HYDROMETEOROLOGICAL DISCUSSION
NATIONAL WEATHER SERVICE...WEST GULF RFC...FORT WORTH TX
1019 AM CST SAT JAN 20 2018

                 VALID JANUARY 20 THROUGH JANUARY 25

...A WARM-UP IN STORE WITH NO FLOODING EXPECTED THROUGH THE END OF
THE WEEKEND...

                   ...METEOROLOGICAL DISCUSSION...

A warm-up is forecast as the arctic air is being replaced across the
WGRFC area over the next few days.  Drought conditions are expected
to continue through the end of the month with very little
significant precipitation forecast over the next week.

A ridge of high pressure will bring dry weather to most of the
region today through tomorrow. Thereafter, a new low pressure
system is forecast to move across the western U.S. and will begin
to bring rainfall to portions of Northeast and East Texas by late
tomorrow/early Monday. The forecast rainfall will not be enough
to affect mainstem rivers. Temperatures will rebound across the
WGRFC area this weekend into next week.

                    ...PRECIPITATION FORECAST...
For Today into Sunday morning, no significant Mean Areal
Precipitation (MAP) amounts are forecast for the WGRFC area.

For Sunday into Monday morning, MAP amounts of up to 1.50 inch
are forecast for portions of Northeast and East Texas.

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

For Tuesday into Thursday morning, MAP amounts of up to 0.50 inch
are forecast for portions of Deep South Texas.

The latest U.S. Drought Monitor for Texas shows the area considered
to be abnormally dry is around 79%, with around 41% of the state
experiencing moderate drought and 16% in severe drought. In New
Mexico, 100% of the state is having abnormally dry conditions, with
87% in moderate drought conditions and 12% in severe drought. The
precipitation forecast the next 5 days will not be heavy enough to
produce significant runoff.

                     ...HYDROLOGIC DISCUSSION...
...Sabine Basin...
Higher flows from Toledo Bend are being generated due to cold
weather demands. Info released daily after 10AM until further
notice.

...Remainder of WGRFC Basins...
Area rivers remain below criteria and are expected to continue
with at or below normal flows for the next 5 days, as no
significant rainfall is expected during this time frame.
