area forecast discussion
national weather service tallahassee fl
931 pm edt Sat mar 25 2017

Near term [through tonight]
00 utc surface analysis shows an area of low pressure across
central missouri with an associated frontal zone extending down
the mississippi river and into southwestern louisiana. Convection
was occurring well ahead of the frontal boundary. Limited
southerly flow ahead of the system has resulted in weak moisture
return across much of our region as dewpoints this evening across
the eastern florida panhandle and into the florida big bend are
in the upper 50s inland to the lower 60s at the coast.

The 00 utc ktae sounding shows that while the subsidence inversion
has weakened since the previous 12 utc launch, the local airmass
is still relatively stable and appreciably dry with a precipitable
water value of 0.81 inches. Thus, as the current line of
convection continues to progress eastward, it will encounter a
progressively hostile airmass that will likely facilitate further
weakening. In fact, most of the guidance shows the area of storms
diminishing before reaching tallahassee.

Based the latest guidance and radar trends this evening have
updated the pops primarily west of the apalachicola/chattahoochee
rivers, but maintained the sharp gradient to the east. Convection
is running a little further ahead of the latest ecam guidance, so
will keep some potential of rain making it along an albany to
tallahassee line - but not much further east than that.

Prev discussion [731 pm edt]
Short term [Sunday through Monday night]
The front across the southeast will weaken and lift northward on
Sunday as the low pressure system the front is associated with
lifts into the midwest and towards the great lakes, however a few
showers and thunderstorms will still be possible on Sunday. While
cape values of 600 j/kg support thunderstorms on Sunday, low
level and deep layer shear are on the lower side. With this and
the fact the upper level feature is well removed to the north of
the cwa, severe storms are not expected on Sunday. The surface low
will move into the great lakes Sunday night into Monday, with the
weakening cold front lifting north and east, providing a lull in
precip Sunday night into Monday morning. Another low pressure
system will track from the southern plains Sunday night into the
tennessee valley Monday night, however the main portion of the
precip associated with this surface low will remain north of the
cwa.

High temperatures will be in the mid 70s to lower 80s on Sunday
with the upper range increasing into the mid 80s Monday. Lows will
range from the upper 50s to the lower 60s.

Long term [Tuesday through Saturday]
While a few showers and thunderstorms will be possible across the
northern portion of the CWA near the beginning of the long term,
the best chance of precipitation will be with a front moving
through on Friday. This will bring a return of rain chances to the
chance range with precip diminishing for the weekend. High
temperatures will increase into the mid to upper 80s for Wednesday
and Thursday and return to the upper 70s to lower 80s late in the
week with the additional coverage and rain and behind the front on
Saturday. Lows will mainly be in the upper 50s to lower 60s.

Aviation
[through 00z Monday] a weakening squall line will move into the
area from west to east this evening and into the overnight hours.

Mainly MVFR conditions are expected with this line at dhn and ecp,
but short periods of ifr are possible in heavier rain. As the line
continues to weaken, it will move across aby and tlh, but scattered
showers may not be intense enough to produce significant visibility
restrictions. After any showers end, some patchy fog is possible
across our area during the early morning, but visibility is likely
to remain atVFR through the remainder of the period.

Marine
Winds and seas will diminish tonight and remain below cautionary
levels into early next week. A storm system will increase the
chance of showers and thunderstorms tonight with chances
diminishing on Sunday. Another front late in the week, will
increase winds and seas to at least cautionary levels.

Fire weather
Red flag conditions are not expected for the next several days with
relative humidity values remaining above critical levels.

Hydrology
Rain is expected tonight, but amounts will be on the lighter side
with a half inch to an inch west of a panama city to dothan line
and generally around a quarter inch or less along and east of this
line. These amounts are not expected to cause any significant
flooding on rivers.

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.
