DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE NORTH PLATTE NE
825 AM CDT THU MAY 16 2013
...NO CHANGE TO THE EXCEPTIONAL DROUGHT CONDITIONS ACROSS ALL OF
WESTERN AND NORTH CENTRAL NEBRASKA...
SYNOPSIS
THE WEATHER PATTERN FROM MID APRIL THROUGH MID MAY HAS REMAINED
ACTIVE ACROSS WESTERN AND NORTH CENTRAL NEBRASKA WHICH IS TYPICAL
FOR THIS TIME OF YEAR AS THE NORTHERN HEMISPHERE CONTINUES ITS
TRANSITION TO SUMMER. SEVERAL STORM SYSTEMS MOVED ACROSS THE PLAINS
IN THE LAST 30 DAYS AND ALLOWED FOR A FEW CHANCES FOR PRECIPITATION.
THE LAST PART OF APRIL INTO THE FIRST PART OF MAY CONTINUED TO BE
COOLER THAN AVERAGE HOWEVER...THEREFORE SOME OF THE PRECIPITATION
FELL IN THE FORM OF SNOW EVEN INTO THE FIRST OF MAY IN SOME PARTS OF
THE AREA. HOWEVER...AS WARMER AIR MOVED INTO THE AREA INTO MID
MAY...RAIN WAS THE DOMINATE PRECIPITATION TYPE. SOME AREAS WERE ABLE
TO SEE SIGNIFICANT RAINFALL THAT CAME WITH THUNDERSTORMS WHICH
PROVIDED LOCALIZED SHORT TERM DROUGHT RELIEF...THOUGH LONG TERM
SIGNIFICANT PRECIPITATION DEFICITS STILL REMAIN ACROSS ALL OF
WESTERN AND NORTH CENTRAL NEBRASKA.
LOCAL AREAS AFFECTED
AS OF MAY 16...ACCORDING TO THE US DROUGHT MONITOR...EXCEPTIONAL
DROUGHT CONDITIONS WERE PRESENT ACROSS
HOOKER...MCPHERSON...PERKINS...EASTERN KEITH...WESTERN LINCOLN AND
EASTERN ARTHUR COUNTIES. ELSEWHERE...EXTREME DROUGHT CONDITIONS WERE
PRESENT.

RIVER AND RESERVOIR CONDITIONS
DROUGHT CONDITIONS CONTINUE TO IMPACT STREAMFLOWS ACROSS PORTIONS OF
WESTERN AND NORTH CENTRAL NEBRASKA THROUGH THE MONTH OF
MAY....ALTHOUGH IMPROVEMENT IS BEING OBSERVED.
AT MID MAY...THE HIGHEST IMPACTS FROM THE DROUGHT WAS BEING OBSERVED
ACROSS THE NORTH AND SOUTH PLATTE RIVER BASINS...AND THE REPUBLICAN
RIVER BASIN. HOWEVER...NEAR NORMAL PRECIPITATION OVER THE FIRST HALF
OF MAY HAS HELPED TO BEGIN IMPROVEMENT IN THESE STREAMFLOWS. AT THIS
TIME...THESE AREAS WERE SEEING STREAMFLOWS BEING MEASURED BETWEEN 10
AND 30 PERCENT OF NORMAL FOR THIS TIME OF YEAR.
GROUND WATER LEVELS VARY ACROSS WESTERN AND NORTH CENTRAL NEBRASKA.
MUCH OF THE PANHANDLE AND SOUTHWEST NEBRASKA CONTINUE TO OBSERVE
LEVELS WELL BELOW NORMAL...EVEN THOUGH LEVELS ARE SHOWING SOME
IMPROVEMENT OVER THE PAST MONTH. MANY SITES STILL REMAIN BELOW 50
PERCENT OF NORMAL. THE SANDHILLS HAVE SEEN GROUND WATER LEVELS
RECHARGE OVER THE WINTER AND SPRINGTIME MONTHS...WITH LEVELS
INCREASING TO NEAR NORMAL.
SNOWPACK OVER THE MOUNTAINS IN THE SOURCE REGION OF THE NORTH AND
SOUTH PLATTE RIVERS HAS INCREASED SINCE MID APRIL. HOWEVER...RUNOFF
INTO THESE RIVERS IS FORECAST TO BE 30 TO 55 PERCENT OF NORMAL. IN
ADDITION...CONCERNING FLOW ALONG THE NORTH PLATTE RIVER...WATER
STORAGE FROM RESERVOIRS IS NEAR 45 PERCENT OF NORMAL...THEREFORE
LESS WATER WILL LIKELY BE RELEASED INTO THE RIVER THROUGH THE COMING
MONTHS TO KEEP STREAMFLOWS BELOW NORMAL LEVELS.
FIRE DANGER IMPACTS
ELEVATED FIRE CONCERNS CONTINUE LATE THIS SPRING AS AREA FUELS
REMAIN PRIME FOR BURNING. LOCAL FIRE MANAGEMENT OFFICERS CONTINUE
TO STRESS THAT ALL NATIVE FUELS WOULD CARRY FIRE...ESPECIALLY WITHIN
CURED 1 HR FUELS...WHICH RESPOND RAPIDLY TO CHANGES IN ATMOSPHERIC
MOISTURE.
FIRE ACTIVITY WILL CERTAINLY REMAIN ELEVATED THROUGH THE EARLY
SUMMER MONTHS UNLESS SIGNIFICANT PRECIPITATION WERE TO OCCUR.
EVEN THEN...LARGE FUELS SUCH AS THE PONDEROSA PINES FOUND ALONG THE
PINE RIDGE...MCKELVIE AND NEBRASKA NATIONAL FOREST WOULD REMAIN
PRIME FOR BURNING. A PROLONGED WET PERIOD WILL BE REQUIRED TO
ENTIRELY ALLEVIATE THE RISK OF EXTREME FIRE SPREAD WITHIN THE LARGE
FUELS.
BOTTOM LINE...ACTIVE FIRE ACTIVITY WILL CONTINUE TO BE A MAJOR
CONCERN THROUGH SUMMER...DESPITE THE LIMITED GREEN UP...UNLESS
SIGNIFICANT WIDESPREAD PRECIPITATION IS REALIZED.
