Discussion (tonight - Monday)
Showers and thunderstorms beginning to develop now as temperatures
climb into the lower 90s. Earlier activity near sarasota bradenton
has sent an outflow boundary northeastward through manatee and
part of hillsborough county. This should become a focus for
additional activity soon. Motion will be slowly northwestward,
except where outflow boundaries intervene.

The overall pattern will change significantly over the next few
days. A deepening eastern u.S. Upper-level trough will help to
push a weak frontal boundary all the way to the northern gulf
coast by late Tuesday and Tuesday night. The low-level ridge that
has resided north of the region will be displaced to our south and
east tonight and Tuesday. This will result in west southwesterly
flow for Tuesday, pushing higher rain chances well inland during
the afternoon. As the frontal boundary settles into the deep south
on Wednesday, enhanced westerly flow will develop with deep
tropical moisture in place between the boundary and the departing
ridge. We will likely see a large area of showers and storms over
the gulf Tuesday night moving onshore during the morning hours on
Wednesday. The best chances for rain will be from the tampa bay
area north. This pattern persists into Thursday, then the upper-
level trough begins to weaken and lift northeast. By Friday, a
large area of high pressure over the mid-atlantic states will
bridge the decaying frontal boundary and bring a return to
easterly flow. The Saturday to Monday time-frame looks like more
typical summer-time weather with most storms occurring during the
afternoon and evening hours.

Aviation
Early storms near srq have dissipated sending an outflow boundary
toward the northeast. This may help focus storm activity east of
the tpa, pie, and srq terminals through the day. Expect late
afternoon activity around lal, fmy, and rsw.

Marine
High pressure will be displaced to our south and east tonight and
Tuesday resulting in a prolonged period of west to southwest
winds. A weak cold front will reach the northern gulf Tuesday
night or Wednesday, bringing enhanced westerly winds and numerous
showers and storms offshore the nature coast. Winds and rain will
gradually subside Thursday with a return to easterly flow by the
weeks end.

Fire weather
No fire weather concerns. Locally heavy rainfall is possible
Wednesday and Thursday, especially near and north of the tampa
bay area.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
