.DISCUSSION...
Shower and thunderstorm activity is set to become more widespread
over the next several hours as the low level jet intensifies and
isentropic lift becomes more pronounced across the region. Elevated
instability and deep layer wind shear will be sufficient for some
of the storms to become strong to severe with large hail the main
concern. Heavy rain and the potential for flooding will also be of
concern as training of storms will be possible.

Have made some adjustments to the grids for Tonight to better reflect
current trends in observations and the latest short term model guidance.
