  1. Tidbits from Long Term AFD by CLE and IWX...

    CLE: 

    .LONG TERM /WEDNESDAY THROUGH SATURDAY/...
    A large upper level ridge over the eastern United states will begin 
    to amplify slightly by the end of the week as a deep digging upper 
    level trough dives into the Central Plains states. Surface high 
    pressure over the Ohio Valley will settle south and build as it 
    moves out to the Atlantic Ocean from the Georgia coast. Warm air 
    advection will take place on the west side of the high pressure into 
    the forecast area for much of the latter half of the week.  As the 
    upper level trough begins to dive into the Plains States toward the 
    end of the week, a series of surface low pressure systems will 
    develop over the Oklahoma Panhandle. The first will move northeast 
    through the central Great Lakes Friday night keeping our area in the 
    warm sector.  However, looking further out, the second Panhandle 
    Hook appears it will track deeper south and keep the local area on 
    the cold side of the low.  Another possible winter storm will need 
    to be watched for Sunday as the week progresses. All of the long 
    range models agree on colder air and development of this low at this 
    time.

    IWX:


    Guidance still advertises an active pattern setting up for the 
    weekend with a storm brewing over the central states. The features 
    to watch are a cut-off low off the coast of the Baja and a trough 
    arriving onshore of British Columbia late in the week. These 
    features will dictate how the storm from the Central U.S. evolves. 
    Stay tuned!
