Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
209 PM EDT Wed Apr 24 2024

.SYNOPSIS...
A weak cold front should stall to our south tonight and Thursday as
high pressure moves past to our north. The front will move back
northward on Friday and wash out across our area, but giving us a
cooler day because of clouds and a few showers. After that, expect a
warming trend through the weekend and into next week as high
pressure takes over.

&&

.NEAR TERM /THROUGH THURSDAY/...
As of 148 PM EDT Wednesday: A shortwave trough over the Mid-Atlantic
will continue to lift offshore this afternoon. In its wake, a tall
upper ridge will build across the Mississippi Valley as the synoptic
pattern becomes amplified with a digging trough over the Desert
Southwest. At the surface, a weak frontal boundary is currently
making its way across the area with the front analyzed along a line
extending from Clayton to Shelby to Monroe. A few isolated showers
were noted on local radars, mainly across the North Carolina
Piedmont, but a dearth of forcing and a prominent dry sub-cloud
layer will continue to preclude greater coverage. Otherwise, a band
of broken mid- and high-level clouds will cross the area with skies
clearing overnight. Low temperatures will be similar to this morning
with low 40s to low 50s. Slightly cooler low-level temperatures
advect in by Thursday, but mostly sunny skies and at least some
degree of downsloping flow should allow for a nice day with highs in
the low to upper 70s.

&&

.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/...
As of 125 PM Wednesday: Mid level ridging will build across the
region through the short range period, as surface high pressure
centered over the Northeast will extend south to the east of the
Appalachians. Low pressure will lift northward across the Plains.

Weak warm advection from the Plains system will combine with
easterly low level flow associated with the surface high to create
plenty of clouds Thursday night through Friday night. A few showers
are possible through these periods, but amounts will be very light.
Plenty of clouds will linger into Saturday, but there should be more
breaks in the clouds and less shower activity.

Due to the clouds and easterly flow, highs will be below climo on
Friday, then climbing back to near climo on Saturday.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
As of 135 PM Wednesday: The mid level ridging will remain in place
for Sunday and Monday leading to increasing sunshine and
temperatures warming above climo. A trof in the mid level flow will
break down the ridge by Tuesday and bring the chance of showers and
thunderstorms to the area. Overall, a quiet period is expected.

&&

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
At KCLT and elsewhere: VFR conditions will prevail at all terminals
through the TAF period. A weak cold front is currently pushing
across the area from the northwest with an associated band of broken
high clouds and a few isolated to widely scattered showers. A stray
shower will be possible in the vicinity of KCLT over the next
several hours, but most locations will stay dry with no impacts.
Skies will gradually clear through the evening with clear conditions
returning by Thursday morning. Winds will shift to out of the
northwest behind the front, but will be weak.

Outlook: Dry weather returns Thursday into this weekend, but this
is subject to change as a warm front lifts north of the area by
Saturday with possible restrictions.
