.SHORT TERM...
(Today through Sunday)
Issued at 336 AM EDT Sat May 2 2026

The short term starts off with a developing closed low center
across south GA moving east with Showers across the state. This
low center will push off the GA coast around sunrise and move up
the eastern seaboard through this evening. This low center will
pull the frontal boundary and its associated showers offshore as
well allowing a drier airmass to move into the region through
Sunday. The showers will be ending from NW to SE across the state
today with clearing conditions expected this afternoon/evening as
high pressure begins to build into the area from the West. Some
locations across central GA will see an additional 0.5" to 1" of
rain before the precipitation comes to an end. Most locations
across North GA will be lucky to see 0.1" to 0.5" today. Things
clear out Sunday and continue to stay clear into the extended
periods.

This boundary exiting the area will not only end our precip
chances but it also ushers in a slightly cooler airmass with
temps today expected in the 60s to near 70. Low temps tonight will
dip down into the 40s with some upper 30s in the NE GA mountains.
Temps Sunday will still be slightly below normal for this time of
year but will begin to rebound with highs in the lower to middle
70s.

.LONG TERM...
(Sunday night through Friday)
Issued at 336 AM EDT Sat May 2 2026

The long term picks up with expansive surface high pressure situated
across the Southeast, bringing below normal temperatures Monday
morning. While not as chilly as the previous night, lows in the 40s
are expected areawide. A warming trend will begin on Monday as high
pressure shifts east and midlevel flow becomes more zonal and
transitions into broad ridging. High temperatures will thus rebound
back to near normal (upper 70s to mid 80s).

The next chance for precipitation arrives by mid-to-late week,
likely somewhere in the late Wednesday into Thursday time frame,
though timing continues to remain uncertain at this juncture. We`ll
need to monitor thunderstorm potential with this next
trough/associated surface front, though current timing uncertainties
also fold into uncertainties regarding warm sector quality, etc.
Behind this system, another cooldown is likely by late week as high
pressure brings a return to drier weather.
