Tracking lower rain chances, cool down by the weekend

TONIGHT: Partly cloudy with lows in the mid-upper 60s. Spotty showers possible early. Fog developing late into Wednesday morning.

TOMORROW: Partly to mostly cloudy with a slight chance for showers and possibly a thunderstorm south of I-70. Highs in the mid-80s.

EXTENDED: The cold front responsible for this week's rain will slowly move south over the course of this week, pushing rain chances farther south each day. Once the front finally gets south of us on Thursday night, high pressure settles in, bringing in cooler and much less humid air in time for Labor Day weekend. Temperatures Friday will top out in the upper 70s to around 80, with much lower humidity as dew points fall into the 50s. It's gorgeous through Sunday with temperatures in the low to mid-80s over the weekend. Another front moves in Sunday night through Monday and brings a chance for rain Labor Day through Tuesday, but temperatures cool significantly behind this system as high temperatures remain in the 60s and 70s and lows fall into the 40s and 50s.
