Mesoscale Discussion 0278
   NWS Storm Prediction Center Norman OK
   1046 PM CDT Thu Mar 21 2024

   Areas affected...portions of east-central Minnesota into central
   Wisconsin

   Concerning...Heavy snow 

   Valid 220346Z - 220645Z

   SUMMARY...A few instances of 1+ inch/hr snowfall rates are possible
   over the next few hours.

   DISCUSSION...A 500 mb jet streak is overspreading the Upper MS
   Valley, supporting strong low-level warm-air advection within a
   sub-freezing troposphere. As a result, 700 mb frontogenesis is
   increasing along the MN/WI border, boosting deep-layer ascent within
   a deepening dendritic growth zone. Multiple surface observations
   have recently shown heavy snow ongoing across Sherburne to Chisago
   Counties in Minnesota. Additional instances of heavy snow are likely
   along the 700 mb frontogenesis axis over the next few hours, with 1+
   inch/hr snowfall rates and instances of reduced visibility possible.
