...DROUGHT CONDITIONS PERSIST IN PORTIONS OF THE TENNESSEE
VALLEY...

.SYNOPSIS:

.Drought intensity and extent:
According to the U.S. Drought Monitor valid Tuesday, August 30th,
2022, D1 (Moderate Drought) conditions continue in western
portions of Lauderdale County and far northwestern portions of
Colbert County. This includes areas northwest of Cherokee and west
of Wright, but including Waterloo to PickWick Lake. Meanwhile, D0
(Abnormally Dry) conditions are present generally along and near
the Tennessee River from around Cherokee and the Quad Cities, to
Decatur, Huntsville, and eastward to Grant and Woodville areas.
Another narrow swath of D0 conditions was present from northwest
to southeast across Franklin County (AL), which includes the
Russellville area, into western portions of the Bankhead National
Forest. Although dry and drought conditions do persist in all of
the afore-mentioned areas, this represents an improvement in
conditions over the last month.

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 generally averaged around two to three degrees above
normal (F) from about mid-June through July. However,
temperatures have averaged near to slightly below normal during
the month of August.

.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. This lack
of rainfall combined with above normal temperatures led to rapid
drought development in the area earlier this summer. Then,
rainfall from shower activity began to increase across the area
during the month of July, which helped to curb further drought
intensification. During the month of August, precipitation was
spotty as can often be the case in the Tennessee Valley, with some
areas receiving above normal rainfall, and others receiving below
normal rainfall. Nevertheless, rainfall deficits around one to
two inches continued to maintain designations for Abnormally Dry
and Moderate Drought conditions in the areas noted above.

.Hydrologic conditions:
Streamflows tended to rebound to some degree during July and
August. However, climatologically low flows remain on the Paint
Rock River and Big Nance Creek. Seven-day average streamflow at
Big Nance Creek was only at the 16th percentile at the end of
August, while flow was at the 19th percentile on the Paint Rock
River at Woodville.

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 30th percentiles in
portions of the Abnormally Dry and D1 (Moderate Drought) 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 in July into early
August stated that producers reported corn yields may be below
average this year, particularly in drought affected areas. Some
corn producers in particular have indicated that rainfall may not
have been timely enough during crucial stages of the corn`s
development or sufficient to avoid yield losses. More recent
reports in late August, however, have indicated that maturing
neared completion and harvest began in areas where moisture levels
allowed.

Local news from the Muscle Shoals area in Colbert County in late
August reported that produce for a local farmer`s market is down
about 50% from normal this summer.

.Fire hards:
Keetch-Byram Drought Index indicates values around 500 to 600 were
present across abnormally dry and drought-stricken areas. Values
in this range indicate that lower litter and duff layers actively
contribute to fire intensity and will burn actively. Additionally,
values indicate approximately five to six inches of rainfall would
be needed to help abate dry and drought conditions, per this
index.

.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. As of the latest release from ADECA, on
August 31st, 2022, this area in northern Alabama (Drought Region
1) remained in a Drought Advisory.

.LOCAL DROUGHT OUTLOOK:
Temperatures are expected to average near to slightly below normal
with chances for showers and thunderstorms returning to the area
on Friday (Sep 2). Chances for showers and thunderstorms will
increase for Sunday into early next week. Due to the showery
nature of precipitation, rainfall totals will vary widely.
Although, widespread amounts could range from around 0.5 to 1.5
inches over the next week. However, amounts can be much higher in
local areas.

The 8-14 Day Outlook from the Climate Prediction Center (CPC)
valid for the period September 8-14 favors above normal
precipitation and temperatures for the area.

The Monthly Outlook for September slightly favors above normal
precipitation. However, the Temperature Outlook indicates Equal
Chances for either below, near or above normal temperatures.
Essentially, there is no strong signal in the large scale sub-
seasonal pattern with regards to temperatures for the region for
the month of September.

.NEXT ISSUANCE DATE:
The next drought statement will be issued on or shortly after
September 29th, as conditions warrant. Statements may be issued
prior to September 29th if conditions change significantly across
the area.
