...EUGENE 2014 WEATHER IN REVIEW...

================================================================
MONTHLY WEATHER RECAPS...

JANUARY...A RATHER UNEVENTFUL MONTH OF WEATHER...WITH OVERALL
    A RATHER TYPICAL JANUARY. INCOMING FRONTS WERE WEAK...AND
    BROUGHT LESS THAN NORMAL RAINFALL.  HIGH PRESSURE MID MONTH
    GAVE REGION STRING OF COOL DAYS AND NIGHTS FROM THE 13TH
    THROUGH THE 23TH. HEAVY FOG THAT FORMED AT NIGHT PERSISTED
    WELL INTO THE FOLLOWING DAY DURING THIS PERIOD.

FEBRUARY...AFTER A VERY MILD START...ARCTIC AIR FILTERED INTO
    THE REGION...BRINGING VERY COLD AIR. TEMPERATURES STAYED
    BELOW FREEZING FROM THE 5TH UNTIL THE 9TH. OCCASIONAL SNOW
    FELL ON THE 6TH AND 7TH...WITH EUGENE AIRPORT GETING 8.7
    INCHES OF SNOW. TO MAKE IT WORSE...FREEZING RAIN BROUGHT
    DOWN TREES AND POWER LINES ON THE 8TH AND 9TH. SIGNIFICANT
    DAMAGE WAS REPORTED ACROSS MUCH OF THE AREA...WITH NO
    POWER IN MANY RURAL AREAS FOR SEVERAL DAYS. MUCH WARMER
    AIR RETURNED ON THE 10TH AND 11TH...WITH HIGHS WARMING
    INTO THE MID 50S BY THE 12TH. REGULAR FRONTS THROUGH THE
    END OF MONTH KEPT REGION WET...WITH TEMPERATURES MILD.
    THE STRONGEST FRONT BROUGHT GUSTY SOUTH WINDS OF 40 TO 50
    TO THE SOUTH WILLAMETTE VALLEY ON THE 15TH INTO THE 16TH.

MARCH...MARCH ROARED IN LIKE A LION...WITH WIND AND RAIN.
    WIND GUSTS OF 45 TO 50 MPH ON THE 6TH BROUGHT SOME TREE
    DAMAGE AND FEW POWER OUTAGES. IT WAS A MILD AND WET MONTH.
    STRONGEST FRONT DROPPED 1.01 INCHES OF RAIN ON THE 28TH.

APRIL...RATHER NICE MONTH OF WEATHER. TEMPERATURES WARMED IN
   THE 70S SEVERAL TIMES...AND EVEN THE LOWER 80S ON THE 30TH.
   RAINFALL WAS NEAR NORMAL...WITH MOST RAIN FALL BETWEEN THE
   21ST AND 27TH.

MAY...MAY CONTINUED WHERE APRIL ENDED...WARM. IT WAS 88 DEG
    ON THE FIRST...THE WARMEST MAY 1ST SINCE 1947. BUT IT DID
    NOT LAST. MORE TYPICAL MAY LIKE TEMPERATURES RETURNED BY
    BY THE 3RD...WITH HIGHS IN THE 60S. ANOTHER BRIEF BURST
    OF HEAT OCCURRED ON THE 13TH TO 15TH...WITH TEMPERATURE
    PEAKING IN THE MID 80S.

JUNE...OVERALL...RATHER NORMAL AND UNEVENTFUL JUNE. HOWEVER
    A FUNNEL CLOUD WAS REPORTED NEAR LEBANON ON THE 17TH.

JULY...HIGH PRESSURE OVER THE NORTHEAST PACIFIC GREW STRONGER IN
    JULY. THIS MAINTAINED A RELATIVELY DRY AIR MASS OVER THE AREA.
    BUT ONSHORE FLOW WAS NOT AS STRONG AS NORMALLY EXPECTED. SO
    EVENING COOLING WAS NOT AS PRONOUNCED...LEAVING MANY NIGHTS
    IN THE UPPER 50S TO LOWER 60S. SMOKE FROM THE WILDFIRES OVER
    SOUTHWEST OREGON BROUGHT HAZE AT TIMES. WHILE MOST DAYS WERE
    DRY...THUNDERSTORMS ON 12TH...13TH AND 31ST BROUGHT BRIEF
    DOWNPOURS. ON THE 13TH...LIGHTNING DISRUPTED POWER AND A
    FEW FIRES TO HOUSE AND TREE IN BOTH CORVALLIS AND ALBANY.
    IT WAS THE 2ND WARMEST JULY...WITH AVERAGE TEMP OF 70.8 DEG.

AUGUST...AUGUST CONTINUED WHERE JULY ENDED...DRIER THAN NORMAL.
    UPPER LOW PRESSURE OFF THE SOUTH OREGON COAST BECAME THE
    DOMINANT WEATHER PATTERN. THIS PATTERN MAINTAINED A WARM
    AND HUMID SOUTHERLY FLOW OVER WESTERN OREGON THROUGH MUCH OF
    THE MONTH. AFTERNOON/EVENING THUNDERSTORMS OVER THE CASCADES
    DRIFTED INTO THE SOUTH WILLAMETTE VALLEY FROM TIME TO TIME.
    OVERALL...MOST MISSED THE AIRPORT...BUT BRIEF DOWNPOURS
    WERE REPORTED IN PLACES. MORE NOTABLE WERE THE ABUNDANT
    NEW FIRES STARTED IN THE WILLAMETTE NATIONAL FOREST. THE
    LARGEST WAS THE DECEPTION POINT...A COMPLEX OF LIGHTNING
    STARTED FIRES NEAR OAKRIDGE. SMOKE WAS A FREQUENT VISITOR
    TO THE EUGENE/SPRINGFIELD AREA LATE IN THE MONTH.

    WARM HUMID SOUTHERLY FLOW ALOFT BROUGHT UNUSUALLY HIGH
    DEWPOINT TEMPERATURES TO THE REGION. EUGENE AUGUST LOWS
    ARE NORMALLY NEAR 50 DEG...BUT WITH THE HUMID AIR IN PLACE
    TEMPERATURES RARELY DROPPED BELOW 55. IN PART DUE TO THE
    WARMER NIGHTS...AUGUST 2014 FINISHED AS THE 2ND WARMEST
    AUGUST ON RECORD (DATING BACK TO 1890).

SEPTEMBER...STARTED DRY AND WARM...WITH HIGHS WELL INTO THE
    80S THROUGH THE 15TH. INCREASING FRONTS FROM THE PACIFIC
    BEGAIN ARRIVING BY THE 20TH...WITH OCCASIONAL RAIN.
    MOST ALL OF THE MONTHS RAINFALL OCCURRED ON 23RD TO 24TH.
    SMOKE FROM WILDFIRES IN THE CASCADES AND SOUTHWEST OREGON
    OCCASIONALLY DRIFTED OVER THE AREA.

OCTOBER...STARTED WARM AND DRY...WITH NO RAIN FOR THE FIRST
    10 DAYS. SERIES OF FRONT ARRIVED BY THE 11TH...BRING MORE
    SEASONABLE TEMPERATURES AND RAIN. IN FACT...IT RAIN ON
    EVERY DAY AFTER THE 12TH. A STRONG FRONT BROUGHT VERY
    HEAVY RAINFALL TO THE REGION ON 22ND AND 23RD....WITH
    GENERALLY 1 TO 2 INCHES OF RAIN ACROSS THE AREA.
    ANOTHER STRONG FRONT ARRIVED ON THE 25TH...BRINGING GUSTY
    SOUTH WINDS. WITH TREES STILL HEAVY WITH LEAVES...THE
    40 TO 50 MPH WIND GUSTS BROKE TREE LIMBS AND KNOCKED OUT
    POWER TO THOUSANDS IN THE SOUTH WILLAMETTE VALLEY.

    AVERAGE OCTOBER TEMPERATURE WAS 59.2 MAKES OCTOBER 2014
    THE WARMEST OCTOBER ON RECORD. PREVIOUS RECORD WAS 57.4
    DEG WAY WAY BACK IN OCTOBER 1901.

NOVEMBER...IT WAS A RATHER BENIGN MONTH...AS TEMPERATURES WERE
    NEAR NORMAL. EARLY ARCTIC OUTBREAK OVER THE ROCKIES AND
    PLAINS STATES BROUGHT PUSHED COLD AIR WESTWARD INTO THE
    PAC NW. WHILE IT WAS NOT EXTRAORDINARILY COLD...THE AIR
    MASS DID RESULT IN STRONG OFFSHORE FLOW WITH STRONG EAST
    WINDS ACROSS THE REGION FROM THE 10TH TO 15TH...AND EAST
    WINDS CONTINUING BUT LIGHTER FROM 16TH TO 20TH. THE
    LIGHTER WINDS ALLOWED FOR BETTER HEAT LOSS AT NIGHT...
    WITH OVERNIGHT TEMPERATURES DOWN NEAR 20 DEG. MOISTURE
    MOVING NORTH FROM CALIFORNIA INTO OREGON FELL INTO THE
    COLD AIR ON THE 12TH TO 14TH...RESULTING IN FREEZING
    RAIN WITH LIGHT ACCUMULATIONS OF ICE. MORE SIGNIFICANT
    ICE ACCUMULATIONS WERE JUST NORTH OF EUGENE...FROM THE
    CENTRAL COAST RANGE ACROSS ALBANY INTO THE COBURG HILLS.

DECEMBER...STARTED RATHER TYPICAL...WITH CHILLY NIGHTS AND
    COOL DAYS. A STRONG FRONT PUSHED ACROSS THE REGION ON THE
    4TH...BRINGING 1 TO 2 INCHES OF RAIN. THE STORM TRACK
    THEN SHIFTED...PUSHING STRONG STORMS INTO CALIFORNIA.
    METRO AREA WAS NOT AS WET...BUT WAS MUCH MILDER. A STRONG
    STORM DEVELOPED OFFSHORE ON THE 11TH...AND BROUGHT A
    BRIEF PERIOD OF VERY STRONG SOUTH WINDS. WINDS ACROSS
    THE METRO AREA BROKE TREE LIMBS...TOPPLED MORE TREES
    AND KNOCKED OUT POWER TO TENS OF THOUSANDS OF HOMES. THE
    EUGENE AIRPORT RECORDED A GUST TO 55 MPH. MILD WEATHER
    CONTINUED THROUGH THE 24TH. ANOTHER BOUT OF HEAVY RAINS
    FELL ON THE 19TH TO 21ST...WITH 2 TO 3 INCHES OR RAIN IN
    EUGENE...BUT 6 TO 8 INCHES FELL OVER THE COAST RANGE.
    THIS CAUSED MANY RIVERS TO RISE...WITH FLOODING ON THE
    SIUSLAW AND MARYS RIVERS.

    ARCTIC HIGH PRESSURE ENDED THE MONTH ON A COLD BUT HIGH
    NOTE. HIGHEST PRESSURE FOR 2014 WAS 30.71 INCHES WHICH
    OCCURRED ON THE 30TH. IT WAS THE 2ND HIGHEST FOR ANY
    DECEMBER...AND CLOSE TO THE DECEMBER RECORD OF 30.72 SET
    ON DEC 14 1997.
