...New 18Z Aviation Discussion...

.SHORT TERM...
(Today through Wednesday)
Issued at 331 AM EDT Tue Jun 11 2024

Old frontal boundary is currently across far south GA/north FL. This
boundary will remain nearly stationary, but could wave just a little
northward tomorrow afternoon. The forecast will remain dry today,
but some isolated pops are possible in the far south CWA
tomorrow...nearest to the old boundary.

Temps will remain seasonable. Dewpoints will be very pleasant today
and average in the lower to middle 50s. Low level moisture will
begin to increase slightly tomorrow and dewpoints will creep upwards
into upper 50s to middle 60s.

(Wednesday night through Monday)

Not much change from previous discussion. Models continue to have
trouble locking in on the evolution of the Gulf low, though models
continue to develop the low anyways. Moisture within the low will be
high (PWATs 2.5+"). The question is where the low will go. As of
now, models have shifted eastward with a stronger Bermuda high in
the Atlantic. This drives the moisture more into the Mississippi
Delta region, however this is likely to change. PWATs over GA also
look to be difficult to forecast. This is due to the easterly flow
from the Bermuda high, which has the potential to keep PWATs as low
as 1". Given the large spread in potential PWATs, will maintain at
least some PoPs across the southern CWA for much of the extended
outlook and particularly in the afternoon. Further discussion on
thunderstorms can be seen in previous AFDs, but in short expect
showers and thunderstorms possible everyday in the southern CWA
and this possibly spreading to include North GA in later forecast
iterations.

Temperatures will be HOT. Expect the hottest conditions so far this
year with a general increase in highs through Saturday before we
cool off a little bit. Highs by the weekend will be in the mid to
upper 90s across the entire CWA. Dewpoints in the upper 60s and
lower 70s will mean that heat could be a threat, particularly to the
most vulnerable populations (elderly, pets, etc.).

.AVIATION...
(18Z TAFS)
Issued at 128 PM EDT Tue Jun 11 2024

Wind shift to the east still expected overnight tonight.
Winds could go calm before transitioning over to the east side
near daybreak but will keep the 05z shift in the ATL for now
as it appears to be a pivot point from N to NNE.  Winds overall
will be very light after sunset today...5kts or less at all sites.
Moisture increases at 250 after 06z per cross sections and at 010
late AM on Wednesday. Expect mid and high cloud cover to impact
all taf sites during the day tomorrow.

//ATL Confidence...18Z Update...
High confidence all elements
