(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 ksew 231009 afdsew area forecast discussion national weather service seattle wa 309 am pdt Tue jul 23 2019 Synopsis An upper trough will bring clouds and a few showers Tuesday and Tuesday night. Weak high pressure aloft will bring dry and warmer weather Wednesday and Thursday. A weak frontal system will bring another chance of showers later Friday. Dry onshore flow will prevail next weekend. Short term today through Thursday An upper trough is approaching the region today and will move through the area tonight. Onshore flow continues to push stratus inland from the coast this morning. Most of the lowlands with the exception of parts of the north interior should be covered by later this morning then low clouds will lift and burn off. The clouds and stronger onshore flow will cool highs to near or slightly below normal. Southerly flow aloft and some instability over the cascades will produce a slight chance of thunderstorms this afternoon and evening. As the upper trough moves through the region, there's a chance of a few showers over the lowlands from about seattle northward late this afternoon through early Wednesday morning. A few showers will probably linger over the cascades on Wednesday. Otherwise, it looks mainly dry as weak high pressure aloft moves over the area. Morning clouds should burn off for a partly to mostly sunny afternoon. Highs will warm a few degrees. The drying and modest warming trend should continue into Thursday with a flat upper ridge over the area and high temperatures a few degrees above normal. Long term Friday through Monday Upper ridging weakens on Friday with another trough clipping the area Friday night. It might be strong enough to produce a few showers over the northern half of the forecast area. Clouds and a few showers could linger into the first part of Saturday then upper ridging rebuilds for the second half of the weekend with dry and warmer conditions. Much like the pattern of the past week or two, models flatten the ridge again early next week for increasing onshore flow and cooler temperatures but generally dry conditions. Aviation Upper level trough moving through the area late today. Southwesterly flow aloft becoming northwesterly Wednesday morning. Low level onshore flow today increasing tonight behind the trough. |

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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. |
