   CONCERNING...WINTER MIXED PRECIPITATION 

   VALID 230301Z - 230700Z

   SUMMARY...MIXED PRECIPITATION TYPES WILL CHANGE TO ALL SNOW WITHIN A
   NARROW ZONE IN WHICH SNOW RATES MAY APPROACH ONE INCH/HR FOR A
   COUPLE OF HOURS. PRECIPITATION WILL DIMINISH IN INTENSITY OR END
   FROM WEST TO EAST IN THE 05Z-08Z TIME FRAME.

   DISCUSSION...A NARROW ZONE OF MIXED PRECIPITATION TYPES EXTENDS
   ACROSS PORTIONS OF CENTRAL IL AND CENTRAL/NRN IND AT 0230Z WITHIN A
   BROADLY CYCLONIC MID AND UPPER LEVEL FLOW REGIME. FRONTOGENETIC
   FORCING WITHIN THE SATURATED 850 MB-700 MB LAYER WILL CONTINUE TO

   CONTINUED TRANSITION FROM RAIN TO SNOW WITH SNOW RATES OF ONE
   INCH/HR...LOCALLY HIGHER...POSSIBLE FOR A COUPLE OF HOURS AT ANY
   GIVEN LOCATION. FORECAST SOUNDINGS ALSO SUGGEST DRIER AIR WILL
   OVERSPREAD THE AREA IN THE 05Z-08Z TIME FRAME RESULTING IN
   PRECIPITATION ENDING OR DIMINISHING IN INTENSITY FROM WEST TO EAST.
