Area Forecast Discussion
National Weather Service Midland/Odessa TX
849 PM CST Sat Feb 18 2017


Sat imagery shows high clouds increasing across West Texas and
Southeast New Mexico, which will inhibit rad cooling overnight.
00Z NAM forecast soundings suggest overnight mins can be raised a
couple of degrees. In addition, area radars show returns
increasing out west, and some -SHRA may make it into far western
zones before 12Z. Thus, we`ll do an update to add this, bump up
overnight mins, and adjust other parameters as necessary. Updates
out shortly.

PREV DISCUSSION... /issued 152 PM CST Sat Feb 18 2017/

Upper ridge over the area today will give way to approaching upper
trough moving off the West Coast.  This trough develops into a cut
off low and by tomorrow centered near the 4 corners region.  This
trough will open up and slowly push east Sunday with the ridge
beginning to return by late Monday.  On Wednesday the next upper
trough moves off the coast and quickly moves east crossing the
Rockies Thursday.

Temperatures will be warm this week with highs generally in the 70s
and may hit 80s by midweek.  The normal high temperature for this
time of year in the Permian Basin is 63 so the week looks to be well
above normal.  A front late in the week will knock temps back down
into the 60s.

The development of a leeside trough will turn surface flow back to
the south with the return of low level moisture expected.  Current
dewpts are in the 20s and 30s as of 18z... these should increase to
the 40s to low 50s across the east overnight.  Could see some patchy
fog over the east tomorrow morning.  A dryline is expected to
develop tomorrow and push the moisture east ahead of it.  There is a
low chance of storms developing on the dryline tomorrow over the
eastern Permian Basin and Lower Trans Pecos... but most of these
will be east of the area.  Could see strong to severe storms for
North and Central TX tomorrow.

A west wind will kick in tomorrow behind the dryline.  Should be
windy through GDP but stay below high wind criteria... did bump up
speeds a bit in the afternoon.  Could have some fire wx concerns
west of the dryline
