UPDATE...
Bumped a few afternoon high temps and added some cirrus.

DISCUSSION...
Visible imagery from GOES 16 showing some cirrus over E TX and we
have gone with mostly sunny verses sunny for many southern zone
groupings. The cirrus is moving to the ESE in the base of the
long wave with a fast short wave ridge over W TX right now.
Morning temperatures are warming at a good pace and minor changes
from low to mid 60s have been applied with everyones favorite add
10 at 10 rule. As of this writing, Shreveport is already 58 with
33 percent RH and very dry air is doing well to heat. The 1031mb
airmass is at Paris TX and will drift overhead tonight while
weakening. Look for the coldest temps East of the ridge axis for
our North and East early tomorrow. /24/
