Area Forecast Discussion National Weather Service Seattle WA 229 AM PDT Tue Apr 7 2020

SYNOPSIS. Dry and warmer weather will continue through Thursday. Weak low pressure systems may skirt the area late in the week or over the weekend.

SHORT TERM /TODAY THROUGH THURSDAY/. The main story through Thursday is going to be gradual warming up to the low to mid 60s across the CWA thanks to building offshore high pressure. Onshore flow will be light, but may result in some AM clouds on today, dissipating as the day progresses. Mostly clear on Wednesday, with temperatures continuing up a few degrees. Thursday is still going to be the warmest day of the week, with an expected high of around 64 degrees.

LONG TERM /FRIDAY THROUGH MONDAY/. Deterministic runs of both the GFS and ECMWF have gained some more agreement in regard to precipitation chances late this week and into the weekend. Both are still generally holding precipitation off until Saturday, perhaps more focused in the higher terrain. POPs are still in the forecast to reflect this.

Additionally, both runs of the model appear to bring a shortwave trough feature intruding into the periphery of the ridge across the area by Monday. At this stage, it appears that precipitation could be slightly more widespread but not exceptionally heavy or impactful.

After the slight disruption to the ridge pattern over the weekend and early next week, it appears that ridging returns, which could return some afternoon highs to the upper 50s to mid 60s depending on how much it can build in that timeframe. At least until the next system eventually comes through the area . yet the extended time frame is generally suggesting drier, more spring-like conditions.

Kristell

AVIATION. Northwest flow aloft as high pressure remains in control. Stratus near the coast may continue to push inland this morning with areas of MVFR cigs possible for a brief period. Any stratus will dissipate by early afternoon, giving way to just some high clouds.

KSEA . Mainly VFR conditions through the period. Some stratus may reach the terminal briefly this morning, but confidence in this occurring is not high. Light winds continue.

CEO

MARINE. Onshore flow continues today. Small craft advisory westerlies through the Strait will ease this morning. Flow will turn more offshore by midweek, with onshore flow returning late in the week. At this point, looks like light flow -- not enough for any headlines.

CEO

HYDROLOGY. No river flooding is expected over the next 7 days.

SEW WATCHES/WARNINGS/ADVISORIES. WA . None. PZ . Small Craft Advisory until 5 AM PDT early this morning for Central U.S. Waters Strait Of Juan De Fuca-East Entrance U.S. Waters Strait Of Juan De Fuca.

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.
