Tonight: We'll deal with mostly clear skies overnight and lows dropping to the 30s and 40s.
Friday: The overnight cold front will have little impact on our morning lows, but you'll feel it during the afternoon as highs only reach the 60s and 70s... you know, normal temperatures for this time of year. ;)
Extended: Behind another push of even cooler air, temperatures dip to the 50s and 60s by Sunday. On Saturday, there's a tiny chance for some stray rain showers in the lower elevations and light snow in the higher elevations. It will be blustery as well.
