Area Forecast Discussion National Weather Service Seattle WA 414 AM PDT Tue Jul 14 2020

SYNOPSIS. High pressure will allow for drier, warmer conditions across the area through mid-week with Wednesday likely being the warmest day of the week. A weak frontal system will brush the area later Thursday and Friday with a few showers. Upper ridging will rebuild for drier and warmer conditions from the weekend into early next week.

SHORT TERM /TODAY THROUGH THURSDAY/. Upper ridging continues to build into the region this morning with clear skies across the area except for some patchy stratus near the coast. The low level flow will only be weakly onshore today and with rising heights temperatures most places will add another 2 to 4 degrees over yesterdays highs. Stratus will be more prevalent along the coast by late tonight and will likely be slower to clear there on Wednesday. Wednesday will be similar to today across most of the interior with plenty of sun and another 2 to 4 degrees of warming. By later Wednesday afternoon, onshore flow will strengthen and this will bring the stratus into the Puget Sound lowlands Thursday morning. Upper ridging will flatten on Thursday and a few showers could reach the north coast and north interior by late in the day. Temperatures will cool by several degrees, but to only slightly below normal this time around.

LONG TERM /FRIDAY THROUGH MONDAY/. Weak upper troughing lingers into Friday, but heights will be rebounding by late in the day as an upper ridge builds strongly into the offshore waters. In contrast to much of June and the first part of July, model ensembles largely favor mean upper ridging just offshore with weak troughing over the northern plains. And this points to a more sustained period of warmer and dry conditions for Western Washington as we enter next week. 27

AVIATION. Northwesterly flow aloft with upper level ridge well offshore. In the lower levels onshore flow continuing into Wednesday.

Clear skies over most of the area today. Areas of low clouds along the coast with ceilings below 1000 feet until 16z. Patchy fog in the Lower Chehalis Valley and Southwest Interior until 15z.

KSEA . Clear skies with northeast winds 4 to 8 knots becoming northwesterly midday. Felton

MARINE. Varying degrees of onshore flow into the weekend with high pressure over the coastal waters and lower pressure inland. Expect diurnally driven small craft advisory west winds through the central and east entrance to the Strait of Juan de Fuca each evening. Small craft advisory northwesterly winds over the southern portion of the coastal waters tonight. Felton

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

CLIMATE. The high in Seattle on Monday was 76 degrees matching the normal high for the day. The forecast high of 77 degrees today will break the streak of 17 days in a row in Seattle with a high temperature at or below normal. Last day with a high above normal in Seattle, June 26 with 82 degrees. Felton

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
