JANUARY 2013 WAS WARMER AND WETTER THAN AVERAGE. STRONG WESTERLY
CHINOOK WINDS AT THE SURFACE WITH A NORTHWESTERLY FLOW ALOFT WERE
ASSOCIATED WITH WARMER THAN AVERAGE TEMPERATURES. TEMPERATURES
TURNED COLDER THAN AVERAGE ONLY FOR A FEW DAYS FOLLOWING A PAIR OF
SIGNIFICANT WINTER STORMS WHICH OCCURRED JAN 10TH TO 11TH AND ON JAN
29TH. ALTHOUGH SNOWFALL WAS OBSERVED ON TEN DAYS THIS MONTH...THESE
TWO STORMS ACCOUNTED FOR NEARLY ALL THE MONTHLY TOTAL PRECIPITATION.
NEW DAILY RECORDS FOR SNOWFALL WERE SET ON JAN 10TH WITH 5.9 INCHES
AND ON JAN 29TH WITH 5.5 INCHES. A NEW DAILY RECORD HIGH TEMPERATURE
OF 56 WAS SET ON JAN 26.
