URGENT - FIRE WEATHER MESSAGE
National Weather Service Pendleton OR
1225 PM PDT Thu Jul 23 2026

...HIGH ABUNDANT LIGHTNING RISK WITH THUNDERSTORMS TODAY... ...
WINDY AND BREEZY WITH CRITICAL RH FRIDAY AND SATURDAY...

The upper level low offshore will shift to the east just enough
to allow for monsoonal moisture to move into the region.
Instability will accompany the moisture and allow for increased
chances of isolated to scattered thunderstorms across the eastern
mountains. Brief heavy downpours, gusty outflow winds in excess
of 45 mph, small hail, and frequent lightning will be possible. A
strong to briefly severe thunderstorm cannot be ruled out this
afternoon and early evening.

Friday the upper level low will eject into the region bringing
windy conditions to many of the Cascade Gaps as well as central
OR. Humidities both Friday and Saturday will be critical.
