Area Forecast Discussion National Weather Service Seattle WA 835 PM PST Wed Dec 11 2019

UPDATE. Not too many changes were needed to the forecast this evening. Only tweaked POPs based on recent radar trends.

A frontal system will continue to make forward progress across the area overnight tonight. Steady rainfall continues eastwards across the area along and ahead of the cold front. This swath of precip will be supported by the left exit region of a strong jet streak aloft and will continue to provide for moderate rainfall in the lowlands and some moderate to heavy snowfall across the mountains. Current headlines appear to be in good shape for this event so have left everything currently in place as is.

In the wake of the cold front, precipitation will become more scattered/spotty. This being said, a slight chance of thunderstorms still appears possible across the coastal waters and slightly inland across the Washington Coast early Thursday morning and thru much of the day. Convection should be low topped and capable of mainly producing a few lightning strikes. This forecast matches up with well with SPC's Day 2 outlook.

The previous discussion has been included below as well as an update to the marine and aviation sections.

PREV DISCUSSION. /issued 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. Widespread rainfall (moderate to locally heavy at times) will continue to push west to east over the next several hours ahead of a cold front. The more moderate areas of rainfall may reduce vsbys for brief periods of time but overall should largely remain in the VFR range. Ceilings are a mixed bag, mainly VFR and MVFR with a few reports of IFR. Think ceilings will drop to mostly MVFR in the wake of the cold front. Rain should also become more spotty/scattered behind the front. Another front will bring the next round of widespread rain later in the day Thursday. Winds will be mostly southerly between 10-15kts with periodic gusts to 20-25kts thru Thursday.

KSEA . Widespread rain through midnight, becoming more scattered into Thursday morning. Some brief vsby reductions possible in the widespread rain. Ceilings are expected to drop from VFR tonight to MVFR overnight, with perhaps recovery back to VFR by Thursday afternoon. Winds south 10-15kts with gusts 18-22kts at times.

Kovacik

MARINE . No significant changes were made to the marine package this evening. Winds have struggled to reach gale criteria near the coast and across the northern interior waters. They are close enough to warrant leaving current headlines in place until 9PM. Thereafter a small craft advisory will remain in effect through Thursday afternoon. Previous discussion follows:

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.

Kovacik

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.

SEW WATCHES/WARNINGS/ADVISORIES. WA . Winter Storm Warning until 10 AM PST Friday for Cascades of Pierce and Lewis Counties-Cascades of Snohomish and King Counties-Cascades of Whatcom and Skagit Counties.
