    Areas affected...Northeast Ohio...northwest Pennsylvania...western
    New York

    Concerning...Snow Squall=20

    Valid 292014Z - 300015Z

    SUMMARY...Snow squall conditions are possible as a secondary cold
    front moves off of Lake Erie. Moderate to briefly heavy snowfall and
    strong wind gusts will lead to reduced visibility with this
    activity.

    DISCUSSION...A secondary cold front is moving through the Great
    Lakes region as a potent upper low continues through southern
    Ontario/Quebec. A coherent band structure has develop as the front
    has approached Lake Erie. This band is expected to move onshore and
    progress into Ohio/Pennsylvania/New York. Moderate to briefly heavy
    snowfall may occur with this activity. Strong cold advection has led
    to steep enough lapse rates in the boundary layer which could could
    contribute to enhanced wind gust potential above what has already
    been ongoing synoptically this afternoon.

    Areas affected...northeast Kansas

    Concerning...Severe potential...Watch possible

    Valid 122044Z - 122215Z

    Probability of Watch Issuance...40 percent

    SUMMARY...A corridor of at least marginally severe hail or wind may
    develop across most of northeast Kansas, perhaps western Missouri
    this evening.

    DISCUSSION...Despite northeasterly boundary-layer winds and cool
    temperatures, sporadic elevated storms have affected the region for
    much of the day. Recently, a stronger/larger area of storms has
    developed, and produced a wind gust of 51 kt at Concordia, KS.
    Models suggest up to 2000 J/kg elevated MUCAPE is present currently.

    Aiding storm intensity are steep lapse rates aloft and favorable
    effective shear over 40 kt. Given the size of the existing storm
    cluster, this zone bears watching, with possible watch consideration
    downstream over the next hour or so.
