APRIL 2015 WAS CHARACTERIZED BY THE TYPICAL SHARP SWINGS IN WEATHER THAT COME
WITH SPRING. TEMPERATURES REMAINED ON THE COOLER SIDE OF NORMAL AS THE ACTIVE
PATTERN FROM MARCH CONTINUED INTO THE MIDDLE OF APRIL. A FAIRLY STRONG COLD
FRONT MOVED THROUGH THE AREA ON THE 7TH. WHILE MEDFORD ONLY RECEIVED RAIN WITH
THIS SYSTEM, OTHER LOCATIONS WITHIN THE COUNTY WARNING AREA, SUCH AS SISKIYOU
COUNTY, RECEIVED SIGNIFICANT SNOW. THIS INCLUDED LOWER ELEVATIONS THAT HAVEN`T
RECEIVED THAT MUCH SNOW IN A FEW WINTERS. ANOTHER STRONG COLD FRONT PASSED
THROUGH ON THE 13TH BRINGING STRONG GUSTY WINDS TO THE ROGUE VALLEY AND A SHARP
DROP IN TEMPERATURE; ABOUT 10-15 DEGREES IN JUST AN HOUR. AFTER THIS FRONT,
TEMPERATURES WARMED SIGNIFICANTLY AS HIGH PRESSURE SETTLED OVER THE REGION.
ALTHOUGH NO RECORDS WERE BROKEN, HIGH TEMPERATURES REACHED AS MUCH AS 15-20
DEGREES ABOVE NORMAL ACROSS THE AREA. THE LAST FRONT TO MOVE THROUGH DURING
APRIL WAS FAIRLY DRY, BUT DID MANAGE TO KNOCK TEMPERATURES DOWN TO NEAR NORMAL
VALUES IN MEDFORD FOR A FEW DAYS. HIGH PRESSURE MOVED IN TO FINISH APRIL OFF
WARMER THAN NORMAL, WITH THE WARMEST DAY OF THE YEAR SO FAR OCCURRING ON THE
27TH; 87 DEGREES WAS RECORDED AT THE MEDFORD AIRPORT.
