DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE NORTH PLATTE NE
1125 AM CDT THU APR 17 2014

...DROUGHT CONDITIONS CONTINUE ACROSS MOST OF WESTERN AND NORTH
CENTRAL NEBRASKA...

.SYNOPSIS...

A CONTINUATION OF THE WEATHER PATTERN THAT WAS IN PLACE THROUGHOUT
THE WINTER WAS THE STORY FOR MID MARCH THROUGH MID APRIL AS WELL.
WHILE SEVERAL SYSTEMS MOVED FROM NORTHWEST TO SOUTHEAST ACROSS
WESTERN AND NORTH CENTRAL NEBRASKA THROUGH THAT TIME...MOST OF THESE
EVENTS PRODUCED ONLY LIGHT PRECIPITATION AMOUNTS. THERE WERE A FEW
EXCEPTIONS TO THIS PATTERN...AND IN A COUPLE OF CASES...LOCALIZED
HEAVY SNOW BANDS DEVELOPED THAT PRODUCED SIGNIFICANT ACCUMULATIONS
OF SNOW AND ROAD CLOSURES. HOWEVER...AS THE AREA HEADS INTO THE TIME
OF YEAR WHEN MORE PRECIPITATION IS TYPICAL...MOST AREAS HAVE
RECEIVED LESS THAN AVERAGE PRECIPITATION FROM MID MARCH THROUGH MID
APRIL. ALSO...THE COLD NORTHERLY FLOW THAT WAS IN PLACE FOR MUCH OF
THE PERIOD PRODUCED COLDER THAN AVERAGE TEMPERATURES AS WELL.


.LOCAL AREAS AFFECTED...

AS OF APRIL 17...ACCORDING TO THE US DROUGHT MONITOR...SEVERE TO
EXTREME DROUGHT CONDITIONS WERE OCCURRING ROUGHLY SOUTH OF A LINE
FROM ERICSON...TO 10 MILES NORTH OF THEDFORD...TO 10 MILES SOUTH OF
ANTIOCH. NORTH OF THIS LINE...TO THE SOUTH DAKOTA
BORDER...ABNORMALLY DRY TO MODERATE DROUGHT CONDITIONS WERE
OCCURRING. ACROSS SOUTHWESTERN LINCOLN...SOUTHEASTERN
PERKINS...EASTERN CHASE...NORTHERN HAYES AND WESTERN FRONTIER
COUNTY...EXTREME DROUGHT CONDITIONS CONTINUED.


.CLIMATE SUMMARY...

TOTALS...OCTOBER 2013 TO MARCH 2014...THE PREVIOUS 3 MONTH
PRECIPITATION TOTALS...JANUARY TO MARCH...AND THE PRECIPITATION
TOTALS SO FAR IN APRIL...THROUGH APRIL 16.

.RIVER AND RESERVOIR CONDITIONS...

WITH THE EXCEPTION OF THE REPUBLICAN RIVER BASIN...RIVERS ACROSS
MOST OF WESTERN AND NORTH CENTRAL NEBRASKA ARE RUNNING AT NEAR OR
ABOVE NORMAL FLOWS FOR THIS TIME OF YEAR. THE REPUBLICAN RIVER BASIN
CONTINUES TO HAVE READINGS BETWEEN 10 AND 50 PERCENT.

THERE ARE AREAS THAT CONTINUE TO SEE BELOW NORMAL GROUNDWATER
DEPTHS...HOWEVER RECENT OBSERVATIONS ACROSS MUCH OF WESTERN AND
NORTH CENTRAL NEBRASKA SHOW READINGS NEAR NORMAL. PORTIONS OF THE
SANDHILLS EVEN HAD SOME PLACES WITH DEPTHS ABOVE NORMAL.
HOWEVER...SOUTHWEST NEBRASKA CONTINUES TO HAVE AREAS WITH WELL BELOW
NORMAL GROUND WATER DEPTHS. THESE AREAS ARE SEEING LEVELS BELOW 25
PERCENT OF NORMAL...AND GENERALLY LIE IN THE REPUBLICAN RIVER BASIN.

THE ELEVATION AT LAKE MCCONAUGHY HAS STAYED FAIRLY STEADY OVER THE
PAST MONTH. INFLOWS HAVE INCREASED AS THE SPRING SNOWMELT HAS
BEGUN...YET RELEASES HAVE ALSO BEGUN. INFLOWS AND OUTFLOWS HAVE BEEN
FAIRLY SIMILAR LEADING TO THE STEADY STATE OF THE ELEVATION. AT THE
SOURCE REGION OF THE NORTH AND SOUTH PLATTE RIVERS...SNOWPACK IN THE
MOUNTAINS IS ABOVE NORMAL...AT 125 TO 170 PERCENT OF NORMAL. THIS
WILL LEAD TO ABOVE NORMAL SNOWMELT INFLOWS INTO BOTH THE NORTH
PLATTE AND SOUTH PLATTE RIVER SYSTEMS THIS SPRING AND SUMMER.


.FIRE DANGER IMPACTS...

PRECIPITATION REMAINS WELL BELOW NORMAL FOR THIS TIME OF YEAR...THUS
VERY LITTLE GREEN-UP HAS OCCURRED AS OF THE THIRD WEEK OF APRIL.
FIRE AND LAND MANAGEMENT AGENCIES CONTINUE TO REPORT THAT AREA 1
HOUR FUELS ARE CURED AND WOULD BE THE PRIMARY CARRIER OF FIRE.
HIGHER SUN ANGLES AND WARMER TEMPERATURES OVER THE PAST COUPLE OF
WEEKS HAVE DRIED OUT 1 HOUR FUELS TO THE POINT WHERE THE
POTENTIAL FOR RAPID FIRE GROWTH CONTINUES TO INCREASE SIGNIFICANTLY.

THE RECENT SYNOPTIC WEATHER PATTERN HAS FAVORED EPISODIC PERIODS OF
EXTREMELY DRY AIR WHEN WIND SPEEDS HAVE GUSTED IN EXCESS OF 25
MPH...THIS COMBINATION COMBINED WITH THE CURED FUELS HAS ALLOWED FOR
NUMEROUS LARGE RANGE FIRES.

BOTTOM LINE...UNTIL GREEN-UP CAN FULLY COMMENCE ACROSS WESTERN AND
NORTH CENTRAL NEBRASKA...EXPLOSIVE FIRE GROWTH WILL REMAIN CERTAIN
DUE TO THE COMBINATION OF DRY FUELS...GUSTY WINDS AND LOW RELATIVE
HUMIDITIES.

OUTLOOK COVERING APRIL 22ND THROUGH THE 26TH IS FOR ABOVE AVERAGE
TEMPERATURES ACROSS ALL OF WESTERN AND NORTH CENTRAL NEBRASKA. THE

PRECIPITATION. THE LATEST 90 DAY OUTLOOK...COVERING MAY...JUNE AND
