Area Forecast Discussion National Weather Service Seattle WA 835 AM PDT Sat Jul 11 2020

SYNOPSIS. Dry weather will persist into this afternoon before a weak cold front brings scattered showers tonight and into Sunday. Generally dry and seasonable weather expected for early next week although some weak systems may allow for scattered showers at times.

SHORT TERM /TODAY THROUGH MONDAY/. Clouds will increase today as a trough and weak cold front move inland. Showers associated with this front are seen on the coastal radar with showers reaching the coast this afternoon. Expect showers in the interior mainly late this afternoon or early evening. No changes from the previous forecast. 33

Previous discussion . Will see clouds gradually increase throughout the day today as the aforementioned front draws closer but precip looks to generally hold off until late this afternoon and through tonight. Deterministic models continue to show this feature weaken as it moves eastward and most ensemble members remain unenthusiastic with regards to precip chances and amounts . save for the higher elevations where PoPs look to get into the likely category. Some showers will linger into Sunday as the associated upper level low up in Canada is not in much of a hurry to make any eastward progress . but dry conditions are expected to resume by Sunday evening. This dry weather will continue through Monday as an upper level ridge from the Pacific moves over the Pac NW.

Temps today and Sunday will remain fairly mild with highs along the coast in the lower to mid 60s while locations in the interior will sit generally in the lower 70s. As the ridge moves in for Monday . temps look to receive a little bump . in the lower to mid 70s . while coastal highs are expected to generally remain in the lower to mid 60s.

LONG TERM /TUESDAY THROUGH FRIDAY/. Previous discussion . Ridging remains in place at least into mid-week although deterministic models flatten out the ridge by Thursday. This does not spell an immediate end to the dry conditions however as neither deterministic model shows any organized system or precip dipping down south enough to impact the CWA Ensembles. however . paint a different picture. While seemingly a majority of members are also dry during this period a sufficient amount of members are wet and wet enough . some proving to be quite significant outliers . that this ends up boosting the mean average As such. there is an increase in PoPs for the second half of the week though really no confidence in such numbers given the absence of any real driving weather system.

Temps for the first part of the long term continue the upward climb started on Monday with interior high temps getting into the mid to upper 70s both days As the ridge flattens. temps moderate slightly down into the mid 70s. Coastal temps remain fairly static during this period . generally in the mid 60s. 18

AVIATION. Southwesterly flow aloft becoming westerly tonight behind front. Light flow in the lower levels becoming onshore and increasing behind the front. Increasing mid and high clouds and then rain developing on the coast this afternoon--spreading into the interior and breaking up in the early evening. Cigs will drop on the coast as the rain arrives this afternoon and cigs will drop later this evening in the interior as the areas of light rain or showers combine with increasing onshore flow to pack the moisture in. Convergence zone developing Sunday morning.

KSEA . Increasing mid and high clouds then cigs drop this evening as the front and light rain arrive.

MARINE. A weak front will move through the coastal waters this afternoon and the inland waters tonight. Onshore flow will increase behind the front. Varying degrees of onshore flow Sunday through Wednesday with high pressure over the coastal waters and lower pressure inland. Small craft advisory westerlies expected each evening in the Central and East Entrance of the Strait of Juan de Fuca.

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 . None. PZ . Small Craft Advisory from 11 PM this evening to 5 AM PDT Sunday for Central U.S. Waters Strait Of Juan De Fuca-East Entrance U.S. Waters Strait Of Juan De Fuca.

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