DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE TULSA OK
201 PM CDT FRI JUL 25 2014

...RECENT RAINFALL AND MILD WEATHER DIMINISH DROUGHT CONDITIONS...

SYNOPSIS...

REASONABLE RAINFALL AND BELOW NORMAL TEMPERATURES IN MID JULY HAVE
HELPED DIMINISH DROUGHT CONDITIONS ACROSS MOST OF EASTERN
OKLAHOMA AND NORTHWEST ARKANSAS. HOWEVER...MORE RAINFALL IS STILL
NEEDED OVER MUCH OF EASTERN OKLAHOMA AND NORTHWEST ARKANSAS...
ESPECIALLY FOR OSAGE...PAWNEE AND CREEK COUNTIES.

SUMMARY OF IMPACTS...
ACCORDING TO THE U.S. DROUGHT MONITOR /USDA/ VALID 25 JULY
2014...

EXTREME DROUGHT /D3/ CONDITIONS REMAINED ACROSS SOUTHWEST OSAGE
COUNTY...MOST OF PAWNEE COUNTY...AND WESTERN CREEK COUNTIES.

IN ADDITION...SEVERE DROUGHT /D2/ EXTENDED SOUTHEAST TO COVER MOST OF
THE AREA ALONG AND NORTHWEST OF A LINE FROM VINITA TO TULSA TO
OKEMAH.

AND...MODERATE DROUGHT /D1/ REACHED FURTHER SOUTHEAST TO COVER THE
AREA ALONG AND NORTHWEST OF A LINE FROM ABOUT GROVE TO PRYOR TO
HENRYETTA. ANOTHER SMALL AREA OF D1 DROUGHT COVERED THE SOUTHWEST
PORTION OF CHOCTAW COUNTY. THE REMAINDER OF EASTERN OKLAHOMA AND
NORTHWEST ARKANSAS WERE CONSIDERED EITHER ABNORMALLY DRY OR NEAR
NORMAL FOR THIS TIME OF YEAR.

THE USDA IS A COLLABORATIVE EFFORT BETWEEN SEVERAL GOVERNMENT AND
ACADEMIC PARTNERS. IT IS A WEEKLY NATIONAL PRODUCT ISSUED ON
THURSDAY MORNING USING DATA COLLECTED THROUGH THE PRECIOUS TUESDAY
MORNING...SO IT DOES NOT CONSIDER PRECIPITATION WHICH HAS FALLEN
AFTER THE DATA CUT-OFF TIME.

THERE ARE FIVE LEVELS OF INTENSITY DEPICTED ON THE U.S. DROUGHT
MONITOR. THE USDM LEVELS ARE THE FOLLOWING...
D0 - ABNORMALLY DRY /NOT IN DROUGHT BUT SHOWING DRYNESS/
D1 - MODERATE DROUGHT
D2 - SEVERE DROUGHT
D3 - EXTREME DROUGHT
D4 - EXCEPTIONAL DROUGHT

THE LOCAL DROUGHT INFORMATION STATEMENT IS ISSUED BY THE NWS
OFFICE IN TULSA WHEN NEEDED TO SUPPLEMENT THE NATIONAL USDM
PRODUCT. LOCAL STATEMENTS MAY BE ISSUED BI-WEEKLY DURING TIMES
WHEN THE USDM INDICATES SEVERE DROUGHT CONDITIONS OR AS LOCAL
CONDITIONS WARRANT.

SUMMARY OF IMPACTS...
THE OKLAHOMA STATE CLIMATE OFFICE /OKLAHOMA CLIMATOLOGICAL
SURVEY...OCS/ IS HOSTING RECORDED UPDATE FOCUSED ON THE CURRENT
CONDITIONS...IMPACTS...AND OUTLOOKS FOR THE ONGOING DROUGHT ACROSS
THE SOUTHERN PLAINS. UPDATED DROUGHT BRIEFINGS ARE AVAILABLE ABOUT
EVERY TWO WEEKS AT WWW.YOUTUBE.COM/USER/SCIPP01.

SOIL MOISTURE IMPACTS...
FOR 25 JULY 2014...THE OKLAHOMA CLIMATOLOGICAL SURVEY /OCS/ THE
DAILY AVERAGED FRACTIONAL WATER INDEX AT 10 INCHES WAS GENERALLY
70 TO 90 PERCENT. DRIER AREAS OF LESS THAN 50 PERCENT EXISTED IN
OKFUSKEE...OKMULGEE AND MCINTOSH COUNTIES. DRY CONDITIONS ALSO
EXISTED ACROSS OTTAWA...DELAWARE...AND MAYES COUNTIES.

THE ARKANSAS-RED BASIN RIVER FORECAST CENTER INDICATED THE SOIL
MOISTURE AT 50 TO 70 PERCENT OF NORMAL OVER A LARGE PORTION OF
EASTERN OKLAHOMA AND NORTHWEST ARKANSAS. AREAS WITH LESS THAN 50
PERCENT OF NORMAL SOIL MOISTURE WERE SCATTERED MAINLY OVER
NORTHEAST OKLAHOMA.

AS OF 25 JULY 2014...THE CLIMATE PREDICTION CENTER /CPC/ ALSO
INDICATED SOIL MOISTURE WAS DEFICIENT MAINLY ACROSS NORTHEAST
OKLAHOMA AND FAR NORTHWEST ARKANSAS.

FIRE IMPACTS...
NO BURN BANS WERE IN EFFECT FOR EASTERN OKLAHOMA AND NORTHWEST
ARKANSAS.

AGRICULTURAL IMPACTS...
LOW POND LEVELS ARE STILL COMMON IN THE AREAS OF EXTREME AND SEVERE
DROUGHT...MAINLY IN NORTHEAST OKLAHOMA. PASTURES HAVE RESPONDED
WELL TO RECENT RAINS AND FORAGE LEVELS HAVE IMPROVED.

CLIMATE SUMMARY...
IN THE SHORT TERM...OVER THE LAST 14 DAYS ENDING 25 JULY...
SIGNIFICANT RAINS OCCURRED OVER MUCH OF THE AREA. GENERALLY 1 TO 2
INCHES OF RAIN FELL ALONG AND SOUTHWEST OF A LINE FROM PONCA CITY
TO FORT SMITH. OVER 3 INCHES OF RAIN FELL IN PORTIONS OF
PUSHMATAHA AND CHOCTAW COUNTIES. UNFORTUNATELY...NORTHEAST
OKLAHOMA AND NORTHWEST ARKANSAS RECEIVED AROUND AN INCH OR LESS.

OVER THE LAST 30 DAYS...MOST AREAS HAVE RECEIVED BETWEEN 2 AND 5
INCHES OF RAIN. SOUTHEAST OKLAHOMA RECEIVED EVEN MORE...WITH
WIDESPREAD 5 TO 7 INCHES OF RAIN. THERE IS ANOTHER NARROW STRIP OF
4 TO 5 INCHES OF RAIN OVER PORTIONS OF PAWNEE...OSAGE...
TULSA...AND SOUTHERN ROGERS COUNTIES.

IN THE LONGER TERM...SINCE THE BEGINNING OF THE WATER YEAR STARTING
IN OCTOBER 2013...RAINFALL TOTALS HAVE RANGED FROM 15 TO NEARLY 40
INCHES...WITH THE HIGHEST AMOUNTS IN SOUTHEAST OKLAHOMA AND WEST
CENTRAL ARKANSAS. THIS INDICATES THE GREATEST DEFICITS OF 8 TO 16
INCHES ALONG AND NORTH OF INTERSTATE 40.

PRECIPITATION/TEMPERATURE OUTLOOK...

THROUGH FRIDAY AUGUST 1...NOT MUCH SIGNIFICANT RAIN IS EXPECTED
EXCEPT OVER FAR SOUTHEAST OKLAHOMA WHERE A HALF TO ONE INCH
AVERAGE WILL BE POSSIBLE. OTHERWISE...AVERAGE RAINFALL SHOULD BE
UNDER A QUARTER INCH. OF COURSE...THIS TIME OF YEAR ANY
THUNDERSTORM COULD PRODUCE LOCALIZED HEAVY RAINFALL.

THE CLIMATE PREDICTION CENTER /CPC/ OUTLOOK CALLS FOR BELOW
NORMAL TEMPERATURES FOR ALL OF THE SOUTHERN UNITED STATES FOR THE
FIRST WEEK OF AUGUST. THERE WILL BE ABOVE NORMAL CHANCES OF
PRECIPITATION FOR SOUTHEAST OKLAHOMA...WITH NEAR NORMAL CHANCES IN
NORTHEAST OKLAHOMA AND NORTHWEST ARKANSAS.

THE CPC ONE MONTH OUTLOOK FOR AUGUST INDICATES ENHANCED CHANCES
THAT TEMPERATURES WILL BE ABOVE NORMAL FOR EASTERN OKLAHOMA AND
NORTHWEST ARKANSAS. PRECIPITATION CHANCES ARE EXPECTED TO BE NEAR
NORMAL.

THE CPC SEASONAL DROUGHT OUTLOOK VALID 17 JULY 2014 THROUGH 31
OCTOBER 2014 INDICATES THAT DROUGHT CONDITIONS ARE EXPECTED TO
IMPROVE ACROSS THE AREA.

HYDROLOGIC SUMMARY AND OUTLOOK...
ACCORDING TO THE U.S. ARMY CORPS OF ENGINEERS /COE/...MOST OF THE
MAJOR RESERVOIRS IN EASTERN OKLAHOMA AND NORTHWEST ARKANSAS WERE
REPORTING NORMAL POOL LEVELS WITHIN FLOOD CONTROL STORAGE. ONLY
ONE RESERVOIR REMAINED WITH CONSERVATION POOLS BELOW NORMAL AS OF
25 JULY 2014...SKIATOOK LAKE AT 64 PERCENT. BIRCH LAKE WAS UP TO
94 PERCENT FULL.

ACCORDING TO THE U.S. GEOLOGICAL SURVEY /USGS/...AS OF 25 JULY
2014...MOST OF THE REPORTING GAGES ACROSS EASTERN OKLAHOMA AND
NORTHWEST ARKANSAS WERE REPORTING NEAR NORMAL STREAM-FLOW LEVELS
FOR THIS TIME OF YEAR. A FEW STREAMS WERE RUNNING BELOW NORMAL...
INCLUDING FLINT CREEK...SPRING RIVER...LEE CREEK AND BIRD CREEK.

NEXT ISSUANCE DATE...
THIS PRODUCT WILL BE UPDATED ON OR ABOUT SEPTEMBER 4...OR SOONER
IF SIGNIFICANT CHANGES IN DROUGHT CONDITIONS OCCUR.
