Temperatures over the weekend will end up a bit cooler than recent days, but still about 20 degrees above average with highs in the mid and upper 70s.  Isolated showers and thunderstorms are possible this weekend, but the best chance for rain will hold off until Sunday night when a cold front passes through.  Cooler conditions will follow early next week with highs by Tuesday only near 50 with a few mixed rain and snow showers possible.
