AS THE OLD SAYING GOES, "MARCH COMES IN LIKE A LION AND LEAVES
LIKE A LAMB." MARCH 2018 LIVED UP TO THIS PROVERB IN MEDFORD,
BEGINNING WITH WIND, RAIN, AND EVEN SNOW ON THE 1ST, THEN AFTER A
MONTH OF COOLER THAN NORMAL TEMPERATURES AND MULTIPLE PERIODS OF
RAIN, ENDING WITH WARM TEMPERATURES AND SUNNY SKIES ON THE 31ST.

THE WINDY, WET, AND COOL START TO THE MONTH ARRIVED DUE TO A
POTENT COLD FRONT THAT SWEPT QUICKLY THROUGH THE AREA ON THE 1ST
AND 2ND. HIGH PRESSURE THEN KEPT THE REGION DRY AND COOL FOR
ABOUT A WEEK BEFORE ANOTHER QUICK MOVING STORM SYSTEM PASSED
THROUGH THE REGION ON THE 8TH AND 9TH. BOTH SYSTEMS PRODUCED OVER
A QUARTER OF AN INCH OF RAIN, BUT ONLY THE FIRST FRONT MANAGED TO
BRING A TRACE OF SNOW TO MEDFORD.

FOLLOWING A FEW QUIET DAYS, A DEEP, SLOW MOVING UPPER LEVEL
TROUGH TOOK UP RESIDENCE OVER SOUTHERN OREGON ON THE 13TH,
RESULTING IN A WEEK OF COOL, WET WEATHER FOR MEDFORD. THE TROUGH
FINALLY WEAKENED AND EXITED TO OUR EAST BY THE 19TH, BUT HIGH
PRESSURE LASTED ONLY A DAY OR TWO BEFORE ANOTHER LARGE UPPER LEVEL
TROUGH DUG IN OVERHEAD ON THE 21ST. ANOTHER WEEK OF COOL AND WET
WEATHER FOLLOWED, FULLY SECURING A COOLER THAN NORMAL MONTH WITH
ENOUGH RAIN TO JUST BARELY MISS REACHING THE NORMAL MARCH
PRECIPITATION.

BEHIND THE DEPARTING TROUGH, HIGH PRESSURE WAS FINALLY ABLE TO
TAKE CONTROL, PRODUCING SEVERAL WARM AND SUNNY DAYS AND A MUCH
CALMER END TO THE MONTH OF MARCH.
