    Mesoscale Discussion 1706

    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.
