1231 am est Thu jan 24 2019

Aviation
[through 06z Friday]
line of showers has weakened due to low instability as it has made
it from tlh and aby eastward to vld. Showers will end at dhn and
ecp in the next several hours. Winds have also decreased behind
the area of showers but are still gusty along and ahead of it. The
line will continue to progress eastward overnight and clear the
area in the morning. Winds will switch to the northwest and skies
scattering out towards mid late morning hours.

Prev discussion [837 pm est]
Near term [through tonight]
Gusty pre-frontal winds continue across much of the area at this
hour, with several locations along the panhandle coast (tyndall
afb & ecp) recording gusts around 40 mph in the last hour. Given
prime mixing conditions in place across much of the region, expect
windy conditions to persist into the evening and overnight hours
ahead of the expected approaching line of showers and storms.

Caution is urged through tonight, especially if traveling. High
profile vehicles will be susceptible to high winds gusts, as will
weakened trees and lightweight and or compromised structures.

Confidence remains high on the timing of showers and thunderstorms
moving across the region later this afternoon and into the overnight
hours. Pockets of unfiltered sunshine have been observed across the
region at points this morning and early this afternoon. This, along
with an increasing LLJ streaming moisture back into the area will
increase instability across the area. MLCAPE values of ~500 j kg are
currently being observed along and just ahead of the frontal axis,
currently located across E ms W al. 0 to 1km bulk shear on the order
of 40 to 50 kts along with favorable hodographs between 0-1 km will
yield the threat for a few strong to severe thunderstorms along and
ahead of the line this evening. Given the environment in place, a
few brief tornadoes are not out of the question. Given the threat
for severe weather to persist into the overnight hours, make sure
you have multiple ways to get warnings, even when asleep.

Short term [Thursday through Friday night]
The upper level vort lobe will sweep east of the area Thursday
morning with the cold frontal passage occurring before 12z. Any post-
frontal showers should exit east by 15z. That will set the stage for
a chilly period with highs on Thursday only in the 50s in most
areas, lower 60s south and east of perry, fl. Lows Thursday night
might briefly touch freezing north of an albany to dothan line with
other inland areas in the low to mid 30s. After another afternoon in
the 50s Friday, a widespread light freeze will occur for most inland
areas outside of urban centers. Remember, watches and warnings will
not be issued for this freeze as the growing season has ended.

Long term [Saturday through Wednesday]
The long-wave trough will remain in place across the eastern u.S.

Through this period as a series of short waves rotates through
it. Surface high pressure will keep things dry into early next
week. The next frontal system will push through Tuesday and
Tuesday night. It appears that the moisture will move out before
the cold air moves in per usual. The euro had been indicating the
possibility for some non- liquid precip with this system, but has
now come in line with the GFS and mo longer indicates this
potential, at least the operational run.

Marine
A gale warning remains in effect for frequent gusts, however
gale- force gusts should be over before daybreak Thursday. High
surf and rip current risk will continue well into Thursday as
well. Small craft advisory conditions will then continue into the
afternoon. Winds and seas will then remain below headline criteria
through the weekend.

Fire weather
Windy conditions will persist through the remainder of the day
across the region. However, rh's will remain above critical
thresholds. Wetting rains are expected later this evening through
the overnight hours. Drier conditions will prevail tomorrow, but
hazardous conditions are not expected.

Hydrology
Rain will move into the region this afternoon and with this system
fairly progressive, rainfall amounts should average in the 1-2 inch
range across the forecast area with isolated heavier amounts up to 3
inches possible. While these amounts do not present a flash flood
threat, they will result in some of the faster responding river
rising above action stage. Should amounts greater than 2 inches
occur within some of the smaller basins like the kinchafoonee,
ochlockonee and chipola, portions of these rivers could move toward
the minor flood category in the coming days.

The apalachicola river near blountstown will continue to remain
above flood stage for the next several days as releases down the
chattahoochee remain above normal.

For coastal flooding, strong southerly flow (and eventually
southwesterly flow) ahead of the approaching storm system will keep
water levels above normal throughout the next 18-24 hours especially
throughout apalachee bay. With this event, the surge component is
much higher than last weekend, but because the peak surge is more
aligned with the time of low tide (04z-05z), peak storm tide water
levels are not much higher than the event last weekend. Available
deterministic and probabilistic guidance shows peak storm tide
levels in the 2.5 to 3.5 ft mean higher high water (mhhw) range
between 04z-14z Thursday.

With the mean of all guidance less than 3 ft mhhw and any areas
greater than 3 ft mhhw being fairly isolated, will continue the
coastal flood advisory as currently configured geographically, but
extend it temporally to 15z Thursday.

Spotter activation is not requested. However, spotters are always

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
