AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
302 PM PDT FRI MAY 1 2026
SYNOPSIS
WARM AND DRY CONDITIONS ARE EXPECTED TO CONTINUE OVER THE
WEEKEND. TEMPERATURES REMAIN ON TRACK TO WARM INTO THE UPPER
70S TO MID 80S BY SUNDAY INTO MONDAY. DRY AND COOLER, BUT STILL
SEASONABLY WARM WEATHER, LOOKS TO LINGER THROUGH THE REMAINDER
OF NEXT WEEK.
SHORT TERM /TONIGHT THROUGH SUNDAY NIGHT/
WARM AND DRY CONDITIONS CONTINUE WITH TEMPERATURES WARMING IN
THE LOW TO MID 70S FOR MUCH OF THE INTERIOR THIS AFTERNOON. AN
UPPER LEVEL LOW REMAINS OFFSHORE AND WILL PUSH SOME HIGH CLOUDS
OVER THE INTERIOR OF WESTERN WASHINGTON THROUGH THIS EVENING.
SOME INCREASING LIGHT ONSHORE FLOW WILL PROVIDE SOME STRATUS
ALONG THE COAST SPREADING INLAND SATURDAY MORNING. STRATUS
SHOULD DISSIPATE BY THE AFTERNOON HOURS LEAVING ANOTHER WARM AND
DRY DAY, WITH HIGH TEMPERATURES WARMING SLIGHTLY IN THE MID TO
UPPER 70S WITH WIDESPREAD AREAS OF MINOR HEATRISK ACROSS THE
INTERIOR. PROGRESSING INTO SUNDAY, TEMPS WILL WARM EVEN FURTHER
WITH AREAS IN THE LOW 80S AND MID 80S WITH AREAS OF MODERATE
HEATRISK. THE WARMEST AREAS CORRELATED WITH MODERATE HEATRISK
ARE GENERALLY PLACES IN THE SOUTHWEST INTERIOR AND AREAS IN THE
CASCADE VALLEYS.
MODERATE HEATRISK IMPACTS INCLUDE THOSE SENSITIVE TO THE HEAT
AND WHO MAY BE WITHOUT ADEQUATE COOLING. ADDITIONALLY, THOUGH IT
WILL BE WARM OUTSIDE, IT IS IMPORTANT TO REMEMBER THAT AREA
STREAMS, RIVERS, LAKES AND THE OCEAN, INCLUDING PUGET SOUND, WILL
STILL HAVE VERY COLD TEMPERATURES OFTEN AROUND 50 DEGREES OR
COLDER. PLEASE BE CAUTIOUS AROUND COLDER WATER DESPITE THE AIR
TEMPERATURES. RELATIVE HUMIDITY ALSO LOOKS TO BE UNSEASONABLY
LOW ACROSS WESTERN WASHINGTON ON SUNDAY. THIS POSES AN ELEVATED
RISK OF FIRE DANGER PRIMARILY AMONG DRY GRASSES OR DEAD AND DRY
VEGETATION.
LONG TERM /MONDAY THROUGH FRIDAY/
WARM AND DRY CONDITIONS
CONTINUE ON MONDAY WITH INCREASED ONSHORE FLOW, HIGH
TEMPERATURES WILL DROP, BUT WILL STILL REMAIN WARM, IN THE UPPER
70S. TEMPERATURES WILL STAY IN THE LOW 70S THROUGHOUT THE
REMAINDER OF THE WEEK - WITH NO PRECIPITATION EXPECTED AT THIS
TIME.
