area forecast discussion
national weather service tampa bay ruskin fl
827 pm edt Wed may 24 2017

Update
Regional radar composite is showing a broken band of
thunderstorms just north of the forecast area, which is
forecast to push south through the area overnight ahead of
the cold front. The hrrr is forecasting that this line will
intensify somewhat after midnight as it moves into the
tampa bay area, although a much more compact line of storms
is forecast than what was seen earlier.

Apart from the next round of thunderstorms, the biggest
area of concern remains the wind, although winds are
gradually subsiding. The lake wind advisory is still up
through 10 pm, and coastal flood statements and rip current
advisories are still in effect until Thursday morning.

Some additional tweaks were made to the rain chances and
weather grids from what was updated earlier this evening. No
other changes are planned for the evening update.

Aviation
Most of the storm activity has moved away from the taf
sites, but another band of showers or storms is forecast to
pass north to south through the overnight hours with the
front, with brief ifr conditions possible. Widespread MVFR
ceilings will continue to impact the area TAF sites through
the overnight hours, although occasionalVFR periods will
be possible. Otherwise, winds will turn to more westerly by
Thursday morning.

Marine
Winds will start to subside through the next few hours, but
seas are expected to remain at or above advisory levels
through the overnight hours as the cold front passes through
the area. West to northwest winds of 15-20 knots are still
expected Thursday morning, so cautionary headlines will
still be needed after the advisory is dropped, with
conditions continuing to improve through the rest of the
day.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
