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 Jun 30, 3:39 PM CDT, 1 hour 50 minutes earlier.

Area forecast discussion, Jun 30, 3:39 PM CDT, 1 hour 50 minutes before

Area Forecast Discussion
National Weather Service Lincoln IL
339 PM CDT Mon Jun 30 2014

.DISCUSSION...
ISSUED 338 PM CDT Mon Jun 30 2014

Not many changes overall to the expected weather scenario for the
next week. Discussion will be abbreviated due to ongoing severe
weather preparedness & operations.

SHORT TERM...Tonight through Thursday: Lingering uncertainty
exists with respect to the evolution of the storm complex heading
east across Iowa. Most of forecast area remains in a Moderate Risk
for severe weather through tonight, although the main threat
should be over this evening. Current bow echo, surging east into
northwest Illinois, is expected to stay north of the forecast
area as flow backs southwest ahead of an advancing upper trof.
However, additional development remains possible, and is suggested
by many mesoscale models, along the boundary extending southwest
from the main bow in a strongly sheared and highly unstable
environment. Very heavy rain remains a threat with any storms the
impact the area tonight, with precipitable water values in excess
of 1.5 inches, though rapid storm movement should mitigate the
flooding threat to some degree.

Expect storms to taper off overnight with the loss of diurnal
instability and as the surface cold front sweeps through the area.
The bulk of the remainder of the short term period should be quiet
and cooler than normal. Northwest upper level flow will
predominate, with high pressure at the surface more often than
not. Still signs of a spoke of energy moving through the mean
upper trof around Wednesday, which may bring a chance of rainfall
to the area. However, most of the models are less bullish than
they have been.

LONG TERM...Friday through Monday: Temperatures will begin to
moderate heading into the weekend as low level flow turns
southerly on the back side of the surface high. The turning flow
will also help richer moisture to return to the area. A northwest
flow wave is still expected by late in the weekend, and this will
result in our next organized risk of showers/storms.

.AVIATION...
ISSUED 1255 PM CDT Mon Jun 30 2014

Early morning convection has moved out of the area and dissipated,
leaving behind partly sunny skies. Latest obs generally show MVFR
ceilings and forecast soundings support this for the balance of
the afternoon. Main aviation challenge will be approaching severe
convection later today into tonight. Still quite a bit of
uncertainty concerning exact track and timing: however, storms are
already organizing across western Iowa. High-res model guidance
has a poor handle on the situation, with most solutions appearing
too slow. Based on latest satellite/radar trends, think a line of
strong storms will arrive at KPIA between 23z and 03z...then push
eastward to KCMI between 03z and 07z. Have included a TEMPO group
featuring wind gusts to 45kt at the western terminals accordingly,
but have tempered the winds down to 35kt further east at KDEC and
KCMI as storms should weaken overnight. Once convection clears the
area, skies will clear and winds will become westerly late tonight
into Tuesday morning.
