Discussion
Currently a cold front is stalled out in the
florida straits with high pressure in the southeast which
has caused an overrunning scenario for Tuesday.

A trough is pushing along the front which has enhance shower
activity. There will be a sharp contrast when it comes to rain
shower chances. Areas north of hillsborough county will
stay mostly dry with chances lower than 40 percent. South of
i-4 shower chances will increase quickly with our southern
counties around 90 percent. The cooler northeast flow and
overcast skies will also keep temperatures cool with high
staying in the 60's.

The front will finally start to move away by Wednesday which will
slowly push out the cloud cover and shower activity and allowing our
temperatures to get back into the 70's. Thursday and Friday will be
the opposite of the first half of the week. Pws could be as low as
0.3 by Friday which means we will have plenty of sunshine to end the
week with highs staying the mid 70's.

Temperatures will be on the rise by the weekend with most of us back
in the 80's. Models have come into better agreement on the next
frontal system heading our way. It looks like the front will be
moving a little slower which means the weekend will stay
dry. A few showers will be possible on Monday but better
shower chances will be coming back into the forecast by next
Tuesday.

Aviation
PrevailingVFR with tempo MVFR conditions through the next
12 to 15 hours with vcsh and shra. Rain starts to diminish
after 00z with prevailing MVFR with tempo ifr cigs. Winds
will remain out of the NE with gusty conditions.

Marine
We continue to be sandwiched between a cold front and a high
pressure keeping winds up for the next couple of days. Most
of the waters will be caution to advisory level through at
least Wednesday morning. The cold front starts to move away
on Wednesday and winds will start to drop and the end of
the week looks to be quiet.

Fire weather
Overrunning cold front will keep low level moisture high
and rain showers in the forecast for the beginning of the
work week with no fire weather concerns.

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.
