Short term Tonight through Thursday. Upper low moving inland
this afternoon with a short wave moving across oregon. This wave
is currently the focus for showers and thunderstorms moving north
northeast at 25-35 mph. Expect most of the forecast area will be
impacted by showers and storms for the remainder of the afternoon
into the evening. Main threat will be hail, winds and heavy rain.

As the short wave moves off to the north overnight precipitation
will be ending with clearing skies. Moderate surface gradients
with a marine push will create breezy to locally windy conditions
through tonight into Tuesday. For Tuesday a drier westerly flow
aloft with partly to mostly sunny skies. Temperatures will be
about 10 degrees cooler with highs in the 80s. The flow aloft
becomes more northwesterly Wednesday and Thursday with continued
partly cloudy conditions. Temperatures will be closer to normal
levels with highs in the 80s and lows in the 40s and 50s. 94

Long term Thursday night through Monday... An upper level ridge
will build near the coast Thursday night then move inland and weaken
Friday as a short wave dives into mt. This wave will increase sky
cover Friday and Saturday in wallowa county but precipitation is
expected to remain east of the CWA Friday. A few showers may develop
over the eagle caps Saturday afternoon. Another ridge will build
offshore Saturday and then weaken as it moves through wa and or
Sunday. Temperatures will be nearly steady with highs in the mid 80s
to lower 90s in the lower elevations and mostly 70s to lower 80s
mountains. Coonfield

Aviation 18z tafs... A weather system and cold front will move
into the region today bringing scattered showers and
afternoon evening isolated thunderstorms. This may cause brief MVFR
conditions near and under thunderstorms due to lower CIGS and
visibility. OtherwiseVFR conditions will prevail during the next 24
hours. While TS are possible at krdm kbdn kpsc kpdt kalw the
probability remains too low to include in TAF at krdm and kbdn.

Winds will increase... Kdls now then spreading eastward to the
remaining TAF sites.

Fire weather Thunderstorms developing across the forecast area
are producing frequent lightning. There have also been reports of
heavy downpours and winds gusts as strong as 47 mph. Red flag
warnings are in effect for fire zones 640 and 644 which covers the
prineville district, the crooked river grasslands, the john day
valley and the grande ronde valley. Discussing with land management
agencies, even the grassy areas in the blue mountains and wallowa
mountains could be a concern for fire spread due to new lightning
starts and outflow winds. Storms have developed a little farther west
and north than anticipated along the east slopes of the oregon
cascades. The air mass in our western zones should begin to
stabilize as the westerly flow takes effect, and thunderstorms
should taper off this evening.

Another concern for fire weather are the winds this evening for
areas in and around the columbia basin. The lowest humidity is in
the hanford district where rhs are in the teens to lower 20s. Winds
are light at this time in this area but will increase over the next
several hours. The humidity should respond and also increase.

Conditions are borderline for red flag and will continue to
highlight in the forecast. Wister

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.
