Overnight
As the cold front moves east overnight, the threat for flash

Meanwhile, further north in north-central Wisconsin, freezing rain
will gradually end between 6 AM and 8 AM. Up to a quarter inch of
additional ice will be possible in eastern Taylor County and up to 2
tenths of an inch in Clark County. As a result, no changes are
likely needed for the Winter Weather Advisory in these counties.
This Afternoon and Evening
The surface low will move northeast across Ontario this afternoon
and into Quebec this evening. Wrap-around precipitation, associated
with the deformation band, will move east across north-central
Wisconsin. Elsewhere, the combination of steep 950-850 mb lapse rate
and surface-based CAPES up to 50 J/kg will result in scattered
rain/snow showers. There might be some graupel at times with some of
the stronger showers. High temperatures will range from the upper
30s to around 50.
Easter Sunday Afternoon and Sunday Evening
A shortwave trough will move southeast through the region during the
afternoon of Easter Sunday and Sunday evening. Steep 950-900 mb
