...Drought has gradually developed this winter across the Texas
South Plains Region...

Synopsis...

Severe Drought (D2) has expanded across most of the Texas South
Plains, north into the extreme southern Texas Panhandle, and east
through the Rolling Plains. Extreme Drought (D3) has enveloped
the northern Rolling Plains centered on Cottle County. This
information is from the latest U.S. Drought Monitor product.

Climate Summary...

This drought began in early October and has continued through the
middle of January. Rainfall the past 110 days has mostly been 10 to
30 percent of normal. The past 80 days since the first of
November have been particularly dry with many locations not
receiving any rain. This is the dry season over the southern
plains, of course, yet this dry spell is particularly long and
deep. A La Nina over the Tropical Pacific ocean is responsible for
a split flow weather pattern along the U.S. west coast blocking
Pacific energy and moisture from our area as well as much of the
southwest. Weather systems and available moisture have been
anemic.

Precipitation/Temperature Outlook...

With La Nina peaking, this will be a dominant signal guiding weather
patterns the next several months. Normal to above normal temperatures
and below normal precipitation are expected the remainder of winter
and early spring, interspersed with brief cold, mostly dry spells.
Thereafter, some weakening of La Nina is possible. Equal chances
for dry, normal, and wet conditions along with continuing above
normal temperatures are expected for late spring.

Fire Weather Impacts...

Areas of abundant cured grasses remain from last summers growth,
but new growth has been stunted by winter cold and also lack of
rain. This will help carry fire on windy days. Any upcoming windy,
dry, and warm period will bring a risk of elevated to critical
fire weather conditions.

Agricultural Impacts...

Winter wheat that already has been impacted by lack of rain, may
suffer additionally by occasional bouts of cold. Irrigation needs
will continue for rangelands still being used for forage while
cattle may be pulled from dryland pastures.

Hydrologic Summary and Outlook...

In general, compared to recent years, reservoirs were at fair
storage levels, though most showing recent decline. The following
