/issued 337 PM CST MON JAN 25 2016/ (Tonight and Tuesday) The cold front has moved across West Central Texas this afternoon, however the low level cold air advection is lagging behind. For Tuesday, an upper level trough will move into the Southern Plains with a chance of precipitation across much of West Central Texas. 21 (Tuesday night through next Monday) By Tuesday evening, the upper level low is expected to be over southeastern NM or the Upper Trans Pecos of west Texas. With the low going right over this area, will keep the slight chance of precipitation in the forecast for our southwestern areas.
High pressure will shift east of the region overnight and the low level flow will pick up an increasing southerly component. Still could be a little cool across the eastern areas where lows in the lower 40s are expected.

/issued 222 PM CST MON JAN 25 2016/ An upper trough will traverse the region Tuesday and Tuesday night, and along with a colder airmass moving into the region at the surface, result in a mix of rain and snow across the forecast area. Models have come into reasonable agreement that the ua trough will remain open and progressive, so have based precipitation chances on a variety of same. If surface temperatures end up colder in northern Lea and Eddy counties, or heavier precipitation falls in the higher elevations of the Guadalupe and Davis Mountains than currently expected, these areas would be the most likely to see a short fused Winter Weather Advisory from late tonight into Tuesday morning.
ELSEWHERE SCATTERED LIGHT SNOW SHOWERS IN THE HIGH COUNTRY SHOULD GRADUALLY END FROM NORTH TO SOUTH OVERNIGHT AS MID-LEVELS DRY AND STABILIZE IN THE WEAK OF THE PASSING TROUGH.
