MAY 2013 BEGAN WARM AND DRY UNDER HIGH PRESSURE...AND FELT LIKE
SUMMER CAME A LITTLE EARLY TO THE ROGUE VALLEY. AN UPPER LEVEL LOW
PROVIDED ENOUGH INSTABILITY TO RESULT IN THUNDERSTORMS AND RAIN FOR
A FEW DAYS DURING THE FIRST WEEK...BUT DID NOT PROVIDE RELIEF FOR
THE WARMER THAN NORMAL TEMPERATURES THAT REMAINED IN PLACE FOR THE
FIRST HALF OF THE MONTH. A SERIES OF SYSTEMS MOVED OVER THE REGION
DURING THE SECOND HALF OF MAY...WHICH RESULTED IN A SWITCH BACK TO A
PATTERN MORE REMINISCENT OF THE WET SEASON. AS A RESULT...COOLER
THAN NORMAL TEMPERATURES AND SEVERAL DAYS OF RAIN WERE RECORDED AT
THE MEDFORD AIRPORT. AS MAY CAME TO A CLOSE...CONDITIONS BECAME MORE
SEASONAL...BUT OVERALL MAY 2013 WILL BE KNOWN AS A DRIER AND WARMER
THAN NORMAL MONTH.
