HYDROMETEOROLOGICAL DISCUSSION
NATIONAL WEATHER SERVICE...WEST GULF RFC...FORT WORTH TX
1109 AM CST FRI DEC 19 2014

                VALID DECEMBER 19 THROUGH DECEMBER 24

...PRECIPITATION CONTINUES OVER NEW MEXICO AND TEXAS OVER THE
NEXT 24 HOURS...

                   ...METEOROLOGICAL DISCUSSION...
An upper level trough is currently moving across the WGRFC area.  This
system is expected to bring widespread precipitation across New Mexico
and Texas through Saturday morning.

Another upper level trough is expected to begin developing over New
Mexico late Saturday and deepen over Texas Monday and Tuesday.  With
this system, precipitation is possible over northern New Mexico and
across north Texas.  By Wednesday, this upper level system is expected
to move east of the WGRFC area.

                    ...PRECIPITATION FORECAST...
For Today into Saturday morning, Mean Areal Precipitation (MAP)
amounts of 0.25 to 2.00 inches are forecast over the Texas Gulf Coast
into southern Louisiana.

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

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

For Monday into Wednesday 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 (44%) 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...
...San Jacinto Basin...
Local heavy rains on Buffalo Bayou will put the river near Sheppards
Drive (BBST2) a few feet over action stage later this afternoon.
Otherewise, the river rises should stay below criteria levels.

...Remainder of 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.

              ...SUPPLEMENTARY GRAPHICAL INFORMATION...
