Areas affected...extreme southeast NM into west TX

Concerning...Heavy snow 

Valid 131649Z - 132015Z

SUMMARY...An area of mainly light to moderate snow with heavier snow
bursts mixed in will affect portions of extreme southeast NM into
west TX the next few hours. Combined with strong northwesterly
winds, visibility may become greatly reduced at times.

DISCUSSION...Cold temperatures are quickly filtering southward into
the southern High Plains behind a cold frontal passage. Rain has
turned to snow in several locations from HOB in southeast NM to the
Midland-Odessa vicinity in west TX. A very strong surface pressure
gradient across the region is resulting into sustained winds around
25 mph with higher gusts. Recently, ODO reported heavy snow with MAF
and MDD reporting light to moderate snow with lowered visibility to
around 2-3 miles. While snow rates may briefly be heavy, combined
with strong winds, visibility will remain lowered and could change
quickly over short distances. 

The area of precipitation will continue to track eastward into the
afternoon and may change to a mix of rain/snow or all rain further
east across central TX where temperatures may be slower fall to near
freezing until later in the afternoon or early evening.
