    Areas affected...northern Wisconsin through western Upper Michigan

    Concerning...Freezing rain

    Valid 040751Z - 041245Z

    SUMMARY...Freezing rain is expected to gradually increase in
    coverage and intensity through the early morning, initially across
    northern WI, but expanding into western portions of lower MI after
    11Z. Rates occasionally from .05 to locally exceeding .1 inch per
    hour are possible.

    DISCUSSION...Early this morning a quasi-stationary front extends
    from a very weak surface low in southeast MN eastward through
    central WI. North of this boundary surface temperatures are below
    freezing, ranging from around 32F to 27F. WV imagery shows a
    progressive shortwave trough over the Northern Plains, and this
    feature will contribute to slight deepening of the surface low and
    modest strengthening of a southerly low level jet across WI as it
    continues eastward. As a result, warm advection and isentropic
    ascent will gradually increase within baroclinic zone across
    northern WI. These processes will contribute to development of a
    melting layer and a shallow, weak unstable layer above the surface.
    Scattered showers over central WI will spread northward, and
    precipitation should gradually become more widespread over northern
    WI within the zone of increasing isentropic ascent. Temperatures in
    the melting layer will warm such that the dominant precipitation
    type should become freezing rain with rates at times up to .1 inch
    per hour in heavier convective elements.
