    Surface ridge with distinct anticyclonic vorticity advection episode
    over Southeast Michigan this evening continues to lead to low sky
    fraction. High static stability remains in place between 9.0 and 18.0
    kft agl. A somewhat noisy solution space exists with regards to
    convective development overnight near the Ohio border. Old convective
    shortwave energy is expected to push into the state which will help
    in eroding the stability aloft. Low confidence exists in any shower
    or thunderstorm development impacting Lenawee or Monroe counties
    tonight due to very aggressive anticyclonic flow trajectories. Strong
    signal then exists for strong subsidence with amplifying
    anticyclonic wave break folding down into Southeast Michigan
    Thursday. VFR weather anticipated throughout the day Thursday. Ridge
    riding MCS system to remain across portions of northern WI and U.P.
    through Thursday evening.
    For DTW...VFR weather tonight and Thursday. Very low confidence
    exists in thunderstorm development south of DTW or south of Ohio
    state line overnight.
