A frontal boundary will be nearly stalled over northeast FL on Saturday, and combined with some energy aloft will result in numerous to widespread showers and storms over Jacksonville. Periods of heavy rainfall appear likely in addition to high thunderstorm/lightning chances, with the timing of highest coverage likely to be during the afternoon and evening hours. Exactly where the front sets up will help to determine more narrowed down rainfall amounts as well as coverage of showers/t`storms, though confidence is high in elevated rain chances throughout the weekend at this time. Stay tuned to the latest forecast over the coming days - we are standing by if you would like further updates late this week. .SATURDAY...
