Area Forecast Discussion National Weather Service Seattle WA 333 PM PDT Thu May 16 2024

SYNOPSIS
Upper-level troughing through much of the upcoming weekend. With it, cooler and showery conditions are in store.
Brief ridging is expected to start the upcoming week before troughing rebounds through the middle of next week.

SHORT TERM /TONIGHT THROUGH SUNDAY/
As mentioned, upper- troughing is currently positioned over the region. At the surface, a frontal boundary is pushing towards western Washington out of BC. With it, increased onshore flow and spotty precipitation is being observed across the area. Light rain showers are in the forecast this evening along with convergence activity. Most of the precipitation will fall in higher elevations with aid of orographic enhancement. High-res guidance has the PSCZ focused mainly over Snohomish County before drifting southwards over King County overnight tonight. With troughing overhead, cooler temps aloft are expected with snow levels around 3,000-3,500 ft.
Overnight lows are to fall into the low to mid 40s.

Lingering showers are possible into Friday as we'll be on the backside of the upper-trough. Nevertheless, drier conditions are expected but cooler temps are to remain with highs slightly below average. Then, the next upper-low is on track to enter on Saturday with another round of showers. However, a drying will try to set up on later on Sunday as transient ridging moves overhead by the nighttime hours. Weekend highs are to top out in the mid 50s to lower 60s with overnight lows in the 40s.


LONG TERM /MONDAY THROUGH THURSDAY/
Ridging to remain over the region on Monday but it won't be long lasting. Active weather looks to resume around the Tuesday-Wednesday timeframe as another upper-low out of BC dives south into the region. Temperatures are to be around average for Monday but, cooler temps along with wet weather looks to pick back up as the week continues.

AVIATION
West to northwesterly flow will persist aloft as an upper level trough from British Columbia continues to dig and slide across the Pacific Northwest. Surface flow generally remains southerly this afternoon, with gusty winds across the area ahead of an approaching frontal system. This system is also responsible for light shower activity on radar this afternoon. Overall, expect showers to remain light and rather spotty, except for a convergence zone that looks to develop and persist across portions of the central Sound tonight. Showers and the PSCZ look to dissipate overnight. Cigs across the area are generally a mixed bag of MVFR and VFR, with a few spots of IFR as well. Can expect a mix of high end MVFR, low end VFR cigs to persist into this evening (with a few spots of IFR cigs in showers), with gradual improvement towards VFR expected. Latest NBM probabilistic guidance indicates a 30-50 percent chance of cigs lowering back down to MVFR again by Friday morning, likely between 12-15Z.

KSEA...Conditions MVFR with gusty southerly winds to 25-30 kt ahead of an approaching frontal system. Expect PSCZ activity to remain north of the terminal this evening and an improvement towards low- end VFR conditions by tonight. Guidance showing a 30 percent chance of cigs lowering back down to MVFR between 12-15Z. Winds will remain breezy through tonight, but look to gradually ease through the Friday morning hours. 14

MARINE
An incoming frontal system will keep conditions breezy across the area waters into Friday. Small craft advisories will be in effect for all area waters as a result. Seas across the coastal waters will build towards 10 ft on Friday, likely resulting in an extension of small craft headlines for the coastal waters zones.
High pressure offshore looks to remain persistent into next week.
With lower pressure situated inland, expect onshore flow to persist through the forecast period. Another frontal system looks to move across the area waters early next week and may result in another round of headlines.

Seas currently hovering at 4-6 ft over the coastal waters this afternoon. Expect seas to build towards 9-12 ft on Friday before gradually subsiding back to 5-7 ft over the weekend and into early next week. 14
