AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
337 PM PDT WED JUN 11 2025
SYNOPSIS
AFTER SEVERAL WARM DAYS, MORE SEASONABLE WEATHER IS
EXPECTED OVER THE NEXT WEEK. TEMPERATURES WILL REMAIN IN THE 60S
AND 70S ACROSS MOST OF THE REGION. OUTSIDE OF SOME LIGHT DRIZZLE
ALONG THE COASTAL AREAS, THE NEXT NOTEWORTHY CHANCE FOR
PRECIPITATION WILL ARRIVE MONDAY OR TUESDAY NEXT WEEK.
SHORT TERM /TONIGHT THROUGH FRIDAY NIGHT/
MARINE STRATUS
BURNED OFF MID-DAY, BUT MID AND HIGH LEVEL CLOUDS HAVE SPREAD
ACROSS THE REGION BLUNTING DAYTIME HEATING TODAY. THE FORECAST
WAS UPDATED EARLIER TO LOWER HIGHS TODAY AND MANY AREAS WILL
STRUGGLE TO REACH 70.
LOOKING FORWARD, GENERAL TOUGHING OVER THE REGION WILL KEEP FLOW
ONSHORE THURSDAY AND FRIDAY. MOISTURE IS LIMITED SO SOME COASTAL
DRIZZLE IS POSSIBLE, BUT OTHERWISE PRECIPITATION CHANCES WILL
REMAIN FAIRLY LOW. TEMPERATURES WILL REMAIN SIMILAR TO TODAY'S
LEVELS.
LONG TERM /SATURDAY THROUGH WEDNESDAY/
STRENGTHENING HIGH
PRESSURE WILL ALLOW TEMPERATURES TO WARM SLIGHTLY OVER THE
WEEKEND, WHILE STILL REMAINING COMFORTABLE AND DRY.
HIGH PRESSURE WEAKENS BY MONDAY & TUESDAY, AND TOUGHING ONCE
AGAIN BEGINS TO DOMINATE. THIS PERIOD MAY SEE SLIGHTLY BETTER
CHANCES FOR PRECIPITATION ACROSS THE REGION, THOUGH ANY AMOUNTS
STILL APPEAR LIGHT. THE MAIN THREAT WOULD BE SLICK ROAD
CONDITIONS THANKS TO AN EXTENDED DRY PERIOD ALLOWING OILS TO
BUILD UP. OTHERWISE THERE IS LITTLE TO NO INDICATION OF ANY
SIGNIFICANT HAZARDS OVER THE NEXT WEEK.
