After a quiet morning, clouds will be on the increase today with a chance for scattered showers this afternoon. Showers look likely tonight as a cold front moves in from the west. Showers exit early tomorrow and skies will become partly cloudy. Look for much cooler temperatures over the weekend with highs in the 50s tomorrow and 40s Sunday. By Monday morning, patchy frost looks likely with lows falling into the low-mid 30s. Much of next week looks a little bit cool by seasonal standards.
