Area Forecast Discussion National Weather Service Seattle WA 750 PM PDT Fri Aug 14 2020

UPDATE. The forecast is still on track this evening and no major changes have been made. Only a few changes to the aviation and marine discussion found below.

SYNOPSIS. High pressure aloft will bring much warmer temperatures this weekend with Sunday on track to be the hottest day for interior locations. After Sunday, temperatures will be on the way back down to normal. A few showers are possible by the middle of the week as a weak trough moves through.

SHORT TERM /TONIGHT THROUGH MONDAY/. An upper ridge will build over the area this weekend with low level flow turning more northerly or even light offshore. This will allow temperatures to warm significantly. Highs will be mostly in the 80s on Saturday with lower 90s possible for the south interior and Cascade valleys. Sunday will be the hottest day for the interior with highs in the 90s commonplace and a few locations near 100.

There will be increasing south/southwest flow aloft on Sunday as the upper ridge axis shifts inland. This will open the door to a small shower threat for the Cascades Sunday afternoon and night. Any thunder threat appears to stay to the south and east of the area but there is a small, non-zero chance of some thunder over the Cascades during this time that will need to be monitored.

The upper ridge axis shifting inland will also allow for increasing low level onshore flow later Sunday and Sunday night. It will be hot for the interior as mentioned above but a flow reversal is likely at the coast with cooler temperatures. There should be a marine push Sunday night with stratus at the coast and partially inland Monday morning. Highs will cool on Monday, ending the impactful heat, but still be in the 80s for the interior.

There will also be fire concerns this weekend. Please see the fire weather section below for more details. There could also be some smoke coming up from the south Saturday night and Sunday but the extent of this is uncertain for now. Schneider

LONG TERM /TUESDAY THROUGH FRIDAY/. An upper trough will cross the area Tuesday and Wednesday with temperatures cooling to near normal by Wednesday. There could also be a few showers with the upper trough but mostly it looks dry. A weak ridge will build over the area Thursday and Friday with highs rising to slightly above normal. Schneider

AVIATION. Upper level ridge over the area with northwesterly flow aloft becoming southwesterly Saturday. Low level onshore flow tonight becoming northerly Saturday.

Clear skies across the area with the exception of some late night and morning patchy low clouds along the north coast.

KSEA . Clear skies. North winds 5 to 10 knots becoming northeast 4 to 8 knots after 06z. Felton/Kristell

MARINE. Low level onshore flow tonight will turn northerly Saturday. The flow will go briefly offshore Saturday night into Sunday morning before turning back onshore Sunday afternoon. Varying degrees of onshore flow will continue Monday through the middle of next week.

Small craft advisory north to northwest winds in the inner coastal waters tonight. Small craft advisory northerly winds developing in Puget Sound and Hood Canal Saturday afternoon then ease late Saturday evening. Felton

FIRE WEATHER. The Fire Weather Watch for the Cascades and Black Hills/Southwest Interior lowlands Saturday morning through Sunday evening has been upgraded to a Red Flag Warning. The Southeast Puget Sound Lowlands were also added to the warning.

Hot, dry and unstable conditions are forecast this weekend with temperatures reaching the 90s to near 100 Sunday and min humidities in the mid teens to 20s. Mid-level Haines will also reach a 6 or high potential for large fire growth. There is a small chance of thunder (around 5%) over the Cascades Sunday afternoon and evening.

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 . Red Flag Warning from 11 AM Saturday to 11 PM PDT Sunday for Black Hills and Southwest Interior Lowlands-Southeast Puget Sound Lowlands Generally Below 1500 Feet-West Slopes of the Central Cascades Generally above 1500 Feet-West Slopes of the North Cascades Generally above 1500 Feet.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
