.DISCUSSION...

Drier air will remain in place for another day but we will start
to slowly see moisture increase. However, we likely won`t see any
real moisture return until late in the week. That will lead to
minimum humidity values dropping into the 30 to mid 40 percent
range today, and in the 40s Tuesday and Wednesday. Lackluster
winds will be in place through the period and this will limit any
critical fire weather conditions.
