Area Forecast Discussion National Weather Service Seattle WA 303 PM PST Tue Dec 10 2019

SYNOPSIS. A weak weather system is moving across the region today bringing light rain and mountain snow showers. A brief break is expected Wednesday morning before the next, much wetter system moves into the area late Wednesday into early Friday. This system will bring heavy snow to the Cascades, particularly above 3500 to 4000 feet. Active weather will continue into next week.

SHORT TERM /TONIGHT THROUGH FRIDAY MORNING/. Light precipitation associated with a dissipating front continues to push east across western Washington this afternoon. Amounts have been relatively light, generally between a tenth and a third of an inch. While many areas will see an end to precipitation overnight, a few showers will continue, mainly in the coastal hills and mountain foothills.

Attention then turns to the next system that will impact the region Wednesday into early Friday. This system will bring much more precipitation to the region, along with breezy conditions. The headlines are as follows:

* Lowland Rainfall: Most lowland areas will see 0.50-1.25 inches of rainfall, with higher amounts of 1.5-2.00 inches along the coast.

* Mountain Precipitation: The mountains will generally see 1.5-2.5 inches of liquid equivalent precipitation, with locally higher amounts around 3.0-3.5 inches.

* Snow levels: Snow levels will generally begin between 4000-5000 feet, then lower to 2500-3500 feet late Thursday night into Friday morning. This means that Stevens Pass will likely experience significantly more snowfall than Snoqualmie Pass. * Snow Amounts: Accumulations generally 3-6 inches below 3500 feet (again, mainly early Friday), 1-2 feet between 3500-4500 feet, and 2-4 feet above 4500 feet. (A Winter Storm Watch was issued for the Cascades)

* Gusty Winds: Breezy southerly winds are expected with this system with gusts generally 20-30 MPH. Stronger winds with gusts 35-45 MPH will be possible across and near the coastal waters, through the Strait of Juan de Fuca, and in the north interior (waters near and north of Whidbey Island).

The heaviest and most widespread precipitation is likely to occur Wednesday evening/night, with precipitation becoming more showering in nature Thursday. In fact, there will exist a slight chance of thunderstorms along the coast and southwest WA Thursday afternoon and potentially again Friday as somewhat cooler air moves in aloft. -Wolcott-

LONG TERM /FRIDAY AFTERNOON THROUGH TUESDAY/. As we move into Friday afternoon through Saturday, precipitation chances will begin to diminish. That said, the pattern is messy and the door will be open for a weak system to brush the area over the weekend, so I wouldn't bet on a completely dry forecast.

Looking out further, there is good ensemble agreement in the continuation of an active pattern with the development of a mean trough just off the PNW coast. This will not only keep the door open for more energy to move through the area, but also sets up a more favorable pattern for wetter and warmer than average mid- December conditions. This matches well with the latest CPC 6-10 day and 8-14 day guidance. -Wolcott-

AVIATION. A front moved ashore this afternoon and will be east of the Cascades later this evening. The air is moist and stable with southwest flow aloft. Areas of low stratus are likely through tonight. The low clouds should break up for awhile ahead of the next front on Wednesday--and then conditions will drop again as rain moves ashore with the front Wednesday afternoon and evening.

KSEA . Cigs 1500-2500 feet tonight, and then there ought to be some improvement in conditions Wednesday morning--but then rain will develop Wed afternoon with cigs and vsby dropping into Wed evening with the next stronger front.

MARINE. A front over Western Washington this afternoon will move inland this evening. A stronger frontal system crosses the area Wednesday afternoon and evening and a trough will move through the area on Thursday. A gale warning is up for the coastal waters and the east entrance to the Strait of Juan de Fuca and northern inland waters have a good chance for gales Wednesday afternoon or evening as well. A trough will move through the area Thursday--tightening up the gradient a bit. On Friday onshore flow will ease. A weather system over the weekend should go in well south of the area.

HYDROLOGY. A wet storm system will impact the region Wednesday afternoon through Friday. Given precipitation amounts and snow levels in the 4000-5000 foot range - most rivers are not expected to approach flood stage. There is some concern that the Skokomish River in Mason County could approach flood stage. We will continue to monitor this situation. -Wolcott/Bower-
