DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE SHREVEPORT LA
1110 PM CDT SAT JUN 8 2013
...RECENT HEAVY RAINFALL HAS YIELDED SOME ADDITIONAL IMPROVEMENT TO
DROUGHT CONDITIONS ACROSS SOUTHEAST OKLAHOMA...SOUTHWEST ARKANSAS...
AND PORTIONS OF NORTHEAST TEXAS...
SYNOPSIS...
BELOW NORMAL RAINFALL WAS OBSERVED ACROSS MUCH OF THE REGION DURING MAY...
WITH THE HEAVIER RAINFALL HAVING FALLEN FARTHER NORTH ACROSS CENTRAL
AND EASTERN OKLAHOMA INTO CENTRAL ARKANSAS. NEAR TO SLIGHTLY BELOW NORMAL
TEMPERATURES WERE OBSERVED OVER MUCH OF THE REGION DURING MAY...WITH
SLIGHTLY ABOVE NORMAL TEMPERATURES NOTED OVER EAST TEXAS. HOWEVER...TWO
SEPARATE WEATHER SYSTEMS MOVED THROUGH THE REGION DURING THE FIRST WEEK
OF JUNE...WITH THE LATTER RESULTING IN EXTENSIVE AREAS OF ABOVE NORMAL
RAINFALL OVER DEEP EAST TEXAS...MUCH OF NORTH LOUISIANA...SOUTHWEST
ARKANSAS...AND PORTIONS OF EXTREME NORTHEAST TEXAS ALONG AND NORTH OF THE
INTERSTATE 30 CORRIDOR. THIS RECENT RAINFALL HAS REPLENISHED SOIL
MOISTURE ACROSS MUCH OF THE REGION...ESPECIALLY OVER SOME OF THE MODERATE
DROUGHT STRICKEN AREAS OF EXTREME NORTHEAST TEXAS. RAINFALL TOTALS OVER
THE LAST FIVE WEEKS (SINCE EARLY MAY) HAVE RANGED FROM FOUR TO SIX INCHES
OVER MUCH OF THE REGION...WITH AMOUNTS IN EXCESS OF EIGHT INCHES OVER
NORTHERN MCCURTAIN COUNTY OKLAHOMA AS WELL AS NORTHERN HOWARD COUNTY
ARKANSAS. THIS HAS RESULTED IN NEAR NORMAL RAINFALL FOR THE PERIOD OVER
PORTIONS OF EAST TEXAS...WITH SLIGHT SURPLUSES ELSEWHERE ACROSS THE REGION.
THE NEAR TO ABOVE NORMAL RAINFALL OBSERVED SINCE EARLY MAY HAS ELIMINATED
DROUGHT CONDITIONS OVER SOUTHEAST OKLAHOMA AND MUCH OF SOUTHWEST ARKANSAS.
DROUGHT CONDITIONS HAVE ALSO BEEN ALLEVIATED ACROSS MILLER COUNTY ARKANSAS
AS WELL AS PORTIONS OF NORTHWEST LOUISIANA SOUTH OF A SHREVEPORT...TO
COUSHATTA AND GOLDONNA LINE. HOWEVER...MODERATE CONDITIONS (D1) PERSIST
ACROSS MUCH OF NORTHEAST TEXAS IN A 70 MILE WIDE AREA SOUTH OF A LINE FROM
MOUNT VERNON...TO MOUNT PLEASANT...AND LINDEN LINE...AS WELL AS A SMALL
PORTION OF SOUTHWEST ARKANSAS AND NORTHWEST LOUISIANA ACROSS SOUTHERN
LAFAYETTE AND COLUMBIA COUNTIES...AS WELL AS NORTHERN CADDO...BOSSIER...AND
WEBSTER PARISHES. ABNORMALLY DRY (D0) CONDITIONS EXIST SURROUNDING THE
MODERATE DROUGHT AREAS...AND ENCOMPASS THE HIGHWAY 82 CORRIDOR ACROSS
RED RIVER AND BOWIE COUNTIES IN NORTHEAST TEXAS INTO MILLER...NORTHERN
LAFAYETTE AND COLUMBIA...AND UNION COUNTIES IN SOUTHWEST ARKANSAS.
ABNORMALLY DRY CONDITIONS ALSO REMAIN ACROSS SOUTHERN CADDO...BOSSIER...
WEBSTER...AND ALL OF BIENVILLE...CLAIBORNE...AND WESTERN LINCOLN PARISHES
IN NORTHWEST LOUISIANA.
SUMMARY OF IMPACTS...
AGRICULTURAL IMPACTS.
DESPITE A DRIER THAN NORMAL MAY ACROSS MUCH OF THE REGION...RECENT HEAVY
RAINFALL HAS RESULTED IN TOPSOIL MOISTURE IMPROVEMENT OVER MOST AREAS.
THE AREA CORN AND WHEAT CROP ARE IN GOOD SHAPE...WITH HAY HARVESTING
UNDERWAY. RUNOFF HAS ALLOWED FOR MOST LIVESTOCK PONDS TO FILL TO CAPACITY.
FIRE DANGER IMPACTS.
NO BURN BANS ARE IN EFFECT AT THIS TIME.
CURRENT WATER RESTRICTIONS.
AQUIFER LEVELS REMAIN ABNORMALLY LOW ACROSS MUCH OF THE REGION. CITIES IN
NORTHEAST TEXAS THAT REMAIN UNDER A VOLUNTARY OR A MILD RATIONING OF WATER
UNTIL FURTHER NOTICE INCLUDE: PITTSBURG...GLADEWATER...WHITE OAK...
MARSHALL...HALLSVILLE...TYLER...NACOGDOCHES...MELROSE...SAN AUGUSTINE...
CENTER...HEMPHILL...BULLARD...GILMER...HAWKINS...AND HUNTINGTON. OTHER
SMALLER WATER SYSTEMS ACROSS EAST TEXAS ALSO REMAIN UNDER VOLUNTARY OR A
MILD RATIONING OF WATER UNTIL FURTHER NOTICE.

PRECIPITATION/TEMPERATURE OUTLOOK...
AN UPPER LEVEL DISTURBANCE WILL SHIFT SOUTHEAST ACROSS THE PLAINS
AND INTO THE MISSISSIPPI VALLEY SUNDAY...WITH SHOWERS AND
THUNDERSTORMS OVER OKLAHOMA SUNDAY MORNING EXPECTED TO WEAKEN AS
THEY MOVE INTO SOUTHEAST OKLAHOMA...EXTREME NORTHEAST TEXAS...AND
SOUTHWEST ARKANSAS AROUND OR SHORTLY AFTER SUNRISE.
HOWEVER...SURFACE BOUNDARIES FROM THESE SHOWERS AND THUNDERSTORMS
WILL LIKELY FOCUS ADDITIONAL SHOWER AND THUNDERSTORM DEVELOPMENT
LATE SUNDAY MORNING THROUGH THE AFTERNOON AND EARLY EVENING AS THE
PARENT UPPER LEVEL DISTURBANCE MOVES OVERHEAD DURING PEAK HEATING.
RAINFALL AMOUNTS OF A TENTH TO A QUARTER OF AN INCH IS EXPECTED
ACROSS PORTIONS OF EXTREME NORTHEAST TEXAS AND NORTH
LOUISIANA...WITH AMOUNTS OF A QUARTER TO A HALF INCH POSSIBLE ACROSS
SOUTHEAST OKLAHOMA AND SOUTHWEST ARKANSAS. FOLLOWING THE PASSAGE OF
THIS UPPER LEVEL DISTURBANCE SUNDAY NIGHT...AN UPPER LEVEL RIDGE
WILL BUILD EAST ACROSS THE SOUTHERN PLAINS INTO THE MISSISSIPPI
VALLEY MONDAY AND TUESDAY...AND REMAIN DOMINANT OVER THE REGION
THROUGH THE NEXT TEN DAYS. THUS...ABOVE NORMAL TEMPERATURES /MOSTLY
IN THE MID 90S/ AND NO RAINFALL IS EXPECTED AFTER SUNDAY...WHICH
WILL RESULT IN A DRYING OF SOIL MOISTURE FROM AMPLE RAIN MUCH OF THE
REGION HAS OBSERVED SINCE THE FIRST OF JUNE.
THE THREE MONTH TEMPERATURE OUTLOOK FOR JUNE-JULY-AUGUST...ISSUED BY THE
CLIMATE PREDICTION CENTER (CPC)...INDICATES HIGHER PROBABILITIES FOR
ABOVE NORMAL TEMPERATURES FOR THE ENTIRE REGION. THE THREE MONTH
PRECIPITATION OUTLOOK THROUGH AUGUST DOES INDICATE EQUAL CHANCES FOR
SEEING BELOW NORMAL...NORMAL...AND ABOVE NORMAL RAINFALL OVER MUCH
OF THE REGION. AT THIS TIME...NEAR NEUTRAL CONDITIONS IN THE
EQUATORIAL PACIFIC OCEAN ARE EXPECTED TO CONTINUE THROUGHOUT THIS
SUMMER...RESULTING IN VERY LITTLE SKILL IN FORECASTING CERTAIN
PRECIPITATION PATTERNS OVER THE AREA.
HYDROLOGIC SUMMARY AND OUTLOOK...
MUCH ABOVE NORMAL RAINFALL FELL ACROSS THE MIDDLE RED RIVER BASIN OF
SOUTHERN OKLAHOMA DURING MID AND LATE MAY...WHICH HAS RESULTED IN
HIGHER THAN NORMAL STREAMFLOW ACROSS THE LOWER RED RIVER BASIN
ACROSS NORTHWEST LOUISIANA. THIS HAS RESULTED IN THE CLOSURE OF
PUBLIC BOAT LAUNCHES ALONG THE RED RIVER IN SHREVEPORT AND BOSSIER
CITY UNTIL FURTHER NOTICE...WHEN STREAMFLOW IS REDUCED. MOST AREA
LAKES AND WATERWAYS REMAIN NEAR OR ABOVE NORMAL POOL STAGE ACROSS
SOUTHEAST OKLAHOMA...SOUTHWEST ARKANSAS...AND NORTH
LOUISIANA...ALTHOUGH DEFICITS CONTINUE ACROSS THE CYPRESS AND MIDDLE
SABINE BASINS...WHERE POOL STAGES AT LAKE FORK...BOB SANDLIN AND
LAKE OF THE PINES REMAIN SOME THREE TO FIVE FEET BELOW NORMAL. SOME
SLIGHT DEFICIENCY CONTINUES ACROSS THE NECHES BASIN AS WELL...AS SAM
RAYBURN RESERVOIR HAS FALLEN TO NEARLY TWO FEET BELOW NORMAL.
ADDITIONAL SLOW DETERIORATION IS EXPECTED THROUGHOUT JUNE AS
INCREASING TEMPERATURES WILL YIELD HIGHER EVAPORATION RATES...AND
LITTLE TO NO RAINFALL IS EXPECTED.
NEXT ISSUANCE DATE...
THE NEXT DROUGHT INFORMATION STATEMENT WILL BE ISSUED BY LATE JUNE.
