(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 ksew 201204 afdsew area forecast discussion national weather service seattle wa 404 am pst Wed feb 20 2019 Synopsis A cool upper level trough will remain over the area today keeping showers in the forecast. Dry northerly flow aloft developing tonight and continuing into Thursday. The next frontal system will arrive from the northwest on Friday. Another cool upper level trough will follow the front for the weekend into the early part of next week. Low snow levels will continue through the period. Short term today through Friday Satellite imagery shows the front that moved through the area Tuesday well to the south and east. Doppler radar shows convergence zone extending from about port angeles down to mount rainier with widely scattered showers elsewhere. Since noon yesterday paradise on mount rainier has received about 20 inches of snow. Skies remain mostly cloudy over most of the area with some clearing along the north coast. Temperatures at 3 am 11z were in the mid and upper 30s. Convergence zone will slowly sag south and dissipate this morning. Snow levels remain in the 500-1000 foot range this morning but the precipitation rates are not strong enough in the convergence zone to lower the snow levels any further. Outside of the convergence zone cool upper level trough moving into the area keeping a chance of showers in the forecast for the lowlands today. Showers more common in the mountains but the flow aloft is weakening rapidly which will result in not very impressive precipitation amounts in the mountains. Will let the advisory and warnings for the cascades expire at 6 am this morning. For the remainder of the day only a couple more inches of snow expected. Sounding like a broken record, highs today will be well below normal, mostly in the lower 40s. Upper level trough remaining over the area tonight with drier northerly flow aloft increasing after midnight. With the trough hanging around will have to keep a chance of showers in the forecast for the evening hours. Snow levels will be lowering as cooler air moves into the area so there is a chance that the showers could be rain and snow mixed or briefly in the form of snow. No significant accumulations expected. Lows tonight will be in the mid 20s to mid 30s. A little break in the action on Thursday with dry northerly flow aloft over the area. Cloud cover decreasing Wednesday night and with light surface gradients patchy morning freezing fog developing with the best chances over the southwest interior. Even with some sunshine Thursday afternoon highs will only be in the upper 30s to mid 40s. Temporary upper level ridge moving through the area Thursday night ahead of the next frontal system moving down the british columbia coast. Models in better agreement on the 00z run going more with the slower timing of previous ECMWF runs. The slower timing will keep the chance of precipitation confined to the north coast early Friday morning. Lows will be in the mid 20s to mid 30s. Slower timing of the front keeping most of the moisture out of the interior Friday morning. Snow levels will be low, 500 feet or less, so if the precipitation does arrive a little earlier it will be in the form of snow initially. As with the previous system increasing onshore flow ahead of the system will lift the snow levels up to around 1000 feet in the afternoon. Highs on Friday will be in the lower to mid 40s. Long term Saturday through Tuesday Extended models in good agreement with the front moving through the area Friday night into Saturday morning with another post frontal convergence zone possible. This feature has the potential to lower the snow levels back down to 500 feet or less. Cool upper level trough settling over the area for the weekend into Monday. With the trough in the area will have to keep at least a chance of showers in the forecast. Snow levels will remain low generally 1000 feet or less. Any showers that occur in the late night and early morning hours could result in some small snow accumulations especially on the higher hills. |
Model solutions very inconsistent on Tuesday with the ecmwf lifting a warm front up from the south into the area. The gfs keeps this feature well south of the area. With the lack of consistency in the models will go with chance pops on Tuesday. Highs will remain well below normal through the period with a chance for some warming on Tuesday. Felton Aviation Northwest flow aloft will become northerly today as an upper trough axis shifts east of the cascades. The air mass is moist and somewhat unstable this morning. A convergence zone across the southern part of puget sound will gradually dissipate later this morning as it moves into the cascades. Low level northerly flow will increase this afternoon. This combined with dry northerly flow aloft will gradually erode widespread ifr and low MVFR ceilings across the region this morning. Ceilings will lift toVFR this afternoon and scatter out this evening. Ksea... Shower activity and low MVFR ceilings associated with the remnants of the pscz will persist through mid morning then a trend toward improvement will take place from 18z onward.VFR ceilings at or above 5000 feet expected by around 22z... Then scattering out by late evening. Surface winds light n-nw becoming northerly 7 to 11 knots this afternoon then light NE tonight. 27 Marine Small craft advisory strength northwesterly winds over the coastal waters will gradually ease today and tonight in the wake of a front. Increasing fraser outflow will bring a period of small craft advisory strength northeasterly winds to the northern inland waters and eastern half of the strait of juan de fuca tonight and Thursday morning. There will also be 10-15 foot west to northwest swell over the coastal waters today and tonight which will subside on Thursday. A frontal system will drop down from the northwest on Friday with northeasterly offshore flow turning more southerly ahead of the front Thursday night. Northeasterly offshore flow will develop again next weekend as high pressure builds over the interior of british columbia.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
