Area Forecast Discussion National Weather Service Seattle WA 827 PM PDT Tue Jul 14 2020

UPDATE. Mostly clear skies across Western Washington this evening with a few high clouds. Clear conditions for most tonight with stratus along the coast and through the Strait of Juan de Fuca. Dry and warm into the 70s to low 80s on Wednesday as the upper ridge moves over the area.

SYNOPSIS. Dry and warm weather will continue through mid-week with the warmest afternoon expected on Wednesday. A weak frontal system will pass across the area on Thursday bringing showers to the area through Friday. Then, the development of a blocking pattern over the Pacific this weekend will allow for the return to dry and warm conditions across the area through at least the middle of next week.

SHORT TERM /TONIGHT THROUGH FRIDAY/. A synoptic scale analysis of the weather pattern this afternoon shows continued NW flow aloft across the Pacific Northwest as a large anticyclone remains centered over the North Pacific and two notable areas of low pressure reside across SE Alaska and Northern Saskatchewan/Manitoba, respectively. At the surface, high pressure reflection the upper level anticyclone remains anchored across the North Pacific, with ridge influence extending eastward into Western Washington, with a thermally induced area of low pressure over eastern Washington.

As was the case yesterday, the synoptic analysis provided above sums up the clear skies and warm temps that we are experiencing today. Pacific high pressure has nosed a touch more into the area compared to this time yesterday, providing a bit more subsidence aloft. This has yielded generally sunny skies with temperatures running a few degrees warmer than Monday afternoon. IR satellite (and a glimpse out the window) suggests a few high level clouds spilling across the region overtop of the ridge, associated with a few active shortwaves across both the Pacific and BC. Mostly clear skies will continue through the afternoon and evening.

Onshore flow will continue overnight tonight as sfc high pressure remains centered over the Pacific and lower pressure resides inland. This will allow marine stratus to redevelop along the Coast and also push down the Strait of Juan de Fuca and into portions of Northern Puget Sound. Some of this stratus may be able to push a touch inland in the vicinity of these bodies of water. Stratus will then retreat back to the immediate Coast by late morning and thin along the Strait. The upper level ridge will also begin to dampen and lose influence across the Pacific Northwest on Wednesday as a shortwave trough barrels through the stronger belt of westerly flow just south of the Gulf of Alaska, enroute towards the local area. This system will be carrying a sfc front with it, which is set to pass through the local area on Thursday. Before its arrival, the warmest temps of the week are expected on Wednesday, with highs into the low 80s across most lowlands (near 70 by water) and another mostly sunny day.

As just mentioned, a shortwave trough will move across the local area on Thursday, carrying with it a sfc frontal system. There does not appear to be much deep layer moisture associated with the front as it moves into the area, but showers will be likely through the day, especially across the northern half of the area. The passage of the shortwave will then yield a lingering trough and keep for slightly unsettled conditions on Friday. Showers will be possible through the day, especially across the Cascades with conditions gradually drying out through the evening and overnight period.

LONG TERM /SATURDAY THROUGH TUESDAY/. The synoptic pattern to begin the long term will feature some residual troughing across the Pacific Northwest, with a ridge of high pressure beginning to strengthen and build north across North Pacific. This will help push the storm track a bit further north and also aid in the beginning stages of the development of a Rex Block as low pressure deepens to the anticylone's south. With high pressure continuing to dominate in the lower levels, it is shaping up to be a nice weekend across western Washington, with high temps rebounding back towards or into the low 80 in the lowlands by Sunday. The Rex Block will remain anchored across the Pacific into early next week, essentially locking this pattern into place, with a slight retrogression westward noted towards mid-week. This pattern will keep us dry and warm. Will need to keep an eye on fire weather conditions next week given that almost week's worth of dry and warm weather will allow fuels the opportunity to quickly dry out.

AVIATION. Northwesterly flow aloft through Wednesday with an upper ridge over the area. VFR cigs through Wednesday for most with IFR along the coast tonight into Wednesday morning. North to northeast winds through Wednesday 4 to 8 knots.

KSEA . VFR cigs. North winds this evening with northeast winds tonight. North-northwest winds 4 to 8 knots for Wednesday. JD

MARINE. Onshore flow at times through this week with increasing onshore flow most evenings. Small Craft Advisory tonight for most of the coastal waters for northwesterly winds. SCA winds for the central and eastern portions of the Strait of Juan de Fuca tonight with a westerly push. Increasing onshore flow Wednesday night and Thursday night for stronger winds through the Strait of Juan de Fuca. Seas 3 to 6 ft through this week with a system moving through Thursday into Friday. JD

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

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