Area Forecast Discussion
National Weather Service Tallahassee FL
734 AM EDT Fri Apr 26 2019

.UPDATE...

No significant changes to the previous forecast appear necessary.
Showers and thunderstorms have mostly exited the area this morning
with clearing skies expected for the remainder of the day.

&&

.AVIATION...

[Through 12z Saturday] A variety of restrictions exist across the
terminals this morning in fog and low clouds, down to LIFR at at
times for all sites outside of VLD, where MVFR to IFR is expected.
VFR conditions will return in the late morning hours. Winds will
veer to a more northwesterly direction by late morning and increase,
with gusts around 20 kt.

.PREV DISCUSSION [433 AM EDT]...

.NEAR TERM [Through Today]...

A cold front will gradually move eastward across the region early
this morning. Thundershowers mainly east of a line from roughly
Valdosta to Apalachicola will gradually subside. Cannot rule out
localized gusty winds with this activity, however the threat of
severe weather is decreasing, and will be marginal at best. After
mid-morning, expect a gradual clearing trend as northwest flow
introduces subsidence in the column, ushering in a much drier air
mass. The mixed layer will extend up to around 900 hPa today,
and based on winds within this layer, expect gusts around 20 to
25 mph at times. High temperatures will range from the upper 70s
to lower 80s, with noticeably less humidity!


.SHORT TERM [Tonight Through Sunday]...

The upper level pattern will deamplify tonight as the trough lifts
away to the northeast. Zonal flow will be in place for the weekend.
Surface high pressure will build eastward across the Deep South
through the period. The result will dry weather and be seasonal
temperatures. Look for lows mainly in the lower to mid 50s (warmer
near the coast) and highs in the upper 70s to lower 80s.


.LONG TERM [Sunday Night Through Friday]...

As an upper trough deepens out west, deep- layer ridging will
occur over the Southeast. The surface ridge will begin to weaken
by midweek with the upper ridge sliding southeastward. Some weak
return flow will allow slight to low chances of showers and storms
to return to the forecast for Wednesday and Thursday.
Temperatures will be above normal through the period with highs in
the upper 80s inland, lower 80s near the coast. Morning lows will
be in the mid to upper 60s.


.MARINE...

Moderate northwest winds will shift to the east and weaken by
Saturday with light winds and low seas for the most part into the
middle of the week.


.FIRE WEATHER...

Thundershowers are possible across the eastern big bend into the
I-75 corridor of Georgia early this morning, followed by much
drier conditions the remainder today and especially on Saturday.
Transport winds around 25 mph today will lead to high dispersions
across much of the area. Despite the high transport winds,
relative humidity values should remain above 30 percent. On
Saturday, relative humidity levels will dip into the low to mid
20s during the afternoon, but transport winds will be less than 10
mph. Therefore, red flag conditions are not expected today or
Saturday.


.HYDROLOGY...

Storm-total rainfall was generally 1-1.5 inches with some higher
amounts around 2 inches near the coast. The Apalachicola River at
Blountstown will drop below flood stage this afternoon. The
Ochlockonee River in GA will crest near or just above action stage
from Saturday through Monday.


.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.
