Toasty conditions will continue across the Florida Keys, but minimum RH values anywhere from 60% to almost 70% will reflect the pockets of relatively drier air across the area. Isolated to modestly scattered showers and thunderstorms will be possible throughout the day, but the aforementioned dry air will limit development. Over the course of the middle of the week, moisture will gradually increase in the lower levels, and will help to increase humidity and rain chances.
