.DISCUSSION...

Mostly sunny skies expected this afternoon with highs reaching
the low 90s and light winds out of the west. Can`t completely
rule out a stray shower this afternoon, but chances are around
10 percent or less, and not expecting anything more than a brief
shower if one does occur.

Overnight, skies clear and light winds continue with lows
reaching the upper 60s to low 70s.

Sunny skies are expected on Independence Day with highs in the
mid to upper 80s. Humidity will be notably lower as well, which
makes it feel much more comfortable.
