   NWS Storm Prediction Center Norman OK
   1240 PM CST Sun Dec 05 2021

   Areas affected...Northern Lower Michigan

   Concerning...Heavy snow 

   Valid 051840Z - 052215Z

   SUMMARY...Moderate to occasionally heavy snow expected to persist
   through the afternoon and into the early evening across northern
   Lower Michigan.

   DISCUSSION...Regional radar composite shows increasing precipitation
   rates across central Michigan in response to frontogenesis and
   strengthening isentropic ascent. Moderate to occasionally heavy
   snowfall is expected to develop across all of northern Lower
   Michigan in the next 1 to 2 hours and persist into the early
   evening. Continued low-level warm air advection will eventually
   change rain to snow from south to north across the region. However,
   the majority of the precipitation is expected to fall as snow with
   rates up to 2 inches per hour.
