.DISCUSSION...

Drier air that filtered into the region over the weekend will
remain in place through the middle of this week. Main focus
will be on strong afternoon mixing each day, resulting in lower
dewpoints down into the 50s. MinRH range in the 30s, can`t
completely rule out brief dips into the upper 20s. Winds will
remain light with no rain chances through at least Friday.
Will also see a slow/steady increase in moisture mid/late week
as winds switch more easterly to eventual southeasterly pulling
Gulf moisture north.
