HYDROMETEOROLOGICAL DISCUSSION

                VALID DECEMBER 18 THROUGH DECEMBER 23

...PRECIPITATION CONTINUES OVER NEW MEXICO AND TEXAS OVER THE
NEXT COUPLE OF DAYS...

                   ...METEOROLOGICAL DISCUSSION...
An upper level trough along the Pacific coast is deepening as it
moves to the east.  This system is expected to continue to generate
upper level disturbances that will bring widespread precipitation
across New Mexico and Texas through Saturday morning.

For New Mexico, another trough will pass eastward today over
the state leaving additional snow at higher elevations by the time
it leaves the state.  The most favorable areas for precipitation
remain focused on the central parts of the state.

For Texas, light scattered showers and drizzle are slowly moving east
with light rain remaining possible mainly for the I-35 corridor and
points east. The Hill Country and points to the south including Corpus
Christi and points east northeast to the Louisiana border are expected
to receive the heaviest amounts into Friday. The following 24 hours
from Friday into Saturday, the eastern third of Texas will be the
focus of the next round of precipitation. This period may see
rainfall totals in the 1-3 inch range.

The next potential for precipitation is Monday and Tuesday over
north central New Mexico and over the northern portions of Texas.

                    ...PRECIPITATION FORECAST...
For Today into Friday morning, Mean Areal Precipitation (MAP)
amounts of 0.25 to 2.00 inches are forecast for central and
southeastern Texas with the heaviest amounts hugging the coast from
Victoria to Beaumont.

For Friday into Saturday morning, MAP amounts of 0.25 to 2.00 inches
are forecast for the eastern third of Texas from the I-35 corridor
east to the Louisiana border.  Amounts increase in intensity from
west to east.

For Saturday into Sunday morning, no significant MAP amounts are
forecast for the WGRFC area.

For Sunday into Tuesday morning, no significant MAP amounts are
forecast for the WGRFC area.

Moderate or worse drought conditions continue to be observed over
parts of New Mexico and Texas.  In Texas, about half the state is
experiencing moderate or worse drought (43%) and 10% has extreme to
exceptional drought conditions. In New Mexico, nearly two thirds of
the state is experiencing moderate or worse drought (65%) and 4% has
extreme to exceptional drought conditions. Soils are generally dry
enough such that forecast rainfall will generate mostly minor runoff.

                     ...HYDROLOGIC DISCUSSION...
...WGRFC Basins...
Rainfall amounts have been slow and steady replenishing much needed
soil moisture. Rainfall over the next day or so is expected to
continue to provide beneficial moisture. No flooding is expected
through the forecast period.
