HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE SHREVEPORT LA
720 AM CDT SAT MAY 27 2006

...DROUGHT INFORMATION STATEMENT...

...DROUGHT CONDITIONS HAVE RETURNED TO MUCH OF THE FOUR STATE 
REGION...

MOST OF THE MONTH OF MAY HAS BEEN ATTRIBUTED TO ABOVE NORMAL 
TEMPERATURES AND MUCH BELOW NORMAL RAINFALL ACROSS THE FOUR STATE 
REGION...AS A PERSISTENT UPPER LEVEL RIDGE OF HIGH PRESSURE HAS 
REMAINED IN PLACE OVER THE SOUTHERN PLAINS/GULF COAST REGION DURING THE 
LAST TWO AND A HALF WEEKS. AVERAGE TEMPERATURES DURING THIS TIME HAVE 
REMAINED SOME FIVE TO SEVEN DEGREES ABOVE NORMAL, WHILE MONTHLY 
RAINFALL TOTALS HAVE RANGED FROM JUST A HALF AN INCH ACROSS PORTIONS OF 
NORTHEAST TEXAS (LONGVIEW)...TO AN INCH AND A QUARTER ACROSS DEEP EAST 
TEXAS (LUFKIN) AND PORTIONS OF NORTHWEST LOUISIANA (SHREVEPORT). 
RAINFALL TOTALS OF TWO TO TWO AND A HALF INCHES WERE COMMON ELSEWHERE 
ACROSS THE REMAINDER OF EAST TEXAS, SOUTHEAST OKLAHOMA, SOUTHWEST 
ARKANSAS, AND PORTIONS OF NORTHCENTRAL LOUISIANA, WITH THREE TO FOUR 
INCH AMOUNTS FOUND OVER THE EASTERN SECTIONS OF NORTHCENTRAL LOUISIANA. 
THESE TOTALS WERE SOME TWO TO FOUR INCHES BELOW NORMAL FOR THE MONTH, 
DURING A TIME WHERE MUCH OF THE SPRING RAINS FALL, AND NORMAL MONTHLY 
RAINFALL IS AT ITS HIGHEST. THE LACK OF RAINFALL IN THE LAST 12+ DAYS 
(AND IN SOME CASES OVER SOUTHEAST OKLAHOMA AND ADJACENT SOUTHWEST 
ARKANSAS, 16+ DAYS) HAS PROMPTED THE U.S. DROUGHT MONITOR TO RECLASSIFY 
THOSE AREAS WEST OF A NASHVILLE, ARKANSAS...TO MAGNOLIA...TO MINDEN, 
LOUISIANA...TO HEMPHILL, TEXAS LINE, TO MODERATE DROUGHT (D1) STATUS IN 
ITS MAY 23RD UPDATE. ABNORMALLY DRY CONDITIONS (D0) REMAIN ELSEWHERE 
ACROSS SOUTHCENTRAL ARKANSAS AND NORTHCENTRAL LOUISIANA. THE U.S. 
DROUGHT MONITOR IS UPDATED EVERY THURSDAY MORNING, AND CAN BE VIEWED AT:
HTTP://WWW.DROUGHT.UNL.EDU/DM/MONITOR.HTML. 

THE FOLLOWING ARE MAY RAINFALL TOTALS AND THEIR DEPARTURES, AS WELL 
AS THE YEAR TO DATE RAINFALL/DEPARTURES THROUGH MAY 26TH FOR 
SELECTED CITIES IN THE FOUR STATE REGION:

-----------------------------------------------------------------

HYDROLOGIC IMPACTS...

DESPITE THE LACK OF RAINFALL RECEIVED DURING MAY...AREA LAKES AND 
RESERVOIRS REMAIN NEAR THEIR RESPECTIVE CONSERVATION POOL STAGES. ON 
THE OTHER HAND...STREAMFLOWS AND STAGES ON RIVERS AND BAYOUS REMAIN 
BELOW NORMAL THROUGHOUT THIS MONTH. FORTUNATELY, THE HEAVY RAINFALL 
RECEIVED IN MID MARCH AND AGAIN IN LATE APRIL CONTINUES TO PROVIDE A 
CUSHION AGAINST WORSENING WATER SUPPLY CONDITIONS, AND HAS KEPT 
RESERVOIRS NEARLY STEADY.

FIRE DANGER IMPACTS...

NO BURN BANS ARE IN EFFECT ACROSS EXTREME SOUTHEAST 
OKLAHOMA...SOUTHERN ARKANSAS...NORTH LOUISIANA AND EASTERN TEXAS.

RESTRICTIONS...

NO WATER RESTRICTIONS IN EFFECT.

AGRICULTURAL IMPACTS...

NO SIGNIFICANT AGRICULTURAL CONCERNS ARE AVAILABLE AT THIS TIME. 
HOWEVER, SHOULD TIMELY RAINFALL NOT RETURN DURING THE LAST SEVERAL DAYS 
OF MAY OR THE FIRST WEEK OR TWO OF JUNE, IMPACTS WILL BE FELT 
AGRICULTURALLY, AS JUNE THROUGH SEPTEMBER ARE THE HOTTEST/DRIEST TIMES 
OF THE YEAR, WHERE VERY HIGH EVAPOTRANSPIRATION RATES OCCUR.

OUTLOOK...

NEAR NEUTRAL CONDITIONS ARE NOW PRESENT IN THE NINA 3.4 REGION OF THE 
PACIFIC OCEAN, WHICH BODES WELL FOR THE FOUR STATE REGION, AS EQUAL 
CHANCES FOR EQUAL CHANCES OF BELOW NORMAL, NORMAL, AND ABOVE NORMAL 
RAINFALL, AS NOTED IN THE SUMMER OUTLOOK ISSUED EARLIER THIS MONTH 
FROM THE CLIMATE PREDICTION CENTER. HOWEVER, ABOVE NORMAL PROBABILITIES 
FOR ABOVE NORMAL TEMPERATURES CAN BE EXPECTED ACROSS MUCH OF THE 
SOUTHERN PLAINS THROUGH AUGUST.
