Short term Tonight through Wednesday night... Forecast area will
remain under a southerly flow tonight and Tuesday ahead of a trough
passage expected Tuesday night. Then the pattern will transition to
a dry westerly flow on Wednesday. There will continue to a slight
chance of showers or thunderstorms tonight mainly over the far
eastern mountains. Thunderstorm potential will increase late Tuesday
as the approaching upper level trough adds dynamic lift to an
already hot and unstable atmosphere. Tuesday evening looks like it
could be the most active thunderstorm period with activity lifting
to the northeast to east after midnight. There will be some
increasing westerly winds late Tuesday and overnight as cooler
marine air arrives in association with the trough passage. This will
lead to slightly cooler temperatures Wednesday and breezy winds.

Long term Thursday through Tuesday... Dry conditions under mostly
westerly flow are expected through a bulk of the extended period.

Will see some winds on the breezier side Thursday and Friday through
the gaps with weak cross-cascade thermal gradients, increasing to
locally windy through the gaps and breezy to locally windy downwind
of the gaps Friday night through early next week, especially during
the late afternoons early evenings with a deepening marine
layer strengthening onshore flow. Given antecedent hot and dry
conditions, these increasing winds may pose some problems for
controlling any wildfire starts in fine fuels for the basin and
northcentral oregon, although strict windrh criteria for red flags
may not be met with increasing marine influence. Daytime highs will
run 5 to 8 degrees above normal Thursday and Friday falling to near
normal for the remainder of the extended. Peck richards

Aviation 00z tafs...VFR conditions expected at all sites through
the remainder of the day and into Tuesday afternoon. A few showers
and weak thunderstorms have developed near kbdn & krdm and will
linger through 02z this evening before dry conditions return. Winds
sustained around 15kts with gusts up to 25kts will affect kdls
through tonight. Gusty winds will once again pick up for Tuesday
afternoon through the columbia river gorge and affect kdls. Will
need to keep an eye out for showers or a few thunderstorms affecting
kbdn & krdm late Tuesday afternoon, but precipitation looks to hold
off until after 00z Tuesday evening. Richards

Fire weather The potential for fire starts due to lightning will
increase late Tuesday through Wednesday as the upper level ridge
over the region breaks down. This will lead to scattered
thunderstorms Tuesday night across a large portion of the forecast
area but be more of a concern in the lower elevation dry fuels of
the columbia basin. Westerly winds will also increase late Tuesday
after the lightning which will aid in the potential spread of any
fires that are ignited by lightning. A fire weather watch has been
issued to cover this event.

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.
