Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
712 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 710 PM EDT Wednesday: The cold front has moved south of I-85
this evening with a wind shift and showers for the eastern Upstate.
Showers should end and clouds diminish through the evening as the
front moves south of the area. Winds will diminish as well. Expect
some mountain valley fog before daybreak. 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 /23Z WEDNESDAY THROUGH MONDAY/...
At KCLT and elsewhere: VFR conditions at all terminals through the
TAF period. Showers along a cold front have moved south of KCLT and
east of KGSP and are not expected to cross any TAF sites. Winds have
shifted behind the front for all but KAND where that should occur
around 02Z. Expect N to NE wind, with lighter speeds overnight. VFR
stratocu will scatter and dissipate as well. Expect mountain valley
fog, but not at KAVL. N to NE winds pick back up with mixing
Thursday morning, then shift to the S to SE as the center of high
pressure moves off shore. High clouds will increase late in the
afternoon.

Outlook: Rain and associated restrictions develop Friday as a warm
front lifts north across the area. Clouds linger Saturday, along
with the potential for isolated mountain convection which lingers
into Monday.
