(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 ksew 221111 afdsew area forecast discussion national weather service seattle wa 310 am pst Fri feb 22 2019 Synopsis A frontal system will bring rain and mountain snow today. A cool upper trough will follow the front this weekend and into early next week. Low snow levels will continue through the period. Short term today through Monday Starting to see some weak echoes on radar over nearshore marine waters serving to herald the approach of the incoming system. Conditions and snow levels along the coast remain in the 1000-2000 ft range... So no worries for mixed precip there... Should all be rain. Models remain consistent that main thrust of precip still expected to hold off until afternoon when interior snow levels will also rise above 1000 ft and as such bulk of precip today will be in liquid form. Morning pops are a little bit on the aggressive side although in the case of the potential for mixed precip and its associated impacts... Likely better to err on the side of caution. Once precip band makes it to the cascades this afternoon... Snowfall amounts there continue to look like they will fall solidly within advisory criteria and as such inherited winter weather advisory will be left in place. Although the front exits the area tonight... An upper level trough over the area will keep showers in the forecast for much of the weekend. Showery conditions Saturday may see some flakes mix in as some locations will see snow levels dip a bit down to around 500 ft but the majority of lowland locations will see precip remain rain... Especially as snow levels climb back to about 1000 ft by late morning. Sunday will see activity taper some as most of the action travels south however the southern portion of the cwa... Say from olympia south... May still see some lingering showers. As one would expect... The diurnal pattern for snow levels will see them dip early Sunday am once again resulting in the potential for mixed precip however... Again... Snow levels do not fall too much below 500 ft and as such chances are better for mostly rain with a few flakes here and there. Most recent model runs have precip pushing back north a little more than the solutions of 24 hours ago while maintaining that snow levels throughout the day will remain near sea level for the morning and afternoon hours before rebounding slightly in the evening. Pops during this time frame still remain relatively low... Generally around 30 pct or less... However this would allow for any precip that does fall to fall as snow in the lowlands. While discrepancies remain in the finer details... The general trend continues to show a winding down of activity and little if any snowfall or accumulation expected. As such... Will treat as a minor irritant at best for now. All in all... Very little in the way of adjustments to inherited short term forecast as near term models remain fairly consistent with only a few minor hiccups in the details. Smr Long term Tuesday through Friday Models remain out of sync with one another for Tuesday... Keeping confidence in the long term pretty low. Current GFS runs show dry conditions Tuesday whereas the ecmwf is pretty antithetical to that. They appear to realign starting Wednesday morning with conditions being pretty wet over W wa for much of the day and into the bulk of Thursday as an upper level low moves eastward through the area. Models diverge again after that as the ECMWF keeps a troughy pattern over the pac NW while the gfs ushers in a pretty steep ridge from over the pacific. |
Fortunately... No matter which model is right regarding the upper level systems... Precip and what have you... The consensus is that snow levels will climb throughout the long term period... Getting up to the 3000-4000 ft range by Thursday Friday and as such any precip from Wednesday on will be liquid. Should this remain consistent in future runs... May finally be able to put the specter of this winter in the rear view mirror. Smr Aviation Westerly flow aloft with increasingly moist air mass ahead of an upper trough and associated cold front shifting southeastward into the area today. Areas of MVFR ceilings will develop as rain spreads across the region from the northwest this morning. The front will reach the north coast around 18z then rapidly sweep across the whole of western washington by late afternoon. Given the flow aloft, there is likely to be some rain shadowing over the central puget sound and the lowest ceilings may be restricted to around frontal passage and a possible brief convergence zone behind it. More widespread MVFR ceilings are possible after 06z tonight as a moist post-frontal air mass remains in place and surface gradients weaken. Ksea... Ceilings lowering this morning with MVFR in rain developing 18z-20z. The precipitation may very briefly begin as a rain snow mix. Precipitation should taper off rather quickly behind the front with ceilings lifting back toVFR after 02z or 03z. Periods of MVFR expected to redevelop later tonight after 06z-08z. Light southerly surface winds will become gusty just ahead of the front... Becoming 10 to 15 gusting to 20 to 25 knots late morning into early afternoon. Winds easing back to under 10 knots this evening. 27 Marine A frontal system will move through the area today with small craft advisory strength southerly winds most waters becoming westerly this afternoon and evening and then easing. A weak surface low near queen charlotte sound Saturday morning will move south to the oregon coast by Sunday morning. Northeasterly offshore flow will develop Saturday night and continue through Tuesday with high pressure over british columbia and lower pressure to the south of washington.
