Drought Information Statement
National Weather Service Huntsville AL
924 AM CST Thu Mar 8 2018

...The Last Remnants of the Drought Have Disappeared from
Northeastern Alabama...

According to the Drought Monitor valid Tuesday, March 6th, 2018,
Moderate Drought (D1) conditions have been removed from the remaining
areas of DeKalb and Jackson Counties in northeastern Alabama. Only
Abnormally Dry (D0) conditions remain in parts of northeastern
Alabama and southern Cullman County.

Note: Precipitation and other conditions (streamflows, soil
moisture, etc.) that determine drought designations each week for
the U.S. Drought Monitor are based on data that end at 6 AM CST each
Tuesday. So, any precipitation or changes in conditions that occurs
between Tuesday morning and the issuance of the Drought Information
Statement (usually on Thursdays) are not factored into the latest
drought designations, but will be considered for the next week`s
U.S. Drought Monitor issuance. Also, it is important to remember that
the designation of drought categories is a process that utilizes
numerous data from a variety of sources on multiple space and time
scales, which includes precipitation, soil moisture, streamflows,
groundwater, various drought indices, and local drought impacts.

Summary of Impacts...
State and local declarations: The Alabama Department of Economic and
Community Affairs (ADECA) Office of Water Resources has no current
drought declarations in effect for the area.

Climate Summary...
Precipitation deficits that began to build in the fall continued
through January. By late January, long term (90 day) precipitation
deficits that started in November were around eight inches across
much of northeastern Alabama. However, the large scale pattern began
to change in February. Heavy rainfall events began to affect the
Tennessee Valley region, but the heaviest precipitation eluded much
of northeastern Alabama until mid to late February. Since then,
precipitation amounts have been one to four inches above normal in
the previous drought-stricken areas. The heaviest rainfall has
occurred in Jackson County, but portions of Lookout Mountain in
DeKalb County still have precipitation surpluses over the last 30
days. On longer timescales out to about three months, however,
generally small precipitation deficits (around one to three inches)
remain in parts of northeastern Alabama. Thus, this is the reason for
keeping the D0 designation in parts of northern Alabama for now.
Also of significance was the unusually warm conditions that occurred
through much of February. Average monthly temperatures for February
for most locations in northern Alabama finished at or near record
warmest. The unusual late winter warmth led to increased evaporation
and increased loss of water from soil and water surfaces than would
have occurred under normal temperature conditions for February.

Precipitation/Temperature Outlook...
Generally below normal temperatures will continue today and tomorrow
before a brief warmup on Saturday into Sunday. Then, temperatures are
expected to average below normal next week. The next weather system
is expected to impact the area on Saturday and Sunday, and may bring
around one to two inches of precipitation to the area.

The 8-14 Day Outlook from the Climate Prediction Center (CPC) valid
for March 15th to 21st slightly favors above normal temperatures and
above normal precipitation for the area.

The Monthly Outlook for March from the CPC indicates no strong
signal regarding temperatures in the Tennessee Valley at this time.
As a result, the outlook indicates equal chances for below, near or
above normal temperatures. For precipitation, the March outlook
indicates that odds are tilted in favor of above normal
precipitation for northeastern Alabama.

Hydrologic Summary and Outlook...
Streamflows across the area experienced significant degradation into
early February, but have since shown recovery in northeastern
Alabama. The latest seven-day average streamflow values are above the
80th percentile on the Paint Rock River, South Sauty Creek and Big
Wills Creek.

According to the CPC, the latest daily soil moisture rankings
indicate that soil moisture values have recovered in the area. As of
March 7th, soil moisture rankings were now in the near normal range
for this time of year. Analyses of deep layer soil moisture from the
North American Land Data Assimilation System and NASA SPoRT also
indicate recovery in deep layer soils up to two meters depth, with
values close to normal for this time of year.

The groundwater well site in Jackson County, which is operated by
the Geological Survey of Alabama, indicates that water levels are
currently closer to values that commonly occur this time of year.
However, these records are only available since 2011.

The outlook for the next week is for continued improved conditions
due to the prospect for more beneficial rainfall this weekend.
Temperatures averaging below normal coupled with higher relative
humidity also suggests less evaporation and lower loss of water from
ground sources than would normally occur.

Next issuance date...
Since drought conditions are no longer present in the area, this
will conclude the regular issuance of Drought Information
Statements by the Huntsville National Weather Service Office. The
next drought statement will be issued if or when drought conditions
return to the area as designated by the U.S. Drought Monitor.
