Fxus66 ksew 210954 afdsew area forecast discussion national weather service seattle wa 254 am pdt Wed aug 21 2019 Synopsis A cold front will bring rain to the region today. Expect dry weather by Thursday afternoon with a weak high pressure over the area. A series of systems will pass generally to our north Friday into the weekend keeping temperatures near normal and bringing a chance of showers mainly to the coast and northern areas. Warmer and drier conditions are expected to develop early next week. Short term today through Friday Light rain ahead of an approaching frontal system has spread onto the coast early this morning. There is a distinct lack of cloud cover from the central puget sound southward as of 2 am pdt, but that is expected to abruptly change as we approach sunrise this morning. The models have backed off with QPF with this system as it loses steam bumping up against a broad ridge over the western us. Nonetheless, some light rain will spread into puget sound by midday with the front as it moves through. For north king and snohomish counties, the best shot of precipitation may actually be with a brief convergence zone that is expected to develop behind the front this evening. High temperatures will be considerably cooler across the interior today with 60s to near 70 common. The front will shift east of the area tonight with shower activity lingering... Especially around the convergence zone. That activity will dissipate by daybreak Thursday as post-frontal onshore flow relaxes and upper level ridging begins to build back into the area. We should see a return of some sunshine by mid or late afternoon Thursday with high temperatures returning to near normal. Upper level ridging will flatten by Friday as the first of a series of systems pass by mainly to the north. It may produce an increase in high and mid clouds later in the day Friday, but most areas should see a partly sunny day with temperatures similar to those of Thursday. Long term Saturday through Tuesday Another system moves to the north on Saturday. While still rather weak, heights will fall further and there will be a chance of showers for the coast and the interior from seattle northward. Partly to mostly cloudy conditions are expected with temperatures a little below normal. Sunday looks much the same as the last in the series of upper level disturbances passes through british columbia. And this is where things begin to change. For much of the past few weeks, the longwave pattern has favored upper level troughing to our west and a broad ridge over the interior west. As the trough over british columbia pushes eastward early next week, it is expected to carve out a decent trough over the northern plains states. In response to this, a fairly high amplitude ridge is expected to develop over the pacific northwest with 500mb heights well into the 580s Tuesday and beyond. In addition, a thermal trough may develop along the coast with low level flow turning offshore. The models have been hinting at this for a couple days now. It is still several days out, but we may be looking at at least a few very warm days to close out the month of august. Summer isn't over yet... Meteorological or astronomical. 27 Aviation An upper trough and an associated weakening frontal system will move through the area today. Weak high pressure aloft

will build over the area tonight. The flow aloft will be westerly. Low level southerly flow ahead of the front will turn westerly behind the front. The air mass is moist and stable. Clouds will increase across the area today with lowering ceilings as a front moves onshore. Low clouds will persist at the coast. The interior should see increasing mid clouds at first this morning then low clouds will become widespread this afternoon and evening. A weak puget sound convergence zone is possible tonight. Ksea... High clouds early this morning. Mid clouds will develop later this morning and then low clouds this afternoon. Low clouds should persist tonight. Southerly wind 4-8 knots. Schneider Marine A weakening front will move onshore today with small craft advisory strength southerly winds. Onshore flow behind the front will bring small craft advisory strength westerly winds to the outer coastal waters and for the central and eastern strait of juan de fuca tonight. Winds in the strait will ease late tonight. Winds over the outer coastal waters will ease Thursday but there will probably be another round of small craft advisory strength west to northwest winds for the coastal waters Thursday evening. There will also be some 10 to 11 foot seas over the outer coastal waters on Thursday. An onshore flow pattern will continue Friday and into the weekend with the usual diurnal small craft advisory strength west winds in the strait each evening. A weak frontal system will approach the area on Friday and then dissipate over the area on Saturday. The main impact will be to turn the winds a bit more southerly but speeds should remain sub-advisory strength. Schneider Hydrology The daily hydrology discussion has ended until the start of the next rainy season; it will only be updated as needed until then. Sew watches warnings advisories Wa... None. Pz...

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.
