What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Charleston, SC wrote its last area forecast discussion before this severe thunderstorm warning went out at Jan 22, 5:17 AM EST, 1 hour 18 minutes earlier.

Area forecast discussion, Jan 22, 5:17 AM EST, 1 hour 18 minutes before
Area Forecast Discussion
National Weather Service Charleston SC
517 AM EST Sun Jan 22 2017

.SYNOPSIS...
A strong area of low pressure will develop over the southeast as
it deepens near the southern Appalachians late today and
tonight. This allows for a strong cold front to push through the
area during tonight. Weakening low pressure will pass by to the
north on Monday, before high pressure returns through mid week.
Another cold front will cross the area late in the week.

&&

.NEAR TERM /THROUGH TONIGHT/...
***There remains a risk of severe thunderstorms, including
possible tornadoes through this evening.***

A warm front stretches across the region this morning, situated
near the Savannah River Valley. This feature lifts north of the
area this afternoon, as a wave of low pressure along the front
lifts into NC. A more vigorous low develops over AL and heads
toward the Appalachians in response to a potent and abnormally
deep closed low near the lower MS valley. The surface low
deepens down to near 986 mb by evening, and a trailing cold
front from the low sweeps into and through our forecast area
during the early part of tonight.

A mid level short wave moving through, height falls aloft and
upper divergence with a 100+ upper jet in sync with a 40-45 kt
low level jet will allow for considerable coverage of showers
and t-storms this morning. Although there is minimal surface
based instability, there is sufficient elevated CAPE and
Showalter Indices are -4 to -6C. Plus shear is extremely
impressive, with 0-1 km bulk shear at least 40 kt and 0-1 km
helicity 200-400 m2/sec2 if not higher. As a result there is a
tornado watch in effect for most of our GA counties through 15z.
As such we have mention of damaging winds and/or tornadoes in
the forecast for much of our GA zones, including Savannah,
Hinesville and Springfield. It is possible that the watch may
need to be extended in parts of SC at a later time.

There does appear to be a decrease in convection late this
morning and early this afternoon, as the first short wave pulls
away. This allows for at least some insolation to develop in the
warm sector behind the northward lifting warm front and in
advance of the eastward moving cold front. This will lead to yet
another springlike day, with possible record high temps if there
is enough heating once convection winds down. A few places south
of I-16 in GA could approach 80F, but for most of us mid or
upper 70s will be common. The SC beaches will be the coolest
with a S-SW fetch off the cooler waters.

There remains plenty of dynamics and impressive shear during the
late morning into this evening, but the big question is what
impact or disruption does the morning convection have on
another round of possible severe storms late in the day. The
location and track of both the surface low and that aloft looks
to be displaced a little too far to the W-NW and its movement is
more N-NE rather than E as it draws closer to the CWFA. While
the best QG forcing does stay to our W-NW through the day, and
there is some influx of maritime air into our SC coastal
corridor, there is considerable shear and forcing from both a
50-60 kt low level jet brushing the coast, mid level dry air and
the overall large scale forcing for ascent with impressive
dynamics and upper divergence. This could allow for another and
possibly more widespread round of severe weather from roughly 4
to 10 pm. Provided there is enough destabilization that does
indeed take place and the impressive thermodynamics such as 55
TTI, LI's of -6 to -8 and SBCAPES of 1500-2000 j/kg are
realized. It's hard to gage exactly how this will pan out since
this is extremely unusual for mid winter, but with SHERBS3
values of 1-1.5 and Sig Tor of 3-4 there could be some
additional tornadoes, perhaps even long track supercells as the
Hi-Res models do indicate a possible QLCS moving through late in
the day and this evening.

A noted dry slot will develop behind the cold front as it sweeps
offshore tonight, and rain chances drop off quickly during the
late evening and overnight. However, some late night showers
could move back in across our NW tier as the upper low draws
closer.

There remains a risk for a Wind Advisory for at least the coastal
counties of SC this evening, due to impressive pressure falls as
much as 1-1.5 mb/hr from about 5 pm to 11 pm. That along with a
packed gradient and the passage of a 50-60 kt low level jet
could allow for a few hours of wind gusts near 40 mph.

What is more certain is that winds across Lake Moultrie will
reach at least 20 kt sustained and/or 25 kt gusts this afternoon
through tonight. As a result we have issued a Lake Wind
Advisory.

QPF: There remains a risk for at least minor flooding due to
periods of heavy convective rains today, but also a low end risk
for flash flooding. This is most especially in areas that
received heavy rains yesterday. Large scale forcing and the
PWats that are 150-175% of normal will support an additional -2"
of rain today into tonight, with locally higher amounts.

&&

.SHORT TERM /MONDAY THROUGH WEDNESDAY/...
Monday: A strong low pressure system centered over the western
Carolinas at daybreak will slowly lift northeast through the day.
Some lingering moisture may result in a few light showers in the
morning, then precipitation chances should decrease later in the day
as drier air works into the area. Slight chance PoPs seem
reasonable. A tight pressure gradient will result in gusty west
winds. Gusts up to 35 mph will be possible during peak heating
hours, especially across the southern zones. Deep downslope flow
will keep highs above normal, mainly in the mid 60s. Lows Monday
night in the low to mid 40s.

Tuesday into Wednesday: Weak upper ridging will take place Tuesday
while surface high pressure begins to build into the area. On
Wednesday, the surface high will drift east over Florida and then
into the Atlantic ahead of an approaching cold front. Should be a
quiet and pleasant couple of days. Temperatures will continue to be
above normal, with highs warming from the mid 60s Tuesday to low 70s
on Wednesday.

Lake Winds: Winds will become gusty around and over Lake Moultrie on
Monday. Winds are expected to gust to 25 knots thus a Lake Wind
Advisory is in effect.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/...
A cold front will approach Wednesday night and then cross the area
Thursday. Moisture looks to be fairly limited so current PoP scheme
only features 20-30% chances. High pressure will return in its wake
and persist through much of the weekend. Temperatures above normal
Thursday will finally moderate closer to normal behind the cold
front.

&&

.AVIATION /09Z SUNDAY THROUGH THURSDAY/...
Convective rains will continue to impact KSAV and KCHS this
morning in response to a nearby warm front and significant
large scale forcing. Flight restrictions will be common through
at least 15Z, with SHRA and even the chance for TSRA. Due to a
strong low level jet passing through, we have included LLWS
through the mid morning hours.

For the late morning and into this afternoon the risk for
convection diminishes, and the terminals should improve at least
into the upper end of MVFR weather if not the lower VFR range.
But this may only be temporary as additional convection could
arrive in the form of a squall line late in the day and this
evening. Additional flight restrictions could occur.

It also be a windy day, with mixing tapping into the stronger
winds in the lower levels and a tightening gradient in response
to the upstream low. S-SW winds will reach near 30 kt at times.

Extended Aviation Outlook: Periods of flight restrictions are
likely into Monday. VFR will return thereafter. Gusty winds
will impact the terminals Monday.

&&

.MARINE...
Today: Hazardous weather conditions will develop across the
coastal waters in response to a developing area of low pressure
across GA and AL. While winds will be tempered a little by warm
advection, given 30-40 kt or geostrophic winds at 1000 mb, we
have SCA's in effect for all waters throughout the day,
including Charleston Harbor. S-SW winds will reach as high as
20-30 kt, and seas will build to 4-7 ft within 20 nm and 6-9 ft
across the outer GA waters.

Tonight: The SCA's will transition into a Gale Warning for
AMZ374, and a Gale Watch for AMZ350, but continuing elsewhere.
This occurs with large isallobaric pressure falls followed by
strong height falls aloft. It is possible that the other waters
could also require a Gale Warning at a later time.

Severe Weather: There looks to be two rounds of severe weather
possible; first this morning and the second this evening.
Damaging winds and possible waterspouts are the most common
hazards, although lightning strikes and reduced visibility in
heavy rains will also occur.

Monday through Friday: Hazardous marine conditions will be ongoing
at the start of the period as a strong low pressure system remains
nearby. At least Small Craft Advisories will be in effect for all
waters including the Charleston Harbor. There will be a chance for
gale force gusts, especially in the outer Georgia waters. Will
continue to assess trends. The low will lift northeast away from the
area on Tuesday and winds/seas will begin to subside. High pressure
will build in its wake and prevail through mid week with no marine
issues expected. A cold front will cross the waters Thursday with
another round of small craft advisories possible.
