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

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.

PROBABILITIES FOR ABOVE NORMAL TEMPERATURES AREAWIDE, WITH EQUAL CHANCES  
FOR SEEING EITHER BELOW NORMAL, NEAR NORMAL, OR ABOVE NORMAL RAINFALL

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...
