   Areas affected...central and eastern Oklahoma into far west-central   
   Arkansas   
      
   Concerning...Heavy snow=20   
      
   Valid 240322Z - 240715Z   
      
   SUMMARY...Moderate to heavy snowfall to increase in coverage through   
   the evening. Rates 1"/hr will be possible.   
      
   DISCUSSION...Snowfall has increased in coverage across portions of   
   central Oklahoma over the last hour, with some reports of moderate   
   snow south of the Oklahoma City metro. Correlation coefficient in   
   recent radar imagery shows a transition zone of primarily snow and   
   sleet south of I-40 from roughly northern Pontotoc County north and   
   east to northern Le Flore County near the Arkansas state line.=20   
      
   Initially, drier air was in place with larger dew point spreads but   
   moistening has been observed with rising dew points and implied   
   saturating profile which will has lead to an increase in snowfall   
   rates over the last hour. Moderate to locally heavy snowfall can be   
   expected to expand in coverage over the next few hours across   
   central/northeastern Oklahoma with occasional rates around 1"/hr.   
      
   Through the evening into early Saturday morning, increasing 850-700   
   mb frontogenesis will increase across a zone from south-central   
   Oklahoma into eastern Oklahoma/western Arkansas across a strong warm   
   advection zone. As moistening continues to occur further east amid   
   this favorable ascent zone, snowfall rates should increase, with   
   likely rates around 1"/hr along the I-40 corridor around 06-09z.
