Area Forecast Discussion
National Weather Service Midland/Odessa TX
459 AM CST FRI NOV 20 2015


The latest Aviation Discussion is included below.



VFR conditions will prevail through this evening, but a strong cold
front will move south through the area tonight.  Blowing dust may
drop visibility to MVFR at some area terminals, but will not include
any reduction at this time since it will be so late in the forecast
period.  Gusty northerly winds will persist through most of the day


.PREV DISCUSSION... /issued 342 AM CST FRI NOV 20 2015/

Major weather changes headed for the region this weekend as we see
the coldest air of the season so far. Before we see that though,
temperatures will warm significantly this afternoon amid downslope
southwesterly winds and sfc pressure falls. Meanwhile, a shortwave
will drop south across the Northern Plains later today bringing with
it a strong cold front. This front is expected to arrive late
tonight and quickly clear the CWA by sunrise Saturday. Pressure
gradient and pressure rises are quite impressive behind the front.
Given this, expect advisory level winds over most of the area for at
least a few hours early Saturday morning. High winds still look
likely at Guadalupe Pass as well so will upgrade to a High Wind
Warning there and will opt to issue a wind advisory for the rest
of the region. The strong winds will likely bring some patchy
blowing dust into the area so will include in the forecast through
Saturday morning.

After a very cool Saturday our next concern is the first hard freeze
of the season expected Sunday morning. Light winds, clear skies, and
dewpoints well into the teens will allow for ideal radiational
cooling. This will be the first hard freeze of the season for many
as temperatures fall into the 20`s and even teens. We have issued a
Freeze Watch for all locations that have not had a hard freeze yet
this year. This includes much of the Permian Basin, Trans Pecos, and
Big Bend.

Flow becomes more zonal early next week which should allow for a
nice warm-up with temperatures rising back above normal. A weak
disturbance and moisture from Tropical Storm Rick (great name by the
way) may bring bring a chance of showers to the Big Bend Tuesday.
Southwesterly flow aloft will increase around the Thanksgiving
holiday, bringing a chance for precip. Temperatures look to be well
above freezing so precip should remain all liquid.
