Areas affected...portions of central and northeast Indiana into
southeastern Lower Michigan

Concerning...Heavy snow=20

Valid 251514Z - 252045Z

SUMMARY...Moderate to heavy snow should continue northeast across
central and northern IN, extreme northwest OH, and far southeast
Lower Michigan into the mid-afternoon hours. A few instances of 1+
inch/hr snowfall rates are possible in the heavier bands.

DISCUSSION...A surface low is centered around the IN/KY border and
is poised to continue drifting northeast toward Lake Ontario through
the day while also intensifying. Strong surface-700 mb
warm-air/moisture advection will continue to feed relatively rich
moisture to the dendritic growth zone (-12 to -17C layer). Upglide
of this moisture while wrapping around the surface low should
continue to foster at least moderate to occasional bouts of heavy
snow through 20Z northwest of the mid-level dry slot. The heaviest
snow (including brief instances of 1+ inch/hr snowfall rates) will
be most likely where 700 mb frontogenesis and associated lift will
be strongest. Latest mesoanalysis suggests that this corridor is
situated across central into northern IN/extreme northwest OH and
far southeast lower MI.
