updated fire weather discussion

Short term Short wave that moved across the region last night
is exiting the forecast area this morning into central washington.

Satellite shows clear skies behind this wave and expect sunshine
through the morning into early afternoon. Upper low is moving
into northern california and will continue to move northeast
across the region later this afternoon and evening. There is
plenty of instability aloft and surface temperatures will quickly
rise into the 80s and 90s with dewpoints in the 50s. Expect
showers and thunderstorms to develop this afternoon and continue
through the evening as the low moves through. Increasing surface
gradients with a marine push today into tonight will result in
breezy west winds. 94

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 Several fire weather concerns are anticipated
today, namely the thunderstorms that will develop this afternoon and
evening across central and northeast oregon and southeast
washington. Lals of 4 are anticipated and some storms may bring
gusts of 55 mph or stronger. Fire zones 640 and 644 will be most
susceptible to possible fire spread where fine fuels are considerably
dry. The winds will increase in most areas today. The relative
humidity for areas in and around the columbia basin will not be
critically low today, but winds and relative humidity will be
monitored closely. A drier westerly flow is expected on Tuesday with
occasionally breezy winds. Wister

Prev discussion issued 259 am pdt Mon jun 26 2017
short term... Today through Wednesday... A weakening upper low is
roughly near 40n 128w early this morning. This low will be kicked
through the pacific northwest during the next 24 hours by a larger
low moving into western canada. Moisture has been flowing into the
region from california since Sunday. A fair amount of mid and high
level cloud cover will continue to drift across the region this
morning. A few very light showers will accompany this cloud cover.

As the upper low approaches the region this afternoon it will cause
a marine push cool front to move east of the cascades. Thus the
combination of this boundary, increasing moisture and energy from
the system will cause isolated to scattered thunderstorms this
afternoon and the evening. The best coverages of storms will extend
from deschutes county east to grant county, and northeast to the
blue mountains, grande ronde valley and wallowa county. Spc
continues to indicate a marginal risk of severe thunderstorms for
portions of our area. Shear looks to be strong enough to produce
strong gusty winds and some hail from grant county northward and
northeastward late this afternoon and this evening. West of this
area, shear looks to be generally less than 30 kts with only general
thunderstorms expected. Breezy winds in the columbia river gorge
will gradually spread eastward today, especially in the afternoon
with the marine push cool front. Cooler and fair conditions are
expected Tuesday and Wednesday due to the return of a dry west to
northwest flow pattern. 90
long term... Wednesday night through Monday... An upper trough will
departing the region Wednesday night and it will be replaced by
building high pressure aloft again by Thursday night into Friday. At
first the flow will be from the northwest ahead of this upper ridge
which will first build off the coast before it moves eastward into
the region. This will keep temperatures from getting too warm.

However with building heights and 850 mb temperatures can still
expect warm conditions over the CWA on Thursday with a warming
trend. There may be locally breezy winds Wednesday evening but the
winds will become light overnight into Thursday. The warming trend
will continue through Friday and then temperatures after that will
be nearly steady with highs in the mid 80s to lower 90s in the lower
elevations and mostly 70s to lower 80s mountains. Precipitation is
not expected in the extended range forecast and winds will be light
throughout. 88
