    Areas affected...Northern Wisconsin...Upper Peninsula...and northern
    Michigan

    Concerning...Heavy snow

    Valid 060024Z - 060630Z

    SUMMARY...Heavy snow with 1-2" per hour rates are expected to
    develop across northern Wisconsin, the Upper Peninsula, and northern
    Michigan this evening.

    DISCUSSION...A swath of moderate to heavy snow is falling across
    eastern Minnesota, central/northern Wisconsin, and into Upper
    Peninsula of Michigan. Frontogenesis and isentropic up-glide are
    occurring over this region with the strongest lift located between
    650 mb and 500 mb ( -5 C and -15 C). Stronger lift is located
    slightly farther south across southern Wisconsin/far northern
    Illinois where profiles are more favorable for sleet/freezing rain
    (see MCD 070). However, enough upward motion within the dendritic
    growth zone should allow 1"+ per hour snowfall rates to develop
    across portions of northern Wisconsin, the Upper Peninsula of
    Michigan, and northern Michigan this evening. Some local snowfall
    rate enhancements of 2" per hour may occur as the shortwave trough
    moves over the region this evening. Snow will taper off from west to
    east after 05z as the best defined for lifting/upward motion shift
    eastward across the Great Lakes region.
