.DISCUSSION...
Main update item at this time is to lower pops across far NE OK
and NW AR and remove thunder for the morning hours. Area to
remain capped for most if not all of the afternoon hours which
will limit surface based activity...but will leave low pops as
they are between 18z and 00z. Areal coverage of rain/thunder expected
to blossom during the evening as low level winds organize as the
upper system approaches. Heavy rain and severe threats will
increase as well...with heavy rain/flash flooding still expected
to become the primary threat by Saturday as widespread rainfall
will continue throughout the day...and into Saturday night/Sunday
morning. Rain chances will be on the decrease Sunday as the
system begins to lift off to the northeast.

Updated ZFP/PFM/AFM/freshened FFA already sent.
