    Mesoscale Discussion 1739
    NWS Storm Prediction Center Norman OK
    1147 PM CST Thu Dec 27 2018

    Areas affected...Central and eastern New Mexico

    Concerning...Heavy snow

    Valid 280547Z - 281145Z

    SUMMARY...Areas of heavy snow are expected across the area through
    the early morning hours. 1+ inch/hr rates are expected, with up to 2
    inch/hr rates possible in the higher elevations.

    DISCUSSION...An upper-level trough continues to deepen across the
    southwestern CONUS, with a 100+ knot 300 mb jet streak approaching
    the area from the west. Simultaneously, sfc-850 mb easterly cold air
    advection has been cooling low-level profiles, with temperatures
    quickly dropping below freezing at the surface. In addition, the
    westward moving boundary of the colder low-level airmass is
    fostering strong low-level convergence. Upper-level divergence
    associated with the left-exit region of the aforementioned jet
    streak overlapping areas of strong 925-850 mb frontogenesis is
    currently promoting very strong, deep-layer ascent.

    A relatively deep (800+ m), nearly saturated dendritic growth zone
    is present across these areas experiencing strong ascent, suggesting
    heavy snow potential will be a concern within the next few hours,
    through early morning. Latest ensemble model guidance also suggests
    heavy snow potential across central and eastern portions of New
    Mexico through sunrise, with 1+ inch/hr rates likely in the lower
    elevations and 2+ inch/hr rates in the higher terrain.
