Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
A large complex of severe thunderstorms developed along a stationary frontal boundary across eastern Iowa during the afternoon of June 30th, then tracked eastward along the boundary across north-central Illinois during the evening. These storms produced locally heavy rainfall along and north of a Canton to Minonk line. Very high rainfall rates led to flash flooding across parts of Marshall and Stark County late on June 30th, with areal flooding into the morning hours of July 1st.

Area Forecast Discussion

.DISCUSSION...
ISSUED 840 PM CDT Mon Jun 30 2014
Initial tornado watch was allowed to expire, as the first wave of
storms passed over the far northern CWA. Some capping has been
keeping storms from firing further south so far this evening,
despite extreme MUCAPE values in the 5000 J/kg vicinity. However,
second line of intense storms currently extending from just west
of Rockford into far southeast Iowa, then back into northwest
Missouri. There will be some battling between the cap in our area
vs the air being worked over already in the north (outflow
boundary has made it between Peoria and Lincoln with temps around
70 north of it). However, the latest HRRR has this lined up fairly
well, and shows the line making it to about Jacksonville and
Bloomington between 10-11 pm albeit in a weakening state. Have
updated the grids to significantly beef up the PoP's and rain
totals in the northwest this evening, and refined the southern
extent. Will send out corresponding zones shortly.

.AVIATION...
ISSUED 1236 AM CDT Tue Jul 1 2014
Outside any thunderstorm, VFR conditions are expected this TAF
period. Scattered storms continue to push across central IL and
will affect the area through 08z with occasional MVFR cigs and
vsbys. Once the storms shift out of the area, a cold front
currently out to our west, will push thru the region by dawn
Tuesday. There is a low probability for lowering vsbys in fog just
ahead of the front as winds drop off for several hours but
confidence on that is too loo at this time to add into the
forecast. Surface winds behind the main outflow boundary will be
variable in direction up to 15 kts at times, and then more of a
south to southwest flow is expected ahead of the front. During the
day Tuesday, southwest to west winds are expected to increase to
12 to 17 kts by afternoon.

.PREV 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.
