JANUARY WAS AN INTERESTING MONTH. WITH ONGOING DROUGHT AREA WIDE,  
MANY WERE HOPING FOR THE WET DECEMBER TO CARRY INTO JANUARY.  
HOWEVER, DURING THE FIRST PART OF JANUARY, THE STORM TRACK SHIFTED  
AND WAS DIRECTED MORE INTO NORTHERN CALIFORNIA. THIS BROUGHT COPIOUS  
MOISTURE TO OUR SOUTHERN NEIGHBORS, INCLUDING MT. SHASTA CITY, WHERE  
MORE THAN 16 INCHES OF RAIN/MELTED SNOW FELL IN AN 11-DAY STRETCH  
FROM THE 4TH TO THE 14TH. AMAZINGLY, WITH ALL THAT PRECIPITATION,  
THE RIVERS, STREAMS AND CREEKS DOWN IN THAT AREA WERE ABLE TO HANDLE  
THE HIGHER FLOWS WITH MINIMAL FLOOD ISSUES. INSTEAD OF THE RAIN, THE  
MAIN WEATHER IMPACT IN SOUTHERN OREGON, AND ESPECIALLY HERE IN THE  
ROGUE VALLEY, WAS THE WIND. FOR THOSE SAME 11 DAYS, MEDFORD SAW WIND  
STORM AFTER WIND STORM WITH WINDS FROM THE SOUTHEAST IDEALLY ALIGNED  
WITH THE VALLEY. WIND SPEEDS WERE COMMONLY HIGHER THAN 35 MPH ON ALL  
BUT ONE OF THOSE DAYS WITH A PEAK WIND GUST OF 55 MPH RECORDED ON  
THE 4TH. THIS BROUGHT CONSIDERABLE WIND DAMAGE AND LOCAL POWER  
OUTAGES. SOUTHERN OREGON WASN'T WITHOUT PRECIPITATION AND THE  
COQUILLE RIVER AT COQUILLE ROSE NEAR AND ABOVE FLOOD STAGE FROM THE  
15TH TO THE 17TH PROMPTING FLOOD WARNINGS. BUT, PRECIPITATION JUST  
WASN'T NEARLY TO THE MAGNITUDE OF WHAT OCCURRED IN NORCAL DUE TO  
DOWNSLOPE TERRAIN EFFECTS. MEDFORD WAS ALSO QUITE MILD DURING THAT  
STRETCH OF WINDY WEATHER WITH HIGHS COMMONLY 55 DEGREES OR GREATER.  
THE PEAK OF THE WARMTH OCCURRED ON THE 12TH WITH A HIGH OF 66  
DEGREES. THE STORM DOOR CLOSED FOR THE ENTIRE AREA FROM MID-MONTH  
ONWARD AND LITTLE ADDITIONAL PRECIPITATION WAS MEASURED. SEVERAL  
COLD HIGH PRESSURE SYSTEMS BUILT IN EAST OF THE CASCADES RESULTING  
IN BOUTS OF AIR STAGNATION. BUT, THE COLD NIGHTS WERE THE STORY IN  
MEDFORD WITH LOWS COMMONLY IN THE 20S. THE LOWEST TEMPERATURE OF 17F  
WAS RECORDED ON THE 30TH. SOME AREAS EAST OF THE CASCADES HAD LOW  
TEMPERATURES OF 10 TO 15 DEGREES BELOW ZERO. SEA LEVEL PRESSURE WAS  
VERY HIGH, PEAKING AT 30.70 INCHES ON THE 25TH, WHICH WASN'T TOO FAR  
FROM THE RECORD OF 30.83 INCHES SET ON JANUARY 11, 2009.  
 
THE AVERAGE TEMPERATURE FOR THE MONTH WAS 41.3 DEGREES, WHICH IS 0.9  
DEGREES ABOVE NORMAL. THE AVERAGE MAXIMUM TEMPERATURE WAS 51.1  
DEGREES, WHICH IS 2.9 DEGREES ABOVE NORMAL. THE AVERAGE MINIMUM  
TEMPERATURE WAS 31.6 DEGREES, WHICH IS 0.9 DEGREES BELOW NORMAL. THE  
HIGHEST TEMPERATURE FOR THE MONTH WAS 66 DEGREES WHICH OCCURRED ON  
THE 12TH. THE LOWEST TEMPERATURE FOR THE MONTH WAS 17 DEGREES WHICH  
OCCURRED ON THE 30TH.  
 
THERE WERE 8 CLEAR DAYS, 18 PARTLY CLOUDY DAYS, AND 5 CLOUDY DAYS.  
 
TOTAL PRECIPITATION FOR THE MONTH WAS 0.76 INCHES WHICH IS 1.96  
INCHES BELOW NORMAL. TOTAL PRECIPITATION FOR THE WATER YEAR  
(BEGINNING OCTOBER 1ST) IS 7.33 INCHES WHICH IS 2.72 INCHES BELOW  
NORMAL. CALENDAR YEAR PRECIPITATION IS 0.76 INCHES WHICH IS 1.96  
INCHES BELOW NORMAL. NO SNOW FELL DURING THE MONTH.  
 
THE AVERAGE WIND SPEED FOR THE MONTH WAS 5.2 MPH. THE FASTEST  
RECORDED TWO-MINUTE WIND SPEED WAS 40 MPH FROM THE SOUTHEAST WHICH  
OCCURRED ON THE 4TH. THE PEAK WIND WAS 55 MPH FROM THE SOUTHEAST  
WHICH OCCURRED ON THE 4TH.  
 
THE HIGHEST PRESSURE FOR THE MONTH WAS 30.70 INCHES ON THE 25TH. THE  
LOWEST PRESSURE FOR THE MONTH WAS 29.27 INCHES ON THE 14TH.  
 
THE 66 DEGREES ON THE 12TH SET A DAILY MAXIMUM TEMPERATURE RECORD,  
ECLIPSING THE 65 DEGREES THAT OCCURRED IN 1986.
