Updated national weather service pendleton or 1038 pm pdt Tue jul 16 2019 updated aviation discussion Update A weak wave and trough is exiting the area this evening and a northwesterly flow is setting up behind it. The trough had little moisture or energy. So, I took out the showers along the washington cascade crest this evening as radar and webcams showed no precipitation and just some scattered flat cumulus. Also made some cloud cover adjustments to match up to satellite imagery better. With less cloud cover, adjusted overnight temperatures down a degree or so. Winds have been decreasing in the last hour or two as expected. Made a few minor adjustments there as well. Also bumped up winds a bit tomorrow afternoon as even stronger winds are expected then. Forecast update already out. Perry Aviation 06z tafs... Scattered mid level clouds will continue this evening before dissipating overnight. Scattered to broken high level clouds above 20k feet will be present overnight. Tomorrow afternoon and evening scattered to broken ceilings will return at 4- 8k feet with scattered to broken mid clouds at 10-15k feet. Winds will remain below 12 kts tonight. Winds will increase again after 15z tomorrow morning and reach 10-20 kts with gusts to 30 kts at all taf sites from late morning through early evening before decreasing after 04z. Perry Prev discussion issued 435 pm pdt Tue jul 16 2019 short term... Tonight through Friday... Broad west to northwest flow will be over the area through the forecast period. This will keep the region dry and warm except for some clouds and occasional very light rain along the immediate cascade crest. It will be breezy in the cascade gaps each afternoon and evening with winds peaking Thursday afternoon and evening. Winds could be 25-35 mph with gusts to 40 mph in the columbia gorge and kittitas valley during this time. This could present some localized fire weather concerns |

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. |
