.DISCUSSION...

Much drier air has filtered into the region, which
will remain in place into middle parts of the upcoming week. Main
focus will be on strong afternoon mixing each day, resulting in
lower dewpoints down into the 50`s today through Tuesday. MinRH`s
range in the low to mid 30`s and can`t rule out some it reaching
in the upper 20`s. Winds will remain light with no rain chances
through at least Thursday. There will also see a slow/steady
increase in moisture mid/late week as winds switch more easterly
to eventual southeasterly pulling Gulf moisture north.
