IN THE LATE FALL OF 2015 A STAGNANT JET STREAM PATTERN LED TO COLD
TEMPERATURES IN THE WESTERN UNITED STATES AND WARM TEMPERATURES IN
THE EAST. THIS PATTERN WAS REMARKABLY STABLE RIGHT THROUGH THE MONTH
OF DECEMBER. THE TEMPERATURES WERE ABOVE NORMAL AT THE NATIONAL
WEATHER SERVICE OFFICE IN GRAY FROM DECEMBER 2 THROUGH 28, WITH THE
WARMTH PEAKING ON CHRISTMAS DAY WHEN THE TEMPERATURE REACHED 58
DEGREES. COLDER AIR FINALLY ARRIVED AFTER CHRISTMAS WITH THE FIRST
SIGNIFICANT SNOWFALL OF THE SEASON OCCURRING ON DECEMBER 29. COOLER
CONDITIONS LASTED INTO EARLY JANUARY BEFORE A STORM SYSTEM BROUGHT
HEAVY RAIN AND WARM TEMPERATURES ON THE 10TH, NEARLY ELIMINATING THE
WINTER SNOW PACK. ANOTHER STORM BROUGHT HEAVY SNOW ON JANUARY 12 AND
13 WITH THE PATTERN ONCE AGAIN TURNING COLDER. FOR 13 STRAIGHT DAYS
THE TEMPERATURE NEVER ROSE ABOVE FREEZING. BUT BY THE END OF THE
MONTH WARMER WEATHER BEGAN TO RETURN. THIS WARMER WEATHER PERSISTED
INTO EARLY FEBRUARY BEFORE ANOTHER STORM SYSTEM BROUGHT 6.6 INCHES
OF SNOW ON FEBRUARY 5. THIS WAS THE FIRST IN A SERIES OF STORM
SYSTEMS WHICH BROUGHT LIGHT SNOW AND PROGRESSIVELY COLDER
TEMPERATURES. BY FEBRUARY 11 A BRUTALLY COLD ARCTIC AIR MASS MOVED
INTO THE REGION WITH THE TEMPERATURE FALLING BELOW ZERO ON 4
STRAIGHT NIGHTS. THE TEMPERATURE HIT 12 BELOW ZERO ON FEBRUARY 13
AND 14, THE COLDEST TEMPERATURE ON RECORD IN THE MONTH OF FEBRUARY.
BUT THE BRUTAL COLD DID NOT LAST MUCH LONGER. ANOTHER STORM SYSTEM
BROUGHT LIGHT SNOW CHANGING TO RAIN AS TEMPERATURES WARMED ON THE
16TH. WARM WEATHER DOMINATED THE LAST HALF OF THE MONTH WITH THE
WINTER SNOW PACK DWINDLING DOWN TO JUST A TRACE BY THE END OF THE
MONTH. THE HIGH TEMPERATURE OF 56 DEGREES ON FEBRUARY 29 WAS THE
WARMEST TEMPERATURE ON RECORD IN THE MONTH OF FEBRUARY.

THE AVERAGE TEMPERATURE FOR THE WINTER WAS 29.3 DEGREES WHICH WAS
5.0 DEGREES ABOVE NORMAL. THE WARMEST WINTER ON RECORD WAS 2001-02
WHEN THE AVERAGE TEMPERATURE WAS 29.9 DEGREES. THE COLDEST WAS JUST
LAST YEAR WHEN THE AVERAGE TEMPERATURE WAS ONLY 19.8 DEGREES.

A TOTAL OF 12.82 INCHES OF PRECIPITATION FELL WHICH WAS 1.92 INCHES
ABOVE NORMAL. THE HEAVIEST PRECIPITATION WAS ON JANUARY 9 AND 10
WHEN 2.60 INCHES OF RAIN AND MELTED SNOW WAS MEASURED. THE WETTEST
WINTER ON RECORD WAS 2007-08 WHEN 15.28 INCHES WAS RECORDED. THE
DRIEST WAS 2006-07 WITH ONLY 7.17 INCHES.

THERE WAS 37.1 INCHES OF SNOWFALL WHICH WAS 18.9 INCHES BELOW
NORMAL. THE HEAVIEST SNOW OF THE SEASON WAS ON JANUARY 12 AND 13
WHEN 8.8 INCHES WAS MEASURED. THE SNOWIEST WINTER WAS 2007-08 WHEN
