    This is kind of far out for a severe weather thread, but there isn't much going on and it looks like a synoptically evident severe setup on paper.  We look to have a respectable surface low (by July standards) that will move through the region, accompanied by sufficient moisture and a plume of at least modestly steep mid level lapse rates.  Should have some nice flow aloft/shear to work with as well.  Putting it all together, I think the potential is there for a significant severe wx event, but obviously we'll have a better idea as the time approaches. 

    Been eyeing this since yesterday. Looks interesting 

  2. Model guidance suggests that the low-level jet will
       strengthen considerably during the evening, with forecast soundings
       showing very favorable hodographs for supercells capable of very
       large hail, damaging winds, and a few tornadoes.  Considered adding
       at 10% tornado threat area, but will defer to 20z update when
       eventual position of the boundary is better defined.
    
       Storms are expected to congeal into a bowing complex through the
       evening, affecting portions of north-central MO with the threat of
       rather widespread damaging winds and hail.

    Usually, unless there is a strong system with a LLJ, the outflows sag south and the heavy rains fall south of the models...like the HRRR is showing

    It is very rare you have the models dumping this much rain around here...I have seen see  it in southern IL/KY into the mid south in winter/early spring flooding events near the OH river into TN...and of course tropical systems

    July 1996 deluge fell during a drought if a recall correctly

    NE IL is in drought but areas SW near me are not

    I agree. Heavy rain events in our region are almost always modeled too far north

    Long Term...(Thursday night through Tuesday)
    Issued at 330 AM EDT Wed Jun 23 2021
    
    Potential for serious to life threatening heavy rain and
    flash flooding this weekend into next week as deep moisture advects
    northward ahead of a warm front over the lower Mississippi Valley
    and central Plains and a cold front over the northern Plains. The
    warm front is expected to lift northeast across central Indiana
    Friday as the cold front approaches from the northwest. Meanwhile, a
    Canadian trough will dig southeast out of central Canada and result
    in southwest flow aloft over the Ohio Valley. The cold front will
    become aligned parallel to the upper flow as the front moves to just
    northwest of central Indiana this weekend. This will likely result
    in the front stalling out nearby with waves of low pressure moving
    along it. The persistent synoptic forcing will tap into the deep
    moisture, seen in precipitable water amounts greater than 2 inches,
    and instability and result in widespread thunderstorms starting
    Friday night. The alignment of the front with the upper flow will
    bring the threat for training and the potential for several inches
    of rain to fall over a widespread area this weekend into next week.
    
    The highest PoPs will start off over the northern Wabash Valley and
    gradually spread southeast over the weekend into next week.
    
    WPC is advertising over half a foot of storm total QPF over the
    Wabash Valley by next Tuesday with lesser but still impressive
    amounts over southeastern sections.
    
    With persistent warm advection, temperatures still look like they
    could make it to the lower 80s each day despite the extensive
    convection.
