Aviation... 
the weak cold front was moving to near kuts at 0445z and is 
expected to become nearly stationary along a line from near 
Livingston to Brenham between 06z and 09z. The nam12 and hrr 
models both agree with good chances for at least MVFR and possibly 
IFR conditions to develop between 07z and 10z from kcxo southward 
to the coast. These conditions will lift by 14z or 15z with VFR 
expected after 16z.

Discussion... 
at 01z...a weak cold front extended from kshv to kpsn to kerv. The 
front was not making much progress to the south and pressure rises 
behind the boundary are rather meager so not expecting much more 
of a push south overnight. The rap brings the wind shift to a 
Caldwell to Onalaska line by 10z. The front will become a bit 
diffuse during the morning with onshore winds reestablished 
areawide by 17z. 00z soundings show precipitable waters  between 1.4 and 1.6 
inches with strong capping at crp and a slightly weaker cap at 
lch. Radar showed a few weak echoes so added isolated showers to 
the grids. Most areas will likely remain dry. Stronger winds just 
off the surface will favor low ceilings overnight but the T/dew point gap is 
narrowing so can't rule out some patchy fog especially once surface 
winds decouple. Rest of the forecast looks on track. New zones out by 
900 PM. 43
