Area Forecast Discussion National Weather Service Seattle WA 416 AM PST Sun Dec 10 2023
SYNOPSIS
A frontal system will sag south into Oregon today.
Upper level trough moving through tonight keeping a chance of showers in the forecast. Weak upper level ridge building Monday will strengthen Tuesday then shift east Wednesday. Next system arriving late Wednesday could hang up over the area into Thursday morning. Weak upper level ridge building to the east Friday with a warm front brushing the area into Saturday.
SHORT TERM /TODAY THROUGH TUESDAY/
Satellite imagery shows front hung up over Southwest Washington early this morning.
Doppler radar has light rain from about Seattle north with heavier rain south of Seattle. Temperatures have been warming up overnight and are now in the 40s to lower 50s except in Whatcom county where northerly winds are keeping temperatures in the 30s.
The front will slowly sag south today eventually getting into Northern Oregon. No cold air cumulus on the satellite imagery so shower activity behind the front will be limited. Low levels of the air mass extremely moist so even with the steady rain ending do not expect much if any clearing. Highs will only be a couple of degrees warmer than the current temperatures, upper 40s to mid 50s. While snow levels over the South Cascades have risen to near 5500 feet the colder air has been slow to scour out of the Central and Northern Cascades with snow levels still near 3500 feet. Not much precipitation left for the Northern Cascades so will let the Winter Weather Advisory expire. Will also let it expire over the South Cascades with snow levels at least 5500 feet. In the Central Cascades a wintery mix continuing this morning. Snoqualmie pass has been reporting rain for the last few hours with temperatures below freezing. It has been snowing at Stevens Pass all night.
Another 1 to 5 inches of snow possible this morning along with the potential for freezing rain so will keep the winter storm warning going until 10 am for the Central Cascades.
Upper level trough moving through Western Washington overnight.
Not a whole lot with this feature but enough to keep a chance of showers in the forecast. Snow levels will lower back down to the higher passes by Monday morning but little snow is expected. Lows tonight in the upper 30s to mid 40s.
Weak upper level ridge building over Western Washington Monday bringing about an end to the precipitation chances by late in the day. Plenty of low level moisture combined with not much subsidence with the weak ridge will keep skies mostly cloudy.
Highs near 50.
Ridge continuing to build Monday night helping skies clear a little. With the lower levels of the air mass so moist any clearing will result in fog forming so after with light surface gradients as well. Fog could be dense by Tuesday morning especially in the Southwest Interior. Lows Monday night in the mid to upper 30s.
Upper level ridge remaining over the area Tuesday. Light surface gradients continuing through the day. This could make the fog hard to clear out. For now will go with an afternoon breakout with a little increase in offshore flow putting highs in the mid to upper 40s. It is certainly possible the fog will hang around longer resulting in a cooler day.
LONG TERM /WEDNESDAY THROUGH SATURDAY/
Extended models and ensembles in good agreement with the next front arriving Wednesday night bringing another round of rain to the area. This system is nowhere near as moist as what we have seen recently so rainfall amounts will not be excessive. Large upper level trough digging south in the Eastern Pacific between 140 and 150W could stall the front over Western Washington Thursday. Upper level ridge building later Thursday into Friday in response to the deepening trough further to the west. It will be a race between how fast the ridge can build versus how far east a warm front moving out of the low gets towards Western Washington. The GFS ensembles favor the ridge building enough to shove the warm front north of the area. The ECMWF ensembles are split with about half of the solutions indicating rain Friday into Saturday. Model blend gives slight chance pops leaning towards the GFS solution. No reason to change this idea at this point but with the differing solutions confidence not very high for the Friday and Saturday forecast.
AVIATION
A front will move across the area today, bringing areas of rain to western Washington. Post frontal showers will taper late in the day, though hi-res guidance does hint at a convergence zone developing along the north-central Sound (mainly near and north of KPAE). Flow aloft is westerly. Overall conditions this morning are a bit of a mixed bag, but trending more widespread MVFR to IFR. Low MVFR to IFR ceilings look to continue through much of the day today. Winds will continue to ease this morning and will generally be southerly, persisting at 7-12 kt through this afternoon, before easing to 3-6 kt tonight.
KSEA...Conditions generally MVFR to IFR this morning. Expect these lower ceilings to continue throughout the day. Low level wind shear potential continues through this morning with southerly winds at 2000 feet around 40 knots veering southwesterly. Surface winds are SE at 7-12 kt, decreasing to 3-6 kt this afternoon.
MARINE
A cold front will move across the area waters today. Winds have started to ease across the region, though Small Craft Advisories remain in effect for the Northern Inland Waters, East Entrance of the Strait of Juan de Fuca, and Admiralty Inlet through early this morning. Small Craft Advisories also remain in effect for the Coastal Waters, West Entrance of the Strait, and Grays Harbor Bar through this afternoon and evening for seas above 10 feet.
Surface high pressure will then build across the coastal waters on Monday, bringing calmer conditions and offshore flow to the region. The high pressure system will shift inland Tuesday, allowing for a weak frontal system to move into the area Wednesday into Thursday.
Seas 12-15 ft will gradually subside to 10 ft tonight and 5 to 7 ft through the day on Monday. Seas will then increase towards 10 ft again near midweek as another swell train makes it into the area. 14
HYDROLOGY
The Skokomish river is on the rise this morning and with the air mass over the Olympics warming up a flood warning for the river will be issued with this forecast package. Heavy rain continues over the higher elevations in the southern portion of the state. Paradise on Mount Rainier has reported 0.79 inches in the last three hours with a temperature of 32 degrees and no new snow accumulation. Will also go ahead and issue a flood watch for Lewis, Thurston and Grays Harbor county for the possibility of portions of the Chehalis and Newaukum rivers reaching flood stage this afternoon into Monday morning.
Still getting significant precipitation in the Central Washington Cascades but with the slower warm up keep the precipitation in the form of snow this morning will keep the counties with rivers flowing out of the Central Cascades out of the flood watch.
Hydrologically significant precipitation will be done with by later today over the entire area. The front later in the week will not cause much in the way of rises on the rivers.
Continued rainfall this morning along with recent precipitation earlier in the week will increase soil instability, leading to an increased threat of landslides. The threat of landslides, especially in the southern portion of the area, will continue into Monday. Felton
