DROUGHT INFORMATION STATEMENT  
NATIONAL WEATHER SERVICE HUNTSVILLE AL  
450 PM CDT THU AUG 4 2022  
 
...DROUGHT CONDITIONS PERSIST IN PORTIONS OF THE TENNESSEE  
VALLEY...  
 
.SYNOPSIS:  
 
.DROUGHT INTENSITY AND EXTENT:  
ACCORDING TO THE U.S. DROUGHT MONITOR VALID TUESDAY, AUGUST 2ND,  
2022, D2 (SEVERE DROUGHT) CONDITIONS CONTINUE IN WESTERN PORTIONS  
OF LAUDERDALE COUNTY AND HAVE RECENTLY EXPANDED TO INCLUDE FAR  
NORTHWESTERN PORTIONS OF COLBERT COUNTY. THIS INCLUDES AREAS  
NORTHWEST OF CHEROKEE AND WEST OF WRIGHT, BUT INCLUDING WATERLOO  
TO PICKWICK LAKE. MEANWHILE, D1 (MODERATE DROUGHT) CONDITIONS HAVE  
DECREASED A LITTLE ACROSS NORTHERN ALABAMA, BUT STILL ENCOMPASS  
OTHER PORTIONS OF LAUDERDALE AND COLBERT COUNTIES, STRETCHING  
EASTWARD THROUGH PORTIONS OF LIMESTONE, LAWRENCE, MORGAN, MADISON  
AND JACKSON COUNTIES. IT SHOULD BE NOTED THAT D1 CONDITIONS HAVE  
BEEN REMOVED FROM NORTHWESTERN FRANKLIN COUNTY, AL, AND ONLY A  
VERY SMALL PORTION OF MORGAN COUNTY IS STILL DESIGNATED IN D1  
CONDITIONS, MAINLY IN FAR WESTERN PORTIONS OF DECATUR AND NORTH OF  
TRINITY.  
 
D1 DROUGHT DESIGNATIONS HAVE BEEN REMOVED FROM LINCOLN, MOORE AND  
FRANKLIN COUNTIES IN TENNESSEE. HOWEVER, A D0 (ABNORMALLY DRY)  
DESIGNATION REMAINS ACROSS ALL OF THESE COUNTIES.  
 
PLEASE SEE THE U.S. DROUGHT MONITOR WEB PAGE (INCLUDED IN THE  
RELATED WEB SITES SECTION BELOW) FOR FURTHER INFORMATION,  
INCLUDING A GRAPHICAL AND NARRATIVE DEPICTION OF THIS WEEK'S U.S.  
DROUGHT MONITOR.  
 
THE U.S. DROUGHT MONITOR CLASSIFIES DROUGHT WITHIN ONE OF THESE  
FIVE CATEGORIES:  
 
D0...ABNORMALLY DRY  
D1...MODERATE DROUGHT  
D2...SEVERE DROUGHT  
D3...EXTREME DROUGHT  
D4...EXCEPTIONAL DROUGHT  
 
.TEMPERATURES:  
TEMPERATURES HAVE GENERALLY AVERAGED AROUND TWO TO THREE DEGREES  
ABOVE NORMAL (F) SINCE ABOUT MID-JUNE.  
 
.PRECIPITATION:  
PRECIPITATION DEFICITS BEGAN TO BUILD IN THE REGION DURING THE  
MONTH OF JUNE. FOR EXAMPLE, FROM JUNE 9TH THROUGH THE END OF JUNE,  
MUSCLE SHOALS ONLY RECEIVED 0.01 INCH OF RAINFALL. DURING THE SAME  
PERIOD, HUNTSVILLE RECEIVED ONLY 0.04 INCH OF RAINFALL. THEN,  
RAINFALL FROM SHOWER ACTIVITY BEGAN TO INCREASE ACROSS THE AREA  
DURING THE MONTH OF JULY. SOME LOCATIONS PREVIOUSLY UNDER DROUGHT  
DESIGNATIONS, IN PARTICULAR IN THE TENNESSEE COUNTIES, EXPERIENCED  
RAINFALL AMOUNTS AROUND ONE TO FOUR INCHES ABOVE NORMAL. IN  
ADJACENT PORTIONS OF FAR NORTHERN ALABAMA, NEAR THE TENNESSEE  
BORDER, PRECIPITATION SURPLUSES ALSO BUILT DURING JULY. THESE  
SHORTER TIMESCALE PRECIPITATION SURPLUSES (<=30 DAYS) WERE  
SUFFICIENT TO LEAD TO DROUGHT IMPROVEMENTS IN THESE AREAS.  
HOWEVER, ON LONGER TIMESCALES OF 60 TO 90 DAYS, PRECIPITATION  
DEFICITS STILL REMAIN, ESPECIALLY IN CURRENT AREAS WITH D1 AND D2  
DROUGHT DESIGNATIONS.  
 
.HYDROLOGIC CONDITIONS:  
STREAMFLOWS HAVE REBOUNDED TO SOME DEGREE DUE TO RAINFALL IN JULY,  
HOWEVER SOME STREAMS REMAIN AT CLIMATOLOGICALLY LOW FLOW DUE TO  
THE OVERALL DRY SEASONAL CONDITIONS. FOR EXAMPLE, 7-DAY AVERAGE  
STREAMFLOW AT BEAR CREEK IS AT THE 24TH PERCENTILE FOR THIS TIME  
OF YEAR.  
 
SOIL MOISTURE DATA FROM THE NASA SHORT-TERM PREDICTION RESEARCH  
AND TRANSITION (NASA SPORT) CENTER INDICATE THAT 0-2 METER SOIL  
MOISTURE IS GENERALLY AROUND THE 10TH TO 20TH PERCENTILES ACROSS  
DROUGHT-STRICKEN AREAS. ALTHOUGH, SOIL MOISTURE CAN VARY MARKEDLY  
WITHIN SMALL AREAS DUE TO THE SHOWERY NATURE OF PRECIPITATION  
THIS TIME OF YEAR.  
 
.SUMMARY OF IMPACTS:  
 
.AGRICULTURAL IMPACTS:  
REPORTS FROM THE U.S. DEPARTMENT OF AGRICULTURE ON JULY 5TH  
INDICATED THAT PRODUCERS REPORTED CORN AND SOYBEAN YIELDS MAY BE  
BELOW AVERAGE IF THE STATE OF ALABAMA CONTINUED TO EXPERIENCE DRY,  
HOT WEATHER. THE REPORT STATED THAT SOME CORN CROPS WERE  
EXPERIENCING STUNTED GROWTH, WHILE SOME SOYBEANS WERE SHOWING  
SIGNS OF STRESS. WHILE CATTLE CONTINUED TO BE IN MOSTLY GOOD  
CONDITION, LIVESTOCK CONTINUED TO EXPERIENCE HEAT STRESS AND MANY  
CATTLE PRODUCERS WERE SUPPLEMENTING FEED. MORE RECENT REPORTS FROM  
THE USDA HAVE INDICATED THAT RAINFALL DURING JULY HAD HELPED TO  
REPLENISH SOIL MOISTURE LEVELS TO SOME EXTENT. HOWEVER, SOME CORN  
PRODUCERS IN PARTICULAR HAVE INDICATED THAT RAINFALL MAY NOT HAVE  
BEEN TIMELY ENOUGH OR SUFFICIENT TO AVOID YIELD LOSSES THIS YEAR.  
 
.FIRE HARDS:  
THE KEETCH-BYRAM DROUGHT INDEX INDICATES VALUES AROUND 400 TO 600  
ACROSS DROUGHT-STRICKEN AREAS, WITH THE HIGHEST VALUES (500-600)  
IN THE D2 DROUGHT DESIGNATED AREAS. VALUES IN THIS RANGE ARE MORE  
TYPICAL OF LATE SUMMER AND EARLY FALL, AND INDICATE THAT LOWER  
LITTER AND DUFF LAYERS ACTIVELY CONTRIBUTE TO FIRE INTENSITY AND  
WILL BURN ACTIVELY.  
 
.DROUGHT MITIGATION ACTIONS:  
 
ON JUNE 29TH, 2022, THE ALABAMA DEPARTMENT OF ECONOMIC AND  
COMMUNITY AFFAIRS (ADECA) PLACED ALL OF NORTHERN ALABAMA IN A  
DROUGHT ADVISORY. ACCORDING TO THE ALABAMA DROUGHT MANAGEMENT  
PLAN, WHEN UNDER A DROUGHT ADVISORY, WATER MANAGERS ARE URGED TO  
CAREFULLY MONITOR CONDITIONS AND ENCOURAGE THE WISE AND EFFICIENT  
USE OF WATER RESOURCES.  
 
.LOCAL DROUGHT OUTLOOK:  
TEMPERATURES ARE EXPECTED TO AVERAGE A LITTLE ABOVE NORMAL THROUGH  
ABOUT MONDAY, AND ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS  
ARE EXPECTED EACH DAY, MAINLY IN THE AFTERNOON. HOWEVER, NEAR TO  
BELOW NORMAL TEMPERATURES ARE EXPECTED AFTERWARD NEXT WEEK AS  
CLOUDS AND CHANCES FOR PRECIPITATION INCREASE AS A FRONT MOVES  
INTO THE REGION. WIDESPREAD PRECIPITATION AMOUNTS ARE FORECAST TO  
RANGE FROM AROUND 0.5 TO 1.5 INCHES OVER THE NEXT WEEK. HOWEVER,  
AMOUNTS CAN BE CONSIDERABLY MORE OR LESS DUE TO THE SHOWERY  
PRECIPITATION.  
 
THE 8-14 DAY OUTLOOK FROM THE CLIMATE PREDICTION CENTER (CPC)  
VALID FOR THE PERIOD AUGUST 12-18 INDICATES NEAR NORMAL  
TEMPERATURES ARE FAVORED FOR MOST OF THE AREA, WITH THE EXCEPTION  
OF FAR NW ALABAMA, WHERE ABOVE NORMAL TEMPERATURES ARE SLIGHTLY  
FAVORED. BELOW NORMAL PRECIPITATION IS SLIGHT FAVORED FOR THE  
AREA.  
 
THE MONTHLY OUTLOOK FOR AUGUST INDICATES THAT ABOVE NORMAL  
TEMPERATURES ARE FAVORED FOR ALL OF THE AREA, WHILE THERE ARE  
EQUAL CHANCES FOR BELOW, NEAR, OR ABOVE NORMAL PRECIPITATION.  
ESSENTIALLY, THERE IS NO STRONG CLIMATE SIGNAL AT THIS TIME WITH  
REGARDS TO PRECIPITATION AMOUNTS FOR THE REGION FOR THE MONTH OF  
AUGUST.  
 
.NEXT ISSUANCE DATE:  
THE NEXT DROUGHT STATEMENT WILL BE ISSUED ON OR SHORTLY AFTER  
SEPTEMBER 1ST, AS CONDITIONS WARRANT. STATEMENTS MAY BE ISSUED  
PRIOR TO SEPTEMBER 1ST IF CONDITIONS DETERIORATE SIGNIFICANTLY OR  
IF DROUGHT CONDITIONS IMPROVE ACROSS THE AREA.
