SHORT TERM. Tonight through Wednesday . Upper trough is exiting the region this afternoon and an upper level ridge is building in behind it. The ridge will be the main weather feature through the day on Tuesday. This will result in a continuation of stratus and fog in the lower valleys. Have issued a dense fog advisory for the Columbia Basin and adjacent foothills and valleys for tonight and early Monday. The fog may become even more widespread Monday night and Tuesday with the ridge overhead. Away from the fog conditions will be fair with mild temperatures and just a few clouds. By Tuesday evening a weak frontal band will cross the Cascades for a chance of showers and mountain snow showers. However QPF amounts will be rather light Tuesday night. By late Wednesday the next much stronger system may reach the Cascade east slopes near the very end of the day for a chance of rain and mountain snow. The fog could linger in the Columbia Basin into Wednesday. 78
LONG TERM. Wednesday night through Sunday . Models in good agreement on an active pattern beginning Wednesday and continuing into the first half of next weekend. A wet storm system looks to impact the region Wednesday night through Friday, bringing widespread rain and mountain snow to the forecast area. Behind this system, a persistent moist, westerly flow will lead to continued chances for scattered precipitation through at least Saturday afternoon. Initially, snow levels for Thursday's system will range between 4000-6000 feet, gradually lowering to 500-1000 feet by Sunday morning. Ensembles showing the potential for QPF ranging between 0.50-1.50" through the weekend for the higher elevations, and ~0.30" possible on average for the Columbia Basin. As snow levels lower, may need to consider winter weather highlights, especially for the Cascades as well as higher terrain of central and northeast Oregon. A weak upper level ridge begins to move onshore by next Sunday, bringing a brief break from the active weather. With a Pacific flow, temperatures expected to remain near normal through next weekend with highs in the 40s and lows in the 20s/30s. Richards

Expect dense fog to once again develop and impact all taf sites except KBDN/KRDM. LIFR/IFR conditions expected for KPDT/KALW/KPSC/KYKM/KDLS with VFR conditions for KBDN/KRDM. Fog will remain dense across the Columbia Basin through the day Monday. Richards

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.
