SYNOPSIS. A front will move through Western Washington today. A warm front will arrive Thursday evening. Wet weather through the end of the week with the potential for river flooding Friday and Saturday. A cooler and drier air mass will arrive early next week.

SHORT TERM /TODAY THROUGH FRIDAY/. Radar early this morning shows rain moving across the coastal waters and onshore as the next front approaches. The front will slide east through today with the steadiest rain east of the Puget Sound by mid-afternoon. Breezy conditions this morning as the front moves through, especially for northern areas and the coast with 850mb winds 45-50 knots. Snow levels through today will be around 3500 feet this morning, rising to 4000 feet this afternoon. Winter Weather Advisory is in place for the Cascades above 4000 feet for amounts of 6-11 inches through today. Snoqualmie Pass may start as snow, mixing by later this morning with rain by afternoon. Drier weather expected by this evening through tonight as upper level ridging builds over Western Washington. Temperatures today will be in the upper 40s to low 50s.

Dry weather through Thursday morning as the upper level ridge over the area slides east. A frontal system will move onshore Thursday afternoon and be the initial front for a rather wet weather pattern, at least into the weekend, with an atmospheric river setup over a portion of the Pac NW. Steady rain Thursday evening into Thursday night with a front draped over the area. A warm front will slide north through the day on Friday for rain, heavy at times, across Western Washington. There is a degree of uncertainty as to the northern extent of the front by late Friday, and where the heaviest precipitation will be oriented. This will be a major role in the magnitude of any potential flooding event. In general, the heaviest rainfall by later Friday will be across the northern tier, from the Olympic Peninsula to the North Cascades. The frontal system will begin to slide south by later Friday night. Snow levels around 4000 feet on Thursday will rise to 6000-7000 feet by Friday. Temperatures on Friday will be in the mid to upper 50s with rather breezy southerly winds as the front is draped to the north and an elevated pressure gradient. JD

LONG TERM /SATURDAY THROUGH TUESDAY/. The front will move south across the area on Saturday with heavy rain at times. Rivers will rise Friday and Saturday, highlighting the flooding potential into the weekend. Snow levels on Saturday will lower considerably heading into Saturday night as cold air works into the Pacific Northwest. Snow levels by Sunday morning will be around 1000 feet if not lower. Guidance suggest a decent amount of uncertainty as to the extent precipitation is around Sunday into Monday with lower snow levels. At least the chance for light rain/snow showers Sunday with a cold upper trough. Upper level ridging begins to build into the area by Monday into Tuesday with at least a slight rise in temperatures. JD

AVIATION. Southwesterly flow aloft becoming westerly behind the front this afternoon and remaining westerly into Thursday. Rain out ahead of the front reaching the coast around 12z spreading inland to the Cascades by 18z. Ceilings improving out ahead of the front with a scattered to broken layer around 4500 feet with an overcast layer around 7000 feet. Isolated ceilings below 1000 feet continuing over the Kitsap peninsula until 15z. Ceilings lowering ahead in the afternoon behind the front to 1000-2000 feet with possible ceilings below 1000 feet near a Puget sound Convergence Zone in Snohomish county. Ceilings lifting back up into vfr for the evening hours before settling back down to MVFR Thursday morning.

KSEA . Ceilings around 7000 feet lowering back to to near 3500 feet with the onset of rain around 15z. Ceilings lowering again in the afternoon down to 1000-2000 feet with and behind the front with some improvement in the evening hours before ceilings settle back down to near 1500 feet Thursday morning. Southerly winds 6 to 10 knots increasing to 10 to 15 knots midday. Winds easing and becoming southeasterly tonight. Felton

MARINE. Another front will move through the waters today with gale force winds along the coast and small craft advisory winds over the remainder of the waters. High pressure will build over the area tonight then shift east Thursday morning as the next front arrives Thursday afternoon and evening for another round of possible gales on the coast and over the Northern Inland waters and small craft advisory winds over most of the rest of the waters. The active weather pattern will continue with a series of systems moving through the area Friday through the weekend. Felton

HYDROLOGY. The river forecast keeps the Skokomish river in Mason county above flood stage Wednesday and Thursday and other rivers may join it above flood stage Friday and Saturday. It is hard to say whether most of the heavy rain will fall over southwest B.C. or whether the rainfall over Western Washington will be heavy enough to cause minor problems, or perhaps more extensive river flooding so stay tuned.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
