area forecast discussion
national weather service tallahassee fl
1009 am est Sat feb 23 2019

Update
No significant changes to the previous forecast appear necessary.

It will be another very warm february day with high temperatures
near their daily record values in the low to mid 80s away from the
coast. The official forecast high of 83 for tallahassee would tie
the record for the day.

Prev discussion [615 am est]
Near term [through today]
Dense fog advisory continues for areas adjacent to the coast. For
the most part, dense fog has been patchy at best with most of the
area just having low clouds. Dfa is set to expire by mid morning.

Clouds will be slow to break today so nudged highs down slightly
but record highs will be threatened with a record high of 83 for
tallahassee. Highs are expected to be in the low to mid 80s. A
shower or two cant be ruled out and favor our ga counties.

Short term [tonight through Monday]
Cold front will approach the area tonight then sweep through
Sunday. A line of showers and isolated thunderstorms will be
possible along the front. Shear is good but instability is less
than 500 j kg so and isolated severe storm is not out of the
question. SPC has highlighted just a sliver of SE al in a marginal
risk for severe weather. Rainfall amounts will average one half
inch or less. Once the front moves through, cooler and drier
conditions will move in. Highs will be nearly 15 degrees cooler
Sunday and Monday as compared to Saturday.

Long term [Monday night through Saturday]
Cooler temperatures will continue into the long term period as
high pressure moves through the midwest. Highs will be in the
upper 60s to lower 70s. Once the high moves to the east coast,
the cold front will begin moving back towards the coast as a warm
front. Conditions become unsettled mid week into the weekend as
the warm front moves through the area then a series of low
pressure systems and cold fronts move through the area. Confidence
is low as solutions between the models continue to diverge.

Aviation
[through 12z Sunday]
degraded flt conds just about everywhere across the tri-state
region this morning. More so low CIGS over low vsbys but
regardless lifr conds at most of the TAF sites this morning with
the exception of vld. That will change over the next hour as low
cigs are moving in from the east. Expect these conds to persist
through mid morning. Conds will improve back toVFR by late
morning into the early afternoon. Another round of degraded flt
conds is expected this evening into overnight with a cold front
and shra tsra expected to arrive after this TAF period.

Marine
Dense fog will continue across the nearshore waters through this
morning. Generally light to moderate winds will prevail today with
a cold front expected to move across the gulf waters Sunday.

Winds will increase to cautionary levels Sunday then advisory
levels Sunday night into Monday. Conditions gradually improve into
the middle of next week.

Fire weather
Aside from possible high dispersions today, there are no other fire
weather concerns.

Hydrology
Local river levels are steady or falling and mostly below action
stage. Forecast rain totals for the next five days are 1 2 inch or
less.

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.
