Chance of Heavy Rainshowers/Storms on Thursday (?)

Thinning High clouds should make for a partly to mostly sunny day with a chance
of thunderstorms or showers as noted in locations above later to early evening 

MONDAY/TUESDAY: GFS continues to show and easterly 'tropical wave' ; per discussions from the NWS Offices there is some question concerning how it will be handled in coming days; the GFS shows it dampening out yet making it to Florida as increased atmospheric moisture before the next front arrives. It was questioned whether the front would beat out the moisture in the previous post, but it was thought the moisture 'wave' would win the race. Since that post the GFS a few times showed the moisture might not even make it here at all, but that has flipped back around to the original thinking. What this means is that no effect Monday and Tuesday, with conditions somewhat similar to what we've had the past few days as it is, other than a better chance of some thunder North Parts of the state today.

(Global Forecast System) for Monday sunrise.
Note the lower right corner  showing the leading edge of deeper moisture.
WEDNESDAY: Chance of a shower or two from the Cape and South sunrise on through the remainder of the day, and maybe some thunder interior to west side of state. 

Here's where changes will be watched for. The latest GFS damps the wave out to cross South Florida on Wednesday  then to get caught up in the next front (see above image)...  converges into the front for Thursday afternoon as it approaches. Could be a chance of some heavy type thunderstorm activity on this day as a result of that occurs, but much will change before that time in regard to the models.  In any case, Thursday appears to be the day with the best rain chance in quite some time to come, from then and beyond as well.

BEYOND THURSDAY: Chances of showers/thunder South Central/South Florida as front goes through with big drying trend to follow...notable by Saturday morning and through the weekend.
