   SUMMARY...Moderate to locally heavy snow rates are possible early   
   this morning.   
      
   DISCUSSION...A large precipitation shield is spreading across parts   
   of MO/IA and western IL early this morning, within the warm conveyor   
   region of a surface cyclone centered over southwest KS. Strong, deep   
   ascent being driven by both low-level warm advection and favorable   
   upper-level difluence will maintain widespread precipitation through   
   the early-morning hours.=20   
      
   Observations indicate that the surface freezing line (currently   
   draped from near/north of St. Louis into north-central/northwest MO)   
   generally delineates the transition between rain/mixed precipitation   
   and snow. Heavy snow has recently been observed at Kirksville (KIRK)   
   and Hannibal (KHAE) in northeast MO, with moderate snow observations   
   extending into southeast IA and western IL. Snow rates of near to   
   locally above 1 inch per hour may persist across these areas through   
   the pre-dawn hours.=20   
      
   Farther south into east-central MO, surface temperatures remain   
   near/above freezing with residual low-level dryness, but evaporative   
   cooling of the column should eventually allow for development of   
   moderate to locally heavy wet snow for a period of time this   
   morning. Precipitation intensity may support snow rates of   
   near/above 1 inch/hour and notable visibility reductions, though the   
   marginal surface temperatures could limit actual accumulation rates   
   to some extent. Later this morning (generally after sunrise), parts   
   of east-central MO may transition to mostly rain or mixed   
   precipitation, in response to persistent low-level warm advection.
