area forecast discussion
national weather service tallahassee fl
838 pm edt Sun may 26 2019

Update
Isolated showers developed on the sea breeze and boundary
collisions this afternoon. Due to the stacked high pressure
overhead, the showers were shallow and short lived. All convection
has since dissipated. It was another hot one today with albany
leading the way with a high of 101 degrees. This tied the record
set back in 1962. Tonight's low temps will only be in the lower
70s.

Prev discussion [746 pm edt]
Near term [through tonight]
The abnormally strong 500mb ridge remains in place aloft of the
tri-state area today, though it is gradually weakening. This is
allowing for the very hot temperatures across the area to
continue. Temperatures are expected to continue to warm this
afternoon and peak in the upper 90s with heat indices up to 106 in
spots. Overnight, temperatures will fall into the low 70s.

Short term [Monday through Tuesday night]
The large scale pattern will remain more or less in place over the
area, with high pressure continuing to dominate the forecast over
the southeast conus. What will change things up slightly is that
gulf moisture will gradually build up over the area, bringing a
return for a slight chance of showers and thunderstorms by
Tuesday. This 20% pop will be mostly focused over the fl big bend
and in south central ga, where this increased moisture, combined
with the seabreeze front and instability from the warm inland
temperatures, could be enough to generate scattered storms. Highs
will remain above normal, peaking in the upper 90s over much of
the area, with heat indices in the 100-105 range.

Long term [Wednesday through Sunday]
A series of +pv anomalies will roll through the longwave upper
level trough over the western and midwestern states. By Friday,
this is expected to finally break down and push eastward the ridge
of high pressure that's been in place over the southeastern
conus. These upper level disturbances are expected to bring a
weak cold front toward the area around Friday-Saturday, then
exiting Sunday. There won't be much energy left with this system
by the time it gets here, so kept pops low for now (around
20-30%). Highs will continue to be in the 90s with lows in the
low-mid 70s.

Aviation
[through 00z Tuesday]
vfr conditions will prevail with light winds.

Marine
High pressure over the coastal waters will render light winds and
low seas through the period. Chances for showers and thunderstorms
will return Friday.

Fire weather
A very dry air mass is in place with relative humidity values mostly
between 30 to 35 percent across inland areas at least through
Tuesday. Fuels are also dry in most locations. Red flag criteria
will not be met since winds will be light and relative humidity
values are not quite low enough.

Hydrology
River levels are low due to the dry spell. The next chance for
widespread rain will be on Friday.

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.
