LONG TERM /Friday through Wednesday/...

GFS and ECMWF still in good agreement on evolution of late week
system. Rain will be increasing from the northwest corner Friday
and spreading eastward through Saturday. The surface low should
move from the lower MS Valley through the TN Valley on Saturday.
CAPE values not impressive for our area...less than 200 J/KG with
the surface front on Saturday. So for now...will continue to 
leave out mention of thunder. Rain ending on Sunday with passage 
of the upper trough then dry for Monday. Models diverge again for 
the onset of the Tuesday and Wednesday event. However...have left 
low pops for Tuesday with an increase in pops on Wednesday.
