Synopsis for the southern washington and northern oregon coast - High pressure will persist over the region with a thermally induced low over california/oregon and the great basin. This will result in hot and dry conditions along with north to northwest winds pattern through the remainder of the week.

Area Forecast Discussion National Weather Service Seattle WA 756 PM PDT Tue Jul 2 2024

SYNOPSIS
A warming trend with dry conditions is expected through this weekend. Hot conditions with temperatures reaching the upper 80s and 90s across much of the region by this weekend.
These warm and dry conditions will also result in elevated fire weather concerns by the weekend. Slight cooling is possible next week.

UPDATE
Sky coverage remains mostly clear (with a few bands of cumulus remaining in the Cascades and Puget Sound this evening.
Coastal stratus will push in again for Wednesday morning with some moisture before conditions rapidly warm up and dry out by the end of the week and this weekend. Please see discussion below for more details (also updated aviation and marine sections).

HPR

SHORT TERM /TONIGHT THROUGH FRIDAY/
A ridge of high pressure over the eastern Pacific will strengthen and very slowly shift east through Thursday night before stalling with its axis along/just offshore of the Washington coast on Friday. This synoptic progression will lead to a warming and drying trend across the western US, including western Washington. Conditions will seem relatively pleasant through about the 4th before things start to get hot Friday. By Friday, high temperatures will reach well into the 80s across the lowlands north from Seattle northward, and into the low to mid 90s for some areas of SW Washington. HeatRisk levels will reach widespread moderate/orange levels by Friday.

LONG TERM /SATURDAY THROUGH TUESDAY/
On Saturday and Sunday the ridge axis will move overhead, likely resulting in the warmest temperatures of the period. Temperatures will reach the upper 80s and 90s across much of the region. At this time, the probability of reaching 100 degrees is low across most of the region, however the Chehalis River Valley does have probabilities ranging from 30-40% near Chehalis to 50-70% near Elma. Overnight low temperatures will hover in the low 60s across most of the region.
These conditions will result in widespread HeatRisk levels of at least moderate/orange with some favored areas (such as urban heat islands and the western slopes of the Cascades and Olympics)
reaching major/red. Compared to the forecast from 12 hours ago, there was a slight increase in the temperature forecast from Sunday night into Monday due to some consensus that the ridge may favor a slower eastward progression early next week. This resulted in the highest HeatRisk across the bulk of the area on Sunday (vs Saturday previously). For this event, we will no doubt see hot temperatures and heat-related impacts across the region. However, we are not in the center of this heat event (that will be further south and east of us) and as such at this time we are not anticipating impacts on the level of the 2021 "Heat Dome" event.
Still, this level of heat can result in multiple heat-related illnesses for those without access to adequate cooling or hydration.

Weak onshore flow may develop Sunday into early next week, allowing for a gradual cooling trend. However, temperatures are forecast to remain well above normal through much of next week.

AVIATION
N to NW flow aloft over western WA today with strong high pressure anchored offshore. Conditions mostly VFR except for along the coast where stationary low clouds have lingered throughout the day, resulting in MVFR cigs there. More widespread MVFR conditions expected to develop overnight with most terminals reaching MVFR by 12-15Z Wednesday morning. A return to VFR skies is expect by early afternoon...with locations more prone to lower cigs holding off until mid afternoon.

KSEA...VFR conditions persisting this evening and into the overnight period. MVFR conditions expected to develop around or a little after 12Z and persist through late morning. VFR conditions return by 20Z.
Southwest to westerly winds this evening at 4-8 kts, becoming light and variable overnight. Westerly winds 5-10 kts expected Wednesday afternoon.

MARINE
Westerly winds in the Strait and northwesterlies over the outer coastal waters still reaching Small Craft Advisory levels and as such will leave inherited headline in place. Winds will turn more N to NW on Wednesday as strong high pressure shifts toward Vancouver Island. The flow will turn offshore on Thursday as a thermal trough forms along the coast. Offshore flow will continue into the weekend then flip back onshore on Sunday.

Seas 5 to 7 ft tonight and Wednesday before relaxing slightly to 3 to 6 ft Thursday.

33/18

FIRE WEATHER
Benign fire weather conditions are expected through Thursday. However, a strong upper-level ridge will amplify over the region bringing not only continued dry weather but hot temperatures starting Friday and lasting through early next week.
A thermally induced surface trough appears to remain to our south around southern Oregon. This should keep discourage strong offshore winds which is a plus. However, hot, dry, and unstable conditions will be enough to maintain elevated fire weather conditions especially with fuels expected to dry out rapidly during this heat stretch.
