…ISOLATED TO WIDELY SCATTERED HIGH-BASED STORMS LATE TONIGHT
AND THURSDAY IN OREGON ZONES 611, 640, and 642…

…SCATTERED TO NUMEROUS STORMS THURSDAY AFTERNOON AND EVENING
ACROSS OREGON ZONES 644 and 645…

.Isolated to widely scattered high-based thunderstorms, capable
of producing abundant lightning, are anticipated to develop or
move into central Oregon late tonight. A low chance of wetting
rains (less than 50 percent) is associated with these storms. A
lull in thunderstorm potential then exists during the early to
late morning.

Another round of thunderstorms with greater coverage is then
forecast Thursday afternoon and evening stretching from central
OR through the Wallowas. While isolated to widely scattered storms
are more likely than not across central Oregon, scattered to
numerous storms are anticipated over the central Blue mountains
and areas east. More wet than dry storms are anticipated across
eastern Oregon capable of wetting rains (greater than 80%). High-
end amounts approaching or exceeding 1 inch are possible (20-40
percent confidence).

* AFFECTED AREA…Fire Weather Zones 611 Deschutes National
Forest -minus Sisters Ranger District, 640 Central Mountains
of Oregon and 642 Southern Blue and Strawberry Mountains.

* 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 45 mph.
A Red Flag Warning means that critical fire weather conditions
are either occurring now, or will shortly. A combination of
strong winds, low relative humidity, and warm temperatures can
contribute to extreme fire behavior.
