SYNOPSIS. Western Washington will have cooler weather and clouds with marine air in onshore flow today. A weather system will bring cool weather and precipitation to the region over the weekend. Weak high pressure might build over the region for the first part of next week before another period of wet weather begins.
SHORT TERM /TODAY THROUGH SATURDAY/. An upper trough is east of the area with weak surface low pressure over WA. Onshore flow into Western Washington will give cooler weather and clouds today. Friday will also have a deep marine layer over the area for cloudy cool weather. A weather system will arrive Saturday with periods of rain turning to a more showery precip Saturday night. Expect much cooler temps with high temps only forecast to be in the lower to mid 50s on Saturday. 19
LONG TERM /SUNDAY THROUGH WEDNESDAY/. Cool showery weather on Sunday might give way to a couple of days that see more in the way of sunbreaks and high temps across the lowlands of Western Washington near 60 degrees--and perhaps warming to the lower to mid 60s around Tuesday of next week. There might be a bit of a ridge building into the area for a couple of days--so there might very well be some room to improve the forecast for a couple of days next week before another upper trough arrives after the middle of the week. 19
AVIATION. Northwest flow aloft continues over Western Washington today with an upper ridge over the offshore waters and an upper trough over the northern Rockies. Low level onshore flow has pushed marine moisture inland across the lowlands of Western Washington. IFR or low MVFR ceilings in stratus are expected through late morning. Stratus is expected to scatter our across the interior by 20Z-21Z, but should persist near the coast. VFR expected across the interior into this evening, but clouds will increase late tonight as a weak frontal system approaches the region.
KSEA . IFR or low MVFR in stratus through 19Z then ceilings gradually lifting to VFR around 21Z. VFR expected mid afternoon through late tonight with ceilings lowering again tonight ahead of approaching weak frontal system. Surface winds S-SW generally under 10 knots. 27
MARINE. Onshore flow weakens somewhat today as a weak surface trough slips southward along the Washington coast this morning then shifts inland late this afternoon. Onshore flow remains relatively light into Friday as weak trough offshore gradually moves toward the north Oregon coast Saturday afternoon. Another weak trough arrives on Sunday but again produces little in the way of significant wind. A weak surface ridge is expected to slide eastward across the waters on Monday. A more significant frontal system could affect the waters by Tuesday or Wednesday of next week, but confidence is not high at this time. 27
HYDROLOGY. No river flooding expected the next 7 days.
