INTO FRIDAY. MOST OF THE REGION WILL BE UNDER MILD, DRY
CONDITIONS TO END THE WEEK. SOME LINGERING SHOWERS ALONG THE
CANADIAN BORDER ARE POSSIBLE NEAR THE NORTHEAST WA AND NORTH ID.
WINDS WILL BE THE MAIN CONCERN FOR FRIDAY AS THE GULF OF ALASKA

A TIGHTENING GRADIENT WILL BRING BREEZY CONDITIONS AND ELEVATED
FIRE CONCERNS. WINDS WILL BE SOUTHWEST SUSTAINED IN THE TEENS

AREAS. HIGHS WILL BE IN THE 70S TO LOW 80S. LOWS WILL BE IN THE
40S.
WEEKEND THROUGH WEDNESDAY: ENSEMBLES CONTINUE TO BRING THE LOW
THROUGH THE REGION OF SATURDAY. IT WILL BE SLOW MOVING AND A
LIGHT PRECIP PRODUCER WITH 24 HOUR AMOUNTS LESS THAN A TENTH OF
AN INCH. WEAK INSTABILITY COULD BE HIGH ENOUGH TO GENERATE AN
ISOLATED LIGHTNING STRIKE ALONG THE NORTHERN MOUNTAINS. AREAS
IMPACTED BY THUNDERSTORMS COULD SEE HIGHER PRECIP AMOUNTS. COOLER
CONDITIONS ARE EXPECTED. WINDS WILL STILL BE BREEZY BUT WEAKER
THAN FRIDAY WITH GUSTS INTO THE 20 TO 30 MPH RANGE. FOR SUNDAY,
ENSEMBLES ARE LEANING TO A WEAK TROUGH OVER THE PACIFIC
NORTHWEST. IT WILL BRING COOLER TEMPERATURES WITH LIGHT SHOWER
ACTIVITY. ENSEMBLES ARE GOOD AGREEMENT FOR ANOTHER LOW IMPACTING
THE REGION TUESDAY AND WEDNESDAY. IT IS LOOKING TO BRING A
ROUND OF WIDESPREAD SHOWERS ACROSS THE INLAND NORTHWEST. IT IS
TOO EARLY TO TELL IF THERE WILL BE THUNDERSTORMS ASSOCIATED WITH
THE SYSTEM. OVERNIGHT LOWS ON SATURDAY AND SUNDAY NIGHTS WILL
CHILLY. POCKETS OF FROST IS CONCERN FOR THE CASCADES AND
NORTHERN VALLEYS AS THESE AREAS HAVE AROUND 40-60% PROBABILITY
OF BEING BELOW 35 DEGREES. LOWS REBOUND BACK INTO THE 40S FOR
THE START OF NEXT WEEK. HIGHS WILL BE IN THE 60S FOR SATURDAY.
SUNDAY AND START OF NEXT WILL HAVE HIGHS IN THE UPPER 60S AND
