Area Forecast Discussion
National Weather Service Columbia SC
641 PM EDT WED JUL 20 2016

.SYNOPSIS...
An upper-level trough over the East Coast will shift farther east
tonight as surface trough remains over the region through
Thursday.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
Surface trough extending from the upstate southeast across the
Midlands to the north Coast this afternoon. Instability remains
moderate with LI around -5 and around 2000 J/kg.  Showers and
thunderstorms have been isolated due to drier air across the
region today. High resolution models suggest convection in the
Upstate may track southeast later this evening. Will continue
to monitor radar trends but will keep current slight chance pops
after sunset with lack of strong short wave trough. Temperatures
overnight will again be in the lower to middle 70s.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/...
An upper trough along the East Coast will push further east on
Thursday as a massive upper ridge expands over the center of the
country. The diffuse frontal boundary will be south of the region
Thursday with high pressure ridging into the area at the surface.
High pressure will shift slightly east on Friday as lee-side
troughing develops. The deepest moisture will be in the southern
portion of the area for Thursday so have continued to indicate
chance pops in the CSRA and southeastern Midlands and slight
chance further north. Precipitable water values across the area on
Friday are forecast to drop below 1.5 inches, which is normal for
late July. This in addition to subsidence from the ridge should
limit convective activity so have maintained only slight chance
pops. Lower to middle 90s expected for Thursday and slightly
warmer temperatures on Friday as the ridge expands east over the
area.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
The main forecasting concern in the long term is the heat over the
weekend. An upper ridge over the center of the country will build
eastward while a lee trough sits over the area at the surface.
This pattern will promote temperatures in/near the triple digits
Saturday and Sunday. Peak heat indices are generally expected to
be around 105 to 109 on Saturday and closer to 110 on Sunday. A
heat advisory may be needed as we head into the weekend. Moisture
will increase Saturday and Sunday with precipitable water values
returning to near 1.9 inches. Strong heating combined with
convergence into the trough and moderate instability will promote
diurnal convection, although the upper ridge may cap convection.
The upper ridge will begin to weaken early next week which should
lead to increased thunderstorm chances and slightly cooler
temperatures.

&&

.AVIATION /00Z THURSDAY THROUGH MONDAY/...
Mainly VFR conditions through the TAF period.

Isolated thunderstorms this afternoon will diminish after sunset.
At 22z...convection not expected to impact Terminals. Scattered
cumulus and high mid level clouds. With dry air aloft and low
level moisture high there is potential for some early morning fog
Thursday. There is fog support from lamp...But confidence not high
however. Plan on tempo MVFR fog toward daybreak.

EXTENDED AVIATION OUTLOOK...Restrictions possible in
afternoon and evening convection Wednesday and Thursday...with
lower chances Friday through Sunday. Potential for early morning
fog/stratus...mainly AGS/OGB.

&&

.CAE WATCHES/WARNINGS/ADVISORIES...
GA...None.
SC...None.
