...Afternoon Area Forecast Discussion...

.SHORT TERM...
(This afternoon through Saturday night)
Issued at 230 PM EDT Fri Sep 27 2024

Weather conditions have rapidly improved through the day today.
Flood waters from Helene will gradually recede. River flooding
will continue across much of the area into the weekend. Clouds
will continue to wrap around the remnant circulation of Helene as
she gets absorbed by an upper low over the lower OH Valley. Mostly
light showers will continue to pivot around this large
circulation through the weekend across N GA with mostly dry
weather elsewhere.

Low temperatures tonight and Saturday night will range from the
upper 50s across the NE mountains to the mid 60s across the S.
High temperatures on Saturday will range from the mid 60s in the
NE mountains to the mid 80s across the SE zones. /SEC

.LONG TERM...
(Sunday morning through next Thursday)
Issued at 230 PM EDT Fri Sep 27 2024

An upper level trough will linger over the central Appalachians
through early next week. This will allow a slight chance of
showers to linger over the N GA mountains through Monday. Drier
air wrapping around the trough from the W should help keep the
rest of GA dry Sunday and Monday.

Ensemble guidance shifts the trough east into the Atlantic during
the second half of the workweek. As this occurs, an upper level
ridge should build in over the SE. Forecast confidence is high
that this will result in continued dry weather through the end of
the workweek. The overall strength of the upper level ridge looks
modest and this should keep afternoon high temperatures near
seasonal averages all week. Albright/SEC

.AVIATION...
(18Z TAFS)
Issued at 142 PM EDT Fri Sep 27 2024

What remains of Helene continues to move away. Low cigs will
gradually lift and thin this afternoon and evening. SW winds will
continue to be gusty into the early evening, with sustained speeds
gradually coming down by mid evening and gusts becoming less
frequent. Model guidance indicates some generally light showers may
pivot into the Atlanta metro area and AHN during the day Saturday as
the Helene remnant stalls near the TN/KY border. Some SW gusts near
20 knots will mix back to the surface by mid to late morning
Saturday.

//ATL Confidence...18Z Update...
Medium for Saturday showers and cig timing, high for other elements.
