...Afternoon Area Forecast Discussion...

.SHORT TERM...
(This evening through Tuesday)
Issued at 343 PM EDT Mon Jun 12 2023

An active pattern is expected in the short term period, with the
Southeast CONUS situated between a persistent upper ridge over the
northwestern Gulf of Mexico and a closed low centered over the
northern Great Lakes region. A tight gradient between these two
features is contributing to compressed zonal flow aloft. A surface
low associated with the upper closed low is extending a cold front
through the region, which is currently bisecting the forecast area,
and is expected to continue moving southeastward through the
remainder of the afternoon and into the evening. Cooler
northwesterly winds behind the front combined with a persistent low
cloud deck will keep afternoon temperatures across north Georgia
limited to the upper 70s and low 80s. However, to the south of the
front, cloud coverage has been more scattered, allowing for more
diurnal heating and temperatures rising into the upper 80s to low
90s. With convergence ahead of the front and MUCAPE increasing to
between 2500-3500 J/kg in central Georgia, scattered thunderstorms
have begun to quickly develop ahead of the cold front over the last
couple of hours. These storms are expected to persist into the early
evening hours, at which point they will weaken and move out of the
area as the cold front approaches our southern border. With modest
low-level shear of 15-20 kts ahead of the frontal boundary, combined
with low-level lapse rates between 7-8 C/km and DCAPE values between
700-900 J/kg, there is the potential that a few storms could become
strong to severe, capable of producing damaging wind gusts and large
hail.

Tonight, the aforementioned ridge will move eastward and the low
pressure system over the Great Lakes region will begin to occlude,
setting Georgia up underneath strong zonal flow aloft. At this
point, the cold front will become oriented nearly parallel to this
zonal flow and stall across south-central Georgia. Much of north
Georgia will remain within the post-frontal airmass tonight into
Tuesday. Low temperatures on Tuesday morning are expected to be in
the mid 50s to low 60s to the north of the front and mid to upper
60s south of the front. Dewpoints will gradually increase through
the day on Tuesday as low-level winds shift from northwesterly to
southwesterly, increasing into the 60s across the area (and even
some low 70s in south-central Georgia) by Tuesday afternoon.
Precipitable water values will similarly recover to between 1.5 to
1.75 ". Afternoon highs on Tuesday are expected to be mainly in the
upper 70s in north Georgia and 80s elsewhere across the forecast
area.

A feature to keep an eye on Tuesday will be a mid/upper level
shortwave quickly traversing the nearly zonal flow from the southern
Great Plains towards Georgia. Continued moisture transport will also
be ongoing within the mid to upper level flow and southwesterly
surface flow. As a result, showers and thunderstorms will increase
in coverage from west to east tomorrow morning and into the
afternoon, with highest chances near the stalled frontal boundary
across the southern tier of counties. With warm air advection
ongoing, portions of central Georgia could see MUCAPE values
increase to between 2000-3000 J/kg during peak heating hours
tomorrow afternoon. With deep layer bulk shear values furthermore
between 40-50 kts, there is the possibility that some storms could
become severe and capable of producing damaging wind gusts and large
hail. However, it should be noted that the severe threat in the peak
heating hours will be contingent upon convection earlier in the day,
and will thus need to be monitored as it evolves.

The frontal boundary will begin to meander back to the north on
Tuesday night into Wednesday morning, at which point another
shortwave disturbance will bring numerous showers and thunderstorms
across the forecast area once again, with highest chances once again
focused along the front. Rainfall amounts on Tuesday through the
start of the day on Wednesday are expected to be between 1-1.5
inches across central Georgia, with progressively lower amounts to
the north, further away from the frontal boundary. Some stronger
storms could produce locally heavy rainfall, which could lead to
isolated flooding concerns. This won't be end of a wet week, though,
as more showers and thunderstorms are expected after the extended
period picks up on Wednesday...

.LONG TERM...
(Wednesday morning through next Sunday)
Issued at 343 PM EDT Mon Jun 12 2023

It's shaping up to be a fairly active week across North and Central
Georgia in the long term. Synoptically, our forecast area will be
sandwiched between a developing upper low across the Great Lakes
and broad ridging across the western Gulf resulting in quasi-zonal
like flow aloft for the first part of the extended forecast. At
the surface, a frontal boundary is forecast to still be making its
way northward across the area by Wednesday. A few shortwaves will
pass through the main flow and will aid in more numerous to
widespread storms mainly the in vicinity of where the frontal
boundary sets up Wednesday into Thursday. Dewpoints during this
time will climb into the upper 60s to low 70s with PWATs on the
order of 1.5 to 2.0" making for a juicy airmass and resulting in
instability nearing 2500 J/kg (SBCAPE). The Storm Prediction
Center (SPC) has highlighted much of central and south Georgia in
a marginal to slight risk of severe storms on Wednesday with
strong gusty winds and hail being the main threat. Though given
the recent rainfall we've seen over the past two days, localized
heavy rainfall and flash flooding will be a growing concern this
week by this point in the week. In addition to the severe weather
outlook the Weather Prediction Center (WPC) has highlighted an
area, similar to that of SPC of a marginal to slight risk of
excessive rainfall.

Models start to diverge by the weekend though it looks like by
Friday and through the weekend any convection will be more diurnally
driven as the upper low to our north translates east and flow aloft
weakens. A slight warming trend can be expected as far as
temperatures. Highs are forecast to be in the 80s warming to the
upper 80s/low 90s by the end of the work week. Low temperatures will
generally be in the 60s through the remainder of the week.

The biggest thing to note for the extended forecast going forward is
the fact that this is an evolving forecast and a lot of what will
occur later this week will largely be dependent on what transpires
the previous day (i.e convection on Wednesday will largely be
dependent on how things evolve on Tuesday). Stay tuned...

.AVIATION...
(18Z TAFS)
Issued at 141 PM EDT Mon Jun 12 2023

As the period begins, skies are mainly BKN to OVC across the area
with ceilings ranging from 025-035. Ceilings are expected to lift
to low VFR by 20Z. SHRA/TSRA has begun to develop ahead of the
cold front advancing southward through Georgia. VCSH has been
introduced at the ATL sites and AHN until 19-20Z, at which point
precipitation should move to the south. With better coverage
expected in central Georgia, a TEMPO for TSRA has been introduced
from 18-22Z at MCN. SHRA/TSRA will diminish after sunset. Winds
will be W to NW through the period, at 10-12 kts with gusts up to
22 kts this afternoon, diminishing to 4-8 kts overnight. SHRA/TSRA
will spread from west to east into Georgia late tomorrow morning
into the afternoon.

//ATL Confidence...18Z Update...
Medium confidence on timing of precipitation.
High confidence on all other elements.
