.Dry southwest flow will bring gusty winds and low relative
humidities to the region again Friday afternoon and evening.

* Affected Area...In Idaho, Fire Weather Zones 423 Owyhee
Mountains and 426 Southern Highlands. In Oregon, Fire Weather
Zones 636 Burns BLM and 637 Vale BLM.

* Temperatures...Up to 75.
A strong storm system for this time of the year will bring
moderate to strong winds through this evening. Because the best
chance for precipitation will remain west of the Cascades,
relative humidities will be low and this in combination with winds
could result in critical conditions for eastern portions of Lake
and Modoc counties, and into western Harney County. Winds will be
strong again on Friday, but humidity values will be higher.
* IMPACTS...Strong winds combined with critically low relative
humidity can lead to the rapid growth and spread of new and
existing fires. Outdoor burning is banned during fire season.
* AFFECTED AREA...The eastern half of California Fire Weather Zone
285, this includes Alturas. The eastern part of Oregon Fire

...STRONG TO SEVERE THUNDERSTORMS WILL IMPACT THE CASCADE
MOUNTAINS TODAY, EXTENDING TO THE EASTERN SLOPES, WHILE
SOUTHEASTERN OREGON SEES DRY, WINDY, AND UNSTABLE CONDITIONS...
.A potent weather system will bring a myriad of impacts to the
forecast area today. For the Cascade Mountains and east slopes,
strong to severe thunderstorms will trek across primarily the
spine of the Cascades starting in the afternoon down around
central Oregon, advancing northward into the Washington Cascades
by the evening. While storms along the Cascades are expected to
be accompanied by a significant wetting rain, isolated to
scattered storms extending into the east slopes and portions of
the Columbia Basin will be much drier, leading to critical fire
weather conditions due to abundant lightning with a lack of
wetting rain.
For southeastern Oregon, this same weather system will usher in
hot and dry desert air, leading to breezy winds combined with low
RHs and locally unstable conditions. Showers and storms are not
anticipated to track as far east as southeastern Oregon.
Users should note that OR641 and WA691 are under partial Red Flag
Warnings. The Warned zones include only the western half of each
zone, and not the entirety of the zone.
* AFFECTED AREA...Fire Weather Zone 641 Lower Columbia Basin of
Oregon.
* IMPACTS...Thunderstorms will be capable of producing frequent
cloud-to-ground lightning and erratic, gusty outflow winds.
This combination will promote conditions conducive to new fire
starts and rapid fire spread for new and existing fires.
* THUNDERSTORMS...Abundant lightning with frequent cloud-to-
ground lightning strikes.
* OUTFLOW WINDS...Gusty winds up to 50 mph.
SVRPQR
The National Weather Service in Portland has issued a
* Severe Thunderstorm Warning for...
North central Clackamas County in northwestern Oregon...
West central Hood River County in northwestern Oregon...
Southeastern Multnomah County in northwestern Oregon...
Southeastern Clark County in southwestern Washington...
Southwestern Skamania County in southwestern Washington...
* Until 530 PM PDT.
* At 503 PM PDT, severe thunderstorms were located along a line
extending from 6 miles west of Lolo Pass to near Estacada, moving
north at 40 mph.
HAZARD...60 mph wind gusts and quarter size hail.
SOURCE...Trained weather spotters.
IMPACT...Hail damage to vehicles is expected. Expect wind damage
to roofs, siding, and trees.

Camas, Troutdale, Skamania, Mount Hood Village, Estacada, North
Bonneville, Multnomah Falls, Boring, Corbett, Fairview, Wood
Village, Dodson, Warrendale, and Bonneville Fish Hatchery. In
