MUCH LIKE APRIL, MAY OF 2025 ENDED WITH BELOW NORMAL PRECIPITATION
AND AVERAGED ABOVE NORMAL TEMPERATURES. DRY AND WARM CONDITIONS
CONTINUED INTO THE START OF MAY, BUT TEMPERATURES TRENDED COOLER
AROUND THE 3RD AS A WEAK FRONT MOVED THROUGH THE REGION. THERE WAS
NO MEASURABLE PRECIPITATION WITH THIS FRONT FOR MEDFORD. HIGH
PRESSURE FOLLOWED FOR THE NEXT WEEK, BRINGING DRY CONDITIONS AND
WARMER TEMPERATURES THAT WERE MORE TYPICAL OF LATE JUNE THAN EARLY
MAY. ANOTHER FRONT PASSED THROUGH THE REGION ON THE 11TH AND 12TH AS
UPPER LEVEL LOW PRESSURE PASSED THROUGH THE PACIFIC NORTHWEST. THIS
SYSTEM DELIVERED ALMOST THE ENTIRETY OF OF THE MONTHLY PRECIPITATION
FOR MEDFORD WHEN 0.52" OUT OF THE MONTHLY TOTAL OF 0.55" FELL
BETWEEN THE 11TH AND 12TH. ADDITIONALLY, SNOW LEVELS WERE LOW ENOUGH
TO DELIVER THE FIRST MEASURABLE SNOWFALL AT CRATER LAKE SINCE EARLY
APRIL.
A FEW ADDITIONAL WEAK FRONTS PASSED THROUGH IN NORTHWEST FLOW
THROUGH AROUND THE 20TH, AND IT WAS DURING THIS TIME THAT MEDFORD
RECORDED THE REMAINING 0.03" OF THE MONTHLY PRECIPITATION.
TEMPERATURES REMAINED ON THE COOLER SIDE OF NORMAL DURING THIS TIME.
DRY CONDITIONS PERSISTED THROUGH THE LAST THIRD OF THE MONTH WITH
TEMPERATURES HOVERING AROUND SEASONAL NORMALS. FOR THE LAST FEW DAYS
OF THE MONTH, HOWEVER, HIGH TEMPERATURES BECAME MORE TYPICAL OF
JULY, AND MEDFORD RECORDED IT`S FIRST 90 DEGREE DAY OF THE YEAR ON
MAY 27TH WHEN THE HIGH TEMPERATURE REACHED 96 DEGREES.
