DECEMBER 2016 CAN BE SUMMARIZED AS WETTER AND COOLER THAN NORMAL FOR
THE MEDFORD AREA WITH A FEW NOTABLE RECORDS DURING THE MONTH. THE
STRETCH OF DAYS WITH NON-FREEZING TEMPERATURES FINALLY CAME TO AN END
ON THE 5TH WHEN THE AIRPORT RECORDED 31 DEGREES. THIS IS THE LATEST
FIRST FREEZE DATE ON RECORD FOR THE MEDFORD AIRPORT. CONSEQUENTLY, THIS
ALSO SET A NEW RECORD FOR NUMBER OF DAYS WITHOUT FREEZING TEMPERATURES,
WHICH IS NOW 279 DAYS. RIGHT AROUND THIS TIME IS WHEN MEDFORD SAW IT`S
FIRST SNOWFALL OF THE SEASON WITH 0.4 INCHES RECORDED ON THE 6TH. THERE
WERE A FEW ADDITIONAL TRACES OF SNOWFALL REPORTED DURING THE MONTH,
SOME OF WHICH WERE DUE TO FOG SEEDING.

THE WEATHER PATTERN WAS FAIRLY ACTIVE FOR THE MONTH OVERALL. THERE WERE
SEVERAL SYSTEMS THAT MOVED THROUGH THE AREA, DELIVERING ENOUGH
PRECIPITATION TO LEAVE THE MONTH`S TOTAL ABOVE AVERAGE. ON THE 14TH,
ONE SYSTEM MOVED THROUGH BRINGING RECORD RAINFALL TO MEDFORD. OVER AN
INCH AND A HALF OF RAIN FELL THAT DAY, WHICH LED TO MANY RIVER RISES
AROUND THE FORECAST AREA. NUMEROUS AREAS AROUND THE ROGUE VALLEY HAD TO
DEAL WITH STANDING WATER ON ROADWAYS AND AREA PARKS HAD TO DEAL WITH
LOCAL CREEKS AND RIVERS SURPASSING THEIR BANKS FOR A BRIEF TIME.
SHORTLY AFTER THIS, A STRONG ARCTIC HIGH PRESSURE SETTLED OVER THE
AREA, BRINGING THE COLDEST TEMPERATURES OF THE SEASON THUS FAR. THIS
COLD AIR MASS WAS DRY ENOUGH TO SPARE THE ROGUE VALLEY OF FOGGY
CONDITIONS FOR A FEW DAYS. AFTER THIS BRIEF PERIOD OF QUIET WEATHER,
ANOTHER SYSTEM PASSED THROUGH, BRINGING A RECORD RAINFALL OF 1.05
INCHES TO THE MEDFORD AIRPORT ON THE 23RD.

ASIDE FROM A FEW WEAK SYSTEMS TO PASS THROUGH, THE WEATHER REMAINED
RATHER QUIET FOR THE REMAINDER OF THE MONTH. HOWEVER, SNOW BEGAN
FALLING SHORTLY AFTER THE BALL DROPPED IN MEDFORD AND 2017 WILL BEGIN
WITH SNOW ON THE GROUND FOR MOST WESTERN VALLEYS.
