From Chief Meteorologist Mike Modrick:
High Saturday: 90
Winds S 5-15 mph

One more warm day, then back to more typical temperatures for this time of year. A cold front moves through Saturday night, and an isolated thunderstorm is possible with the front. Then cooler air returns with strong winds on Sunday.

Labor Day will be an average day with highs in the 70s.
