SUMMARY OF IMPACTS
 
 
   
FIRE DANGER IMPACTS
 
 
ABOVE NORMAL TEMPERATURES AND BELOW NORMAL PRECIPITATION PRODUCED  
MODERATE TO HIGH FIRE DANGER. 10-HOUR FUEL MOISTURE RANGED FROM THE  
3RD TO 6TH PERCENTILES. 1000-HOUR FUEL MOISTURE RANGED FROM THE 11TH  
TO 15TH PERCENTILES.  
   
AGRICULTURAL IMPACTS
 
 
AS OF JULY 31, APPROXIMATELY 10 PERCENT OF WYOMING WAS DROUGHT-FREE,  
27 PERCENT WAS ABNORMALLY DRY, 38 PERCENT EXPERIENCED MODERATE

EXPERIENCED EXTREME DROUGHT. FARMERS AND RANCHERS WERE EXPERIENCING  
LOW GRASS YIELDS IN CARBON COUNTY. SOME PRODUCERS WERE PULLING  
LIVESTOCK FROM SUMMER GRAZING LANDS 3 TO 4 WEEKS EARLY. SOME FIELDS  
BENEFITED FROM ISOLATED RAINS IN NORTHERN GOSHEN COUNTY, WHILE  
SOUTHERN AREAS REMAINED VERY DRY. FIELDS WERE DRYING OUT IN NIOBRARA  
COUNTY. MUCH OF PLATTE COUNTY WAS DRY AND THE NEED FOR MORE MOISTURE  
WAS CRITICAL. IRRIGATION WATER SUPPLIES WERE 36 PERCENT POOR TO VERY  
POOR, 17 PERCENT FAIR AND 47 PERCENT ADEQUATE. STOCK WATER SUPPLIES  
WERE 49 PERCENT SHORT TO VERY SHORT AND 51 PERCENT ADEQUATE. TOPSOIL  
MOISTURE WAS 63 PERCENT SHORT TO VERY SHORT AND 37 PERCENT ADEQUATE.  
SUBSOIL MOISTURE WAS 66 PERCENT SHORT TO VERY SHORT AND 34 PERCENT  
ADEQUATE. WINTER WHEAT WAS 58 PERCENT POOR TO VERY POOR AND 29 PERCENT  
FAIR. PASTURE AND RANGE CONDITIONS WERE 27 PERCENT POOR TO VERY POOR  
AND 23 PERCENT FAIR.  
 
AS OF JULY 31, NEBRASKA TOPSOIL MOISTURE WAS WAS 70 PERCENT SHORT TO  
VERY SHORT AND 30 PERCENT ADEQUATE. SUBSOIL MOISTURE WAS 69 PERCENT  
SHORT TO VERY SHORT AND 31 PERCENT ADEQUATE. CORN WAS 22 PERCENT  
POOR TO VERY POOR AND 24 PERCENT FAIR. WINTER WHEAT HARVESTED WAS  
92 PERCENT, 4 PERCENT ABOVE THE AVERAGE. PASTURE AND RANGE CONDITIONS  
WERE 62 PERCENT POOR TO VERY POOR AND 25 PERCENT FAIR.  
   
SOIL MOISTURE
 
 
SOIL MOISTURE DEFICITS VARIED FROM 40 TO 60 MM IN SOUTHEAST WYOMING,  
TO 60 TO 80 MM ACROSS THE NEBRASKA PANHANDLE. CROP MOISTURE INDICES  
WERE -3.0 OR LESS, INDICATIVE OF SEVERELY DRY CONDITIONS.  
   
HYDROLOGIC CONDITIONS
 
 
STREAMFLOWS ON THE NORTH PLATTE RIVER WERE OBSERVED AT NORMAL LEVELS  
(25TH TO 75TH PERCENTILES). MUCH BELOW NORMAL FLOWS (LESS THAN 10TH  
PERCENTILE) WERE OBSERVED ON THE MEDICINE BOW RIVER ABOVE SEMINOE  
RESERVOIR AND DEER CREEK NEAR GLENROCK, WYOMING. BELOW NORMAL FLOWS  
(10TH TO 24TH PERCENTILE) WERE OBSERVED AT ROCK CREEK ABOVE KING

PRECIPITATION/TEMPERATURE OUTLOOK
 
 
BELOW AVERAGE SEA SURFACE TEMPERATURES WEAKENED ACROSS MOST OF THE CENTRAL  
AND EASTERN EQUATORIAL PACIFIC IN JULY. THE WEEKLY NINO-3.4 INDEX RANGED  
FROM -0.4C TO -1.2C. LA NINA IS FAVORED TO CONTINUE THROUGH THE END OF  
2022 WITH THE ODDS FOR LA NINA DECREASING INTO LATE SUMMER (60 PERCENT  
CHANCE AUGUST AND SEPTEMBER) BEFORE INCREASING THIS FALL AND EARLY WINTER  
(62 TO 66 PERCENT CHANCE).  
 
THE AUGUST 2022 OUTLOOK ISSUED BY THE CLIMATE PREDICTION CENTER CALLS  
FOR A 33 TO 50 PERCENT CHANCE OF ABOVE NORMAL TEMPERATURES. EQUAL CHANCES  
(33 PERCENT) OF ABOVE, BELOW OR NEAR NORMAL PRECIPITATION IS PREDICTED  
FOR MUCH OF SOUTHEAST WYOMING AND FAR SOUTHWEST NEBRASKA PANHANDLE. THE  
REMAINDER OF THE NEBRASKA PANHANDLE AND FAR EASTERN WYOMING INDICATES A  
33 TO 40 PERCENT OF BELOW NORMAL PRECIPITATION.  
 
THE AUGUST THROUGH OCTOBER 2022 OUTLOOK PREDICTS A 33 TO 50 PERCENT  
CHANCE OF ABOVE NORMAL TEMPERATURES AND A 33 TO 50 PERCENT CHANCE OF  
BELOW NORMAL PRECIPITATION.  
 
THE SEASONAL DROUGHT OUTLOOK THROUGH OCTOBER 2022 IMPROVEMENT IN DROUGHT  
CONDITIONS ACROSS FAR SOUTHERN WYOMING AND SOUTHWEST CORNER OF THE  
NEBRASKA PANHANDLE. DROUGHT PERSISTENCE AND DEVELOPMENT IS EXPECTED  
FOR THE REMAINDER OF THE PANHANDLE INTO PORTIONS OF EASTERN AND  
SOUTHEAST WYOMING.
