                VALID DECEMBER 14 THROUGH DECEMBER 19

  ...PRECIPITATION RETURNS TO DEEP SOUTH TEXAS LATE TONIGHT...

                   ...METEOROLOGICAL DISCUSSION...
A slight warming trend can be expected this work week across
the WGRFC area as temperatures continue to rebound to near
average. Late this evening through the overnight hours, showers
and thunderstorms are expected to develop over Deep South Texas,
ahead of an approaching cold front and upper level disturbance.
This activity is expected to continue through the tomorrow
afternoon. By Saturday, the focus for showers and thunderstorms
is forecast to shift towards portions of East Texas, as the
upper level disturbance quickly moves off towards the east.

Although this precipitation will bring some relief to portions
of the state, unfortunately the drought is expected to
continue. No significant rainfall or flooding is expected the
next 5 days.

                    ...PRECIPITATION FORECAST...
For Today into Friday morning, Mean Areal Precipitation (MAP)
amounts of up to 0.50 inch are forecast for portions of
Deep South Texas and northern Mexico.

For Friday into Saturday morning, MAP amounts of up to 0.50 inch
are forecast for portions of Deep South Texas and northern Mexico.

For Saturday into Sunday morning, MAP amounts of up to 1.00 inch
are forecast for portions of Southeast and East Texas.

For Sunday into Tuesday morning, MAP amounts of up to 0.50 inch
are forecast for portions of Southeast and East Texas.

The latest U.S. Drought Monitor for Texas shows the area considered
to be abnormally dry is around 72%, with around 37% of the state
experiencing moderate drought and 11% in severe drought.  In New
Mexico, 53% of the state is having abnormally dry conditions, with
16% in moderate drought conditions (over the far western portions).
With the dry weather this fall, a large portion of the WGRFC
forecast area is experiencing some type of abnormally dry or drought
condition.

                     ...HYDROLOGIC DISCUSSION...
...WGRFC Basins...
All rivers across the WGRFC area are at or below normal flows and
