Area Forecast Discussion National Weather Service Seattle WA 228 PM PST Fri Dec 13 2019

SYNOPSIS. Snow showers will gradually taper off in the Cascades through this evening. Scattered showers and perhaps an isolated thunderstorm in the lowlands will continue into this evening before tapering off. A shortwave ridge will bring calmer weather to the region this weekend with a more active weather pattern potentially making a return mid to late next week.

SHORT TERM /TONIGHT THROUGH MONDAY/. Scattered rain and snow showers will gradually taper off across Western Washington through Saturday morning as a shortwave ridge builds off shore and pushes across the region. A northwesterly flow regime will set up in its wake, yielding generally quiet weather across the region through the remainder of the weekend. The upper level pattern will gradually amplify through the end of the period as a ridge builds off of the northwest coast. A cold airmass will remain in place, with model ensembles showing low to mid 30 low temperatures in the low lands on Sunday and Monday mornings. Highs are generally progged to run around normal for mid December.

LONG TERM /TUESDAY THROUGH FRIDAY/.

Ensemble guidance is consistent in the aforementioned upper level shortwave ridge pushing across the Pacific Northwest as the first of a potential series of shortwave troughs ejects out of the Gulf of Alaska. This will bring a return of wet and active weather to western Washington by midweek. GEFS, EPS, and GEPS members show a healthy fetch of moisture ahead of second wave later next week into next weekend which would bring another round of rain and mountain snow to the region. Stay tuned to the latest forecast through the weekend into next week as details with these potential systems become clearer.

Pullin

AVIATION. Westerly flow aloft will become northwesterly tonight as weak upper ridging shifts in the coastal waters. A weakly unstable air mass this afternoon will stabilize overnight, but remain moist with light surface gradients. This will lead to the development of widespread MVFR ceilings and possible pockets of IFR overnight. These conditions will persist into Saturday morning with modest improvements expected Saturday afternoon.

KSEA . With a moist and increasingly stable air mass in place, VFR ceilings will deteriorate to MVFR this evening. Low MVFR is expected by around 06Z with the possibility of IFR ceilings for a period Saturday morning. There may be some marginal improvement in ceilings by Saturday afternoon, but available guidance does not lend a lot confidence in this occurring. Surface winds light southerly becoming W-SW less than 7 knots Saturday afternoon.

27

MARINE. Small craft advisories for hazardous seas continue into Saturday for the coastal waters and west entrance to the strait. Seas will gradually diminish over the weekend. Otherwise, no wind related concerns are anticipated over area waters. Winds will become increasingly offshore early next week as surface high pressure gets more established east of the Cascades.

27

HYDROLOGY.

There are no flooding concerns at this time as shower activity will remain scattered and light. Generally quiet conditions will prevail through the weekend and into early next week before the next storm systems affect the region by mid next week.

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