AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
412 AM CDT Mon Jul 21 2014

.DISCUSSION...
Above normal temperatures are expected the next seven days
as an upper level ridge of high pressure builds across the
southern Rockies eastward to the southern Plains. At the
surface a lee trough is forecast to remain in place across
extreme west Texas/eastern New Mexico many days through the next
week. More very intense heating along the surface trough with
upslope flow in the mountains combined with trapped mid level
moisture underneath the upper ridge should generate mainly
afternoon and evening isolated to scattered thunderstorms across
the Guadalupe and Davis Mountains, southeast New Mexico Plains,
portions of the upper Trans Pecos through Tuesday. Weak steering
flow and instability could produce locally heavy rainfall both
today and Tuesday afternoon and evening. High temperatures once
again will be around 105 degrees along the Rio Grande river from
southern Terrell county westward to the Big Bend and Presidio
valley. Will issue a heat advisory through 12Z Wednesday morning
due to high temperatures expected to be at or above 105 degrees
along the Rio Grande with low temperatures expected to be 75 to
80.

Beyond Tuesday the upper high center is forecast to strengthen
and mid level moisture will become limited. Precipitation chances
do not appear high enough at this time to mention in the weather
grids Wednesday through next Monday. Temperatures will continue
to be much above normal. The heat advisory may need to be expanded
both in time and location.
