Heavy rainfall possible through Tuesday for inland southeast
georgia and the western suwannee valley...

Currently
Late afternoon surface analysis depicts weak surface low pressure
centers (1015 millibars) centered near lake seminole in
southwestern ga and also just northeast of nc's outer banks.

Meanwhile, atlantic high pressure centered near bermuda is
extending its axis across central fl. Aloft... A col region is in
place over inland southeast ga, the fl big bend and the northeast
gulf of mexico in between ridges centered over deep south tx and
near bermuda. Elsewhere, a shortwave trough is progressing
eastward across the ozarks and the mid-mississippi valley. Strong
low level convergence associated with the surface low near the
fl ga border west of our area continues along the fl big bend,
with a saturated air mass featuring pwats of 2.1-2.4 inches
persisting locally. Bands of mainly low-topped convection continue
to migrate northeastward from the surface circulation across the
suwannee valley and southeast ga, while locations south and east
of the i-10 corridor in northeast and north central fl have dried
out this afternoon as a more subsident air mass provided by
atlantic ridging lifts slowly northward from the fl peninsula. A
tighter pressure gradient on the east side of the low pressure
area is resulting in storm motion of 15-20 knots, which has kept
rain totals lower when compared to the previous few days. Highs
generally climbed to the mid and upper 80s this afternoon, except
a few lower 90s along the altamaha ocmulgee rivers earlier before
convection arrived. Dewpoints were mostly in the 70-75 degree
range as of 21z.

Near term (this evening through Monday)
Weak low pressure will meander northward along the chattahoochee
river valley, while the shortwave trough currently moving through
the ozarks crosses the tn valley overnight and then dives into
ga. This shortwave trough will amplify the overall pattern over
our region as ridges remain in place near bermuda and over west
tx. Short-term, high resolution guidance indicates that late
afternoon and early evening convection, mainly over locations
north of a line from gainesville to st. Augustine, will fade
before midnight, followed by a new burst of convection developing
near our far west and northwestern counties near the ocmulgee
river and the western suwannee valley towards sunrise as the
trough digs into our region from the northwest. Plenty of
cloudiness and low to mid level southwesterly flow will keep lows
in the low to mid 70s, except mid to upper 70s at coastal
locations.

The convective burst progged to develop near our western counties
should provide for widespread showers and embedded thunderstorms
on Monday morning for inland southeast ga and the western
suwannee valley, and we placed categorical pops in the forecast
grids for locations west of a line from alma to waycross to live
oak. Heavy rainfall will be possible at these locations, and
outflow boundaries from this activity should migrate eastward and
should encounter the inland moving atlantic sea breeze boundary
positioned along or just west of i-95 by late afternoon, resulting
in scattered to numerous showers and thunderstorms for most
locations east of u.S. Highway 301. Locally heavy rainfall,
frequent lightning strikes and briefly gusty winds will be the
main threats with any stronger convection that develops, as north-
northeasterly storm motion will be slightly slower (10-15 knots)
than today. Localized flooding may be realized over our western
and northwestern counties if another round of convection develops
during the afternoon hours, but confidence in placement and
durations of the heavier convective bands developing to the east
and southeast of the surface low remains too low to issue a flood
watch at this time. Cloud cover and persistent convection should
keep highs in the low to mid 80s over the northern suwannee valley
and most of inland southeast ga, while a diurnal mode to
convective development elsewhere allows highs to climb to the
upper 80s to around 90.

Short term (Monday night through Wednesday night)
Additional convective bands associated with the southern surface
low may rotate into our northwestern counties on Monday night as
this weak feature only slowly lifts northward along the ga al
border. Otherwise, evening convection developing along or east of
u.S.-301 in northeast and north central fl may push into coastal
locations before dissipating or moving offshore by the mid-evening
hours. Locally heavy downpours will remain possible for locations
west and northwest of a line from homerville to waycross to alma.

Lows will again only fall to the low to mid 70s for inland
locations and mid to upper 70s at coastal locations.

There remains some uncertainty on how quickly the surface low will
weaken over southern central ga on Tuesday, and locally heavy
downpours may persist over our far western northwestern counties
depending on how quickly atlantic ridging builds into our region
from the east and southeast. An overall loose pressure gradient
will result in faster inland progression of the atlantic sea
breeze boundary, which should be the focus for scattered to
numerous afternoon and evening showers and thunderstorms as a
surge of slightly higher pwats advects northward from the fl
peninsula late in the day. Temperatures aloft will remain
relatively mild, with locally heavy downpours, frequent lightning
strikes and briefly gusty winds expected within any convection
that pulses due to mesoscale boundary collisions or cell mergers
during the afternoon and evening hours. Highs should climb to the
lower 90s at most locations, except upper 80s near the
altamaha ocmulgee rivers and the western suwannee valley where
morning cloud cover will be more prevalent and also along the
atlantic coast, where the sea breeze will move onshore shortly
after noon.

Deep-layered ridging will then begin to build eastward across the
southeastern u.S. By midweek, pushing the weakening surface low
northeastward into the carolinas. This feature will possess a
weak trailing surface trough that will be pushing towards coastal
southeast ga and through northeast and north central fl, which
should be enough to ignite scattered to possibly numerous showers
and thunderstorms during the afternoon hours. Light west-
southwesterly steering flow could result in slow storm motion and
locally heavy downpours as activity developing over inland
locations encounters mesoscale boundaries such as the atlantic sea
breeze boundary. Highs will generally climb to around 90 before
convective coverage increases during the afternoon hours. Activity
may drift towards coastal locations on Wednesday evening and
should move offshore by the mid-evening hours, with some
redevelopment expected by sunrise on Thursday over the fl big bend
and possibly the western suwannee valley as the southwesterly low
level flow pattern persists. Lows in the low to mid 70s will
continue inland, with mid and upper 70s expected at coastal
locations.

Long term (Thursday through Saturday night)
Deep-layered atlantic ridging will sink south of our region by
late this week as a trough digs southeastward from the great lakes
into the mid-atlantic states and new england. Flow aloft will
briefly become west-northwesterly on Thursday, with a lingering
and slowly weakening low and mid level trough prevailing over
coastal northeast fl and inland north central fl. Flow aloft will
then veer to westerly on Friday and then southwesterly by early
next weekend as the trough bottoms out and then lifts east of new
england, with a surface frontal boundary stalling over the
savannah river valley late this week. A rather loose local
pressure gradient will continue, with mesoscale boundaries such as
the inland moving atlantic and gulf coast sea breezes being the
focusing mechanisms for scattered diurnal convection. Highs will
range from the upper 80s at coastal locations to the lower 90s
elsewhere, with lows in the 70s inland and near 80 at area
beaches.

Aviation
Convection is expected to impact ssi through around 23z, with
periods of showers and possibly an embedded thunderstorm at gnv
and the duval county terminals through around 23z. Dry weather
will prevail through at least 16z Monday at sgj. Southerly surface
winds of 5-10 mph are expected to develop at the regional
terminals shortly after sunrise, with the atlantic sea breeze
boundary crossing sgj towards 16z, resulting in east-southeasterly
surface winds increasing to 10-15 mph. This sea breeze should also
cross ssi and crg by 18z. Scattered to numerous showers and
thunderstorms will impact the regional terminals after 18z Monday.

Marine
Weak low pressure over the florida panhandle will meander
northward over western georgia and eastern alabama through
Tuesday. The axis of atlantic ridging will slowly lift northward
from a position across central florida early this week to the
northeast florida waters by midweek. A loose pressure pattern will
prevail locally, resulting in afternoon sea breezes over the near
shore coastal waters and south-southwesterly evening wind surges
that will build seas offshore to 3-4 feet each night. Seas of 2-3
feet will otherwise prevail over our waters this week. A frontal
boundary will then move into the southeastern states from the
north late this week and is expected to stall just north of the
georgia waters by next weekend.

Rip currents: low risk expected at area beaches on Monday. Low-end
moderate risk possible by Tuesday and Wednesday during the
afternoon hours as a longer period east-southeasterly ocean swell
develops and combines with the sea breeze and the outgoing tide
during the afternoon hours.
