DESPITE APRIL 2016 SEEING SEVERAL HIGH TEMPERATURE RECORDS, IT IS
BESTDESCRIBED AS A STANDARD TRANSITIONAL MONTH FROM THE SOGGIER
WINTER MONTHSTOWARD THE WARMER AND DRIER SUMMER PATTERN. THE
BEGINNING OF THE MONTHSTARTED OFF WITH WELL ABOVE NORMAL
TEMPERATURES AND A FEW WEAK SYSTEMSWHICH BROUGHT LIGHT SHOWERS TO
THE AREA. THEN, WINDS TURNED OFFSHORE BRINGINGMUCH WARMER AND DRIER
AIR TO MEDFORD BETWEEN THE 6TH AND THE 8TH. SEVERAL RECORDHIGH
TEMPERATURES WERE BROKEN ACROSS SOUTHERN OREGON AND NORTHERN
CALIFORNIADURING THIS TIME. IN FACT, BOTH MEDFORD AND ROSEBURG ALSO
SET THE RECORD FORTHE EARLIEST 90 DEGREE DAY WHICH OCCURRED ON THE
7TH. TEMPERATURES QUICKLYSHIFTED BACK TOWARD NORMAL OVER THE NEXT
FEW DAYS AS A STRONG COLD FRONTPROGRESSED THROUGH. THIS COLD FRONT
BROUGHT ABOUT A HALF AN INCH OF RAINFALLTO 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 DAYSAND WET, COOL DAYS. IT IS WORTH NOTING THAT HIGH TEMPERATURE
RECORDSWERE BROKEN AT THE MEDFORD AIRPORT AGAIN ON THE 17TH AND THE
18TH INCLUDING ASECOND 90 DEGREE DAY AS ANOTHER THERMAL TROUGH MOVED
INLAND. FINALLY, AFTERSEVERAL SHOWERY DAYS TO CLOSE OUT THE MONTH, A
THIRD THERMAL TROUGH PATTERNSET UP ON THE 30TH TO CLOSE OUT APRIL
