.PREV DISCUSSION... /ISSUED 229 PM CDT Mon Oct 13 2014/

DISCUSSION...
Winds have shown a slight decrease over the past couple of hours
and should subside much more after sunset with the loss of
boundary layer mixing and a relaxing surface pressure gradient.
Light winds overnight and dry air will provide optimal conditions
for radiational cooling with the Marfa Plateau nearing or dropping
just below freezing tonight. Have gone ahead and upgraded the
watch to a Freeze Warning for tonight so precautions should be
made to protect tender vegetation and animals.

An upper level ridge will move east into the plains and dampen by
mid week bringing a more zonal upper flow and warmer temperatures.
A weak upper trough rounding the crest of the ridge will push a
weak front south into the CWA on Friday bringing a little relief to
the above normal temperatures on Friday. This front will
definitely be dry with all upper support well removed to the
north, but another trough will move into the desert southwest over
the weekend which may bring some rain chances late Sunday or
Monday. Will not introduce PoPs into the forecast so late in the
period but the GFS and ECMWF are showing a nice moisture return
ahead of the trough which could help create at least some
scattered convection.
