Area Forecast Discussion

325 PM EDT TUE JUL 28 2015

.Near Term [Through Tonight]...

The expectations of a hot day are panning out this afternoon, with
19Z temperatures mostly in the mid to upper 90s (slightly cooler in
the eastern Florida Big Bend). Most locations should see their high
temperatures in the next hour or two, with a relatively warm night
expected tonight. The normal low for Tallahassee is 72, but lows
tonight are expected to be in the mid-70s (77 at TLH). Isolated
convective activity has developed in the northwest parts of the
area, and some isolated showers and storms will continue to be
possible into the early evening hours (but should generally diminish
around sunset).

.Short Term [Wednesday Through Thursday Night]...

In general, we`ll remain under the eastern periphery of middle and
upper level ridging through the short term. At the surface, broad
low pressure will dominate.

Under the current ridge position, northerly steering flow will
advect any MCV or MCS from the east-central CONUS, south into the
Tri-State region. The current thinking advertises some scattered
storms in our Georgia counties tomorrow morning, resulting from
convection ongoing over the Ohio and Tennessee Valleys. Later in
the day, through the evening, a larger storm complex will likely
dive through the region. This round is most likely generated from
the remnant MCV from convection in the Upper Mississippi Valley
this afternoon. Essentially this means that the 8am - 12am period
Wed. into Thurs. will be quite wet. This should also keep
afternoon highs in the lower to middle 90s.

On Thursday, the broad area of surface low pressure will center
itself closer to the Tri-State region, increasing low-level
convergence. This will likely force widespread thunderstorms under
a more typical diurnal cycle. The widespread nature of storms will
most likely continue to keep high temperatures in the lower 90s.

.Long Term [Friday Through Tuesday]...

Beginning Friday, the upper ridge moves a bit further east with
eastern CONUS troughing bulging into the Southeast. At the same
time a surface front will settle into the region and stall. This
will keep rain chances above normal through the weekend. Early
next week a shortwave will dive into the southeast, keeping above
normal PoPs in the forecast. Afternoon highs will remain near, to
slightly below normal.


[Through 18Z Wednesday]

VFR conditions are expected to prevail through the TAF period.
Storms this afternoon and evening are expected to be isolated, so
terminals may not be affected. If one of the terminals is affected
(ECP and DHN would be most likely), brief IFR visibilities would
be possible.



West/southwesterly winds will prevail through the next week and
will likely remain below headline levels. Shower and thunderstorms
are expected each day.


.Fire Weather...

Hazardous fire weather conditions are not expected as we
transition back to a pattern of unseasonably high PoPs.



Rain chances will steadily increase as the week progresses. Five day
rain totals are estimated to be 3 to 4 inches near the Florida
coast, particularly the Big Bend. Elsewhere, 1 to 2 inches is
likely. Area rivers are still below action stage. With the heaviest
rainfall expected near the coast, river flooding is not expected.
