DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE DENVER CO
438 PM MST FRI DEC 09 2016

...MODERATE DROUGHT CONDITIONS SLOWLY EXPAND ON THE NORTHEAST
COLORADO PLAINS...

SYNOPSIS...

HIGH PRESSURE AND ABNORMALLY WARM TEMPERATURES FINALLY GAVE WAY TO A
COOL NORTHWEST FLOW THE WEEK BEFORE THANKSGIVING. THIS RESULTED IN
THE MOUNTAIN SNOWPACK BUILDING THE PAST COUPLE WEEKS. HOWEVER...THE
EASTERN PLAINS HAVE NOT BENEFITTED FROM THIS WEATHER PATTERN LIKE
THE HIGH COUNTRY HAS.

LOCAL AREAS AFFECTED...

ON DECEMBER 6TH...MODERATE DROUGHT WAS EXPANDED TO INCLUDE
PHILLIPS...SEDGWICK...NORTHEAST LOGAN AND NORTHERN WASHINGTON
COUNTIES ON THE NORTHEAST PLAINS ON THE U.S. DROUGHT MONITOR. WINTER
WHEAT GERMINATION HAS BEEN VERY SPOTTY IN THESE AREAS.

SEVERE DROUGHT /D2/ CONTINUED IN THE FORT
COLLINS...LOVELAND...ESTES PARK...RUSTIC AND THE HIGH FOREST AREAS
TO THE NORTHWEST IN LARIMER COUNTY AND ALSO ON THE EAST CENTRAL
PLAINS IN LINCOLN COUNTY CENTERED AROUND LIMON.

MODERATE DROUGHT /D1/ CONDITIONS CONTINUED IN THE MOUNTAINS EAST OF
THE DIVIDE...FRONT RANGE FOOTHILLS AND URBAN CORRIDOR EXTENDING
EASTWARD ACROSS THE EASTERN PLAINS. ABNORMALLY DRY CONDITIONS
EXTENDED ACROSS THE REMAINDER OF THE NORTHEAST COLORADO PLAINS.

AGRICULTURAL IMPACTS...

SOIL MOISTURE CONTINUED TO LAG BEHIND LAST YEAR. RAIN AND SNOW
SHOWERS RECENTLY HAVE PROVIDED RELIEF TO THE ENDURING DRY
CONDITIONS. HOWEVER...WINTER WHEAT AND PASTURE CONDITIONS REMAIN A
CONCERN IN AREAS THAT HAVE NOT RECEIVED ADEQUATE MOISTURE THE PAST
SEVERAL MONTHS.

HYDROLOGIC SUMMARY...

THE SNOWPACK IN THE NORTH CENTRAL COLORADO ROCKIES HAS IMPROVED. THE
MID NOVEMBER MOUNTAIN SNOWPACK WAS THE LOWEST IN NEARLY 40 YEARS OF
RECORD...ONLY 4 TO 12 PERCENT OF NORMAL. BY DECEMBER 9TH THE
MOUNTAIN SNOWPACK HAD IMPROVED TO 72 PERCENT OF NORMAL IN THE UPPER
COLORADO RIVER BASIN...70 PERCENT OF NORMAL IN THE NORTH PLATTE
BASIN AND 64 PERCENT OF NORMAL IN THE SOUTH PLATTE BASIN.

COMBINED RESERVOIR STORAGE REMAINED IN GOOD SHAPE AT 105 AND 102
PERCENT OF AVERAGE...RESPECTIVELY IN THE UPPER COLORADO AND SOUTH
PLATTE BASINS AT THE END OF NOVEMBER.

STREAMFLOW IS MOSTLY IN THE NORMAL RANGE FOR THIS TIME OF YEAR
EXCEPT FOR SOME GAGES IN THE HEADWATERS OF THE COLORADO RIVER BASIN.

CLIMATE SUMMARY...

AFTER ABNORMALLY WARM AND DRY CONDITIONS THE PAST SEVERAL MONTHS...A
WINTER STORM DECEMBER 6TH AND 7TH BROUGHT 6 TO 10 INCHES OF SNOWFALL
IN AREAS OF THE FRONT RANGE FOOTHILLS. LESSER AMOUNTS FELL ON THE
PLAINS WITH SNOWFALL RANGING FROM 1 TO 4 INCHES.
