DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE SAN ANGELO TX
1104 AM CDT Tue Apr 10 2018

...Drought conditions persist across portions of west central
Texas...

Synopsis...

The latest U.S Drought Monitor (USDM), released on April 5th,
indicates that severe drought (D2) conditions only exist over the
northwestern Big Country. Extreme drought (D3) conditions
persisted in the northwest corner of Haskell county.

Summary of Impacts...

Fire Weather Impacts...

Warmer than normal temperatures combined with periods of dry and
gusty winds enhance critical fire weather conditions. Fire danger
can change from day to day as wind and relative humidity vary.
The Texas Forest Service advises to watch out for key weather
thresholds of winds above 15 mph and relative humidity values
below 25 percent. When these thresholds are exceeded, expect the
fire danger will be elevated.

As of April 10th, countywide outdoor burn bans were supported in
Throckmorton, Fisher, Callahan, Tom Green, Concho, Schleicher,
Menard, Mason, and Sutton counties.

Agricultural Impacts...

Subsoil moisture improved somewhat across the region, but still
remained very dry. Winter wheat reached completion, but the crop
was still behind. Field preparation was ongoing for the cotton
crop. Livestock remained in mostly fair condition and supplemental
feeding decreased. Stock tanks and ponds levels have shown some
improvement, but needed more runoff water to fill before summer.

Climate Summary...

On average, 1-2 inches of rain fell across the region (lower
amounts across the western half of the area, which is where the
worst drought conditions exist) during the month of March,
however this still was below normal. Hence, we are still below
normal for the year and given that the 2017 calendar year ended
with a precipitation deficit, drought conditions persisted.

Since the beginning of January, 2018, the following precipitation
amounts have been recorded:

Abilene received 3.88 inches of rainfall, which is 0.64 inches
below normal.

San Angelo received 2.57 inches of rainfall, which is 1.60 inches
below normal.

Junction received 2.05 inches of rainfall, which is 3.25 inches
below normal.

Precipitation/Temperature Outlook...

According to the Climate Predication Center (CPC), La Nina has
weakened over the last couple of months, but will persist for the
next month or so before transitioning into ENSO-neutral.
Therefore, this will continue to be the main driver in weather
patterns over the next couple of months. Overall, above normal
temperatures and below normal precipitation are expected for the
remainder of spring and into early summer. If indeed the transition
occurs to ENSO-neutral, equal chances for dry, normal, and wet
conditions along with continuing above normal temperatures will be
expected for late spring.

Across west central Texas, the CPC outlook shows increased
chances of below normal precipitation in both the 6-10 day and
8-14 day periods. The outlook shows increased chances of near or
above normal temperatures in the 6-10 day period, with above
normal temperatures in the 8-14 day period. These outlooks were
updated on April 9th.

The latest U.S. Seasonal Drought Outlook for March 15 through June
30 (issued by the CPC), shows that drought conditions will likely
persist across west central Texas.

Hydrologic Summary And Outlook...

According to the U.S. Geological Survey (USGS), gaged streamflows
across most of west central Texas are normal to below normal for
this time of year.
