...LIGHT RAINFALL IN EASTERN TEXAS THIS WEEKEND. SNOW IN
COLORADO...

                  ...METEOROLOGICAL DISCUSSION...

Surface high pressure in eastern Texas is keeping things dry this
Saturday morning. As high pressure departs to the east this evening,
some light showers can be expected to develop for eastern and
southeastern Texas. Meanwhile snow will be developing along the
western slopes in Colorado. Generally light rain will continue Sunday
in eastern and southeastern Texas while snowfall temporarily
decreases in Colorado. A weak upper level disturbance and associated
cold front will be responsible for the weekend precipitation.

Next week, Texas will be mostly dry but will have a chance for
occasional light rainfall particularly near the coast and in eastern
Texas. Periodic snowfall is expected in western Colorado throughout
the coming week.

                    ...PRECIPITATION FORECAST...
For Today into Sunday morning, Mean Areal Precipitation (MAP)
amounts of 0.25 to 0.5 inch are forecast for southwestern Colorado.
Lesser MAP amounts are forecast for portions of eastern and southern
Texas.

For Sunday into Monday morning, MAP amounts of up to 0.25 inch are
forecast for portions of eastern and southern Texas and for portions
of southern Colorado and far northern New Mexico.

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

For Tuesday into Thursday morning, MAP amounts of 0.25 to 0.5 inch
are forecast for southwestern Colorado.

The rainfall late last week into the weekend significantly
improved the drought conditions across the eastern sections of
the WGRFC area. In Texas,the area considered to be abnormally
dry is now 18%. Also, 5% of Texas is experiencing moderate drought
conditions and only 0.65% remains in severe drought. There were no
changes for New Mexico with around 54% of the state experiencing
abnormally dry conditions,with 5% remaining in moderate drought.

                     ...HYDROLOGIC DISCUSSION...
...WGRFC Basins...
Some residual flooding effects remain from the last round of rainfall
across the WGRFC area of responsibility.  Minor flooding
continues in the lower Guadalupe basin near Bloomington (DUPT2).
Some out of bank levels continue in the lower Neches and San Antonio
basins.

All other affected rivers are at or near normal levels. Heavy
rainfall is not anticipated over the next five days, so renewed rises
are not expected.
