Area Forecast Discussion National Weather Service Seattle WA 849 PM PDT Tue Aug 16 2022

SYNOPSIS. A strong ridge of high pressure will build into the Pacific Northwest over the next several days. This will provide well above temperatures with highs well into the 90s in many areas. The hot weather will continue for a few days before the upper level ridge shifts east by the weekend with temperatures dropping back closer to normal.

SHORT TERM /TONIGHT THROUGH FRIDAY/. A quiet evening weather wise across Western Washington. Under mainly clear skies this evening temperatures remain still in the 60s and 70s. Expecting a comfortable night with lows into the 50s to low 60s overnight. The warming trend will be noticed tomorrow, however, as highs should be some 5-10 degrees warmer than today. This will give a decent run at 90 degrees in the Seattle metro area, probabilities for Seattle remain around 25% for a high of 90 or higher. So the forecast remains with an expected high in the upper 80s, but much hotter especially across the interior valleys of the Cascades where temperatures will reach well into the mid and upper 90s. 850mb temps around 18C this evening will warm all the way to the 20-25C range by late tomorrow. Fortunately there is no strong offshore wind component to drive temperatures even higher this time. Heat Advisories and Excessive Heat Warnings remain in effect for the next couple days.

Thursday looks to be the hottest day in the interior with high temperatures in the low 90s in the Central Sound and even mid 90s South of the sound. The hottest locations will be the Cascade valleys where temperatures will hover in the upper 90s and even close to 100.

Guidance shows some mid-level instability within the Cascade mountains, and some ensembles are picking up on traces of a thunder threat. Confidence is low on any storms firing off due to the lack of sufficient moisture in the region, but if anything does indeed form, it will be super high based and likely will not last long.

Conditions look to cool down 5 to 10 degrees on Friday as the ridge axis moves eastward and an upper level trough nears Western Washington. The marine layer will deepen and in conjunction strengthening the onshore flow, providing a cool down into the weekend.

Johnson/Mazurkiewicz

AVIATION. Upper level ridge over the area. Light flow aloft becoming southerly Wednesday morning. In the lower levels light onshore flow through Wednesday.

Clear skies over the area tonight with stratus offshore. Stratus moving to the coastline around 09z but not making it very far inland. Ceilings with the stratus less than 1000 feet. Stratus retreating back off the coast 16z-18z. Clear skies for the remainder of the area through Wednesday.

KSEA . Clear skies. Northerly wind 4 to 8 knots increasing to 8 to 12 knots around 22z Wednesday. Felton

MARINE. Onshore flow continues over W WA waters as high pressure influences the coastal water zones and lower pressure continues east of the Cascade Crest. Winds will remain rather benign over the waters tonight.

Weaker onshore flow/marine pushes Wednesday and Thursday will keep the greatest extent of the stratus over the coastal waters. This will also result in either the absence of, or very marginal westerly small craft advisory level winds down the Strait.

Onshore flow will then strengthen Friday and into the weekend, with stronger pushes each evening down the Strait. Models remain consistent in putting Small Craft Advisory winds for the Strait during this timeframe and possibly spilling over into the adjacent waters of Admiralty Inlet and the Northern Inland Waters. Seas through the forecast period will generally remain 3-5 feet near the Coast and offshore and 1-2 feet in the interior waters (2-4 feet in the Strait during small craft advisory level winds).

FIRE WEATHER. Hot and dry conditions continue to develop the next few days. This, in combination with receptive fuels and very unstable (Haines 6) conditions lead to critical fire weather conditions in the Cascades the next few days. As a result, have issued a Red Flag Warning for zones 658 and 659 for Wednesday and Thursday. There may be some modest, but generally poor recoveries across the zones Wednesday night. Elsewhere across the lowlands, expect that some marine influence will yield better recoveries and somewhat higher daytime RHs above critical values. The adjacent foothills zones (specifically: 656, 657, and parts of 655), however, may approach critical values, so will have to closely monitor the forecast in these areas. The next fire weather concern would be the potential for thunderstorm activity. There's some slight chance that late Thursday could see some monsoonal moisture work north to near the crest, but this does not look favorable at this time. A better chance would be around Sunday with the breakdown of the upper ridge. Cullen

HYDROLOGY. The daily hydrology discussion has ended until the start of the next rainy season; it will only be updated as needed.

PREV DISCUSSION. /issued 307 PM PDT Tue Aug 16 2022/

LONG TERM /SATURDAY THROUGH TUESDAY/ . Temperatures go back to near seasonal normals for the weekend as upper heights begin to fall due to the approaching upper level trough in our region. With this trough, unstable southerly flow will be present throughout the weekend. Ensembles are continuing to trend more on the dry side for now, but the pattern does look favorable for some convection Sunday through Monday in the mountains. Will need to continue to monitor the trend for any potential changes.
