... Late season wet and heavy snowfall possible over northwest Upper
Michigan...

A broad low pressure system moving east out of the northern and
Central Plains on Thursday will spread precipitation across Upper
Michigan late Wednesday night through Friday morning. While
confidence is high that there will be precipitation... whether this
will be in the form of rain or snow remains difficult to pin down.
At this time... it appears a mix of rain and wet snow will overspread
Upper Michigan west to east on Thursday but then transition to mainly
snow over much of northwest Upper Michigan by early evening. The wet
snow may then fall heavy at times on Thursday night... especially
over the higher terrain... before the precipitation diminishes early
on Friday morning.

At this time... the best bet is the heaviest snow will fall over the
higher terrain of the Keweenaw peninsula... where the current forecast
shows as much as 6 to perhaps 8 inches accumulating through Friday.
Over the rest of the higher terrain northwest of a line from about
Marquette to Crystal Falls... 2 to 5 inches of wet snow appears likely.
The wet... heavy nature of the expected snow will make shoveling and
snow removal very difficult.

Given the large uncertainty on the precipitation type that will
accompany the passage of this low pressure system... stay tuned to
later forecasts and possible advisories or warnings for this evolving
early Spring winter storm.

... Late season snowfall possible over northwest Upper Michigan...

A broad low pressure system moving east out of the northern and
Central Plains on Thursday will spread precipitation across Upper
Michigan late Wednesday night through Friday morning. While
confidence is high on precipitation occurring... the type of
precipitation remains difficult to pin down. At this time... a mix of
rain and snow is expected to spread over the area Thursday before
changing to all snow on Thursday night. There is a possibility the
precipitation will fall as all snow over portions of northwest Upper
Michigan on Thursday.

Slushy light snow accumulations are possible over portions of western
Upper Michigan... but there is the possibility of moderate snow
accumulations over the higher terrain of north central Upper Michigan
and especially the Keweenaw peninsula. With the large uncertainty on
the precipitation type for this system... stay tuned to the later
forecasts for further details on this evolving system.
