OCTOBER 2017 WAS A RELATIVELY QUIET MONTH, ESPECIALLY COMPARED TO
THE RECORD SETTING WET OCTOBER OF 2016. DURING THE FIRST FEW DAYS OF
THE MONTH, A WEAK FRONT MOVED THROUGH THE AREA. WHILE ONLY A TRACE
OF PRECIPITATION WAS REPORTED IN MEDFORD, THE FRONT DID BRING
COOLER, FALL-LIKE TEMPERATURES THROUGH THE FIRST WEEK. AFTERWARDS,
HIGH PRESSURE BUILT OVER THE AREA, MAINTAINING DRY CONDITIONS WITH
WARM DAYTIME HIGHS AND COLD OVERNIGHT LOWS. WITHOUT SIGNIFICANT
RAINS, FIRE SEASON CONTINUED UNTIL THE LATTER PART OF OCTOBER AND
SMOKY/HAZY CONDITIONS CONTINUED TO IMPACT THE ROGUE VALLEY.

BY MID-MONTH, A STRONG FRONT BROUGHT SIGNIFICANT RAIN AND COOLER
TEMPERATURES. THE MEDFORD AIRPORT RECORDED 0.89 INCHES OF RAIN
DURING THIS SYSTEM; THE ONLY PRECIPITATION RECORDED FOR THE WHOLE
MONTH. RECORD DAILY PRECIPITATION TOTALS WERE SET FOR OTHER
LOCATIONS AROUND THE FORECAST AREA. THE PLENTIFUL RAIN AND COOLER
TEMPERATURES FINALLY PUT AN END TO THE LONG 2017 FIRE SEASON.

THE COOLER, FALL-LIKE WEATHER WAS SHORT LIVED HOWEVER, AS HIGH
PRESSURE RESUMED CONTROL. THIS BROUGHT MUCH WARMER THAN NORMAL
TEMPERATURES THAT RESULTED IN A NEW RECORD HIGH TEMPERATURE AT THE
MEDFORD AIRPORT. 84 DEGREES WAS REPORTED ON THE 24TH, BREAKING THE
OLD RECORD OF 80 DEGREES SET IN 1965. WITH THE RECENT RAIN AND HIGH
PRESSURE ALOFT, MORNING FOG WAS A COMMON OCCURRENCE DURING THAT LAST
PORTION OF THE MONTH. THE FOG DID NOT LINGER HOWEVER, AND CLEAR DRY,
DAYS WRAPPED UP THE MONTH.
