VALID 261700Z - 271200Z
MINOR MODIFICATIONS WERE MADE TO THE ISODRYT AREA BASED ON THE
LATEST OBSERVATIONS AND HIGH-RESOLUTION FORECAST GUIDANCE. THE
OREGON CASCADES BETWEEN EUGENE AND BEND AND NORTHWARD TO AROUND MT.
HOOD RECEIVED LIGHT RAIN YESTERDAY OVER MULTIPLE HOURS, WHICH WILL
MAKE SOME OF THE FUELS LESS RECEPTIVE, AND CLOUD COVER IS LIKELY TO
PERSIST OVER THIS AREA TODAY LEADING TO LESS CONFIDENCE IN THAT PART
OF THE ISODRYT AREA. HIGH-BASED SHOWERS WITH ISOLATED THUNDERSTORMS
PRODUCING SPORADIC LIGHTNING ARE POSSIBLE OVER PORTIONS OF NORTHWEST
OREGON AND WESTERN WASHINGTON OVERNIGHT. PLEASE SEE THE PREVIOUS
FORECAST FOR MORE DETAILS.

..SYNOPSIS
ONE OR MORE SUBTLE MIDLEVEL DISTURBANCES WILL OVERSPREAD THE
NORTHWEST TODAY, WHERE WELL-ESTABLISHED MONSOONAL MOISTURE IS IN
PLACE. THE ASSOCIATED FORCING FOR ASCENT AND SUFFICIENT BUOYANCY
SHOULD SUPPORT A MIX OF WET/DRY HIGH-BASED THUNDERSTORMS OVER THE
CASCADES DURING AFTERNOON INTO THE EVENING. WHILE THUNDERSTORM
COVERAGE MAY REMAIN SOMEWHAT LIMITED (POTENTIALLY 5-10 PERCENT), ANY
STORMS THAT FORM MAY POSE A RISK OF NEW IGNITIONS AND GUSTY/ERRATIC
OUTFLOW WINDS. A CONTINUATION OF MIXED WET/DRY THUNDERSTORMS IS
EXPECTED FARTHER SOUTH INTO NORTHERN CA, THOUGH SEVERAL DAYS OF RAIN
CASTS UNCERTAINTY ON FUEL RECEPTIVENESS -- PRECLUDING HIGHLIGHTS AT
THIS TIME.
