SHORT TERM. Today through Friday. Short wave will be exiting the region this morning. Rain and snow will be tapering off. Inversion and light winds remain over the Columbia basin and valleys with fog continuing through the morning. Satellite indicating a short break before the next system moves into the Pacific northwest by afternoon. This system is a large upper low with a strong westerly jet which will impact the region through Friday. The initial front will move through later this afternoon and evening with a period of rain and higher elevation snow. For tonight through Friday a strong mid level westerly flow will bring heavy precipitation to the Cascades. Models indicate several short waves in the flow moving across the region over the next few days. This will result in periods of rain and mountain snow for the remainder of the forecast area as well. The northeast Oregon mountains will have a fairly good upslope component and will also receive a decent amount of precipitation. Snow levels will be around 4-5000 feet today and Thursday lowering to 3-4000 feet by Friday. Surface winds will be increasing from the southwest Thu into Fri. This will help mix out the fog in the lower elevations. 94

LONG TERM. Friday night through Wednesday . A shortwave trough is forecast to move across the area Friday night and Saturday with a chance for mainly mountain snow showers. Snow levels will be 2-3 thousand feet. There will be a lingering slight chance for mountain snow showers on Sunday. Otherwise A ridge of high pressure will build over the region for Monday and Tuesday for mostly dry conditions. Temperatures will be close to normal for this time of year. On Wednesday an upper level low will undercut the ridge and turn the upper flow southerly. This will increase moisture and result in a chance of showers and mountain snow showers with snow levels 1500-3000 feet. As of now the models are not depicting any major storms during this forecast period. 78

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.
