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. .REST OF TODAY... Sky/weather.........Mostly sunny (20-30 percent). Chance of pcpn......10 percent.
