FIRE WEATHER PLANNING FORECAST FOR THE SAN FRANCISCO BAY AREA AND
CENTRAL CALIFORNIA COAST
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
128 PM PDT SAT MAY 23 2026
DISCUSSION
A STRONG AND SLIGHTLY DEEPENING MARINE LAYER WILL
PUSH FARTHER INLAND INTO THE NIGHT LEADING TO STRONG HUMIDITY
RECOVERIES ACROSS THE DISTRICT. SPOTTY DRIZZLE WILL BE POSSIBLE
ALONG THE COAST AND WITHIN SOME OF THE NEAR-COASTAL PEAKS. CLOUD
COVER WILL BE SLOW TO ERODE EACH DAY INTO THE EARLY WEEK, LEADING
TO GOOD HUMIDITY RETENTIONS. BREEZY ONSHORE WINDS WILL DEVELOP
EACH AFTERNOON AND EVENING THROUGH THE WEEKEND WITH THE STRONGEST
WINDS IN THE INLAND VALLEYS AND PASSES. MORE WIDESPREAD COOLING
AND HIGHER HUMIDITIES ARE FORECAST THROUGH EARLY NEXT WEEK AS THE
MARINE LAYER CONTINUES TO STAY STRONG. THE UPPER LEVEL PATTERN
CHANGES INTO THE MID WEEK, LEADING TO ANOTHER WARMING AND DRYING
TREND.
NOTE : ALL WINDS ARE 20-FOOT WINDS UNLESS OTHERWISE SPECIFIED.
THUNDERSTORMS IMPLY STRONG, GUSTY AND ERRATIC WINDS.
