DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE SHREVEPORT LA
1155 PM CST FRI MAR 2 2018

...EXCESSIVE HEAVY RAINFALL DURING THE FINAL TWO WEEKS OF FEBRUARY
HAS ELIMINATED DROUGHT CONDITIONS ACROSS THE ARK-LA-TEX...

SYNOPSIS...

THE LATTER HALF OF JANUARY AND THE FIRST HALF OF FEBRUARY RECORDED
NEAR TO ABOVE NORMAL TEMPERATURES AND MUCH BELOW NORMAL RAINFALL AREAWIDE,
WHICH MAINTAINED DROUGHT CONDITIONS IN PLACE ACROSS MUCH OF THE ARK-LA-TEX.
HOWEVER, THE UPPER LEVEL PATTERN TOOK A SIGNIFICANT CHANGE BY MID-FEBRUARY
WITH AN UPPER LEVEL TROUGH ALONG THE WEST COAST, WITH A BROAD AREA OF
SOUTHWESTERLY FLOW ALOFT TRANSPORTING PACIFIC MOISTURE NORTHEAST ACROSS
THE SOUTHERN PLAINS, MISSISSIPPI, TENNESSEE, AND OHIO VALLIES. VERY
ABNORMALLY WARM AND HUMID AIR SURGED NORTH ACROSS THE SOUTHERN PLAINS AND
INTO THE OZARKS, SETTING THE STAGE FOR PROLONGED PERIODS OF SHOWERS AND
THUNDERSTORMS, SOME OF WHICH CONTAINED LOCALLY HEAVY RAINFALL, DURING THE
FINAL TWO WEEKS OF FEBRUARY. WIDESPREAD RAINFALL AMOUNTS OF SEVEN TO
TWELVE INCHES FELL AREAWIDE, WITH ISOLATED HIGHER AMOUNTS OF FIFTEEN TO
EIGHTEEN INCHES RECORDED ACROSS EXTREME SOUTHEAST OKLAHOMA AND PORTIONS OF
SOUTHWEST ARKANSAS. IN FACT, THE NATIONAL WEATHER SERVICE COOPERATIVE
OBSERVING STATION IN BROKEN BOW OKLAHOMA SET AN OKLAHOMA STATEWIDE
FEBRUARY RAINFALL RECORD AFTER RECORDING 18.14 INCHES OF RAIN FOR THE
MONTH, SHATTERING THE OLD MONTHLY STATEWIDE RECORD OF 13.21 INCHES SET
IN 1945 IN TUSKAHOMA, OKLAHOMA. THESE EXCESSIVE RAINFALL AMOUNTS RESULTED
IN PERIODS OF FLASH FLOODING OVER MUCH OF THE REGION, WHICH ALSO RESULTED
IN WIDESPREAD FLOODING OF AREA WATERWAYS. SINCE THE AREA LAKES AND
RESERVOIRS HAVE BEEN REPLENISHED, AND SOILS REMAIN COMPLETELY SATURATED,
DROUGHT CONDITIONS HAVE FINALLY ENDED ACROSS ALL OF THE ARK-LA-TEX FOR
THE FIRST TIME SINCE THE INITIAL DROUGHT DEVELOPED BACK DURING SEPTEMBER
2017.


SUMMARY OF IMPACTS...

AGRICULTURAL IMPACTS.
EXCESSIVE RAINFALL DURING THE LATTER HALF OF FEBRUARY HAS RESULTED IN
A RETURN TO ABOVE NORMAL SOIL MOISTURE AREAWIDE. THIS HAS LED TO
EITHER SATURATED OR FLOODED PASTURES, WHICH WERE TOO WET TO WORK OR
PLANT.

FIRE DANGER IMPACTS.
NO BURN BANS ARE IN EFFECT ACROSS THE FOUR STATE REGION. FIRE DANGER IS
EXPECTED TO REMAIN LOW THROUGH AT LEAST MID-MARCH.

CURRENT WATER RESTRICTIONS.
VOLUNTARY WATER RESTRICTIONS ARE IN EFFECT FOR SMALLER RURAL WATER
SYSTEMS ACROSS EAST TEXAS. NO OTHER KNOWN WATER RESTRICTIONS ARE IN EFFECT
AT THIS TIME.


CLIMATE SUMMARY...
MUCH ABOVE NORMAL RAINFALL FELL ACROSS ALL OF THE REGION DURING FEBRUARY,
ESPECIALLY DURING THE LAST TWO WEEKS OF THE MONTH. BELOW IS A LIST

IDABEL                     41.8              -0.9


PRECIPITATION/TEMPERATURE OUTLOOK...
DRY CONDITIONS WITH NEAR NORMAL TEMPERATURES WILL CONTINUE SATURDAY,
ALTHOUGH SCATTERED SHOWERS AND A FEW THUNDERSTORMS WILL RETURN TO MUCH
OF THE REGION SUNDAY AND MONDAY, AS LOW LEVEL MOISTURE INCREASES WITH THE
PASSAGE OF A COUPLE OF UPPER LEVEL DISTURBANCES. RAINFALL AMOUNTS OF A
HALF INCH TO AN INCH WILL BE POSSIBLE AREAWIDE THROUGH MONDAY, BEFORE A
COLD FRONT SWEEPS THROUGH THE REGION MONDAY AFTERNOON AND EVENING. A
RETURN OF BELOW NORMAL TEMPERATURES ARE EXPECTED TUESDAY THROUGH FRIDAY,
BEFORE TEMPERATURES BEGIN TO MODERATE BY NEXT WEEKEND, ALONG WITH THE
A POTENTIAL RETURN FOR RAIN.

THE THREE MONTH TEMPERATURE AND PRECIPITATION OUTLOOK FOR MARCH-APRIL-MAY,
ISSUED BY THE CLIMATE PREDICTION CENTER (CPC), INDICATES ABOVE NORMAL
PROBABILITIES FOR ABOVE NORMAL TEMPERATURES AREAWIDE, WITH EQUAL CHANCES
FOR SEEING EITHER BELOW NORMAL, NEAR NORMAL, OR ABOVE NORMAL RAINFALL
AREAWIDE OVER SOUTHEAST OKLAHOMA AND SOUTHWEST ARKANSAS. HOWEVER,
PROBABILITIES ARE SLIGHTLY ABOVE NORMAL FOR SEEING BELOW NORMAL RAINFALL
THROUGH MAY ACROSS EAST TEXAS AND NORTH LOUISIANA.


HYDROLOGIC SUMMARY AND OUTLOOK...
ALL OF THE AREA LAKES AND RESERVOIRS HAVE FULLY RECOVERED TO NEAR OR
WELL ABOVE CONSERVATION POOL STAGE IN WAKE OF THE EXCESSIVE RAINS OBSERVED
DURING THE LATTER HALF OF FEBRUARY. IN FACT, MANY RIVERS AND TRIBUTARIES
ACROSS THE RED, SULPHUR, SABINE, NECHES, AND OUACHITA RIVER BASINS REMAIN
IN MINOR TO MODERATE FLOODING, WITH LITTLE CHANGE TO VERY SLOW FALLS
EXPECTED THROUGH AT LEAST MID TO LATE MARCH GIVEN THE ADDITIONAL
RESERVOIR RELEASES FROM SEVERAL AREA RESERVOIRS.


NEXT ISSUANCE DATE...

SINCE THE DROUGHT OF 2017-18 HAS ENDED, THIS WILL BE THE FINAL DROUGHT
INFORMATION STATEMENT ISSUED, UNLESS SEVERE DROUGHT REDEVELOPS AT A
LATER TIME.
