...A WARM AND MOSTLY DRY OCTOBER...

OCTOBER 2014 WAS THE SECOND WARMEST ON RECORD AT THE AIRPORT AND THE
THIRD WARMEST IN THE BOISE AREA SINCE RECORD KEEPING BEGAN IN 1865.
MOST OF THE MONTH WAS MORE TYPICAL OF MAY WITH HIGHS REACHING OR
EXCEEDING 70 ON 18 DAYS AND 80 ON 4 DAYS. AND OVERNIGHT LOWS WERE
ALL ABOVE FREEZING...ALTHOUGH THE NORMAL FIRST FROST DATE IS OCTOBER
10. TEMPERATURES AVERAGED BELOW NORMAL ON ONLY 3 DAYS.

PRECIPITATION WAS A LITTLE MORE THAN 50% OF NORMAL WHICH RANKS AS
THE 17TH DRIEST OCTOBER AT THE AIRPORT AND TIES FOR 35TH PLACE AT
ALL BOISE LOCATIONS GOING BACK 148 YEARS.

SUNSHINE WAS ABUNDANT THROUGHOUT THE MONTH. THE 23RD WAS THE ONLY

THE WARM DRY WEATHER REFLECTED THE RIDGE OF WARM AIR ALOFT WHICH
DOMINATED THE WESTERN U.S. THROUGH MOST OF THE MONTH. AS IS TYPICAL
OF FALL...PACIFIC WEATHER DISTURBANCES MANAGED TO PUNCH THROUGH THE
RIDGE ON SEVERAL OCCASIONS...BRINGING COOLER BREEZY WEATHER BUT
