...MEDFORD OREGON WEATHER REVIEW: FEBRUARY 2015...

THE MONTH OF FEBRUARY STARTED OUT WET AS MULTIPLE WARM SYSTEMS MOVED
THROUGH DURING THE FIRST WEEK, DELIVERING RECORD BREAKING RAINFALL. THE
FIRST SET OF SYSTEMS BROKE A DAILY RAINFALL TOTAL FOR MEDFORD ON THE
2ND WITH 0.67 INCHES OF RAIN MEASURED THAT DAY, FOLLOWED BY ANOTHER
0.60 INCHES ON THE 3RD. THIS RAINFALL SET THE STAGE FOR SIGNIFICANT
FLOODING, MAINLY FOR THE SOUTHERN AND WESTERN PORTIONS OF THE COUNTY
WARNING AREA, BY SATURATING THE GROUND AHEAD OF A SIGNIFICANT
ATMOSPHERIC RIVER EVENT. ANOTHER RAINFALL RECORD FOR MEDFORD WAS BROKEN
ON THE 6TH AS ANOTHER ROUND OF MOISTURE LADEN SYSTEMS MOVED THROUGH THE
AREA FROM THE 5TH THROUGH THE 9TH. ALTHOUGH THE WORST OF THE FLOODING
OCCURRED IN SISKIYOU COUNTY, CA, MULTIPLE RIVERS AND STREAMS REACHED
MINOR FLOOD STAGE ALONG WITH NUMEROUS ROAD WASHOUTS AROUND THE AREA.
STRONG WINDS ALSO ACCOMPANIED THE ONE SYSTEM THAT MOVED THROUGH ON THE
6TH. THIS COUPLED WITH SATURATED SOILS RESULTED IN NUMEROUS TREES
DOWNED AROUND THE AREA. AFTER THE DRENCHING RAINS DURING THE FIRST
WEEK, A RIDGE OF HIGH PRESSURE SETTLED OVER THE PACIFIC NORTHWEST THAT
KEPT THE AREA DRY AND WARM OVER THE NEXT TWO WEEKS. DURING THE LAST FEW
DAYS OF FEBRUARY, THE RIDGE RETROGRADED TO THE EAST, ALLOWING AN UPPER

TEMPERATURES, VALLEY RAIN, AND SOME MUCH NEEDED MOUNTAIN SNOW.
