AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TALLAHASSEE FL
1008 AM EST SUN FEB 14 2016

.Update...

No updates were necessary to the forecast for the remainder of the
day. Previous discussions are below.

&&

.Prev Discussion [624 AM EST]...

.Near Term [Through Today]...
The 10 pm EST regional surface analysis showed an area of high
pressure and a cool, dry airmass across the Southeast. As the center
of the high translates quickly eastward across the Northeast later
today, boundary layer moisture will slowly begin to increase across
our forecast area. We expect mostly sunny skies today with highs in
the upper 50s from Dothan and Albany northward, to mid 60s in
northwest FL.

.Short Term [Tonight Through Tuesday]...
A developing storm system across the Southern Plains will begin to
move toward the Gulf Coast States tonight as low level
southeasterly flow increases across our region. Models seem to be
settling toward an overall less amplified solution with the mid
level trough driving the system eastward. While intensity with
this system has been uncertain over the last few days, the models
have had a good handle on the timing of rain with this system, as
that has changed little over the last several forecast cycles.

By Monday, moisture will be on the increase during the day, and
extensive cloudiness is likely, limiting the degree of
destabilization ahead of the system across our region. Moreover,
the low level flow should maintain an easterly component til late
Monday afternoon - limiting a better return of moisture-rich air
from the Central Gulf. As a result, the airmass ahead of the
system is expected to be only marginally favorable for any
thunderstorms. Model soundings suggest modest elevated
instability will be present, but surface-based instability is
limited - likely only confined to areas along and south of the
I-10 corridor in the Florida Panhandle. Coupled with a weaker mid
level trough, deep layer shear is not overly impressive, generally
40 to 45 knots. Thus, these factors combined, as the storm system
moves through late Monday afternoon and into the overnight hours,
suggest a marginal risk for severe storms.

With the system moving through quickly Monday night, clearing
conditions on Tuesday are expected. Little in the way of cooler
air will move in behind this system, so high temperatures on
Tuesday could warm into the lower 70s under mostly sunny skies.

.Long Term [Tuesday Night Through Sunday]...
A quiet stretch of days is expected during the long term period.
A dry cold front will move through the region on Wednesday, only
dropping temperatures a couple degrees. By Thursday and beyond,
surface and mid level ridging will build over the region and
afternoon temperatures will warm a couple of degrees each day
into the weekend, when highs will likely reach the mid to upper
70s. Overnight lows will still be cool, in the low to mid 40s,
given the airmass will stay relatively dry.

.Aviation...

[Through 12Z Monday] VFR conditions will continue through this
evening. NE winds 5 to 10 KT will gradually veer to the E then SE
this afternoon. Several sets of NWP guidance forecast fog and/or
low cigs late tonight and early Monday, and the GFS does show
some high RH values and weak low-level isentropic ascent to
support this. We have introduced some lower cigs and Vis (low-end
MVFR) across much of the region toward dawn Monday. These values
will be fine-tuned in subsequent TAF packages.

.Marine...
Moderate easterly flow today will shift to southerly ahead of an
approaching storm system on Monday. Cautionary conditions are
expected during this time, with a period of advisory level winds
possible Monday evening as the storm system moves through the
region. Lighter winds and lower seas are expected Tuesday and
through the remainder of the week as high pressure stays near the
marine area.

.Fire Weather...
Although boundary layer moisture will gradually increase this
afternoon, RH values in southeast AL and the FL Panhandle may reach
local critical thresholds. However, the duration of this low rh,
wind speeds, and ERC values will not support Red Flag conditions.

.Hydrology...
Releases from Woodruff Dam have stabilized around 40kcfs and are
planned to stay at that level for another 24 hours before
decreasing. As a result, minor flooding at Blounstown should
continue into early Monday.

Rises continue through the lower portion of the Middle Suwannee
River Basin and further downstream into the lower stretches of the
river. Only the US-19 crossing near Fanning Springs should reach
action stage around 2/18.

Rainfall with Monday's storm system is expected to be heaviest
across the western half of the region where 1-1.5 inches of rain
is anticipated with lighter amounts further east. These amounts
will cause some modest rises on area rivers, with the most likely
areas for any river flooding (minor) to be across the Lower
Choctawhatchee River below Caryville.
