We've had some outstanding weather, but colder spots last night dipped toward the 30s, and this weekend is expected to be wet and rainy, with a chance for thunderstorms. Be prepared for wet weather by bringing along some extra dry clothing, and alternative plans to avoid mud or troublesome water crossings. Mountain streams can rise quickly with locally heavy rains. Watch the weather to avoid the worst of it; and be sure to take shelter during lightning storms. Never be above treeline or on water when you can hear thunder.
