    Areas affected...MN North Shore to far northern Lower MI

    Concerning...Heavy snow=20

    Valid 181016Z - 181445Z

    SUMMARY...Moderate to heavy snow bands will increase in coverage
    through late morning along portions of the Minnesota North Shore to
    far northern Lower Michigan. Rates of 1 to 2 inches per hour should
    be common, with localized blizzard conditions along east-facing lake
    shores.

    DISCUSSION...Leading swath of moderate to heavy snow has been most
    persistent across the MN North Shore to the Keweenaw Peninsula of
    western Upper MI. An upstream lobe of strongly forced ascent from
    east-central MN to southeast WI will shift northeast through late
    morning. While the activity attendant to this ascent is largely
    rain, including a flurry of recent thunderstorms in southern WI, it
    will transition to winter precipitation types as it spreads across
    the Upper Great Lakes. Snowfall rates will likely be enhanced with
    transient bursts of 2 to 3 in/hr possible along the interface of
    sleet/freezing rain to all snow transition. Where this transition
    point occurs is more uncertain with southeast extent in MI, where
    subtle differences in the low-level thermal profile should have
    profound impact on the degree of mixed-phase precip versus nearly
    all snow.=20

    Localized blizzard conditions along east-facing lake shores should
    persist into late morning, before eventually waning as the surface
    pressure gradient relaxes towards midday.
