...DROUGHT SUMMARY...

...LATEST OUTLOOK PLACES AN ENHANCED RISK OF DROUGHT DEVELOPMENT 
ACROSS THE TRI STATE AREA FOR THE UPCOMING SPRING...

...SUMMARY OF DROUGHT MONITOR...

IN THE FEBRUARY 14TH RELEASE OF THE U.S. DROUGHT MONITOR...MODERATE 
DROUGHT CONDITIONS PERSISTED ACROSS SOUTHWEST NEBRASKA. THE IMPACTS 
IN THIS AREA WERE PRIMARILY HYDROLOGICAL (WATER) AND NOT 
AGRICULTURAL. ABNORMALLY DRY CONDITIONS WERE INDICATED ACROSS THE 
REMAINDER OF THE TRI STATE AREA.

THE DROUGHT MONITOR FOCUSES ON BROAD-SCALE CONDITIONS. LOCAL 
CONDITIONS MAY VARY.

THE U.S. DROUGHT MONITOR IS A WEEKLY COLLABORATIVE EFFORT BETWEEN A 
NUMBER OF FEDERAL AGENCIES INCLUDING NOAA/NWS...THE U.S. DEPARTMENT 
OF AGRICULTURE...AND THE NATIONAL DROUGHT MITIGATION CENTER. 

...HYDROLOGIC SUMMARY...

A SMALL PORTION OF THE AREA RECEIVED ABOVE NORMAL PRECIPITATION IN 
THE MONTH OF JANUARY. THIS WAS THE RESULT OF ONE STORM. DURING THE 
EVENING HOURS OF THE 19TH AND 20TH...AN UPPER LEVEL STORM SYSTEM 
PRODUCED A BAND OF MODERATE SNOW FROM EAST CENTRAL COLORADO INTO 
PORTIONS OF NORTHWEST KANSAS. NORMAL PRECIPITATION RANGES FROM NEAR 
A THIRD OF AN INCH IN THE WESTERN PORTION OF THE AREA TO AROUND SIX 
TENTHS OF AN INCH IN THE EASTERN PORTION.

NO RIVERS REACHED FLOOD STAGE DURING THE MONTH OF JANUARY.

...LOCAL AREAS IMPACTED...

DROUGHT LEVELS...
D0 -- ABNORMALLY DRY OR RECOVERING FROM DROUGHT
D1 -- MODERATE DROUGHT
D2 -- SEVERE DROUGHT
D3 -- EXTREME DROUGHT
D4 -- EXCEPTIONAL DROUGHT

PERCENT NORMALS OF PRECIPITATION ARE THE AVERAGE ACROSS A COUNTY FOR 
THE INDICATED PERIOD. LOCAL CONDITIONS MAY VARY. A VALUE OF 100 
WOULD BE THE CLIMATOLOGICAL NORMAL...A VALUE OF 50 WOULD BE HALF OF 
NORMAL AND CONSIDERED DRY...WHILE A VALUE OF 200 WOULD BE TWICE 
NORMAL AND CONSIDERED VERY WET. 

DROUGHT LEVEL AS OF FEBRUARY 14 2006.

...PALMER DROUGHT SEVERITY INDEX...

THE PALMER DROUGHT SEVERITY INDEX (PDSI) IS ONE OF THE OLDEST AND 
MOST WIDELY USED MEASURES FOR ASSESSING METEOROLOGICAL DROUGHT IN 
THE U.S. IT HAS BEEN CALCULATED BACK FOR OVER 100 YEARS AND ALLOWS 
FOR LONG-TERM DROUGHT COMPARISONS. SINCE THESE ARE DONE FOR 
CLIMATOLOGICAL ZONES OVER MANY COUNTIES...THERE MAY BE SOME 
DIFFERENCES DUE TO LOCAL PRECIPITATION AMOUNTS AND DIFFERENT TIME 
PERIODS. 

THE CATEGORIES FOR THE PDSI ARE AS FOLLOWS:

EXTREME DROUGHT     : -4.00 OR LESS
SEVERE DROUGHT      : -3.00 TO -3.99
MODERATE DROUGHT    : -2.00 TO -2.99
MILD DROUGHT        : -1.00 TO -1.99
NEAR NORMAL         : +0.99 TO -0.99
MOIST SPELL         : +1.00 TO +1.99
UNUSUAL MOIST SPELL : +2.00 TO +2.99
VERY MOIST          : +3.00 TO +3.99
EXTREMELY MOIST     : +4.00 OR MORE

AS OF THE WEEK ENDING FEBRUARY 11 2006 THESE ARE THE CURRENT LONG TERM 
PDSI NUMBERS FOR THE TRI STATE AREA:

STATE   CLIMATE DIVISION (NO.)     PDSI     CATEGORY

...OUTLOOKS...

THE LATEST SEASONAL DROUGHT OUTLOOK WAS RELEASED BY THE CLIMATE 
PREDICTION CENTER ON FEBRUARY 16 AND IS VALID THROUGH MAY 2006.

MODERATE DROUGHT CONDITIONS ARE EXPECTED TO PERSIST ACROSS PORTIONS 
OF SOUTHWEST NEBRASKA. ELSEWHERE IN THE TRI STATE AREA...THERE IS A 
RISK THAT THE DROUGHT CURRENTLY AFFECTING THE SOUTHERN PLAINS COULD 
SPREAD NORTHWARD ACROSS KANSAS AND EASTERN COLORADO AND MERGE WITH 
THE DROUGHT IN NEBRASKA AND IOWA.
