. NOAA Seattle WA Office: Watches - Warnings - Advisories WA...None. PZ...Small Craft Advisory from 5pm this afternoon to 11pm PDT this evening for Central U.S. Waters Strait Of Juan De Fuca- East Entrance U.S. Waters Strait Of Juan De Fuca. |
