The daily forecast anywhere in Florida from late May through September will show afternoon thunderstorms pretty much every day,that's just the way it is,it gets hot into the 90's and sometimes upper 90's and the heat just brings in the storms.I'm down in Miami and we had one of the driest Junes ever,and June is usually the rainiest month,it rained but about 1/3 of the normal rain we get in June.Orlando also had a dry June the early part of the month but from reports I've read there were plenty of storms the latter part of the month.The typical day will start sunny and hot and around 1-3pm you'll see the dark clouds form,after that the storms will come they could be brief or last a couple of hours,the majority of them will be gone by 6pm or so but you can expect rain anytime.
