.AVIATION...
Very little to talk about on the aviation front as the airspace
will continue to see VFR conditions through the next 24 hours and
beyond. Southwest winds under 10kts for the remainder of the night
will increase slightly with mixing after sunrise Monday morning
with a few higher gusts possible across our NE TX terminal
locations. Otherwise a frontal boundary will be entering our
northwest airspace beyond 12/00z with a wind shift to the
northwest likely at all but the MLU/LFK terminals near or just
before the 12/06z timeframe.

.PREV DISCUSSION... /issued 951 PM CST Sun Dec 10 2017/ 
DISCUSSION...
Light winds, dry air, and mostly clear skies will once again
persist through the overnight hours. A shallow surface trough
passing to the north of the area will result in winds veering to
the southwest across much of the area, and possibly to the
northwest north of Interstate 30. This should keep plenty of dry
air in the region. The 00z KSHV sounding showed a very dry
atmosphere at all levels. 
Given these factors, temperatures tonight will mainly be a 
byproduct of local factors such as terrain, nearby vegetation, and
urban effects. The clear skies and light winds are very good for
radiational cooling. Temperatures have fallen faster than
anticipated in many areas, especially across Deep East Texas and
Central Louisiana, due to the light winds and lower than
anticipated dewpoints. Therefore, temperatures were lowered by a
few degrees across much of the area for tonight, but most
locations are still expected to remain just above freezing.
