Area Forecast Discussion
National Weather Service Columbia SC
116 AM EST Sat Jan 2 2021

.SYNOPSIS...
A frontal boundary will remain nearly stationary across the
central Midlands with wedge conditions slowly eroding overnight.
A strong cold front will move through the region tonight.
Showers will continue ahead of the front this evening. The
front will stall near the coastal plain Saturday and Saturday
night, while a wave of low pressure develops along it, bringing
periods of heavy rain to the area. High pressure will build over
the region late in the weekend into the middle of next week,
resulting in dry conditions.

&&

.NEAR TERM /UNTIL 7 AM THIS MORNING/...
Frontal boundary remains nearly stationary across the southern
Midlands early this morning.

Low pressure centered across Kentucky with cold front south
through Tennessee into Alabama. The front will move into the
area late tonight and stall out. Not sure it will push through
the Midlands and east central Georgia. This may be the focus for
heavy rain tomorrow.

Radar indicating line of showers, mainly across eastern portions
of the forecast area. The showers will continue to slowly push
east while diminishing in coverage.

&&

.SHORT TERM /7 AM THIS MORNING THROUGH SUNDAY NIGHT/...
Flash Flood watch for Saturday evening through the overnight
period as heavy rain will be possible...

Upper low over the southern Plains will move northeast across
the Mississippi Valley Saturday afternoon. Strong southwest flow
aloft across the area with deep moisture spreading into the
Southeastern States as seen by water vapor already. 140kt upper
jet over Tennessee Valley Saturday night. Favorable entrance
region from this jet across region resulting in strong upper
divergence across SC/northeast Ga. Precipitable water greater
than 250 percent of normal. Low pressure expected to move
northeast along stalled frontal boundary enhancing rain during
the late evening.

Rain, heavy at times, will begin again late Saturday afternoon
and continue into Saturday night. Rainfall amounts generally in
the 1-2 inch range expected. Higher amounts not out of the
question given training of showers and isolated thunderstorms.
Will issue a Flash Flood Watch for the CWA from late Saturday
afternoon into early Sunday morning. The front will move off the
coast by Sunday morning with rain ending from west to east.

Fair weather will return Sunday as deep dry air moves in behind the
the storm system. Temperatures will be seasonably warm with highs in
the upper 50s to lower 60s. Lows Sunday night will be in the
30s.

&&

.LONG TERM /MONDAY THROUGH FRIDAY/...
Dry weather is expected through the middle of next week
as a deep layered ridge sets up over eastern North America. The
air mass will be of pacific origin, so temps will be seasonable
through Wednesday. Another strong system looks to work its way
across the southern US and will increase our chances for rain
Thursday into Friday.

&&

.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
A stalled front over the area has KCAE/KCUB on the cool/stable
side, while KOGB/KAGS/KDNL reside on the warm and more unstable
side. The Columbia area terminals likely have IFR ceilings
deteriorate to LIFR levels early this morning, while the other
terminals deteriorate from MVFR to IFR ceilings. While some
reduced visibilities are possible at all terminals, the most
significant visibility reductions should occur at KCAE/KCUB
through mid-morning. Some improvement to MVFR is expected this
afternoon, but showers will overspread the terminals late this
afternoon and this evening, brining additional restrictions.

Low level wind shear could be an issue at the SC terminals
through about 9Z, then the jet should shift away from the area.
Surface winds will generally be 10 kt or less.

EXTENDED AVIATION OUTLOOK... Another low pressure system
expected to continue MVFR/IFR restrictions with periods of rain
Saturday night into Sunday morning. Dry and VFR conditions
Monday through Wednesday.

&&

.HYDROLOGY...
Periods of moderate to heavy rain expected through Sunday
morning, with heaviest rainfall forecast Saturday evening as
another low pressure system transits the forecast area. With up
to 2 inches of rainfall already in basins tonight, The additional
rainfall may produce areal and flash flooding beginning Saturday
evening.

Minor to possibly moderate flooding is forecast along portions
of the Congaree River, with the Wateree, Pee Dee and Edisto
Rivers reaching action stage. All other area rivers and streams
will be running at higher than normal levels through mid-week.
See river flood advisory and warning products for specific
details.
