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 Lincoln, IL wrote its last area forecast discussion before this severe thunderstorm warning went out at Feb 20, 3:22 PM CST, 39 minutes earlier.

Area forecast discussion, Feb 20, 3:22 PM CST, 39 minutes before

Area Forecast Discussion
National Weather Service Lincoln IL
322 PM CST Thu Feb 20 2014

.DISCUSSION...
ISSUED 320 PM CST Thu Feb 20 2014

Short term issues revolve around a rapidly deepening low pressure
system passing across far NW IL this afternoon, with a cold front
racing across IL and into Indiana by 7 pm. Severe weather
potential will progress east along and south of the warm front.
Areas of very dense fog should dissipate behind the cold front as
well.

Very strong winds will develop as pressure rises reach 12mb per 3
hours. Wind speeds of 30-40 mph and gusts over 55 mph will develop
shortly after the cold front passes. Flooding is already occurring
across Knox and Stark counties where 2-2.5" of rain already fell
earlier today. More rain from the line of thunderstorms could
aggravate the flooding.

Beyond the very busy short term, we have various short waves
expected to move across IL between Friday night and Monday night.
With the colder air also arriving this weekend, most of any
precipitation that does develop should fall as snow. The models
are producing widely varying solutions as to amount and coverage
of any precip during that time, but we wanted to at least
acknowledge the potential for precip due to at least 2 models
showing some precipitation produced by each wave.

SHORT TERM...Tonight through Sunday.

A line of storms will race across IL just ahead of the cold front.
Forward motion of the storms is being measured at 60 mph, with a
low level jet of 70 kts just above the LCL. Storms are moving from
to the N-NE towards areas with snow cover and more stable air near
the ground. We expect to see localized damaging winds from the
storm gust fronts in areas along and south of the warm front,
which generally extends from Galesburg to Bloomington at this
point. Isolated tornadoes could develop as wind shear rapidly
increases just ahead of the cold front.

As storms move farther north over snow covered areas, storms should
begin to lose the ability to blast damaging winds through the
stable low level airmass to the ground. The severe thunderstorm
watch goes until 6 pm for out SW counties, but an additional watch
will likely be needed farther east and south of the warm front as
the cold front moves across IL.

Dense fog has caused travel hazards for areas north of Rushville
to Lincoln to Bloomington, and a dense fog advisory will go
through 6 pm.

Shortly behind the cold front, very strong pressure rises will
produce very strong winds for several hours, with the strongest
gusts possibly as high as 60 mph in the first 3-4 hours behind the
front. Pressure rises diminish somewhat later this evening, but
sustained winds will likely remain around 30 mph gusting to 40 mph
at times until midnight. We may be able to remove some of the
wind warning headline a little before 3 am as conditions warrant.

A band of light rain or snow may move into our west-northwestern
counties this evening through just after midnight, but little to
no snow accumulation is expected.

The axis of coldest air behind the cold front will pass across our
forecast area around 12z/6am Friday morning. Clouds will begin to
clear out of our SW areas around that time, but lows should still
remain in the mid 20s north and upper 20 south. Warming occurs
through the day on Friday, as 850mb temps climb from -8C or -9C at 6
am to zero to -2C at 6 pm. West-southwest winds will remain brisk
and help to push high temps into the 40s across the board.

The first shortwave that could produce some light snow is forecast
to arrive Friday night. The GFS and Canadian have been
consistently showing that feature and a dusting to a half inch of
snow across the northern counties. The 12z Canadian did back off a
little on the QPF, but the 12z ECMWF has started pointing towards
forcing for precip during that time over that area as well.

The airmass cools down for Saturday, as high pressure builds into
IL from the NW. The GFS and Canadian once again team up on a
shortwave for Sunday, producing 0.5" to 1" of snow across our W
and N counties. The NAM indicates some snow for our southeastern
counties Sunday afternoon, while the ECMWF is not resolving that
feature as well.

More noticeably cooler highs are forecast for Sunday as readings
top out about 10-12F degrees colder than Saturday.

LONG TERM...Monday through Thursday.

The third shortwave is projected to arrive later Monday morning or
Monday afternoon. There is some agreement on this by the GFS,
Canadian, and ECMWF. With 3 models in general agreement, we
increased PoPs into the chance category across the north, for
another 0.5 to 1" of snow through early Monday evening.

A stronger push of cold air will arrive behind that wave, as 850mb
temps drop to -16C to -18C by Tuesday evening. Lows should reach
into the single digits above zero north of Peoria to Bloomington
Tues night, with single digits N of I-70 Wed night. The coldest
highs this week look to be on Thursday as readings remain in the
teens north of a line from Rushville to Champaign.

Light snow may return late next Thursday afternoon and Thursday
night as yet another shortwave pushes into the area.

.AVIATION...
ISSUED 1155 AM CST Thu Feb 20 2014

Warm front has lifted just north of KSPI/KDEC/KCMI, shifting winds
back around to the south and gusting to around 25-30 knots, while
east winds around 10 knots continue further north. Should see the
front continue to lift northward over the next couple of hours.
Have had some areas of dense fog primarily north of the front, as
a significant increase in low level moisture moves in with the
front, but this is likely to fade out in the next couple hours.
Line of convection starting to form in central Missouri, and will
move east through central Illinois mid to late afternoon. Have
included about a 3 hour period of VCTS at each TAF site for now,
and will update later to narrow down the time frame once the line
becomes more mature. A cold front will pass by shortly behind the
line of storms, switching winds to the west. Still looks like
gusts of 35-45 knots will be likely this evening, as impressive
pressure rises spread across the state in the wake of a deepening
low pressure passage. Wraparound snow showers may spread as far
south as KPIA/KBMI after 06Z. Have maintained the MVFR conditions
through the night, before improvement early Friday morning. Winds
by Friday morning not quite as high, but still gusting in the 30
knot vicinity.
