Area Forecast Discussion National Weather Service Seattle WA 850 PM PST Mon Jan 27 2020

UPDATE. A strong upper level area of low pressure can be seen swirling across the offshore waters of western Washington this evening. An organized sfc frontal system is associated with it, the warm frontal portion of which is moving into western Washington this evening. Strong WAA in the 925-700 mb coupled with frontogenetic forcing has allowed for widespread rain to move into the area. Radar trends have suggested that some of this activity could be moderate to locally heavy at times. Overall impacts should be minimal, tho locally heavier areas of rain may produce some ponding on roadways. Snow is likely to continue across the Cascades overnight given widespread precip giving way to convective showers, with the Winter Weather Advisory remaining in effect for much of Tuesday morning until the front clears the area. This will likely create treacherous travel across the Passes. Avalanche concerns also remain: see the latest from the Northwest Avalanche Center at nwac.us.

Into the overnight hours, the cold front will follow the warm front, creating more a convective shower environment in the wake of the stratiform rain. Model guidance indicates mid level temps falling to near -30C as the upper level trough begins to approach western Washington. This will create an unstable environment, with mid level lapse rates steep enough to support the develop of a few thunderstorms. This threat will continue through Tuesday morning until the front moves east of the area. The main threats within any thunderstorm will be gusty winds, heavy rainfall, small hail, and lightning.

A brief lull will ensue across the area Wednesday evening and night as a brief shortwave ridge passes above. The next frontal system is on tap for Wednesday. Previous discussion follows below with an updated marine and aviation section:

PREV DISCUSSION. /issued 237 PM PST Mon Jan 27 2020/

SYNOPSIS. A front will move through Western Washington this evening. Additional precipitation will fall through Tuesday as the associated low pressure system weakens and moves ashore. Additional frontal systems will affect the region Wednesday through Saturday.

SHORT TERM /TONIGHT THROUGH THURSDAY/. A front will move through the area this evening. A few periods of fairly organized shower activity will follow the front tonight through Tuesday. The passes ought to pick up about a foot of snow from this system but travel probably wont be impacted a great deal since it hasn't been cold --although it will probably get slushy at Snoqualmie Pass tonight. Tuesday night will see a break in the weather, and then a couple of warmer fronts ought to reach the area Wednesday and Thursday. The low pressure centers associated with these two fronts are nowhere near Western Washington and a little breezy weather is about all we will see with these fronts.

LONG TERM /FRIDAY THROUGH MONDAY/. The frontal system slated for Friday and Saturday will be wet and mild, although the heavy rain in the 12z GFS ends up over Vancouver Island and southwest British Columbia Friday night and Saturday. The ECMWF has more rain for Western Washington with less of a tendency to lift the precip north of here--although for Friday afternoon and evening only the Olympics and North Cascades have the heavy precip. Behind that frontal system cooler drier air will arrive for Sunday and Monday. 19

AVIATION. Rain will continue across the TAF sites into the overnight hours, eventually becoming more showery around midnight or so. Ceilings as of 730 PM are mostly VFR and MVFR, and expect the general trend of MVFR to dominate most of this TAF cycle. Will have the potential for a few thunderstorms/lighting strikes across the area, mainly after midnight and through Tuesday morning. Coverage is not high enough, nor is confidence high enough, to warrant mention in the TAFs for now, but the potential will develop across most of the area. In addition to rain, thunder potential, and lowering cigs, LLWS is expected to increase overnight. Will likely add this to at least the TAF sites around Puget Sound during the 06z update-this will include KSEA. Winds will be south 8-12kts with a few gusts 20-25kts near the coast (KHQM).

KSEA . Rain will become more showery after midnight, with the potential for isolated thunder in the vicinity thru Tuesday morning. VFR cigs this evening likely to give way to dominant MVFR deck for the remainder of the cycle. LLWS is also expected through about 12z Tuesday and will be added to the 06z update. Winds S thru the period 8-12kts.

Kovacik

MARINE. Based on observations over the past few hours, winds have noticeably increased down the Strait of Juan de Fuca from the east. Have upgraded the small craft advisory to a Gale Warning through 10PM. Model guidance then indicates that gradients should weaken through the night. A frontal system responsible for these winds will continue to move through the waters tonight, keeping small craft winds at least into early Tuesday morning. A continued series of weather systems are likely to keep marine headlines in for wind through much of the week, with perhaps some brief breaks at times.

Kovacik

HYDROLOGY. With the exception of the Skokomish river, flooding is not expected through Thursday. The Skokomish will remain above flood stage through the week. A possible atmospheric river scenario could set up beginning later Thursday and continue into Saturday. This event has the potential to create another round of flooding on area rivers.

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