...UNSEASONABLY COOL TEMPERATURES REST OF THE WEEK...

AN EARLY AUTUMN LIKE WEATHER SYSTEM WILL BE SETTLING OVER THE
REGION MIDWEEK AND CONTINUE INTO THE LABOR DAY WEEKEND. THIS WILL
LEAD TO UNUSUALLY COOL CONDITIONS THROUGH THIS PERIOD WITH HIGH
TEMPERATURES IN THE COLUMBIA BASIN IN THE 60S TO LOWER 70S WHILE
THE MOUNTAINS WILL SEE 50S AND 60S. OVERNIGHT LOW TEMPERATURES
WILL ALSO BE COOL WITH 40S IN THE BASIN AND UPPER 20S AND 30S IN
THE MOUNTAINS.

THE INITIAL COLD FRONT WILL MOVE THROUGH THE REGION ON WEDNESDAY
BRINGING A CHANCE OF PRECIPITATION. UNSTABLE CONDITIONS WILL LEAD
TO SOME MORE SHOWERS ON THURSDAY. PERHAPS THE BEST CHANCE FOR A
MORE WIDESPREAD RAIN WOULD COME LATE FRIDAY AND INTO SATURDAY AS
THE HEART OF THE COLD AIR MOVES OVER THE FORECAST AREA. SNOW
LEVELS DURING THIS TIME WILL LOWER TO AROUND 6500 FEET. THIS MEANS
THERE COULD BE A DUSTING OF SNOW IN THE HIGHER ELEVATIONS OF THE
WALLOWA, ELKHORN, STRAWBERRY AND CASCADE MOUNTAINS.

THOSE PLANNING OUTDOOR ADVENTURES SHOULD BE PREPARED FOR THE
COOLER CONDITIONS AND POTENTIAL PRECIPITATION.
