AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
1132 PM CST Mon Dec 9 2013

.AVIATION...
06Z TAF issuance
Drier air filtering in from the northwest and north has eroded low
clouds.  However, redevelopment of low clouds and fog will likely
occur as the dry air will not intrude too far south overnight.
Therefore, have kept an IFR ceiling/MVFR visibility at KFST, while
the rest of the TAF sites will likely see IFR and MVFR visibilities
occur as fog forms under the clearing sky.  IFR ceilings will also
likely form as the fog becomes better established 10/12Z to 10/15Z.
All TAF sites should be VFR by 10/16Z and after as heating
commences.

UPDATE...

Update to cancel the Winter Weather Advisory, and tweak sky
coverage, dewpoints and low temperatures.

DISCUSSION...

As of 10/03Z, low clouds continue to erode and visibilities are
improving from northwest to southeast as fog dissipates due to dry
air spreading into the region from New Mexico and the Texas
Panhandle.  Unlike a couple of hours ago, think the instance of
freezing drizzle will be very limited over the western Low Rolling
Plains as a result.  Therefore, will cancel the Winter Weather
Advisory.

Although dry air will continue to push southeastward overnight,
clearing skies will likely allow areas along and south of a Snyder,
Midland/Odessa, Balmorhea line to see fog since low level moisture
will be higher in these areas, and the dry air will take most of the
night to push this far south.  Therefore, will leave patchy freezing
fog in the forecast for these locales overnight.  Adjusted some
temperatures down due to the clearing sky and dry air influx,
especially over the north and west.  Otherwise tweaked sky and
dewpoint grids.  Will send an update shortly for these changes.
