                   ...METEOROLOGICAL DISCUSSION...

A ridge of high pressure will continue to dominate most of the
WGRFC region through the weekend.  A cold frond will approach
fromfrom the plains early in the week increasing chances for
precipitation across easter Colorado and New Mexico and the
western third of Texas.

The tropics continue to remain very active.  Hurricane Maria
is now a Category 3 storm on the Saffir-Simpson Hurricane Wind Scale
and continues to move towards the northwest at 9 mph. At this
time, this system is not expected to impact any portion of
the WGRFC region.

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

For Friday into Saturday morning, MAP amounts of 0.25 to 1.0 are
forecast across eastern New Mexico.

For Saturday into Sunday morning, MAP amounts up to 1.5 inches are
forecast a ross eastern New Mexico.

For Sunday into Tuesday morning, MAP amounts of 0.5 to 2 inches are
forecast across eastern Colorado, eastern New Mexico and the western
third of Texas.

The latest U.S. Drought Monitor for Texas shows the area considered
to be abnormally dry is around 21%, and only 3% of Texas is
experiencing moderate drought conditions. In New Mexico, none of
the state is experiencing abnormally dry conditions.
