DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE TULSA OK
1138 AM CDT FRI JUN 7 2013

...DROUGHT IMPACTS EASE ACROSS EASTERN OKLAHOMA...

SYNOPSIS...

RECENT HEAVY RAINFALL HAS HELPED TO EASE THE DROUGHT CONDITIONS
ACROSS EASTERN OKLAHOMA. ONLY MODERATE /D1/ DROUGHT AND ABNORMALLY
DRY /D0/ CONDITIONS REMAIN OVER A PORTION OF NORTHEAST OKLAHOMA.
THEREFORE...THIS WILL BE THE FINAL DROUGHT INFORMATION STATEMENT
UNTIL SEVERE /D2/ DROUGHT CONDITIONS RETURN TO EASTERN OKLAHOMA OR
NORTHWEST ARKANSAS. THIS LAST STATEMENT WILL FOCUS ONLY ON THE CURRENT
AREA WITH D1 CONDITIONS.

ACCORDING TO THE U.S. DROUGHT MONITOR /USDM/ VALID 4 JUNE
2013...MODERATE /D1/ DROUGHT CONDITIONS WERE PRESENT OVER
OSAGE...PAWNEE...WASHINGTON...AND NORTHWEST NOWATA COUNTIES IN
EASTERN OKLAHOMA.

ABNORMALLY DRY /D0/ CONDITIONS EXIST OVER AREAS OF NORTHERN
CREEK...TULSA...MAYES...AND SOUTHEAST NOWATA COUNTIES IN EASTERN
OKLAHOMA.

THE USDM 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 PREVIOUS 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...

STATE AND LOCAL ACTIONS.
THE OKLAHOMA STATE CLIMATE OFFICE /OKLAHOMA CLIMATOLOGICAL SURVEY/
IS HOSTING RECORDED UPDATES FOCUSED ON THE CURRENT
CONDITIONS...IMPACTS...AND OUTLOOKS FOR THE ONGOING DROUGHT ACROSS
THE SOUTHERN PLAINS.

THE LONE CHIMNEY WATER ASSOCIATION...WHICH PROVIDES WATER TO THE
CITY OF PAWNEE...SEVERAL PAWNEE COUNTY RURAL WATER DISTRICTS...AND
IS A SECONDARY SOURCE FOR CLEVELAND...IS STILL CONCERNED ABOUT
RUNNING OUT OF WATER...AND CONSERVATION MEASURES ARE STILL NEEDED
DESPITE RECENT RAIN. RAINFALL OVER THE AREA DURING THE LAST 10
DAYS HAS HELPED TO INCREASE THE LAKE LEVEL. HOWEVER...THE LAKE
STILL REMAINS 9 FEET 3 INCHES BELOW NORMAL...WHICH IS UP FROM THE
12 FEET BELOW NORMAL PRIOR TO THE RAIN.

SOIL MOISTURE IMPACT.
THE OKLAHOMA CLIMATOLOGICAL SURVEY /OCS/ DAILY AVERAGED FRACTIONAL
WATER INDEX FOR 6 JUNE 2013 SHOWS VALUES OF 0.9 TO 1 ACROSS ALL OF
EASTERN OKLAHOMA /WHERE 1.0 IS SATURATED AND 0.0 IS COMPLETELY
DRY/ FOR 2...10...AND 24 INCHES BELOW THE GROUND.

AS OF 6 JUNE 2013...THE ARKANSAS-RED BASIN RIVER FORECAST CENTER
/ABRFC/ GRIDDED SOIL MOISTURE INDICATES THE UPPER ZONE IS 30
PERCENT OR MORE ACROSS THE D1 AREA...WHICH CORRESPONDS TO 110 TO
OVER 150 PERCENT OF NORMAL ACROSS THIS AREA. THE LOWER ZONE WAS
GENERALLY OVER 40 PERCENT FULL...WITH A FEW ISOLATED AREAS OF 20
TO 40 PERCENT FULL. THESE VALUES ARE 50 TO 100 PERCENT OF NORMAL FOR
MUCH OF PAWNEE AND ISOLATED PORTIONS OF THE OTHER COUNTIES IN D2.
THE REMAINDER OF THE D2 AREA IS 100 TO NEAR 150 PERCENT FULL.

THE CLIMATE PREDICTION CENTER /CPC/ SOIL MOISTURE ANOMALY ANALYSIS AS
OF 6 JUNE 2013 SHOWED NEAR NORMAL SOIL MOISTURE CONDITIONS IN THE
D2 REGION.

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


CLIMATE SUMMARY...

IN THE LAST 10 DAYS...LOCATIONS NORTHWEST OF I-44 HAVE RECEIVED
FROM AROUND 4 TO AROUND 9 INCHES OF RAIN. MOST OF THIS RAINFALL
OCCURRED ON MAY 29...WHEN THIS AREA RECORDED WIDESPREAD 3 TO 5
INCHES OF RAIN. ADDITIONAL THUNDERSTORM ACTIVITY BROUGHT
ADDITIONAL ROUNDS OF THE HEAVY RAIN AT THE END OF MAY AND INTO THE
BEGINNING OF JUNE.

IN THE LAST 30 DAYS ENDING 7 AM JUNE 7...RAINFALL TOTALS HAVE
RANGED FROM 5 TO 14 INCHES THROUGHOUT EASTERN OKLAHOMA AND
NORTHWEST ARKANSAS. THIS CORRESPONDS TO 100 TO AROUND 200 PERCENT
OF NORMAL ACROSS THE D2 AREA. MOST OF THE REMAINDER OF EASTERN
OKLAHOMA AND NORTHWEST ARKANSAS WAS ALSO ABOVE NORMAL FOR THIS TIME
PERIOD...THOUGH SOME AREAS OF NORTHEAST AND FAR SOUTHEAST OKLAHOMA
WERE BELOW NORMAL.

ACCORDING TO OCS...FOR THE LAST 30 DAYS ENDING 6 JUNE 2013...NORTHEAST
OKLAHOMA RANKS AS THE 9TH WETTEST PERIOD SINCE RECORDS BEGAN IN
1921. EAST CENTRAL OKLAHOMA RANKS AS THE 10TH WETTEST AND SOUTHEAST
OKLAHOMA RANKS AS THE 12TH WETTEST PERIOD. FOR THE WATER YEAR TO DATE
/OCTOBER 1-JUNE 6/...NORTHEAST OKLAHOMA RANKS AS THE 44TH DRIEST ON
RECORD...EAST CENTRAL OKLAHOMA RANKS AS THE 43RD DRIEST...AND
SOUTHEAST OKLAHOMA RANKS AS THE 27TH DRIEST. FOR THE PAST YEAR /7
JUNE 2012-6 JUNE 2013/...NORTHEAST OKLAHOMA RANKS AS THE 15TH
DRIEST ON RECORD...EAST CENTRAL OKLAHOMA RANKS AS THE 26TH
DRIEST...AND SOUTHEAST OKLAHOMA RANKS AS THE 20TH DRIEST.


PRECIPITATION/TEMPERATURE OUTLOOK...

NEAR TO ABOVE NORMAL TEMPERATURES ARE EXPECTED OVER THE NEXT 7
DAYS. THERE IS A CHANCE FOR SHOWERS AND THUNDERSTORMS ACROSS
NORTHEAST OKLAHOMA ON SUNDAY...WITH DRY CONDITIONS FORECAST FOR
THE REMAINDER OF THE NEXT 7 DAYS.

THE CLIMATE PREDICTION CENTER /CPC/ 8-14 DAY OUTLOOK CALLS FOR
AN ENHANCED CHANCE OF ABOVE NORMAL TEMPERATURES FOR ALL OF
EASTERN OKLAHOMA AND NORTHWEST ARKANSAS. THERE IS A SLIGHTLY
ENHANCED CHANCE FOR BELOW MEDIAN RAINFALL ACROSS EAST CENTRAL
AND SOUTHEAST OKLAHOMA...WITH NEAR NORMAL CHANCES ELSEWHERE.

BEYOND THIS PERIOD...THE CPC OUTLOOK FOR JUNE 2013 /ISSUED 31
MAY 2013/ INDICATES AN EQUAL CHANCE FOR ABOVE...NEAR...AND BELOW
NORMAL TEMPERATURES AND PRECIPITATION ACROSS EASTERN OKLAHOMA AND
NORTHWEST ARKANSAS.

THE CPC U.S. SEASONAL DROUGHT OUTLOOK VALID JUNE 6 THROUGH AUGUST
31 INDICATES DROUGHT CONDITIONS ARE LIKELY TO IMPROVE ACROSS THE
CURRENT SEVERE /D2/ DROUGHT 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 LEVELS WITHIN FLOOD CONTROL STORAGE. ONLY ONE RESERVOIR
REMAINED WITH A CONSERVATION POOL BELOW NORMAL AS OF 7 JUNE
2013...SKIATOOK LAKE AT 80 PERCENT.

ACCORDING TO THE U.S. GEOLOGICAL SURVEY /USGS/...7-DAY AVERAGE
STREAMFLOWS FOR ALL OF THE REPORTING STATIONS ACROSS EASTERN
OKLAHOMA AND NORTHWEST ARKANSAS WERE NEAR NORMAL TO WELL ABOVE
NORMAL FOR THIS TIME OF YEAR AS OF 6 JUNE 2013.


NEXT ISSUANCE DATE...

THIS WILL BE THE FINAL DROUGHT INFORMATION STATEMENT UNTIL SEVERE
/D2/ DROUGHT CONDITIONS RETURN TO EASTERN OKLAHOMA OR NORTHWEST
ARKANSAS.
