Aviation... 
IFR conditions are expected at the terminals tonight and Monday 
morning due to widespread low clouds. Radar trends are indicating 
that precipitation is moving northeast at a good clip across west central 
Texas. Looks like the best coverage of precipitation will be across the Big 
Country during the early evening hours...with the kabi terminal 
possibly seeing another burst of snpl. Also...warming low level 
thermal profiles will change the precipitation type to mainly -fzra by 02z 
Monday at the kabi terminal. Only isolated to scattered rain showers are expected to 
affect the southern terminals tonight. Most of the precipitation will be 
over Monday...with mainly VFR conditions after 20z Monday.

Short term... 
the first shortwave that originated from Mexico resulted in about a 
half to an inch of snow across a large part of wc Texas today. This 
wave will continue to track off to the northeast this evening. The 
second shortwave trough was already spreading areas of freezing rain 
and sleet across far West Texas. This system will bring more sleet 
into the Winter Weather Advisory area through midnight. The nam12 
soundings continue to support sleet through midnight mainly along 
and north of a line from Mertzon to San Angelo to Eden to Brownwood. 
After midnight...the column quickly warms and the sleet becomes 
mixed with rain with a gradual changeover to all rain. As 
temperatures continue to rise south of this line...expect most of 
the winter precipitation to become liquid around 6 PM as temperatures rise 
above freezing. 


For this reason...the Winter Weather Advisory will continue through 
at least midnight for the area north of a line from Mertzon to San 
Angelo to Eden to Brownwood. South of this line will extend the 
advisory until 9 PM. The precipitation should end by Monday 
morning as a drier southwest to west wind overtakes the region. 
Look for temperatures warming into the 60s with plenty of sunshine on 
Monday. 


Long term... 
continued warm up Tuesday and Wednesday as surface low develops 
in the Panhandle and moves across Oklahoma. A slight chance of 
showers Tuesday night and Wednesday morning...mainly along and 
east of a Brownwood to Sonora line...as a weak surface trough 
moves through west central Texas and low level moisture east. A 
cold front pushes through Wednesday night as the surface low 
continues its movement northeast. Only a slight cool down 
Thursday and Friday as the origins of the cold front are from the 
Pacific northwest. 


Both ec and GFS models track another upper low from Baja California 
California Thursday...across Texas this weekend. Ec is more 
progressive with the system...pushing it east by Saturday 
morning. GFS is holding onto a slower Saturday solution. Will 
give a nod to the more consistent GFS solution and continue a 
chance of showers Saturday and Saturday night.
