Synopsis for the northern and central washington coastal and inland waters - Broad surface ridging will remain centered well offshore with low pressure inland and will result in onshore flow for much of this weekend into early next week. A frontal system looks to traverse the area waters on Tuesday. Additional systems may develop and move through the region late this week.

Area Forecast Discussion National Weather Service Seattle WA 228 AM PDT Mon May 20 2024

SYNOPSIS
A weak upper level ridge will produce warmer and drier conditions today. Another trough will drop south into Western Washington from British Columbia on Tuesday and Wednesday for a return to cooler and unsettled weather. A brief dry break is possible on Thursday, before cool and unsettled conditions return Friday and persist into the start of the weekend.

SHORT TERM /TODAY THROUGH WEDNESDAY/
Skies are mostly clear across much of Western Washington early this morning as weak upper ridging moves into the region. With some sunshine and weaker onshore flow today, high temperatures will approach seasonal levels...at least for interior areas. High level clouds will begin to increase by afternoon as the next in a series of upper level troughs and associated fronts approaches from the northwest. Rain will reach coastal areas after midnight tonight then spread into the interior on Tuesday morning. QPF forecasts remain fairly impressive for late May with roughly a half inch or more for much of the lowlands and 1 to 2 inches in the Cascades. The trailing upper trough will settle over the area on Wednesday for a continuation of showery, cool conditions with snow levels dropping to around 4000 feet or so.

LONG TERM /THURSDAY THROUGH SUNDAY/
The second half of the week looks to mimic much of what we've seen lately. Thursday may end up being a virtual carbon copy of Monday as weak ridging aloft briefly noses into the area before yet another trough digs southward into the area along the British Columbia coast on Friday with additional shower chances and continued below normal temperatures. Chance PoPs and below normal temperatures continue into weekend as the region remains under the influence of troughing aloft. Global ensembles are hinting at a possible shift in the pattern early next week with upper ridging rebounding over the Intermountain West and upper troughing taking up residence over the Gulf of Alaska. It's a bit far off to hang one's hat on, but it's something to keep an eye on if you're looking for more seasonable conditions. 27

AVIATION
N/NW flow aloft over western WA today with a trough over the Intermountain West. The low level air mass remains moist with onshore flow and there are patchy low clouds (MVFR conditions) over the coast and south sound. VFR conditions will prevail in the afternoon. The flow turns westerly late Tuesday night with rain spreading inland by 12-15z Tue as the next frontal system moves in. 33

KSEA...Patchy low clouds possible early this morning (20 percent chance of MVFR conditions). Otherwise, dry today with VFR this afternoon. Winds S/SW around 5 kt. Moisture increases overnight with rain spreading inland by 12z Tue. 33

MARINE
High pressure over the NE Pacific will maintain onshore flow across western WA this week. Highest wind and waves will be through the Strait of Juan de Fuca and outer Coastal Waters - Small Craft Advisories are in effect. A frontal system will cross the waters on Tuesday with another system on Friday. 33
