Discussion...
cold air, low clouds and areas of freezing drizzle and freezing
fog are stubbornly hanging in across mainly portions of the plains
of southeast New Mexico and West Texas. Expecting the lower clouds
to continue tonight in these areas with slowly rising temperatures
due to the surface high slowly pushing off to the east. With
residual snow cover, it still appears that temperatures will stay
at or below freezing across the extreme western Low Rolling Plains
and extreme eastern Permian Basin. In addition forecast soundings
are indicating that moisture should remain deep enough for areas
of freezing drizzle to continue. Will continue the Winter Weather
Advisory overnight through mid Sunday morning for the aforementioned
area as a result. Further west across the central and western
Permian Basin and Lea County New Mexico temperatures will either
rise above freezing and or the moisture depth will not be enough
for significant ice accumulations. For these areas will expire the
Winter Weather Advisory at 6 PM CST, but issue a Special Weather
Statement for overnight and mention the lighter accumulations
expected.

For Sunday will lower high temperatures considerably especially
across the plains based on the new NAM and European model (ecmwf) guidance
indicating another surge of cooler air invading from the northeast.
The cooler air will continue to push southwest into the forecast
area Sunday night and Monday. Precipitation chances will increase
again as the upper level flow backs ahead of the next Pacific
system with isentropic lift developing. Surface temperatures
may be cold enough to support a chance of freezing rain
Sunday night and early Monday across the northern Permian Basin
and Lea County New Mexico. By Monday afternoon and Monday night
temperatures should be warm enough for all liquid across West
Texas and southeast New Mexico.

Precipitation chances will continue across a good chunk of
the forecast area Tuesday and Wednesday as the aforementioned
system approaches. Yet another surge of colder air is expected
by Wednesday with some light snow possible. The precipitation
could continue (some snow) into Thursday if the slower European model (ecmwf) is
correct.

Beyond next Thursday guidance handles the upper level low
differently so kept dry for now with slowly moderating
temperatures.
