What forecasters said that day

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

NWS Quad Cities, IA wrote its last area forecast discussion before this winter storm warning went out at Feb 7, 11:17 PM CST, 3 hours 42 minutes earlier.

Area forecast discussion, Feb 7, 11:17 PM CST, 3 hours 42 minutes before
Area Forecast Discussion...UPDATED
National Weather Service Quad Cities IA IL
1117 PM CST Wed Feb 7 2018

...06z AVIATION UPDATE...

.SYNOPSIS...
Issued at 321 PM CST Wed Feb 7 2018

18Z surface data has high pressure from the upper Midwest into the
southern Plains. Dew points were in the single digits above and
below zero from the Great Lakes into the central Plains. Dew points
in the teens and higher ran from the Ohio Valley into the southern
Plains and Gulf Coast.

&&

.SHORT TERM...(This Evening through Thursday)
ISSUED AT 321 PM CST Wed Feb 7 2018

Quiet, cold, and dry conditions will be seen from late this
afternoon through the evening hours.

After midnight, a weak upper level disturbance will move through the
area. Moisture is quite limited but it will be moving over a
modified arctic air mass. The forcing supplied by the disturbance
will allow light snow to develop.

Accumulations late tonight will range from a trace to a dusting.

On Thursday, very light snow or flurries will continue during the
morning generally north of I-80 before ending. Attention then turns
to the more significant storm system.

Thursday afternoon, moisture aloft will move into the area. As
forcing from the approaching storm system increases, snow will
develop/move into the area especially north of an Aledo, IL to
Sigourney, IA line. By sunset Thursday snow accumulations
along/north of I-80 will range from a trace to under an inch.

.LONG TERM...(Thursday Night through Wednesday)
ISSUED AT 321 PM CST Wed Feb 7 2018

Thursday Evening through Friday

Snow Potential:

Issued a Winter Storm Watch for the counties approximately along and
north of I-80, from Thursday midday afternoon through Friday, for
the potential of 4 to 8 inches of snow.

The favored area for the highest snowfall is in the counties along
the Mississippi River and along/north of highway 30. However, due to
model differences, and since this is 24-36 hours away, there is
still uncertainty regarding exact snowfall amounts and the placement
of the heaviest snow band. As confidence increases with later
forecast updates, expect the Winter Storm Watch to be replaced by
either a Winter Weather Advisory or Winter Storm Warning. Later
forecast shifts will also have to look at the potential for
instability aloft leading to localized higher snowfall amounts than
currently forecast within a narrow zone.

Impacts:

Roads will quickly become snow covered and slippery late Thursday
afternoon and into the evening due to cold pavement temperatures.
Additionally, periods of moderate or heavy snow will reduce
visibilities to under a half mile at times. Light winds should
preclude significant drifting of snow for the majority of the event.
With that said, an increase in NW winds Friday afternoon to between
15-20 mph may result in areas of blowing and drifting snow as the
storm winds down.

Environmental Setup and Model Trends:

Elevated warm air advection and increasing low to mid-level
frontogenetic forcing beneath the right entrance region of an upper-
level jet streak will lead to a band of snow developing across
portions of the forecast area Thursday afternoon and evening. A
closed 850mb low will cause the snow band to spread east initially,
then potentially shift to the north before pivoting back to the
southeast and overspreading the remainder of the CWA.

Overall it should be a dry snow, but not powdery. Forecast soundings
have the lowest 3km layer warmer than the DGZ. This restricts the
saturated DGZ to a depth of only 50-100mb. For this reason, and
incorporating Cobb output, thinking snow ratios near climatology of
12-16:1 are reasonable for an event average.

The ECMWF/NAM/SREF have the heaviest snow across the NE forecast
area which is in line with our current forecast. Other models, like
the CMC/GFS/3km NAM, are further south and focus the heavy snow band
along I-80, keeping the highest amounts in the counties along and
east of the Mississippi River. Current forecast is weighted slightly
more toward the northern models.

Saturday

After a brief break Friday night, yet another round of accumulating
snow is likely Saturday into Saturday night as a mid-level trough
crosses the Midwest and Western Great Lakes area. Several inches are
likely which may require a new set of winter headlines. Right now,
the favored area for the highest amounts are south of I-80.

Sunday On

Fresh snow cover will keep temperatures near or below normal into
early next week. There is a slight chance for light precipitation on
Tuesday as a weak trough passes through.

&&

.AVIATION...(For the 06Z TAFS through 06Z Thursday Night)
ISSUED AT 1110 PM CST Wed Feb 7 2018

VFR conditions to continue through most of the period with
exception of light snow at CID and DBQ late tonight. At the end of
a the period a winter storm is expected and will result in IFR and
possibly LIFR cigs and vsbys later today and overnight into
Friday. Cig impacts expected to air travel likely after 00z
Friday.

Advisory or a Winter Storm Warning.

Saturday night as a mid level disturbance moves across the region.
Several inches of snow is possible and winter weather headlines
are possible. At the moment, the favored area for accumulating
snow is south of Interstate 80.
