Area Forecast Discussion National Weather Service Seattle WA 306 PM PDT Thu Jul 29 2021

SYNOPSIS. With an upper level ridge continuing to build into the area, temperatures are expected to be in the upper 80s to low 90s for much of the region. There is a chance of thunderstorms Friday and Saturday along the Cascade Crest. A cool down, and a return to what has been the weather pattern for the entire month of July at the start of next week. Towards the end of our forecast period we will be watching a low pressure system that may bring some rain to the area.

SHORT TERM /TONIGHT THROUGH SUNDAY/. While low temperatures tonight are expected to be in the upper 50s to low 60s tonight, the highs for Friday are expected to reach the low to mid 90s for the Interior lowlands on Friday, with hotter conditions in some of the exposed valleys likely. Not much relief is expected to occur Friday night/Saturday morning with lows expected to be in the upper 60s. As a result, a Heat Advisory has been issued for a large portion of the forecast area. Inland areas that are not included in the Advisory will still experience hot conditions (unless at high elevation), but with some light onshore flow continuing these areas will feel a little more relief.

There is also the chance of some scattered thunderstorms both Friday and Saturday in the Cascades. Conditions for thunderstorm development are more favorable Saturday with high instability.

With the upper level ridge shifting westward the southerly flow aloft as the potential to bring some smoke from fires to our south into the area. This smoke is expected to remain well above the surface but could create for some hazy skies. If new fires were to start closer to our area, there would be the potential for low level smoke and decreased AQ. But at this time we do not foresee any air quality issues.

Sunday we expect to return to the same weather pattern we have had for this entire month with high temperatures in the low to mid 80s and lows in the upper 50s for the Interior. The coast will remain nice and comfortable with highs in the 70s. There is the slight chance for some light rain showers mostly in the Cascades as the upper level ridge is forced eastward.

Butwin

LONG TERM /MONDAY THROUGH THURSDAY/. For the start of the long term expect the same weather we have had all month. Dry, warm, nightly marine pushes, with morning clouds likely. Thursday, there is the chance that an incoming low pressure system and cold front could give us some widespread precipitation. However models are still feeling a little conflicted about this.

Butwin

AVIATION. The air remains warm and dry except for shallow marine low clouds and fog along the coast and in parts of the western Strait of Juan de Fuca. We will probably see a few cumulus buildups over the mountains late this afternoon and the air mass on Friday will be more unstable with the chance of thunderstorms spreading north into the Cascades as a little bit of moisture starts to work north in southerly flow aloft.

KSEA . Clear with a northerly breeze.

19

MARINE. The core of thermally induced low pressure remains east of the Cascades. The evening westerlies in the Strait will be stronger Saturday evening with westerly gales possible as pressures fall east of the Cascades and marine air pushes into Western Washington.

19

FIRE WEATHER. An upper level ridge will strengthen across the region and continue to promote warm and dry conditions across Western Washington Friday and into the weekend. This will continue to promote further drying of area fuels, with much of the area's fuels gradually narrowing in on their 90th percentiles. Weak onshore flow will continue in the low levels, however strengthening inversions could lead to more modest RH recoveries across the mountains this weekend. Min RHs look to dip down into the 25-30% range for the Cascades and portions of the southern interior- mainly from Olympia southward on Friday. Northerly winds look to also pick up at times during the afternoon hours on Friday, however do not expect winds to remain elevated for a long duration of time. In addition, a slight chance of thunderstorms will be possible for areas across the Southern Cascades on Friday and along the entirety of the Cascade crest on Saturday. Thus, brief localized red flag conditions will be possible for portions of the Cascades and southern interior Friday into Saturday, but are not expected to be long- lived or widespread at this time. Conditions will need to continue to be monitored going forward.
