Area Forecast Discussion National Weather Service Seattle WA 237 PM PST Wed Dec 11 2019
SYNOPSIS. An active weather pattern across the Pacific NW the next several days will continue. A trough of low pressure will bring rain and mountain snow the next several days with significant snow accumulation in the highest elevations. There will be drier and cool weather by Saturday and Sunday, and early next week, before a more active pattern develops again in the middle of next week.
SHORT TERM /TONIGHT THROUGH SATURDAY/. Radar shows showers continuing to overspread the forecast area this afternoon and this trend is set to continue. Snow levels have started out lower than earlier expectations, with snow falling in Snoqualmie Pass already. This is due to the local effects of easterly flow bringing lower snow levels in the pass. This has been the biggest change to the snow forecast, with heavier accumulations there. As a result, the winter storm warning was amended to reflect impacts down to 3000 ft of elevation. Snow levels will remain in the 3000-3500 foot range for most of the overnight, and will increase on Thursday morning as westerly flow pushes in. Thursday will bring showery conditions, with a chance of heavy mountain snow showers by Thursday evening.
Winds will increase out of the south tonight and into early Thursday. They will not be overly significant or impactful, but gusts up to 35 MPH are possible, especially near the water.
The concern on Thursday will be an increase in intensity of the showers by later afternoon. 6 hourly model QPF in the .25-.50 inch range suggests heavy showers in the mountains that will be capable of local dynamic cooling to cause snow levels to fall and produce brief periods of heavy snow. This will bring additional travel concerns, especially for Snoqualmie Pass where the snow levels are likely to rise Thursday morning, but fall again in the heavier snow showers Thursday afternoon.
Additionally, SPC guidance indicates chances of coastal thunderstorms the next few days, and this seemed reasonable, and so an isolated mention is present in the coastal areas.
Friday will bring a decrease in precip and a weak ridge will attempt to build in aloft. So temperatures will dip to near or below normal this weekend with somewhat drier weather although showers will be present in some form across the area through the weekend, just not overly widespread.
LONG TERM /SUNDAY THROUGH WEDNESDAY/. Ridging will actually start off the extended period and it looks to hold across the area into the start of next week. The breakdown of this ridging is in question and so the details remain in lower confidence levels at this time. The overall trend will be however for temperatures near normal. After this system today through Friday, there do not appear to be any significant weather impacts on the horizon.
AVIATION. A vigorous frontal system will move through Western Washington this evening with strong southwest flow aloft. Tonight and Thursday will have periods of rain and typical Western Washington rainy day cigs and reduced vsby. The mountains and foothills will remain obscured.
KSEA . Periods of rain with breezy southerly winds tonight and Thursday. Cigs will average 1500-2500ft and vsby will drop at times to 3-5miles in rain.
MARINE. A strong frontal system will move through the area this evening. A trough will move ashore on Thursday. Gale warnings are up for the coastal waters, east entrance to the Strait of Juan de Fuca, and the northern waters. For the coastal waters, swell Thursday and Friday should be 15-18 feet with the main period around 16 seconds.
HYDROLOGY. A wet storm system will impact the region this afternoon through Friday. Given precipitation amounts and snow levels in the 3500-5000 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.
