...Afternoon Area Forecast Discussion...

.SHORT TERM...
(This afternoon through Saturday)
Issued at 214 PM EDT Fri Apr 18 2025

Key Messages

    -Temperatures will remain well above normal through the short
     term, nearing daily record highs on Saturday.

    -No rainfall is expected through Saturday night.

Warm and dry conditions will persist through Saturday night courtesy
of surface high pressure centered over the western Atlantic and
midlevel ridging over the Southeast. With the ridge building further
and reaching its zenith on Saturday, highs will reach the mid to
upper 80s areawide - well above normal for mid April. Records for
the date range from 88 for Atlanta, 91 at Athens and Macon, and 93
at Macon. Current forecast highs fall just shy of the records,
though Atlanta will be closest (currently one degree shy) and thus
has the highest probability of potentially reaching the record for
the date.

Otherwise, southerly flow will promote gradually increasing
dewpoints through Saturday and should prevent any fire danger
concerns as we head into the weekend.

.LONG TERM...
(Sunday morning through next Thursday)
Issued at 214 PM EDT Fri Apr 18 2025

Key Messages:
- Above average temperatures through the longterm. Highs in the 80s.

- Low end PoPs starting Monday and continuing each day through the
end of the week.

Building upper level ridge and increasing southerly flow will mean
highs in the mid 80s Sunday and likely remain above 80 through next
week. Subsequently, lows will be in the 50s and 60s. Current NBM
guidance has run warm compared to many models, suggesting that
highs in the mid term could be slightly over done.

Not likely to see much in the way of appreciable rainfall through
the long term. The greatest chance for any rain/thunderstorms will
come with a stalling cold front sometime Monday, mainly across North
GA. Current deterministic models indicate arrival time Monday
morning, however given the stalling and uncertainty in how much the
mid/upper level ridge may break down, the front may move slower than
anticipated. QPF with the monday system will remain below 1". Though
CAPE values will be around 1000J/Kg, with the supportive dynamics
well to the north, no severe is expected at this time.

A modest chance for showers and thunderstorms remains through the
rest of the week. Diurnal heating will relegate formation mostly to
the afternoon hours and forcing will be best along the stalled front
(wherever that may be).
