.PREVIOUS DISCUSSION... /Issued 1030 AM CST Sun Dec 18 2016/

DISCUSSION...Strong CAA continues across the CWA this morning
with most areas having temps fallen into the 30s. Core of
strongest winds at 925mb have shifted south and east of the area
with a gradual downward trend in wind speeds expected through the
remainder of the day. As such...I have cancelled the wind
advisory. Did extend the Wind Chill Adv into early afternoon for
the northern Coastal Bend as wind chill values of 25 degrees or
slightly lower are expected across this area for a few more hours.

Primary forecast changes were to lower max temps by about a
category today where cloud cover is expected to remain socked in.
Areas of the Brush Country may mix out this afternoon...where high
temps should be the greatest. Farther east...some breaks in the
overcast may occur.

Looking ahead to the afternoon forecast package...expect Freeze
Warnings and Wind Chill Advisories to be issued for tonight for at
least portions of South Texas.

MARINE...Very dangerous marine conditions persist offshore with
wave heights ranging from 12 to 17 feet over the past few
hours...along with continued gales. A general downward trend in
wind speeds are expected through the afternoon...but strong north
flow should persist into tonight. Gale Warning continues for open
Gulf Waters and Small Craft Advisory for area bays/waterways.
