Area Forecast Discussion National Weather Service Seattle WA 258 AM PDT Fri Aug 7 2020

SYNOPSIS. Weak high pressure will rebuild into the region today for drier conditions. A weak system will brush the region tonight and early Saturday for a chance of showers before high pressure returns for warmer and drier conditions Sunday and Monday. An upper trough will return in the middle of next week for cooler temperatures and additional cloud cover.

SHORT TERM /TODAY THROUGH SUNDAY/. There are some lingering showers early this morning, mainly over the Cascades, but these should fade away in the next few hours as weak high pressure aloft moves over the area. An upper short wave will bring some showers to the coast and north interior later this afternoon and tonight. This weather system mostly falls apart as it moves onshore tonight and most of the rest of the area probably won't get much if any precipitation. A few showers will linger into Saturday with a weak upper trough over the area but mostly it will be a dry day. Highs will be slightly below normal today and Saturday then warm to near or slightly above normal on Sunday. Schneider

LONG TERM /MONDAY THROUGH THURSDAY/. Monday is looking like the warmest day in the next week with a broad upper ridge over the area. Low level flow will remain onshore which will prevent temperatures from warming too much but highs should be in the lower to mid 80s for much of the I-5 corridor with 70s elsewhere. An upper trough will gradually carve out across the Pacific Northwest Tuesday through Thursday. It looks dry initially and the main change will be for highs to cool to near normal with a bit more cloudiness. Shower chances will gradually increase in the middle of the week with the best chances on Thursday. Schneider

AVIATION. The low level air mass remains moist with pockets of IFR to MVFR cigs across western WA. Ceilings will improve this afternoon with mainly VFR conditions expected. The flow aloft is westerly. A weak cold front will bring mostly light showers this afternoon and evening. Showers will diminish late tonight. 33

KSEA . MVFR cigs this morning then improving to VFR this afternoon. S winds to 10 kt becoming N 00-03z this evening. 33

MARINE. Winds will be generally light today and tonight as a weak cold front dissipates over the area. A stronger onshore push will likely bring Small Craft Advisory winds through the strait on Saturday. The flow will remain onshore through early next week. 33

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 . 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.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
