.UPDATE...
Issued at 125 AM EDT MON SEP 15 2025
No significant changes were made to the forecast with mainly just
the inclusion of the latest obs and trends for the T/Td/Sky grids.
These minor adjustments have been sent to the NDFD and web
servers along with a freshening of the zones and SAFs.
UPDATE Issued at 1101 PM EDT SUN SEP 14 2025
Raised ridgetop temperatures a few degrees, otherwise forecast is
still on track. Expect mostly clear skies, except for fog in the
favored mainstem river valley locates, and low temperatures in the
mid 50s to low 60s.
UPDATE Issued at 748 PM EDT SUN SEP 14 2025
Forecast through the overnight remains on track. Given relatively
good agreement among recent high-res model solutions for weak
upper level energy coincident with increasing low-level moisture,
have added a slight shower chance to far southeastern Kentucky on
Monday afternoon.

.SHORT TERM...(This evening through Monday night)
Issued at 252 PM EDT SUN SEP 14 2025
North-northeasterly flow aloft will become increasingly more
cyclonic in nature as a large double-barreled stacked low
strengthens and grows in size over the Carolinas and southern
Virginia. This feature then meanders in place as a surface low
strengthens and moves toward the North Carolina coastline.
Meanwhile, a narrow mid-levelhigh ridge continues, extending from
Texas northeast to the Great Lakes.
Our tranquil and warm weather pattern will continue through the
short-term period, with mostly clear skies through tonight gradually
giving way to increasing high clouds from the east through Monday
night on the periphery of the low. The main impact will be slightly
cooler daytime temperatures and less ridge-valley splits in
overnight low temperatures, and this will moreso be the case in the
far eastern parts of the forecast area.
.LONG TERM...(Tuesday through Sunday)
Issued at 340 PM EDT SUN SEP 14 2025
The upstream positively-tilted shortwave trough that clips through
the Northern Plains early this week will lift into Ontario and
Quebec slowly through the week, strengthening as it is absorbed into
the parent longwave trough at the end of the week. Ahead of the
trough, a ridge sits over the Great Lakes area. Meanwhile, another
closed upper low off the Carolina coast will retrograde back to
the shoreline before pushing north through the Northeast. Global
ensembles are in good agreement about the progression of this
synoptic pattern through midweek.
Tuesday and Wednesday will have high temperatures in the low to mid
80s at elevations below 2kft, with temperatures staying cooler in
the Cumberland Mountains in the 70s or even as low as upper 60s.
Overnight lows will drop to mid 50s. Northeasterly flow along the
western periphery of the east coast low will advect moisture into
the area through Wednesday, increasing cloud cover and bringing
dew points into the 60s. PoPs remain below 10% Tuesday and
Wednesday, though patchy ground fog will be possible in the
valleys.
Confidence is high that the wave along the eastern seaboard will
move northward in time for ridging to build in its wake Thursday,
with warm air advection increasing temperatures into the upper
80s on Thursday and Friday. PoPs
