Pleasant Labor Day weekend ahead

After the passage of the cold front on Thursday, temperatures return to seasonal or slightly below seasonal in the 70s, and some lower 80s for Saturday. Not quite the sweltering end to summer that most of us look forward too, but after a busy severe weather week; the quiet is welcomed.
