More Uncertainty in the forecast
The forecast for the coming several days is dependent upon the movement of a closed low, now over the central portion of the country.
As is often the case, the models do very poorly predicting weather associated with a closed low, and the situation this week is no different. Already, the rain predicted by the models for tonight into Wednesday is now uncertain because the NAM and GFS are handling the closed low somewhat differently. The GFS is much wetter over the next several days, while the NAM has high pressure building in by Thursday. I would bet on the GFS this time.
The weekend forecast is even more uncertain and dependent upon which model gets the short term forecast right. Saturday, though, currently looks wet. (The tropical storm, for next week, predicted by the NOGAPS now has disappeared.)

Change in Today's forecast- Tues
The original forecast for today, Tues, was that there would be a cold front passage late in the afternoon, with rain and thunderstorms possible. The GFS now has the front slowing down and stalling over us tonight into Wednesday, giving us rain late tonight into Wednesday.
The NOGAPS continues to forecast a tropical storm or hurricane early next week for the western side of Florida.
