DISCUSSION...

The remainder of the snow is moving east of the area with freezing
temperatures across most of the CWA except south of the Davis
Mountains, portions of the Lower Trans Pecos, and along the Rio
Grande. The precipitation is expected to be out of the area by this
evening, and the rest of the forecast is dry. The surface high
will remain near the area overnight and skies will begin to clear.
Overnight lows tonight will be allowed to plummet into the upper
teens in northern Lea County to around 32 degrees around the Rio
Grande. There is a Hard Freeze Warning in effect for the southern
Permian Basin and Lower Trans Pecos for a hard freeze and along
the Rio Grande for a freeze.

Surface winds will return to the south by Friday afternoon allowing
for temperatures to warm up into the 40s for most of the area.
Mostly zonal flow will be in place over the weekend with surface
winds become elevated out of the southwest to west with a surface
trough developing.  These conditions will allow for temperatures to
warm up into the 50s and 60s for Saturday and into the 60s and 70s
for most places on Sunday.  The GFS and ECMWF both show a weak cold
front moving into the area on Monday resulting in temperatures
cooling into the 50s for the northern Permian Basin.  The models
then show another, stronger cold front moving into the area Tuesday
night which will result in temperatures cooling into the 40s and 50s
for the CWA except along the Rio Grande on Wednesday.
