SYNOPSIS
MOSTLY DRY WEATHER IS EXPECTED THROUGH MUCH OF THE WEEK. WINDS WILL
BE BREEZY AT TIMES. TEMPERATURES WILL COOL SLIGHTLY THURSDAY, BEFORE
WARMING BACK UP TO END THE WEEK. A WEAK COLD FRONT WILL BRING A
CHANCE FOR LIGHT SHOWERS AND GUSTY WINDS ON WEDNESDAY NIGHT.
DISCUSSION
TONIGHT THROUGH SATURDAY NIGHT: A FAST MOVING SHORTWAVE WILL PASS
OVER THE REGION THIS EVENING, THAT WILL BRING A SLIGHT CHANCE OF
SHOWERS ACROSS THE REGION. RAIN TOTALS WILL BE LIGHT UNDER THESE
SHOWERS, GENERALLY SEEING LESS THAN 0.1 INCHES. THE BEST CHANCE WILL
BE OVER THE CASCADES AND NORTHERN IDAHO. WINDS WILL CONTINUE TO
INCREASE THIS AFTERNOON, WITH CONTINUED BREEZY CONDITIONS THROUGH
THE EARLY AFTERNOON ON THURSDAY. WIND GUSTS UP TO 20 TO 25 MPH WILL
BE EXPECTED AT MOST LOCATIONS. HUMIDITY WILL DROP INTO THE 20S
AGAIN THURSDAY, WITH TEENS POSSIBLE IN THE COLUMBIA BASIN AREAS.
UNFORTUNATELY, WINDS ON THURSDAY SHOULD REMAIN LIGHTER FROM THE
SOUTHWEST, WHICH WILL KEEP FIRE DANGER RELATIVELY CONTAINED.
A BRIEF RIDGE WILL BUILD BACK INTO THE AREA TO END THE WEEK BEFORE
THE NEXT SYSTEM STARTS TO MOVE IN LATE SATURDAY NIGHT. TEMPERATURES
WILL WARM BACK UP INTO THE 70S WITH HUMIDITY DROPPING INTO THE 20S
FOR THE LOWER ELEVATIONS. /KK

COOLER, WETTER PATTERN AS A DEEP CENTER OF LOW PRESSURE APPROACHES

LOW 70S, SEVERAL DEGREES COOLER THAN SATURDAY. BY MONDAY, HIGHS WILL
DROP INTO THE LOW 60S WHERE THEY'LL REMAIN THROUGH AT LEAST THE
MIDDLE OF NEXT WEEK. AN UNSTABLE ATMOSPHERE WILL BE FAVORABLE FOR
ISOLATED THUNDERSTORMS TO DEVELOP EACH AFTERNOON PRIMARILY OVER
HIGHER TERRAIN ALONG THE CANADIAN BORDER AND THROUGHOUT THE ID
