JACKSONVILLE, Fla -- Skies will clear tonight and combine with light winds and dry air to make for a cold night with lows in the 30s inland and 40s near the coast. A bit of patchy, light frost will be possible well inland between Highway 301 and I-75. A warming trend will begin Thursday under partly sunny skies with afternoon highs close to 70 degrees. Temperatures will turn much warmer Friday and Saturday with highs in the upper 70s to mid 80s. The wildfire danger will become very high the next few days before showers increase late Saturday into Saturday night.
