.KEY MESSAGES...

  - A slightly lower coverage of scattered showers and
    thunderstorms is expected today before rain chances again ramp
    up Friday and Saturday.

  - Locally heavy rainfall will remain the primary concern in any
    thunderstorms given the continued moist environment in place.

.SHORT TERM...
(Today through Friday)
Issued at 310 AM EDT Thu May 28 2026

Today is expected to bring an overall lower coverage of showers
and thunderstorms compared to the next few days. Our persistent
west Atlantic ridge finally has been squashed southward as a
trough drops across the Northeast amid an omega block setting up
across the continental US. Thus, the deep southwest flow that had
been so persistent lately has transitioned into a more west to
northwest flow pattern today, leading to reduced overall
convective coverage. Still, at least isolated to scattered diurnal
convection can be anticipated.

Meanwhile, the aforementioned New England trough will nudge a
surface front southwestward into the Carolinas today, reaching
our area tonight. The front will then stall and roughly bisect the
area from northwest to southeast on Friday. This will lead to a
resurgence in convective coverage on Friday, maximized across the
southwest half of the CWA, while the slightly drier airmass in
northeast Georgia will lead to relatively lower chances the
farther northeast you go. Locally heavy rainfall will remain a
possibility given PWATs will still run at or over 2" as moisture
pools near the front.

.LONG TERM...
(Friday night through Wednesday)
Issued at 310 AM EDT Thu May 28 2026

Not seeing much in the way of long term changes over the coming
forecast period.  Showers and thunderstorms can be expected over a
large percentage of the CWA every day with PoPs each afternoon
exceeding 50%. The longer this trend holds, the less rain it will
take to cause flash flooding concerns. Training thunderstorms during
the afternoon will continue to pose the biggest threat with rain
rates ranging from 2-3" per hour.

The further out into the long range models you go, the messier
things become. The GFS is indicating that some kind of tropical
system in the gulf might force an atmosphere change at some point
early next week while the EURO is pretty set on holding this pattern
in place through the first week of June. There is some indication
that we may get a few days of decreased coverage towards the middle
of the week, but storms will still be possible.

Temperatures remain pretty consistent with highs in the upper 70s
and 80 and overnight lows in the mid 60s.
