area forecast discussion
national weather service tallahassee fl
134 am edt Wed apr 25 2018

Aviation [through 06z Thursday]
Vfr conditions will continue through the remainder of the period
with only a few scattered mid-high level clouds expected at all
terminals. Light west-northwesterly winds early this morning will
approach 10 knots from the late morning through early evening,
then become light again tomorrow night.

Prev discussion [826 pm edt]
Near term [through tonight]
Low pressure area is situated the carolinas with an expansive area
of cloud cover wrapping around the backside across the southeast us.

There is some convective elements embedded in the overall CU field
so slight chance pops this afternoon across our western counties is
maintained. This area is supported by a weak mid level trough which
will rotate through the area this evening. Behind this feature,
low mid level rh begin to decrease so cloud cover should slowly wane
overnight. Lows will fall into the mid to upper 50s.

Short term [Wednesday through Thursday night]
The upper low currently meandering over tn ky this afternoon will
be kicked poleward by a shortwave trough emerging from the
northern rockies. This will yield dry conditions for Wednesday,
with this system approaching the region from the northwest on
Thursday, bringing with it a chance for rain across mainly
southern alabama and georgia. The latest model guidance continues
to indicate sufficient moisture, instability and shear to support
a few thunderstorms Thursday afternoon evening. Though deep layer
shear will be 35 to 40 knots, limited instability will keep
severe storm chances low. It is worth noting that shear profiles
with this upcoming system look unidirectional, which is not
conducive for any rotating storms or tornadoes. Temperatures will
remain seasonal through the period, with highs in the upper
70s low 80s and lows in the upper 50s to low 60s.

Long term [Friday through Tuesday]
The system discussed in the short term period will lift poleward
out of the region Friday morning, giving way to another shortwave
trough approaching from the west. The GFS and it's ensemble
members are bullish on pops this afternoon compared to other
guidance, as moisture content will be a big question mark as this
system approaches. As a result, kept pops low for this period, as
any showers that may develop will likely be sparse in nature.

Quasi-zonal flow will prevail through the end of the period,
yielding dry and seasonal conditions.

Marine
West to northwest winds around 15 knots will with 2 to 3 foot seas
will prevail through Wednesday afternoon before gradually
decreasing through this weekend.

Fire weather
Red flag conditions are not expected over the next few days, though
dispersion indices are forecast to be marginally high.

Hydrology
The next chance of rain will come on Thursday, with a few heavier
showers possible, mainly across our northwestern areas. However,
rain totals should remain well under 1" for most areas, with dry
conditions through the remainder of the period. As a result, no
flooding is expected through the next several days.

Spotter information statement
Spotter activation is not requested. However, spotters are always
encouraged to safely report significant weather conditions when they
occur by calling the office or tweeting us @nwstallahassee.

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.
