DROUGHT INFORMATION STATEMENT...CORRECTED TO ADD 90 DAY OUTLOOK
NATIONAL WEATHER SERVICE NORTH PLATTE NE
922 AM CDT FRI AUG 22 2014

...MODERATE DROUGHT AREA SHRINKS SLIGHTLY ACROSS WESTERN AND NORTH
CENTRAL NEBRASKA OVER THE PAST MONTH...

.SYNOPSIS...

PERSISTENT RIDGING ACROSS THE WESTERN PORTION OF THE
COUNTRY...HIGHLIGHTED THE WEATHER PATTERN DURING THE LATTER HALF OF
JULY INTO THE FIRST WEEK OF AUGUST. THIS LED TO MUCH BELOW NORMAL
RAINFALL FOR THE MONTH OF JULY. NORTH PLATTE RECORDED ITS DRIEST
JULY ON RECORD WITH 0.14 INCHES OF PRECIPITATION. VALENTINE ONLY
RECORDED 0.58 INCHES OF PRECIPITATION FOR JULY WHICH WAS 2.63 INCHES
BELOW NORMAL. BY THE END OF THE FIRST WEEK OF AUGUST...THE UPPER
LEVEL PATTERN BEGIN TO SHIFT SLIGHTLY AS AN ACTIVE NORTHERN STREAM
COMMENCED ACROSS THE NORTHERN TIER OF STATES. THIS FLOW
ALOFT...SUPPRESSED RIDGING ACROSS THE WESTERN PART OF THE
COUNTRY...LEADING TO A MORE ACTIVE PATTERN ACROSS WESTERN AND NORTH
CENTRAL NEBRASKA. THIS ACTIVE PATTERN HAS LED TO NORMAL TO ABOVE
NORMAL RAINFALL ACROSS WESTERN AND NORTH CENTRAL NEBRASKA DURING THE
SECOND WEEK OF AUGUST. OVER THE NEXT SEVERAL DAYS...A TROUGH OF LOW
PRESSURE WILL DEVELOP ACROSS THE INTER MOUNTAIN WEST. THIS PATTERN
TYPICALLY LEADS TO ABOVE NORMAL PRECIPITATION ACROSS WESTERN AND
NORTH CENTRAL NEBRASKA.

DROUGHT CONDITIONS WERE OCCURRING IN PORTIONS OF SOUTHWEST
NEBRASKA...MAINLY SOUTHERN LINCOLN AND MOST OF HAYES AND FRONTIER

OF A LINE FROM OGALLALA TO MULLEN TO BROKEN BOW.

.RIVER AND RESERVOIR CONDITIONS...

WITH THE EXCEPTION OF THE REPUBLICAN RIVER BASIN ACROSS SOUTHWEST
NEBRASKA...RIVERS ACROSS MOST OF WESTERN AND NORTH CENTRAL NEBRASKA
ARE RUNNING AT NEAR OR ABOVE NORMAL FLOWS FOR THIS TIME OF YEAR.
ACROSS THE REPUBLICAN RIVER BASIN...STREAMFLOWS ARE AVERAGING 10 TO
24 PERCENT BELOW NORMAL. THIS BASIN INCLUDES FRENCHMAN AND STINKING
WATER CREEKS IN THE LOCAL AREA.

WITH THE GROWING/IRRIGATION SEASON ONGOING...GROUNDWATER DEPTHS HAVE
DROPPED OVER THE LAST 30 DAYS. IN THE REPUBLICAN RIVER BASIN ACROSS
SOUTHWEST NEBRASKA...SOME WELLS AND SPRINGS WERE MEASURING AT 10 TO
25 PERCENT OF NORMAL. MUCH OF THE REMAINDER OF WESTERN AND NORTH
CENTRAL NEBRASKA CONTINUES TO SEE GROUNDWATER DEPTHS NEAR NORMAL FOR
THIS TIME OF YEAR.

GENERALLY DRY CONDITIONS OVER THE PAST MONTH HAVE BROUGHT AN
INCREASE IN IRRIGATION DEMANDS. THE HIGHER DEMAND HAS LED TO
INCREASED OUTFLOWS FROM LAKE MCCONAUGHY. IN ADDITION...INFLOWS INTO
THE LAKE HAVE DROPPED DUE TO A LACK IN SURFACE RUNOFF ALONG WITH
LESSER AMOUNTS COMING THROUGH THE SYSTEM FROM THE RESERVOIR SYSTEM
OVER WYOMING. THIS HAS LED TO A DECREASE IN THE LAKE LEVEL AS OF
LATE AUGUST...WITH A DROP OF JUST OVER 4 FEET IN THE PAST MONTH. IT
IS CURRENTLY AT 59 PERCENT OF CAPACITY WHICH IS 5 PERCENT LOWER THAN
A MONTH AGO. ALSO OF NOTE...THE LAKE LEVEL IS ABOUT 11 PERCENT
HIGHER THAN WAS MEASURED ONE YEAR AGO.


.FIRE DANGER IMPACTS...

AS OF THE SECOND WEEK OF AUGUST...THE NATIVE 1-HOUR FUELS ARE
SHOWING SIGNS OF CURING ACROSS ALL OF WESTERN AND NORTH CENTRAL
NEBRASKA. INVASIVE 1 HOUR FUELS...SUCH AS CHEAT GRASS...HAVE CURED
AND ARE PRIME FOR CONSUMPTION.  THE WET SPRING HAS ALLOWED FOR
ABUNDANT FUELS ACROSS THE REGION...AND ONCE THESE FUELS CURE
COMPLETELY...THE THREAT OF EXTREME FIRE GROWTH WILL INCREASE
GREATLY. THIS TYPICALLY OCCURS BY LATE SUMMER.

SEVERAL SMALL FIRES /LESS THAN 300 ACRES/ HAVE BEEN NOTED RECENTLY
ACROSS THE SANDHILLS REGION OF NEBRASKA. THE SPREAD OF THESE FIRES
HAS BEEN SLOWED BY AN ABUNDANCE OF LOWER BOUNDARY LAYER MOISTURE.

BOTTOM LINE...CONTINUED CURING OF THE FINE FUELS /1-HOUR/ WILL
INCREASE THE THREAT OF EXTREME FIRE GROWTH ACROSS WESTERN AND NORTH
CENTRAL NEBRASKA INTO EARLY FALL...PROVIDED THAT ATMOSPHERIC
CONDITIONS FAVOR GUSTY WIND AND DRY BOUNDARY LAYER MOISTURE.

.PRECIPITATION/TEMPERATURE OUTLOOK...

THE LATEST 6 TO 10 DAY OUTLOOK...COVERING THE PERIOD FROM AUGUST
28TH THROUGH THE 30TH CALLS FOR BELOW AVERAGE TEMPERATURES ACROSS
ALL OF WESTERN AND NORTH CENTRAL NEBRASKA...WITH THE BEST CHANCE
FROM OSHKOSH TO ONEILL. THERE ARE BETTER CHANCES FOR ABOVE AVERAGE
PRECIPITATION AS WELL DURING THAT PERIOD ACROSS THE AREA.

THE LATEST 8 TO 14 DAY OUTLOOK...COVERING AUGUST 28TH THROUGH
SEPTEMBER 3RD...CONTINUES THE BETTER CHANCES FOR BELOW AVERAGE
TEMPERATURES ACROSS THE AREA. FOR PRECIPITATION FOR THE SAME
PERIOD...THERE IS A SLIGHTLY BETTER CHANCE FOR ABOVE AVERAGE
PRECIPITATION EAST OF THE PANHANDLE.

THE LATEST ONE MONTH OUTLOOK FOR SEPTEMBER CALLS FOR EQUAL CHANCES
FOR BELOW...AVERAGE AND ABOVE AVERAGE TEMPERATURES ACROSS WESTERN
AND NORTH CENTRAL NEBRASKA. FOR PRECIPITATION FOR THE MONTH OF
SEPTEMBER...THERE IS A BETTER CHANCE FOR ABOVE AVERAGE PRECIPITATION
ACROSS ALL OF WESTERN AND NORTH CENTRAL NEBRASKA...ESPECIALLY ALONG
AND SOUTH OF THE INTERSTATE 80 CORRIDOR.

THE 3 MONTH TEMPERATURE OUTLOOK FOR SEPTEMBER...OCTOBER AND NOVEMBER
FOR WESTERN AND NORTH CENTRAL NEBRASKA CALLS FOR SLIGHTLY BETTER
CHANCES FOR BELOW AVERAGE TEMPERATURES ACROSS AREAS SOUTH OF
INTERSTATE 80. ELSEWHERE EQUAL CHANCES FOR ABOVE...BELOW AND NEAR
AVERAGE TEMPERATURES ARE FORECAST. THE 3 MONTH OUTLOOK FOR
PRECIPITATION CONTINUES THE SLIGHTLY BETTER CHANCES FOR ABOVE
AVERAGE PRECIPITATION ACROSS ALL OF WESTERN AND NORTH CENTRAL
NEBRASKA FOR THE MONTHS OF SEPTEMBER...OCTOBER AND NOVEMBER.
