(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 ksew 221629 afdsew area forecast discussion national weather service seattle wa 930 am pdt Sat jul 22 2017 Synopsis Higher pressure aloft will build over the region through tonight with dry conditions and diminishing cloud cover starting this afternoon. Low level onshore flow will return for dry weather and moderate temperatures through much of next week. Short term An upper level low off the coast of northern bc was drifting northeast this morning and is expected to continue to do so through tonight. An associated weak shortwave wiggled onshore into bc overnight bringing clouds into western washington and some very light rain from the northern olympic peninsula to the northern cascades. As of mid morning, the precipitation was tapering off and should see the Sun reappear in many locations this afternoon. Have adjusted the forecasts to reflect these short-term conditions. What's left of the upper low is expected to move inland across western canada later tonight through Sunday night. This change should encourage some stronger low level onshore flow that will bring more marine cloudiness into western washington overnight and Sunday morning. Then ridging aloft with rising heights should ease the onshore flow for more sunshine and warmer daytime temps Monday. No significant rain in sight. Buehner Long term From the previous discussion... a split in the flow Tuesday will allow for upper level ridging to be the main weather feature for W wa while an upper level low spins up off the ca coast... Allowing for the prospect for precip to climb north into or. Current models look to be in agreement that nothing associated with this low will make it as far north as wa... But given its proximity this may be a feature to keep an eye on in future runs. The upper ridge pushes east Wed with an upper trough expected over the area for thu. Models in agreement that this troughiness will linger into the weekend... But not much in the way of precip expected for the area. This level of activity for the second half of the upcoming week will allow for temps to fall a few degrees allowing for more mild summer weather over W wa. Smr |
Aviation The base of an eastward-moving upper trough will brush by western washington through Sunday, with moderate westerly flow aloft. A moist low-level air mass is in place, with dewpoints toppoing out near 60f over the lowlands this afternoon. Could lead to sea fog near the strait, including the vicinity of clm. Elsewhere, CIGS will lift some this afternoon, but abundance of moisture will lead to easy development of CU field. Ksea... S-sw wind will become northerly around 00z-02z, with northerly flow then continuing through Sunday and beyond. CIGS will rise slowly today. Any clearing will be somewhat temporary given the moistness of the air mass, since cumulus will easily fill back in. Should be a few hours of clearing this evening, but then the moistness of the air mass will probably lead to CIGS in the 010-020 range on Sunday morning. Haner Marine A surface high pressure ridge was nudging inland this morning across southwest washington, leading to light gradients. This ridge will become re-establish near the northern end of vancouver island this evening, leading to a northerly component to our wind and pressure field. Moderate onshore flow will also develop this afternoon and evening, with small craft advisory strength winds through the strait tonight. Moderate onshore flow will then continue through at least Monday, with a daily repeat each evening of sca strength winds through the strait and NW wind over the coastal waters. A particularly moist low-level air mass is arriving this afternoon, with surface dewpoints near 60f later today. Especially over the cooler waters of the eastern strait of juan de fuca, this could lead to the development of sea fog. Dewpoints will come down a couple degrees on Sunday, so extent of sea fog should diminish a bit tomorrow. Haner Sew watches warnings advisories Wa... None. Pz... Small craft advisory from 6 pm this evening to 3 am pdt Sunday for central u.S. Waters strait of juan de fuca-east entrance u.S. Waters strait of juan de fuca. |

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. |
