HYDROMETEOROLOGICAL DISCUSSION
NATIONAL WEATHER SERVICE...WEST GULF RFC...FORT WORTH TX
918 AM CST FRI FEB 24 2017

                  VALID FEBRUARY 24 THROUGH MARCH 1

...DRY CONDITIONS WILL DOMINATE OVER THE NEXT FEW DAYS WITH
INCREASING RAIN CHANCES BY LATE WEEKEND...

                   ...METEOROLOGICAL DISCUSSION...

A ridge of high pressure is forecast to continue to build over
Texas bringing dry weather conditions to most of the WGRFC area.
The ridge will continue to bring dry weather over the next few
days. The only chance for light precipitation will be over
eastern Texas later this weekend.

As of Friday morning a front was passing through the WGRFC
forecast area. The atmosphere will be so dry the front will pass
without producing any rainfall. On Friday a strong zonal flow of
air is forecast to develop across the WGRFC area. This zonal flow is
very dry, thus no rainfall is forecast from Friday through Saturday.

Rain chances do increase towards the end of the weekend with a
return of onshore flow from the gulf interacting with an
approaching dry line. Preciptation amounts will be light and are not
expected to cause any flooding concerns.

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

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.

Rainfall continued to improve the soil moisture conditions across
much of Texas. The last U.S. Drought Monitor for Texas showed the
area considered to be abnormally dry was at 8.4%.  Also, 2% of Texas
was experiencing moderate drought conditions and  less than 1% was in
severe drought. In New Mexico the drought monitor shows around 13% of
the state experiencing  abnormally dry conditions, with 2.5%
remaining in moderate drought. The rainfall forecast the next few
days will not produce new or additional runoff over the WGRFC area.

                     ...HYDROLOGIC DISCUSSION...
...WGRFC Basins...
Rivers in Texas continue to recede after responding to the early week
rainfall.   Out of bank flows continue in portions of the Brazos,
Trinity, Guadalupe, San Antonio, San Bernard, and San Jacinto basins
with minor flooding in the upper Trinity below lake Bridgeport and the
lower Guadalupe near Dupont.   No significant rainfall is forecast
across WGRFC in the next 5 days.
