Area forecast discussion, Feb 14, 6:33 AM EST, 3 hours 18 minutes before
Area Forecast Discussion
National Weather Service Columbia SC
633 AM EST Sun Feb 14 2021

.SYNOPSIS...
Rain and below normal temperatures continue as cold air damming
remains in place through the weekend. A brief warm up on Monday
makes way for more rain as another low pressure moves through
the region Monday night. After some dry weather Tuesday into
early Wednesday, the active pattern returns as another strong
low pressure system moves in from the west later this week.

&&

.NEAR TERM /THROUGH TONIGHT/...
The break in the rain is coming to an end with another round moving
in from the southeast. The rain will continue to spread in through
the morning, entering the northern end of the forecast area after
sunrise. CAMs show some dry spots through the morning, but rain
becomes widespread by the afternoon as the weak low pressure in the
Gulf moves into southern Georgia. PWATs increase to around
1.2-1.4 inches, with highest amounts in the eastern Midlands.
Thus, some moderate to heavy showers possible, mainly in the
afternoon, in addition to the intermittent drizzle. While
instability will be weak, can't rule out a stray thunderstorm in
the easternmost CWA. Another .75 to 1 inch of rain through the
forecast period expected. After sunset, showers will diminish
with gradual upper level drying through the evening as the low
pressure moves east offshore and broadens. Lower levels will
continue to be saturated into Monday morning with the wedge
still hanging on. Highs and lows similar to yesterday with only
a few degrees of warming and cooling; mid and low 40s for highs
and upper 30s and mid 40s for overnight lows.

&&

.SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/...
A brief respite from the rainy pattern is expected on Monday as
the forecast area will be in the wake of the departing system
lifting away from the Mid-Atlantic coast and the next one
developing over the lower Mississippi Valley. The CAD wedge is
expected to remain in place, although due to a generally shallow
moisture layer, not very much precipitation it may weaken a bit
and allow for some movement of temperatures on Monday. Large
spread in the MOS Guidance for highs with temperatures at
Columbia ranging from 49 (MET) to 60 (MAV). Climatologically
speaking, these CAD wedges are hard to break without a strong
southerly flow to erode it, so will again lean towards the
cooler MET guidance given extensive cloud cover and some
possible light showers, especially in the morning hours.

Late Monday afternoon into Monday evening, surface low pressure
will develop and deepen over the lower Mississippi Valley and
lift northeastward along the I-85 corridor Monday night. Strong
moisture transport into the region aided by a 50-60 knot 850mb
low level jet will allow PWATs to peak around 1.5 inches which
is nearly 250 percent of normal. The CAD wedge may break across
the eastern Midlands with increasing southerly flow ahead of an
approaching cold front but it is uncertain if it will break
across the central and western Midlands. There remains a slight
chance of thunderstorms across the region Monday night ahead of
the cold front, although they may be elevated atop the low level
wedge for much of the area, but the eastern Midlands may have a
chance at an isolated strong storm if the wedge breaks there.

The surface low will lift away from the region on Tuesday with
chances of rain diminishing from west to east through the
morning hours as drier air works into the region from the west
behind the cold front. There is not much cold air behind the
front, in fact temperatures on Tuesday are expected to be warmer
than Monday due to the CAD wedge conditions, whereas a breezy
day is expected Tuesday with southwesterly winds which will
support high temps ranging from the mid 50s west to lower to mid
60s east. Some cool advection Tuesday night under mostly clear
skies will yield lows in the lower to mid 30s west and mid to
upper 30s east.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
The active weather pattern we have been in will continue
through the end of the week. Wednesday looks to be a dry day
with generally low atmospheric moisture in place initially but
PWATs will be rising through the afternoon into Wednesday night
as strong southwesterly flow develops. A digging upper trough
over the center of the country will induce surface low pressure
development along the Gulf Coast late Wednesday and the low will
rapidly deepen and begin lifting northeastward Wednesday night
into Thursday. PWATs will rapidly increase across the forecast
area by 12z Thursday to just under 1.5 inches which is very high
for this time of year and chances of rain will increase through
the night becoming categorical.

A surface ridge will also strengthen over New England and the
Mid- Atlantic setting up another potential CAD wedge over the
forecast area. Confidence is limited in how strong this wedge
will be as the strong low pressure system lifts up the spine of
the Appalachians on Thursday with a warm front also shifting
northward which is likely to create a sharp temperature
gradient over the area. As low pressure moves through the
forecast area by Thursday night the cold front will move
through bringing another round of rain to the region but
significant rainfall is not expected at this time, with mainly
a half inch or so rain expected. Instability looks limited at
this time but if the warm front is able to push deeper into the
forecast area, thunderstorms may be possible and this will need
to be monitored with time.

The upper trough will cross the area on Friday with much drier
air arriving from the west and chances of rain will lower
through midday with no rain chances by evening. Upper level flow
will become zonal westerly on Saturday with surface high
pressure building into the region. Temperatures will be near to
above normal Wed-Fri and fall back slightly below normal by
Saturday.

&&

.AVIATION /12Z SUNDAY THROUGH THURSDAY/...

IFR conditions will gradually diminish to LIFR once again this
afternoon as deeper moisture moves into the area.

The wedge of cold air is firmly in place through the TAF period,
with an almost unchanging pattern. Rain will become widespread
later this afternoon, with more moisture moving in from the
southwest as a weak low moves in from the Gulf. Rain will be
moderate to heavy at times, bringing visibilities down to IFR to
LIFR range. Some brief periods of MVFR possible during breaks
in showers. At present, ceilings are mainly IFR, however will
likely lower again late afternoon.

EXTENDED AVIATION OUTLOOK... Moisture and unsettled weather will
continue to cause flight restrictions into Tuesday. Rain returns
Wednesday night into Thursday with some restrictions possible.
