area forecast discussion
national weather service tallahassee fl
615 am edt Tue oct 22 2019

Aviation
[through 12z Wednesday] mainly MVFR to ifr conditions will prevail
through the morning hours as a cold front moves through, although
ecp may stay mostlyVFR. Conditions will improve toVFR from west
to east through the day with dhn expected to becomeVFR by mid to
late morning.

Prev discussion [327 am edt]
Near term [through today]
A cold front will push rapidly through the area today. Scattered to
numerous showers are expected ahead of it this morning across
portions of southwest georgia and the florida big bend. Instability
appears limited, so only a slight chance of thunderstorms is
expected near the coast. Clearing skies are expected from west to
east this afternoon behind the front. High temperatures are expected
to range from the mid 70s across southeast alabama behind the front
to the mid 80s across the far southeast big bend ahead of the
front.

Short term [tonight through Thursday]
Dry air will be in place across the entire region by the start of
the period as the cold front will be draped to the south and the
east of the area. Temperatures tonight will fall into the upper
40s and low 50s as a result, which is actually around normal for
late october. Pleasant weather will persist through Wednesday as
the region remains under quasi-zonal flow. Afternoon high
temperatures will run in the low 70s. The aforementioned cold
front will start to lift northward as a warm front on Thursday in
response to a shortwave trough diving out of the central rockies.

As a result, temperates will rise once again along with cloud
cover and rain chances, generally across the florida panhandle and
southern alabama wiregrass.

Long term [Thursday night through Tuesday]
Considerable uncertainty remains regarding the pattern and the
resultant weather for the tri-state area from Friday onward.

Operational guidance and associated ensembles remain split between
two different solutions. The operational ECMWF and canadian for what
its worth continue to cut off a an upper low over west texas eastern
new mexico, even further west than previous runs. The GFS and gefs
ensembles continues to swing an upper low through the region,
yielding widespread chances for rainfall. General model blends tend
to favor slower more western solutions regarding pops, thus will
continue to favor these in the official forecast with this package.

Friday and Saturday look wet and active, while Sunday through early
next week generally look mostly dry. As mentioned previously, there
remains considerable uncertainty in the overall pattern, so changes
in the forecast are possible as we move through the week. Increased
cloudiness will yield average high temperatures (upper 70s to near
80) and warm overnight lows (low to mid 60s) across the region
through the period.

Marine
Winds and seas will remain at cautionary levels today and will
persist through much of the remainder of the week. Chances for
showers and thunderstorms will be on the increase Thursday into
Friday. Scattered storms will remain possible over the weekend.

Fire weather
A fairly dry airmass will prevail across the area behind a cold
front late this afternoon into Wednesday, but relative humidity
values are expected to remain above critical levels. Increasing
moisture is expected again for late in the week through the weekend.

Hydrology
Another round of showers and storms is expected again later this
week. High uncertainty remains regarding amounts at this time. At
this time, the official forecast through the next week generally has
rainfall totals at 0.5 to 1.5 inches.

Spotter information statement
Spotter activation is not requested. However, spotters are always
encouraged to safely report significant weather conditions when they

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.
