.KEY MESSAGES...

- Showers and thunderstorms are possible across much of the area
  each day over the next seven days. Widespread severe weather is
  not expected at this time, but rainfall may improve drought
  conditions in some areas.

- Temperatures will remain within a few degrees of seasonal norms
  through midweek next week.

.SHORT TERM...
(Today through Sunday)
Issued at 234 AM EDT Sat Apr 25 2026

Ahead of an advancing cold front, showers and embedded thunderstorms
have begun to overspread portions of north and west Georgia. The
initial push of light precipitation this morning has developed on
the fringes of a decaying MCS that pushed southeastward across MS
and into AL over the past several hours. An MCV churning across
central Alabama (leftover from the aforementioned MCS) will bear
watching through the remainder of the morning and into the
afternoon, as it could serve to focus and weakly organize convection
within its vicinity. As it stands, instability remains anemic and
hodographs are unimpressive, so a realistic "ceiling" through
daybreak is a few rumbles of thunder and errant lightning strikes.

HiRes guidance suggests a relative lull in any convective activity
through late morning before coverage begins to increase again this
afternoon. A caveat here is that CAMS have struggled with capturing
ongoing convection to our west at initialization over the past
several hours -- even now, the light returns across portions of
north Georgia are not well-modeled -- so there remains some
uncertainty as we move throughout the day. That being said, moisture
has rebounded over the past 24 hours (observed dewpoints in the 50s
to lower 60s vs. 40s to lower 50s this time yesterday), so even
modest instability this afternoon will support the development of
scattered to potentially numerous thunderstorms.

After peaking in coverage late afternoon/early evening, any
lingering showers and thunderstorms should continue to taper off
through midnight. Rainfall totals will be meager, generally on the
order of a quarter of a half of an inch. Isolated amounts up to an
inch are possible in thunderstorms. Not a drought buster by any
means, but welcomed all the same.

Moving into Sunday, much of north and central Georgia are progged to
be post-frontal around sunrise, with a brief push of weakly drier
air moving in aloft. Given less stark airmass changes, 15-30%
chances for showers and thunderstorms will be maintained across
southern and eastern portions of the area into the afternoon,
supported by lingering frontal forcing and lift generated by a
passing disturbance at the mid-levels. Even so, most will likely
remain dry to round off the weekend.

Highs today will be several degrees cooler (relatively speaking) for
areas along and north of I-85, in the 70s to near 80. Further south,
yet another day in the 80s -- and potentially 90 for our far
southeastern tier. Little post-frontal effects will be felt on
Sunday, with morning lows in the mid-50s to lower 60s, and afternoon
highs back into the 80s areawide.

.LONG TERM...
(Sunday night through Friday)
Issued at 234 AM EDT Sat Apr 25 2026

The progressive upper level flow pattern will continue early next
week as the axis of a ridge over the eastern CONUS clears Georgia to
the east. With surface high pressure under the ridge moves over the
Northeast, a CAD wedge will develop on the lee side of the
Appalachians and spread into northeast Georgia. Some uncertainty
remains with respect to the strength and duration of this wedge.
Under this wedge, temperatures are forecast to be limited to the mid
to upper 70s (and even upper 60s at the ridgetops) compared to low
to mid 80s in central Georgia. The cooler, more stable airmass
within this wedge will inhibit convection through the majority of
the day, with PoPs of 10% or less across the area. Meanwhile, the
next system to impact our area will be brewing across the central
CONUS. As strong troughing rotates around a closed low over
south- central Canada, cyclogenesis will occur over the Midwest,
aided by a strong subtropical jet. The surface low will quickly
intensifies and extend a cold front into the Lower Mississippi
River Valley. Isolated showers and thunderstorms may begin to work
their way into far northwest Georgia by on Monday night as the
warm sector ahead of the front begins to spread further east.

More widespread showers and thunderstorms are forecast to return
after midnight and into Tuesday morning. With a warm and moist
environment becoming more established ahead of the front and
potentially robust low-level shear profiles where the wedge boundary
lingers, there is a conditional threat for a few strong to severe
thunderstorms. The chance for severe weather will depend on the
position of the wedge boundary and whether or not there will be
sufficient surface-based instability as the front begins to work its
way into the area during the overnight hours. Where conditions
align, strong to severe thunderstorms that occur would be capable of
producing damaging wind gusts, and a brief tornado cannot be ruled
out (most likely along said wedge boundary). Low level shear is
progged to be weaker during the daytime, but increasing instability
will keep thunderstorm activity and a risk for at least an isolated
stronger thunderstorm going into the early afternoon. Shower and
thunderstorm coverage will become more isolated as the frontal
forcing weakens as it pushes further into the state.

More numerous showers and thunderstorms will return on Wednesday as
a shortwave disturbance moves eastward from the Lower Mississippi
River Valley. This second wave will overrun the tail end of the
frontal boundary lingering from Tuesday. The disturbance and front
will gradually advance southward, clearing the forecast area to
the southeast by Thursday morning. 7 Day rainfall amounts are
forecast to be between 1.5-2.25" north of I-85, with progressively
diminishing amounts to the south and east, down to about 0.5" in
east-central Georgia. Locally higher totals will be possible where
stronger storms occur. Increasing surface pressure and drier air
will set up over the Southeast on Thursday into Friday.

.AVIATION...
(18Z TAFS)
Issued at 142 PM EDT Sat Apr 25 2026

Mostly VFR with patchy MVFR/IFR at the northern sites in
association with heavier -shra to start. Coverage in -shra and iso
-tsra will increase slightly after 19z with the best window still
 looking to be until 02z mainly at the northern terminals. Pcpn
 will start to come to an end by then with SCT-BKN 5-15kft cigs
 thereafter. Low cigs (MVFR to IFR) will be possible as early as
 07-08z lasting thru 14z. Patchy LIFR will also be possible mainly
 between 10-13z. This will be accompanied by MVFR vsbys in BR. SW
 winds will shift to the NW after 02z.

//ATL Confidence...18Z Update...

Medium confidence.
