  1. Attention then turns towards this afternoon and evening as
    additional convection is expected to redevelop within the warm and
    humid atmosphere. Temperatures are expected to climb into the 80`s
    across the area, and dew points will peak in the upper 60`s. This
    means there will be plenty of moisture for storms to feed off of in
    the afternoon if convection can get started. Today is a bit
    different than yesterday`s convection as there isn`t really a
    significant source of synoptic level forcing to initiate storm
    development, so determining location and timing of storms is a bit
    more difficult. Water vapor imagery shows a bit of a moisture
    boundary from southern Illinois down to northeast TN/southwest VA.
    This could axis could be one of the forcing mechanisms for storm
    initiation, especially south of this boundary...In addition to any
    outflow boundaries left over from the overnight convection moving
    out of eastern Kentucky. At this point the expect storms to
    redevelop in the afternoon hours with the strongest solar heating
    taking place. Forecast soundings and mesoanalysis continue to show
    ample surface based CAPE of up to 4,000 J/kg in the most aggressive
    models, and steep mid level lapse rates of over 7-8.5 C/km. Luckily
    the deep layer shear looks fairly weak, and is mostly uni-
    directional across our area, which will hopefully limit (but not
    totally eliminate) tornadic development. An additional surge of
    storms could move into the area after sunset from stronger storm
    development over western Kentucky, but still some uncertainty if
    this will move more into WV or VA.
    
    The main threats with storms this afternoon and evening will be
    Large hail possibly up the size of ping pong balls, and strong
    straight line winds in excess of 70 mph. In addition storms training
    over the same location could cause isolated flooding of low lying
    and poor drainage areas, and an isolated tornado cannot be ruled out
    at this point.
    
    Storms will eventually come to an end after sunset and loss of solar
    energy. Fog will be possible overnight as skies slowly clear out,
    mainly in areas that receive rainfall from the afternoon storms.
