.SHORT TERM...
(Today through Tuesday)
Issued at 353 AM EDT Mon Apr 14 2025

Key messages:

 - Warmer temperatures today.

 - Light showers across the N tonight.

 - Cooler temperatures on Tuesday.

Mostly sunny skies are expected again today, although clouds will
begin to filter into NW GA late in the afternoon. Temperatures will
continue to warm, with highs ranging from the mid 70s in the NE
mountains to the lower to mid 80s elsewhere. These temperatures will
be around 10 degrees above normal in N GA and about 5 to 7 degrees
above normal across central GA. SW winds will pick up a bit, with
gusts over 20 mph in N GA during the afternoon.

A weak cold front will approach the area from the NW this evening,
with isolated to low end scattered showers moving into the County
Warning Area (CWA) before weakening. Rainfall amounts are expected to
average less than a tenth of an inch N of the Atlanta metro area.
Some trace amounts are possible a bit farther S. MUCAPE (instability)
will be very low (mostly less than 100 J/kg). Additionally, there
will be CIN in place, and daytime heating will be gone by the time
showers move in. As a result, although the chance of thunder is non-
zero, it`s not enough to mention in the forecast.

The biggest impact of the cold front will be to knock temperatures
back down to near or slightly below normal. After lows tonight mostly
in the 50s, daytime highs on Tuesday will range from the upper 50s in
the NE to near 80 in the extreme SE.

Minimum relative humidity values will range from 22 to 30 percent
this afternoon, with the lowest values generally SE of Macon. Fuels
will be dry, so humidities will need to be monitored for a possible
short fuse Fire Danger Statement. However, duration and areal
coverage of sub-criteria humidity precludes issuance at this time.

Breezy NW winds are expected Tuesday, with gusts of 20 to 30 mph.
Wind gusts near 35 mph will be possible in the higher elevations in
N GA. Minimum relative humidity values are forecast to drop below 25
percent across most of the area, and fire wx products will likely be
required. /SEC

.LONG TERM...
(Tuesday night through Sunday)
Issued at 353 AM EDT Mon Apr 14 2025

Key messages:

 - Warm and mostly dry through the weekend.

Surface high pressure and northwest flow will return and dominate
the weather pattern Tuesday Night through the end of the week. A
midlevel ridge situated over the Central CONUS, will begin shifting
eastward becoming more amplified as a low develops and deepens over
the western CONUS by the weekend. Additionally, the surface high
center will move off the East Coast. Latest ensembles continue to
remain on the drier side with this next system though there is still
some variation in timing/strength of it. Though as it stands, any
notable rain chances look to hold off until next week. Thus, warm and
dry conditions will prevail across North and Central Georgia through
Sunday. Fire weather conditions will likely need to be monitored
across the forecast area through the end of the work week given
continued warm and dry conditions. Temperatures also trend warmer
through the end of the period as ridging becomes amplified over the
southeast through the week. Forecast highs start off in the low 60s
to mid 70s (Wednesday) climbing into the mid to upper 80s -- flirting
with low 90s in Central GA -- by Friday and through the weekend.

Mostly VFR conditions will continue through the period. Cirrus
clouds will be mostly SCT for the next few hours. Light to calm winds
will increase out of the SW during the mid-morning hours with
occasional gusts over 20 kts into the afternoon. Some multi- layered
clouds will make it to ATL by the end of the forecast period ahead of
an approaching weak cold front. Showers are expected to mostly stay
N of the Atlanta metro area, but have included a VCSH late at ATL.

//ATL Confidence...12Z Update...
Medium for late night shower chance, high for other elements.
