...Drought conditions persist across portions of West Central


The latest U.S Drought Monitor (USDM), released on May 3rd,
indicates that severe drought (D2) conditions still exist over
the northwestern Big Country. In addition, D2 conditions have
developed across southern portions of the northern Edwards
Plateau, southeastern Kimble County, eastern Concho County,
extreme southwestern Coleman County and extreme northwestern
McCulloch County. 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 May 4th, countywide outdoor burn bans were supported in
Throckmorton, Fisher, Jones, Nolan, Callahan, Coke, Tom Green,
Concho, San Saba, Schleicher, Menard, Mason, and Sutton counties.

Agricultural Impacts...

Very little rain and strong winds caused decreasing subsoil
moisture across the region. Pasture forages were drying up and
grasses were showing no growth. Most wheat was baled for hay as
the grain outlook was poor. Livestock was in mostly poor
condition and supplemental feeding continued.

Climate Summary...

On average, one quarter to one half of an inch of rain fell
across the region during the month of April. A few locations
received up to an inch. Therefore, most of the area saw below
normal rainfall. 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 5.39 inches of rainfall, which is 0.63 inches
below normal.

San Angelo received 3.39 inches of rainfall, which is 2.02 inches
below normal.

Junction received 2.44 inches of rainfall, which is 4.85 inches
below normal.

Precipitation/Temperature Outlook...

According to the Climate Predication Center (CPC), La Nina has
continued to weakened over the past couple of months and a
transition into ENSO-neutral conditions are expected this month.
ENSO-neutral conditions are then likely to continue through the
summer. Once the transition occurs to ENSO-neutral, equal chances
for dry, normal, and wet conditions along with continuing above
normal temperatures will be expected into the summer.

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 above
normal temperatures in both the 6-10 day and 8-14 day periods.
These outlooks were updated on May 4th.

The latest U.S. Seasonal Drought Outlook for April 19 through
July 31 (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.
