Area Forecast Discussion National Weather Service Seattle WA 900 AM PST Wed Feb 24 2021
SYNOPSIS. A break in the weather today will be short-lived and the next front will reach Western Washington tonight. Strong onshore flow will give periods of heavy mountain snow Thursday and Friday. There will be a break in the weather on Saturday. A weak warm front will reach the area Sunday followed by a cold front Sunday night.
SHORT TERM /TODAY THROUGH FRIDAY/. Most of Western Washington will have sunshine today after some areas of morning low clouds and fog. High clouds will increase, highs will be in the 40s. The next front will reach Western Washington overnight, with a fropa around daybreak. There are gale warnings and wind advisories in the normally windier spots. A winter storm watch is up for the Cascades, and periods of heavy mountain snow are likely from Thursday morning through Friday night. And with westerly flow in the wake of the front we ought to see the convergence zone wax and wane. Seas could build to around 20 feet along the coast by daybreak Friday. 19
LONG TERM /SATURDAY THROUGH TUESDAY/. Showers from the aforementioned system will linger into early Saturday, before tapering. Conditions then look to dry as upper level ridging traverses the region. There remains uncertainty in deterministic and ensemble guidance regarding the extent of the drier weather, however, as guidance does indicate some weaker systems riding the ride and making their way into the area by early next week. Have kept a chance of POPs in the forecast, however will have to see how the forecast evolves over the next several days. 14
AVIATION. High pressure and offshore flow will bring dry and stable conditions to western W today. The flow aloft is northerly. Low clouds and fog are mainly near Puget Sound this morning but will scatter and erode this afternoon for VFR conditions. Rain with our next system will reach the coast after 06z tonight then spread inland by 12z. Gusty S/SW winds expected through Thursday with this system. 33
KSEA . Low clouds in the vicinity this morning with possible MVFR cigs, then becoming VFR this afternoon. Winds generally 5 kt or less. 33
MARINE. Seas will remain around 10-14 today over the Coastal Waters and West Entrance. Otherwise, expect generally light offshore winds as high pressure moves in.
Southerly flow will increase tonight ahead of our next incoming system. This system will likely bring gales on Thursday with another strong onshore push Thursday night. Strong post-frontal onshore flow will continue into Friday with seas building to 20-25 feet. Winds and seas will ease/subside over the weekend. 33
HYDROLOGY. The lowest reaches of the Chehalis River have continued to rise overnight, so have kept the flood watch for Grays Harbor County going. The crest at Porter may be very close to flood stage late this morning, but is expected to gradually recede throughout the remainder of the day. Additional precipitation arrives tonight into Thursday, but with modest amounts and relatively low snow levels, no additional river flooding is expected at this time. 14
