area forecast discussion
national weather service tallahassee fl
153 am edt Sun oct 22 2017

Aviation [through 06z Monday]
With the exception of a temporary period of MVFR ceilings at aby
and vld in the morning,VFR should prevail at all terminals
through the taf. Scattered to broken low level clouds should be
expected today along with isolated showers tstms mainly across
north florida and SE al.

Prev discussion [925 pm edt]
Near term [through tonight]
At upper levels, the ridge will remain parked off the southeast u.S.

Coast and move little as an upstream trough deepens across the great
plains. Surface high pressure centered over the mid atlantic states
will slide a bit further to the east as winds on its southern
periphery veer slightly from the ene to the ese over our forecast
area. Isolated showers will move west from the atlantic overnight,
but are not expected to reach as far east as out zones. However,
some lower clouds are expected to make it into our ga zones. It will
be another mild night with lows generally in the mid 60s.

Short term [Sunday through Monday night]
Deep layer moisture will increase from Sunday through Monday
morning as southeasterly to southerly flow brings a warm, moist
airmass northward from the gulf into our area. Pwat values are
expected to exceed 1.5" by Sunday evening, and will increase to
around 2" on Monday morning. Throughout this period, a sharp upper
level trough will move eastward toward our area, with a well-
defined cold front also pushing eastward under the leading flank
of this feature. As a result of the increasing moisture and
forcing, rainfall will become more likely from west to east on
Sunday night, with periods of showers expected from Monday morning
through the afternoon. Isolated thunderstorms are also possible,
although thunderstorm coverage and intensity could be limited by
modest instability. However, SBCAPE could increase to 500-1500
j kg along and just ahead of the front on Monday late morning and
afternoon, with ample 0-6 km bulk shear (40 kts or greater)
present due to the potent trough moving into our area. As a
result, severe thunderstorms cannot be ruled out during this time.

Chances of showers and storms will decrease from west to east on
Monday night as the front continues to push eastward, and in its
wake much cooler and drier air will push into our area. Highs will
be in the mid-upper 80s on Sunday with lows in the upper 60s and
lower 70s Monday morning. After highs ranging from the upper 70s
northwest to mid 80s southeast on Monday, temperatures will drop
into the 50s overnight across most of our area.

Long term [Tuesday through Saturday]
Much cooler and drier air will continue to settle in across our
area behind the cold front mentioned in the short term discussion.

As high pressure builds across our region from Tuesday through
Thursday, generally clear skies will prevail each day. Highs will
remain in the 70s, with some inland areas possibly remaining in
the upper 60s on Wednesday as a secondary cold front pushes across
our area. Under ideal radiational cooling conditions, lows will
dip to the mid-upper 40s inland on Wednesday and Thursday morning.

Late in the week through the weekend, increasingly mild and moist
conditions will return to our area ahead of another potent upper
level trough approaching our area. Chances of showers and
thunderstorms will increase on Saturday as the leading edge of
this upper trough moves into our region and another cold front
approaches our area. Highs in the upper 70s and lows in the 50s
are expected from Friday through Saturday.

Marine
Increasing easterly winds tonight will result in choppy seas and
advisory level conditions across all but our eastern nearshore
zones. Small craft will need to continue exercising caution
through early next week as a cold front moves across our area,
resulting in persistent elevated winds and choppy seas.

Fire weather
Hazardous fire weather conditions are not expected over the
next several days. Rain is expected on Sunday and especially
on Monday with an upcoming frontal passage.

Hydrology
Coverage of showers and isolated thunderstorms will increase from
Sunday evening through Monday as a cold front moves into our
area. Widespread amounts from 1 to 2 inches are expected across
our area, with isolated totals up to 3 inches possible. These
amounts are unlikely to cause widespread flooding.

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.
