Aviation [through 12z Saturday]
Currently we have MVFR CIGS at dhn and MVFR CIGS will be possible
at tlh, ecp and vld until around 15z. Thereafter, expectVFR
conditions with light east to southeast winds.

Prev discussion [307 am edt]
Near term [through today]
A west to east oriented ridge will remain centered over southern
florida. Meanwhile, surface high pressure centered over the mid-
atlantic states will slide eastward as a cold front drops
southeastward from the midwest into the tennessee valley by tonight.

Temperatures will be a few degrees warmer today along with a bit
more humidity as low level flow veers to become more easterly. Highs
will range from the lower 80s for our northern zones to the mid
and upper 80s elsewhere.

Short term [tonight through Sunday night]
A broad upper ridge encompassing much of the southern states and
gulf of mexico will weaken as an upper trough digs down from the
north. A cold front will be stretched from tx up through nj
overnight but the local area should stay dry with lows in the mid to
upper 60s.

The cold front will continue to move southeast on Saturday but most
of the moisture and lift will be gone by the time it reaches SE al.

This will lead to just isolated showers for most of the area with
higher chances in SE al. Highs will remain in the lower to upper
80s. The good news is that even without the lift, the drier and
cooler northwest flow will actually make it through the region by
12z Sunday. So the lows Saturday night will be much cooler; in the
lower 50s inland to the lower 60s along the coast. As heights
continue to lower, Sunday will be dry and could feel downright
cold! With highs ranging from the upper 60s inland to the lower
70s on the coast, it will be the coldest day we've seen since
early april. Then, heading into Sunday night lows will be
dropping into the middle 40s to around 50 degrees (not a typo).

Normal highs in october are in the upper 70s low 80s and normal
lows are in the upper 50s.

Long term [Monday through Friday]
Behind the departing front and upper trough, high pressure quickly
builds in leaving Monday with heights rising and winds turning
more easterly. Temps will warm slightly with highs in the mid 70s
and lows in the upper 50s lower 60s. A weak upper disturbance
moving off the east coast of tx will bring moisture into the area
via westerly winds aloft on Tuesday. Chances of rain start to
increase, mostly in areas south and west of tallahassee Tue into
tue night. High pressure builds south on Wednesday, with
subsidence keeping pops around 20% although cloud cover will be on
the increase ahead of the next system. Temps will also be rising
with highs Tue in the mid 70s and then upper 70s on wed. Guidance
is showing a dry cold front moving through on Wed although the
signal is very faint. At most, it lowers highs on Thursday a few
degrees.

The pattern as we get into Thursday and Friday looks much wetter
with some significant differences this far out. Looks like the
previous frontal boundary gets somewhat stuck between a ridge to the
south and zonal flow aloft to the north. This keeps a steady stream
of weak low pressure areas moving west to east Thursday into Friday.

Superblend pops were about 90% so have brought those back down to 50-
60% for now due to the uncertainty.

Marine
Winds remain around 5 to 10 knots through Saturday with seas of 2
to 3 feet. A cold front will move through Saturday night and
increase winds over the waters to 15 to 20 knots and seas up to 6
feet are possible. Winds and seas lower Monday through Tuesday
behind the front but remain elevated.

Fire weather
Due to light transport winds, afternoon dispersion indices will be
low today. Otherwise, there are no other fire weather concerns.

Hydrology
No hydrology impacts are expected through the next five 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.

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.
