  • Balmy breezes will continue overnight across the Tampa Bay area as a tight pressure gradient has set up between Hurricane Isaac to our west and high pressure over the Atlantic.

    On Wednesday we begin to transition to a more typical summer pattern as high pressure builds westward from the Atlantic. The ridge axis will stay to our north, which will maintain an easterly flow over the region.  With this set-up, we expect late afternoon thunderstorms, with only limited activity during the first part of the day. The best chances of rain will be across the nature coast, with slightly lower amounts to the south.
