6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported. 5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive. 5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds. |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 kpqr 261657 afdpqr area forecast discussion national weather service portland or 955 am pdt Tue sep 26 2017 Synopsis High pressure will build into eastern washington and oregon resulting in offshore flow and warmer temps through Thursday. The next chance for rain comes around Friday, as a weakening cold front moves into the pac nw. Showers and cooler weather will continue into the weekend. Short term Today through Thursday..Patchy fog around in the southern valley this morning, but that will give way to sunshine by afternoon as high pressure builds inland and a thermal trough develops along the coast today and tonight. Pressure gradients are showing a good offshore trend this morning as offshore flow develops. This will result in warmer conditions today and Wednesday. Wednesday should be the warmest day along the coast but models are in good agreement that a flow reversal will occur along the southern oregon coast beginning Wednesday night so temperatures will be cooler along the coast on Thursday with low stratus and fog returning. Some marine air may get into the southern willamette valley Thursday morning but not enough to prevent another warm day inland. In response to an approaching upper trough the thermal trough will move inland Thursday night and the marine layer should deepen bringing some clouds inland through Friday morning. Thus, the warm weather will end for at least the freezable future. Schneider Long term No changes. Previous discussion follows... Thursday night through Monday... Southwesterly flow across the region Thursday night and Friday as an upper trough advances through the forecast area. Forecast models in general agreement with a weakening front pushing across the area. Boosted pops even further as 00z models are in better agreement for late in the week and weekend with a cool trough transiting the region sat. After the weekend however, models then diverge a bit for the first half of next week, so have maintained some low end pop chances for the start of next week in a nod to the ecmwf solution which provides for a deeper upper trough with more moisture (compared to the direr GFS solution). Expect that temperatures will trend back to slightly below seasonal normals for |
the weekend through early next week. Mh cullen Aviation There are some pockets of fog and low stratus producing ifr conditions this morning along some of the coastal river valleys as well as west of eugene. The stratus and fog will lift and dissipate by late morning. Otherwise, most of the area isVFR with abundant sunshine. ExpectVFR conditions everywhere this afternoon and tonight. Kpdx and approaches...VFR conditions expected today and tonight. Marine Thermal low pressure over southwest oregon will push northward along the coast today and bring some gusty north winds this evening and tonight over the outer waters and inland waters south of cascade head. Wind gusts will be in the 20-25 kt range in these areas. The thermal low pressure pushes inland Wednesday for decreasing winds. Winds will remain light Wednesday into the weekend. Towards the end of weekend and the beginning of next week there is still considerable model uncertainty with the ecmwf indicating gusty southerlies ahead of the next system to move through the area while the GFS continues the northerlies. Seas will remain 4 to 5 through the week until later in the weekend when a system moving in will bring increasing seas across our waters. Tw Pqr watches warnings advisories Or... None. Wa... None. Pz... Small craft advisory for winds from 8 pm this evening to 2 am pdt Wednesday for waters from CAPE shoalwater wa to cascade head or from 10 to 60 nm. Small craft advisory for winds from 5 pm this afternoon to 8 am pdt Wednesday for waters from cascade head to florence or from 10 to 60 nm.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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. |
