...APRIL 2016 GOES IN THE BOOKS AS WARMEST APRIL ON RECORD FOR PDX...

...APRIL 2016 TEMPERATURES WERE ABOUT AVERAGE...FOR MAY...

...THIS IS THE 9TH TIME PORTLAND AIRPORT HAS SET OR TIED A RECORD
FOR WARMEST AVERAGE MONTHLY TEMPERATURE SINCE 2014...


NOW THAT APRIL 2016 HAS COME TO AN END...IT IS OFFICIAL NOW THAT
PORTLAND AIRPORT HAS SET A NEW MONTHLY RECORD FOR WARMEST APRIL
SINCE RECORDS BEGAN IN 1940. THE MONTHLY AVERAGE OF 57.8 DEGREES
SHATTERED THE PREVIOUS APRIL RECORD OF 56.3 DEGREES SET BACK IN 2004
BY A DEGREE AND A HALF.

TO PUT THIS INTO FURTHER CONTEXT...THE AVERAGE MONTHLY TEMPERATURE
FOR THE MONTH OF MAY IS ABOUT 58 DEGREES. IN OTHER WORDS...APRIL
2016 WAS ABOUT AS WARM AS AN AVERAGE MAY...ESPECIALLY IMPRESSIVE
CONSIDERING SPRING IS A TRANSITION SEASON WHERE MONTHLY AVERAGES
RAMP UP QUICKLY FROM WINTER TO SUMMER.

RECORD BREAKING WARMTH HAS NOT BEEN A STRANGER TO PORTLAND THE PAST
COUPLE YEARS...IN FACT APRIL 2016 IS NOW THE 9TH MONTH THAT HAS SET
OR TIED A RECORD FOR WARMEST AVERAGE MONTHLY TEMPERATURE SINCE THE
BEGINNING OF 2014. FRAMED ANOTHER WAY...ABOUT 30 PERCENT OF THE
MONTHS SINCE JANUARY 2014 HAVE EITHER TIED OR SET THEIR RESPECTIVE
RECORDS.

HERE IS AN UPDATED LIST OF THE RECORDS FOR WARMEST AVERAGE
TEMPERATURE FOR EACH CALENDAR MONTH...

                                              1981-2010
MONTH            YEAR / RECORD                  NORMAL

DECEMBER         1950 / 46.4                     40.4


IT IS IMPORTANT TO NOTE THAT THE PERIOD OF RECORD FOR PORTLAND
AIRPORT BEGAN IN 1940. SITES WITH LONGER PERIODS OF RECORD...SUCH AS
SALEM OR EUGENE...DID NOT SET NEW APRIL RECORDS DUE TO VERY WARM
APRILS IN 1926 AND 1934. HOWEVER APRIL 2016 STILL FELL IN THE TOP
FIVE FOR MOST OF OUR CLIMATE SITES.

MAY IS OFF TO A HEAD START WITH HIGH TEMPERATURES EXPECTED TO REACH
THE LOWER TO MID 80S TODAY AND MONDAY...ABOUT 15 TO 20 DEGREES ABOVE
NORMAL.

...MEDFORD OREGON WEATHER REVIEW: APRIL 2016...

DESPITE APRIL 2016 SEEING SEVERAL HIGH TEMPERATURE RECORDS, IT IS BEST
DESCRIBED AS A STANDARD TRANSITIONAL MONTH FROM THE SOGGIER WINTER MONTHS
TOWARD THE WARMER AND DRIER SUMMER PATTERN. THE BEGINNING OF THE MONTH
STARTED OFF WITH WELL ABOVE NORMAL TEMPERATURES AND A FEW WEAK SYSTEMS
WHICH BROUGHT LIGHT SHOWERS TO THE AREA. THEN, WINDS TURNED OFFSHORE BRINGING
MUCH WARMER AND DRIER AIR TO MEDFORD BETWEEN THE 6TH AND THE 8TH. SEVERAL RECORD
HIGH TEMPERATURES WERE BROKEN ACROSS SOUTHERN OREGON AND NORTHERN CALIFORNIA
DURING THIS TIME. IN FACT, BOTH MEDFORD AND ROSEBURG ALSO SET THE RECORD FOR
THE EARLIEST 90 DEGREE DAY WHICH OCCURRED ON THE 7TH. TEMPERATURES QUICKLY
SHIFTED BACK TOWARD NORMAL OVER THE NEXT FEW DAYS AS A STRONG COLD FRONT
PROGRESSED THROUGH. THIS COLD FRONT BROUGHT ABOUT A HALF AN INCH OF RAINFALL
TO THE MEDFORD AIRPORT OVER A FOUR DAY PERIOD BETWEEN THE 11TH AND THE 14TH.

OTHERWISE, THE SECOND HALF OF APRIL SAW SEVERAL SWINGS BETWEEN WARM, DRY DAYS
AND WET, COOL DAYS. IT IS WORTH NOTING THAT HIGH TEMPERATURE RECORDS
WERE BROKEN AT THE MEDFORD AIRPORT AGAIN ON THE 17TH AND THE 18TH INCLUDING A
SECOND 90 DEGREE DAY AS ANOTHER THERMAL TROUGH MOVED INLAND. FINALLY, AFTER
SEVERAL SHOWERY DAYS TO CLOSE OUT THE MONTH, A THIRD THERMAL TROUGH PATTERN
SET UP ON THE 30TH TO CLOSE OUT APRIL WITH ONE LAST MILD AND DRY DAY.

THE AVERAGE TEMPERATURE FOR APRIL WAS 58.3 DEGREES, WHICH IS 5.5
DEGREES ABOVE NORMAL. THE AVERAGE MAXIMUM TEMPERATURE WAS 72.1 DEGREES,
WHICH IS 7.2 DEGREE ABOVE NORMAL. THE AVERAGE MINIMUM TEMPERATURE WAS
44.4 DEGREES, WHICH IS 3.6 DEGREES ABOVE NORMAL. THE HIGHEST TEMPERATURE FOR
THE MONTH WAS 91 DEGREES ON THE 7TH AND 18TH. THE LOWEST TEMPERATURE OF THE
MONTH WAS 34 ON THE 26TH.

THERE WERE 16 CLEAR DAYS, 9 PARTLY CLOUDY DAYS, AND 5 CLOUDY DAYS.

TOTAL PRECIPITATION FOR THE MONTH WAS 0.96 INCHES, WHICH IS 0.42 INCHES
BELOW NORMAL. THE GREATEST 24 HOUR TOTAL WAS 0.37 INCHES THAT FELL FROM
THE 13TH THROUGH THE 14TH. THE WATER YEAR (BEGINNING OCTOBER 1ST)
STANDS AT 18.42 INCHES WHICH IS 3.25 INCHES ABOVE NORMAL. CALENDAR YEAR
PRECIPITATION IS NOW 8.66 INCHES WHICH IS 1.13 INCHES ABOVE NORMAL.

THE AVERAGE WIND FOR THE MONTH WAS 4.4 MPH. THE FASTEST RECORDED TWO-
MINUTE WIND WAS 35 MPH FROM THE SOUTHWEST ON THE 13TH. THE PEAK WIND
WAS 47 MPH FROM THE SOUTHWEST, ALSO ON THE 13TH.

THE HIGHEST PRESSURE FOR THE MONTH WAS 30.56 INCHES ON THE 5TH. THE
LOWEST PRESSURE FOR THE MONTH WAS 29.57 INCHES ON THE 22ND.
