6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

High pressure builds west from the western atlantic into the southeast u.s. Sunday into early next week, with local winds becoming more east to southeasterly as a result. Little change in seas expected. Winds and seas higher in and around showers and storms through the period.

area forecast discussion
national weather service tallahassee fl
1244 pm edt Sat aug 19 2017

Aviation [through 18z Sunday]
Outside of a possible brief thunderstorm at kvld, dry andVFR
conditions are expected at all terminals through the forecast
period.

Prev discussion [1020 am edt]
Near term [through today]
Weak low-level boundary stretching from south-central georgia,
through the eastern big bend and into the northeastern gulf is
providing the focus for morning showers and storms. This area will
continue to be the focus through the early afternoon with the
highest pops in the area. Elsewhere, northerly low-level flow and
mid-level dry air (noted in the 12z ktae sounding) will limit
convective coverage this afternoon. Expecting isolated coverage
in the central big bend, with dry conditions elsewhere to the
northwest. Temperatures will be hot for most of the area, with
highs in the mid 90s.

Short term [tonight through Monday]
The upper level low will continue to push westward across our
area and the eastern gulf of mexico on Sunday, and into the
central gulf on Monday. As this occurs, increasing deep layer
moisture will get pulled northward into our area with
southeasterly flow. Pwat values will rise above 1.5" across
northern fl on Sunday afternoon and evening, and continue
increasing to around 2" on Monday. This will lead to more
widespread chances of showers and thunderstorms on Monday, while
scattered showers & storms will mainly be confined to northern fl
and south central ga on Sunday.

Given the ample moisture on Monday afternoon combined with moderate
instability, cloud cover should become fairly widespread as
scattered showers and thunderstorms develop across our area. As a
result, it may be difficult to see the solar eclipse. However, there
should be breaks in the clouds in some areas, and the decrease in
solar radiation during the peak eclipse time could cause some minor
temperature decreases across our area. As a result of this effect
combined with increasing cloud cover, high temperatures should be a
couple degrees cooler across our area on Monday than on Sunday. Hot
and very humid conditions will still persist each day, resulting in
maximum heat indices near 105 on Sunday and around 100 on Monday.

Long term [Monday night through Saturday]
As the upper level low that was discussed in the short term
section pushes farther southwest of our area across the gulf, deep
layer ridging will build across our area through Tuesday and
Wednesday. Ample deep layer moisture will persist throughout this
time, so scattered showers and thunderstorms remain possible each
day, with highest chances during peak instability times (afternoon
and early evening hours). Late in the week, an upper level trough
will deepen across the southeastern conus, and a surface trough or
weak front should push southeastward across our area on Thursday
and Friday. These features should enhance forcing for showers and
thunderstorms, although some mid-level dry air could limit
precipitation coverage during this time. As a result, kept pops
generally in the 40-50% range through this period. Hot and humid
conditions will prevail through this period as well, with apparent
temperatures expected to reach the lower 100s each afternoon due
to highs in the lower 90s and dewpoints in the mid 70s.

Marine
Light and variable winds around 10 knots or less will prevail
through the next several days, resulting in generally light seas
through next week.

Fire weather
Hazardous fire weather conditions are not expected through much of
the week outside of low dispersions in the fl big bend Sunday
afternoon. Chances for wetting rains will become more widespread
early next week.

Hydrology
Scattered showers and thunderstorms will increase in coverage next
week, but widespread heavy rain is not anticipated. Therefore, no
flooding is expected and rivers will likely remain below flood
stage.

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.
