6z GFS shifted a tad south and widened the band a bit with general 6-12
MKE AFD this morning:
Confidence is high (70-90%) in widespread accumulating snowfall
for southern Wisconsin late Thursday through at least Friday
morning, as a shortwave moves through the region. The big
question with this system is the track of the stronger
frontogenetic forcing. Models still vary a bit with the
placement of the strong frontogenesis, ranging from along/just
north of the northern forecast area border to along the WI/IL
state line. Locally higher amounts are expected with the
stronger forcing, but it`s too early to pin down totals,
especially where these higher amounts may wind up. Given that
this system has slowed down a bit, confidence is increasing that
accumulating snowfall will impact the Friday morning commute,
especially where any banded snowfall sets up due to the stronger
forcing.
