NATIONAL WEATHER SERVICE SACRAMENTO CA
203 AM PDT SAT MAY 23 2026
...ELEVATED FIRE WEATHER CONDITIONS IN THE VALLEY SATURDAY
THRU MONDAY AND AGAIN TUESDAY THRU WEDNESDAY DUE TO LOW HUMIDITY

BELOW NORMAL BY TUESDAY. A FEW ISOLATED SHOWERS OR THUNDERSTORMS
ARE POSSIBLE OVER THE WEEKEND FOR THE SIERRA CREST AND NORTHERN
COASTAL RANGE, BUT MAINLY DRY WEATHER IS EXPECTED. WEST-SOUTHWESTERLY

IS FORECAST FOR TUESDAY AND WEDNESDAY, WHICH WILL BRING INCREASED
CONCERNS FOR ELEVATED FIRE WEATHER CONDITIONS FOR THE VALLEY.
