First warm advection band of light snow is exiting far northern
Lower and working its way through eastern Upper. Area webcams
show only a light coating on some roads, with little impact other
than a temporary reduction in visibility. Looking upstream, radar
returns are starting to fill in over the central and western UP as
a sheared-out shortwave crosses Lake Superior. However, still not
much filling in up to this point over southern WI down into the
Central Plains as the more potent shortwave slowly gathers steam.
That should change soon as we head into the afternoon and the
system drifts farther east, starting to tap into a feed of Gulf
moisture.
The southward/downward trend in QPF continues across northern
Michigan with the latest suite of 12Z guidance for the impending
winter system. Both hi-res and synoptic guidance hint at this
likelihood for the rest of today through tonight. Have tweaked
PoPs and QPF accordingly, which generally reduced snowfall
amounts through daybreak Wed by an inch or so across most of the
area. At this point that wouldn`t affect the ongoing advisory
across the area, but it does suggest that upgrading to a warning
anywhere is looking less likely. Will continue to monitor trends
this afternoon and evening.
