MESOSCALE DISCUSSION 0001
   NWS STORM PREDICTION CENTER NORMAN OK
   1210 PM CST THU JAN 03 2013
   
   AREAS AFFECTED...SRN NM THROUGH SWRN TX
   
   CONCERNING...HEAVY SNOW 
   
   VALID 031810Z - 032315Z
   
   SUMMARY...OCCASIONAL MODERATE TO HEAVY SNOW WITH RATES LOCALLY UP TO
   1 INCH PER HOUR IS EXPECTED TO PERSIST INTO THE EARLY EVENING ACROSS
   SRN NM INTO WEST TEXAS. TENDENCY SHOULD BE FOR HEAVIER SNOW TO
   DEVELOP FARTHER SWD TOWARD THE BIG BEND AREA OF SW TX LATER THIS
   AFTERNOON OR EVENING.
   
   DISCUSSION...AREAS OF SNOW WITH EMBEDDED BANDS OF LOCALLY MODERATE
   TO HEAVY SNOW CONTINUES WITHIN A BROAD ZONE OF WARM ADVECTION FROM
   SRN NM THROUGH WRN AND SWRN TX. THE PRECIPITATION HAS INCREASED IN
   COVERAGE AND INTENSITY THROUGH THE MORNING IN ASSOCIATION WITH A
   SHORTWAVE TROUGH MOVING ENEWD THROUGH NRN MEXICO. THE 12Z RAOB FROM
   EL PASO INDICATED AN UNSTABLE LAYER BETWEEN 600 AND 400 MB
   SUGGESTING SOME CONVECTIVE ENHANCEMENT IS LIKELY OCCURRING. AN UPPER
   JET STREAK LOCATED OVER NRN MEXICO WILL SHIFT NEWD TOWARD THE BIG
   BEND THIS EVENING. THIS FEATURE WILL CONTRIBUTE TO INCREASING ASCENT
   WITHIN DENDRITIC GROWTH LAYER...LIKELY AUGMENTING SNOWFALL RATES
   FROM THE MOUNTAINS OF SWRN TX INTO THE BIG BEND AREA LATER THIS
   AFTERNOON AND EVENING.
