.SHORT TERM...
(This afternoon through Monday)
Issued at 248 PM EDT Sun Oct 6 2024

At a glance:

    - Warmer than average

    - An isolated shower possible along/south of Columbus

A stationary boundary draped across the northern Gulf will allow for
a few showers to continue across our far southern tier this
afternoon, primarily along and south of a line extending from
Columbus to Macon, otherwise yet another dry day on tap. A cold
front will approach and breach Georgia from the northwest tomorrow,
effacing our lingering airmass and nudging the aforementioned
boundary further southward, ushering in cooler and drier air over
the course of the day Monday into Tuesday.

Ahead of the cold front, afternoon highs will be unseasonably warm
by as much as 8-12 degrees, topping out in the mid-to-upper 80s
(aside from northeast Georgia, which will remain in the 70s) today
and tomorrow. Lows in the upper 50s to 60s tonight will begin to
drop Monday night as cooler air filters in north of I-85. As such,
expect lows in the upper-40s to lower-50s north, and in the upper-
50s to 60s south, on Monday night/Tuesday morning.

.LONG TERM...
(Tuesday morning through next Saturday)
Issued at 248 PM EDT Sun Oct 6 2024

Key Messages:

  - Little change in the overall long term forecast. Hurricane
    Milton expected to stay south of the area with little impacts.

  - Seasonable air will filter in by Wednesday with highs in the 70s
    and lows in the 40s and 50s.

Forecast:

Large trough will positioned over the northeast CONUS with attendant
surface low over Hudson Bay by Tuesday morning. Surface front will
have been driven into the area, though Hurricane Milton will be off
the west coast of Florida and surface flow around it may keep some
moist Atlantic air in place across central Georgia on Tuesday,
stunting the southward dive of the front. Milton presents a little
bit of uncertainty in the forecast, as well as the only potential
chance for any rain. If some of the more northward tracks pan out,
there is a chance for some of the rain shield to creep into south
central Georgia. This would not bring meaningful impacts - winds
should remain light and rain amounts low.

Will Milton pushing by and potentially undergoing some aspects of
baroclinic transition, the cold front should fully push through the
CWA allowing cooler air to arrive Wednesday and Thursday. High
pressure will continue to slide over the area through the end of the
week, keeping us clear. Temperatures will be very seasonable into
the weekend, with highs in the 70s and lows in the 40s and 50s CWA-
wide.
