What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

321 am edt Fri jun 22 2018

Short term (today-Saturday)
Mid level ridging across the florida peninsula will continue
to weaken today and tonight as a cut off low moves through
the midwest and ohio river valley. The surface reflection of
this low will push a weak boundary trough axis into northern
florida, which will keep moisture elevated across the area,
with precipitable water values of around two inches or more.

The surface subtropical ridge axis will hold across the
florida straits, keeping westerly flow in place over the
forecast area. Under this pattern, a few morning showers and
thunderstorms will be possible developing over the eastern
gulf and along the coast and could shift inland through the
morning. Afternoon thunderstorms will develop over the
peninsula along sea breeze and outflow boundaries, with the
westerly flow pushing the storms inland through the
afternoon and evening, clearing the convection out from
west to east.

A similar pattern will setup Saturday, with light westerly
winds and abundant moisture. Morning showers and storms
developing over the gulf will push inland, then more
scattered storms will develop along sea breeze boundaries in
the afternoon before pushing east and inland. With the west
coast clearing out fairly early in the afternoon, the
highest storm chances will be inland during the mid
afternoon to early evening hours.

Mid long term (Saturday night-Thursday)
A broad u l trough will extend across much of the CONUS to
begin the period with an u l ridge over the florida
peninsula. An u l disturbance over the eastern great lakes
will weaken on Saturday as it lifts northeast and is
absorbed by a digging northern stream trough over eastern
canada. An u l disturbance will drop in over the central
plains Sunday and Monday which will help build the
downstream ridge over the southeast u.S. And florida.

U l pattern change across the CONUS early next week as a
strong u l trough pushes onshore the west coast of the
u.S. With strong quasi zonal flow develops across the
northern tier eventually extending from the pacific
northwest to new england by the end of the period... And a
strong u l ridge over the southern tier of the u.S. With the
center of the u l high gradually retrograding from the
southeastern states to the southern plains by mid week.

Warmest temperatures across west central and southwest
florida will likely occur Monday and Tuesday when the center
of the u l ridge is closest to the region with greatest 50h
around 592 or 593.

At the surface, transition day as strong high pressure over
the central atlantic gradually retreats a bit to the east.

The ridge axis will extend across the central florida
peninsula on Sunday. This will allow east southeast boundary
layer flow to develop over southwest florida which will
increase convergence along the west coast sea breeze
boundary... With higher pops and an increase in areal
coverage of afternoon showers thunderstorms south of the
ridge axis. Onshore flow north of the ridge axis across the
nature coast should still promote best chance of
showers thunderstorms during the late morning early
afternoon with activity gradually pushing inland through the
day.

High pressure will remain over the florida peninsula,
however the gradient will weaken early next week. This
will likely allow scattered showers thunderstorms to develop
along the west coast sea breeze boundary over the coastal
counties during the early afternoon... With the boundary
gradually pushing inland through the day eventually
colliding with the east coast sea breeze boundary over the
interior which will enhance shower thunderstorm activity
during the late afternoon to early evening hours. Stronger
insolation on Monday and Tuesday could lead to a few strong
storms with damaging wind gusts. Due to the weak boundary
layer flow, could see outflow boundaries push back to the
coast with a continued chance of showers thunderstorms
through the evening hours each day across all of west
central and southwest florida... Especially Monday and
Tuesday evening. Proximity to the u l ridge center will
create strong subsidence over the forecast area likely
delaying onset of convection. These type of set ups can
create favorable conditions for late evening thunderstorm
activity around tampa bay with excessive lightning... But
this is speculative several days out.

Aviation
GenerallyVFR conditions will continue overnight. A few
showers and thunderstorms will be possible moving onshore
near the tampa bay area terminals around sunrise, and could
cause brief flight category disruptions. Scattered
thunderstorms will develop across the area during the early
afternoon. These storms will clear out from west to east
through the afternoon and early evening, withVFR conditions
returning overnight.

Marine
The ridge of high pressure will remain south of the area
through Saturday, keeping light westerly winds in place
across the eastern gulf of mexico. Isolated to scattered
showers will be possible each day, mostly during the early
morning hours. Winds and seas will remain below headline
criteria, except in the vicinity of some of the stronger
thunderstorms.

Sunday through Tuesday, the ridge of high pressure will
lift north to a position across the florida peninsula and
the eastern gulf of mexico, with light winds becoming more
variable. Daily thunderstorms over the florida peninsula
could shift west into the gulf through the afternoon and
early evening, bringing locally gusty winds and rough seas.

Fire weather
Relative humidity will remain well above critical levels
through the forecast period.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

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.
