DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE NORMAN OK
755 AM CST WED FEB 1 2017


...MODERATE TO SEVERE DROUGHT COVERS MOST OF NORTHERN...CENTRAL
AND SOUTHEAST OKLAHOMA...

...A SMALL PART OF SOUTHEAST OKLAHOMA IS EXPERIENCING EXTREME
DROUGHT...

...PARTS OF SOUTHWEST OKLAHOMA AND WESTERN NORTH TEXAS ARE
ABNORMALLY DRY...

SYNOPSIS...

ACCORDING TO THE U.S. DROUGHT MONITOR...DATED 24 JANUARY
2017...MODERATE TO SEVERE DROUGHT COVERED MUCH OF THE NORTHERN HALF
OF OKLAHOMA OR AREAS NORTH OF INTERSTATE 40. SIMILAR DROUGHT
CONDITIONS EXTENDED ACROSS A LARGE PART OF SOUTHEAST OKLAHOMA.
PARTS OF BRYAN AND ATOKA COUNTIES ARE WITHIN EXTREME DROUGHT.
SOUTHWEST OKLAHOMA AND WESTERN NORTH TEXAS ARE ABNORMALLY DRY.


THE U.S. DROUGHT MONITOR USES FIVE CLASSIFICATIONS...LABELED D0-D4.

DROUGHT LEVELS...
D0 -- ABNORMALLY DRY OR RECOVERING FROM DROUGHT
D1 -- MODERATE DROUGHT
D2 -- SEVERE DROUGHT
D3 -- EXTREME DROUGHT
D4 -- EXCEPTIONAL DROUGHT

A GRAPHICAL DEPICTION OF DROUGHT CONDITIONS MAY BE FOUND ONLINE AT
THE NATIONAL WEATHER SERVICE NORMAN HOME PAGE AND THE UNITED STATES
DROUGHT MONITOR PAGE.

CLIMATE SUMMARY... ALTHOUGH MOST DAYS DURING THE NEW YEAR HAVE BEEN
DRY...A FEW PRECIPITATION EVENTS BROUGHT MUCH NEEDED MOISTURE TO
OKLAHOMA AND WESTERN NORTH TEXAS.  MOST OF THE PRECIPITATION FELL
DURING A THREE DAY PERIOD DURING THE MIDDLE OF THE MONTH.
UNFORTUNATELY...MOST OF THIS FELL AS FREEZING RAIN ACROSS THE
NORTHERN HALF OF OKLAHOMA. THE END RESULT HOWEVER WAS SOME
IMPROVEMENT IN DROUGHT CONDITIONS ACROSS MOST OF OKLAHOMA.  SINCE
THE MIDDLE OF THE MONTH...ANOTHER PERIOD OF VERY DRY WEATHER HAS
ENSUED.

THE CURRENT DROUGHT CAN BE TRACED BACK TO THE MIDDLE OF 2016 OR THE
BEGINNING OF SUMMER. DURING THE SUMMER MONTHS...SEVERAL HEAVY
RAINFALL EVENTS OCCURRED...SOME OF WHICH PRODUCED FLOODING. HOWEVER
PARTS OF SOUTHEAST OKLAHOMA MISSED OUT ON MOST OF THE RAIN.

THE FALL BROUGHT WELL ABOVE AVERAGE TEMPERATURES AND MOST OF THE
BENEFICIAL RAIN EVENTS OCCURRED ACROSS SOUTH CENTRAL AND SOUTHEAST
OKLAHOMA INCLUDING WESTERN NORTH TEXAS.  FARTHER NORTH DROUGHT
DEVELOPED...AND DROUGHT WORSENED ACROSS SOUTHEAST PARTS OF THE
SOONER STATE.

THE TABLE BELOW LIST THE AVERAGE PRECIPITATION FOR SEVERAL CLIMATE
DIVISIONS ACROSS THE WESTERN TWO-THIRDS OF OKLAHOMA SINCE 1 OCTOBER
2016...ENDING 28 JANUARY...2017.

PRECIPITATION/TEMPERATURE OUTLOOK...

THE 6 TO 10 DAY OUTLOOK (FEBRUARY 5 - 9) AND 8 TO 14 DAY OUTLOOK
(FEBRUARY 7 -13) FROM THE CLIMATE PREDICTION CENTER...INDICATE MUCH
BETTER CHANCES OF ABOVE NORMAL TEMPERATURES ACROSS OKLAHOMA AND
WESTERN NORTH TEXAS.  THE PRECIPITATION OUTLOOK IS FOR BETTER
CHANCES OF BELOW AVERAGE PRECIPITATION.

THE THREE MONTH OUTLOOK (FEBRUARY - APRIL) CALLS FOR BETTER CHANCES
OF ABOVE NORMAL TEMPERATURES WITH EQUAL CHANCES OF BELOW, NORMAL OR
ABOVE AVERAGE PRECIPITATION.



SUMMARY OF IMPACTS...

FIRE IMPACTS.
WITH DORMANT VEGETATION AND DROUGHT CONDITIONS...THE RISK OF
WILDLAND FIRES WILL CONTINUE TO INCREASE. THIS WILL BE ESPECIALLY
TRUE ON WARM...WINDY AND DRY DAYS.


AGRICULTURE.
ACCORDING TO THE USDA...APPROXIMATELY 25 PERCENT OF THE OKLAHOMA
WINTER WHEAT ACREAGE AND 24 PERCENT OF THE PASTURE ACREAGE WAS
RATED POOR/VERY POOR FOR THE MONTH OF DECEMBER.


HYDROLOGIC SUMMARY AND OUTLOOK...

DRIER THAN NORMAL CONDITIONS IN THE REGION SINCE THE SUMMER OF 2016
HAD CAUSED HYDROLOGICAL CONDITIONS TO DETERIORATE THROUGH EARLY
JANUARY 2017. HOWEVER... PRECIPITATION TOTALS OF 1.5 TO 3.5 INCHES
RECEIVED FROM A SLOW-MOVING STORM SYSTEM DURING THE MIDDLE OF
JANUARY HELPED IMPROVE CONDITIONS SLIGHTLY IN SOME AREAS.

INFORMATION FROM THE U.S. GEOLOGICAL SURVEY (USGS) INDICATED THAT
MOST LOCATIONS ALONG RIVERS AND CREEKS IN THE WESTERN TWO-THIRDS OF
OKLAHOMA...AND WESTERN NORTH TEXAS...WERE EXHIBITING 7-DAY
STREAMFLOW AVERAGES THAT WERE IN THE 25 TO 75 PERCENT (NORMAL)
RANGE. A FEW SCATTERED SITES HAD 7-DAY STREAMFLOW AVERAGES IN THE 10
TO 24 PERCENT (BELOW NORMAL) RANGE OR IN THE LESS THAN 10 PERCENT
(WELL BELOW NORMAL) RANGE.

WITH RESPECT TO HYDROLOGIC DROUGHT CONDITIONS... MODERATE DROUGHT
CONDITIONS WERE OCCURRING IN THE LOWER NORTH CANADIAN RIVER BASIN IN
CENTRAL OKLAHOMA. MODERATE DROUGHT CONDITIONS WERE ALSO OCCURRING IN
SEVERAL SMALL BASINS IN WESTERN OKLAHOMA... AS WELL AS THE WICHITA
RIVER BASIN IN WESTERN NORTH TEXAS.

RESERVOIR CONDITIONS AS OF JANUARY 29TH...

ACCORDING TO THE U.S. ARMY CORPS OF ENGINEERS (COE)... AS WELL AS
DATA FROM OTHER FEDERAL AND STATE AGENCIES... LEVELS AND STORAGE
CONTENTS AT MOST RESERVOIRS IN MOST OF THE REGION RANGED FROM
SLIGHTLY BELOW TO SLIGHTLY ABOVE NORMAL. HOWEVER...POOL ELEVATIONS
AND STORAGE CONTENTS AT SOME RESERVOIRS IN WESTERN AND SOUTHERN
OKLAHOMA AND WESTERN NORTH TEXAS... WERE BELOW NORMAL DUE TO THE
DROUGHT CONDITIONS. THE AFFECTED RESERVOIRS RANGED FROM ABOUT 1 TO
10 FEET BELOW THEIR NORMAL POOLS... OR ABOUT 10 TO 38 PERCENT BELOW
THEIR NORMAL STORAGE CAPACITIES. BELOW IS A LIST OF MAJOR RESERVOIRS
WITH THE NORMAL POOL AND CURRENT POOL ELEVATIONS... AND THE PERCENT
OF NORMAL VALUES.
