.SHORT TERM...
(Today through Friday)
Issued at 342 AM EDT Thu Jul 11 2024

Key Messages:

  - Forecast remains dry for most of Thursday and Friday, with the
    exception of east central GA late Friday afternoon/evening.

  - Will get progressively warmer today and tomorrow, though
    dewpoints remain reasonable for this time of year. This should
    prevent the need for any heat product issuance.

Forecast:

A lovely start to the day with minimal cloud cover in most of north
and central Georgia and temperatures in the mid to upper 60s in the
north and low 70s in central Georgia. Not quite Fall levels of
crisp, but we`ll take it in the middle of July. Beautiful day
expected in our post frontal airmass. High temps will be in the low
to mid 90s (save for the mountains), but humidity remains relatively
low, keeping our "feels like" temperatures reasonable. No precip
expected. Tonight, temps won`t be quite as cool, but will still be
into the 60s and low 70s with mostly clear skies.

Friday looks like more of the same as not much in the way of any
synoptic system looks to come along and kickstart any kind of
meaningful moisture return. Temperatures will be even warmer in many
locations, reaching into the mid to upper 90s by the afternoon, but
it remains relatively dry. Some moisture return may begin by later
Friday evening as strong Bermuda high slides a bit to the southwest,
promoting onshore flow off the Atlantic. This will bring back some
later afternoon/early evening rain chances across east central
Georgia.

.LONG TERM...
(Friday night through Wednesday)
Issued at 342 AM EDT Thu Jul 11 2024

The Southeast will remain wedged in between the stout upper ridge
anchored across the Intermountain West and the Atlantic Ridge to
our east to start the extended period. With deeper moisture
remaining shunted to our south and east near and south of a
lingering stationary boundary, a drier airmass will remain
entrenched across the forecast area through the weekend. PoPs will
thus remain primarily of the isolated variety through Sunday, though
slightly higher coverage (low end chance) will creep begin to back
into the southeast zones. High temperatures will climb into the mid
to upper 90s each afternoon, though (relatively) lower afternoon
dewpoints in the 60s should keep afternoon heat index values below
Heat Advisory criteria of 105.

The aforementioned ridging across the West will begin to encroach
farther eastward by the early work week, keeping temperatures above
average. PoPs look to remain of the isolated to widely scattered
diurnal variety through Tuesday within the continued weakly forced
environment. With dewpoints slowly creeping upward by Tuesday, more
humid, uncomfortable conditions will make a gradual return. By the
tail end of the long term on Wednesday, a cold front looks to make
progress toward the forecast area. As such, above-climo PoPs should
make a return in the presence deeper moisture return in advance of
the front.
